SQL: Update max values with min values in same table - sql

I have a table with a priority. Something like that:
id priority name
-------------------------------
1 5 SomeFunnyName
2 10 SomeFunnyName1
3 20 SomeFunnyName2
4 30 SomeFunnyName3
5 40 SomeFunnyName4
Data with higher priority was proceeded faster. But now i have to change the priority logic. So data with lower priority will proceed faster.
How can i update this table that the data with the highest priority will now have the lowest priority?


When you multiply by minus one it would change the priority, this way you can revert back easily by again multiplying by minus one
UPDATE TABLE SET PRIORITY=-1*PRIORITY


You can try to use MAX and MIN get priority and some calculation to make it change the MAX and MIN priority from the table.
CREATE TABLE T(
id int,
priority int,
name varchar(50)
);
insert into t values (1,5,'SomeFunnyName');
insert into t values (2,10,'SomeFunnyName1');
insert into t values (3,20,'SomeFunnyName2');
insert into t values (4,30,'SomeFunnyName3');
insert into t values (5,40,'SomeFunnyName4');
UPDATE T
Set priority = maxVal - priority + minVal
FROM (
SELECT MAX(priority) maxVal,MIN(priority) minVal
FROM T
) t1
Query 1:
SELECT * FROM T
Results:
| id | priority | name |
|----|----------|----------------|
| 1 | 40 | SomeFunnyName |
| 2 | 35 | SomeFunnyName1 |
| 3 | 25 | SomeFunnyName2 |
| 4 | 15 | SomeFunnyName3 |
| 5 | 5 | SomeFunnyName4 |

SQL - Set column value to the SUM of all references

I want to have the column "CurrentCapacity" to be the SUM of all references specific column.
Lets say there are three rows in SecTable which all have FirstTableID = 1. Size values are 1, 1 and 3.
The row in FirstTable which have ID = 1 should now have a value of 5 in the CurrentCapacity column.
How can I make this and how to do automatically on insert, update and delete?
Thanks!
FirstTable
+----+-------------+-------------------------+
| ID | MaxCapacity | CurrentCapacity |
+----+-------------+-------------------------+
| 1 | 5 | 0 (desired result = 5) |
+----+-------------+-------------------------+
| 2 | 5 | 0 |
+----+-------------+-------------------------+
| 3 | 5 | 0 |
+----+-------------+-------------------------+
SecTable
+----+-------------------+------+
| ID | FirstTableID (FK) | Size |
+----+-------------------+------+
| 1 | 1 | 2 |
+----+-------------------+------+
| 2 | 1 | 3 |
+----+-------------------+------+

In general, a view is a better solution than trying to keep a calculated column up-to-date. For your example, you could use this:
CREATE VIEW capacity AS
SELECT f.ID, f.MaxCapacity, COALESCE(SUM(s.Size), 0) AS CurrentCapacity
FROM FirstTable f
LEFT JOIN SecTable s ON s.FirstTableID = f.ID
GROUP BY f.ID, f.MaxCapacity
Then you can simply
SELECT *
FROM capacity
to get the results you desire. For your sample data:
ID MaxCapacity CurrentCapacity
1 5 5
2 5 0
3 5 0
Demo on SQLFiddle

Got this question to work with this trigger:
CREATE TRIGGER UpdateCurrentCapacity
ON SecTable
AFTER INSERT, UPDATE, DELETE
AS
BEGIN
SET NOCOUNT ON
DECLARE #Iteration INT
SET #Iteration = 1
WHILE #Iteration <= 100
BEGIN
UPDATE FirstTable SET FirstTable.CurrentCapacity = (SELECT COALESCE(SUM(SecTable.Size),0) FROM SecTable WHERE FirstTableID = #Iteration) WHERE ID = #Iteration;
SET #Iteration = #Iteration + 1
END
END
GO

Personally, I would not use a trigger either or store CurrentCapacity as a value since it breaks Normalization rules for database design. You have a relation and can already get the results by creating a view or setting CurrentCapacity to a calculated column.
Your view can look like this:
SELECT Id, MaxCapacity, ISNULL(O.SumSize,0) AS CurrentCapacity
FROM dbo.FirstTable FT
OUTER APPLY
(
SELECT ST.FirstTableId, SUM(ST.Size) as SumSize FROM SecTable ST
WHERE ST.FirstTableId = FT.Id
GROUP BY ST.FirstTableId
) O
Sure, you could fire a proc every time a row is updated/inserted or deleted in the second table and recalculate the column, but you might as well calculate it on the fly. If it's not required to have the column accurate, you can have a job update the values every X hours. You could combine this with your view to have both a "live" and "cached" version of the capacity data.

How to make query that will return differences between two tables in PostgreSQL

I need to return differences between two tables.
CREATE TEMPORARY TABLES
CREATE TEMP TABLE first(
zoom smallint NOT NULL,
x integer NOT NULL,
y integer NOT NULL
);
CREATE TEMP TABLE second(
zoom smallint NOT NULL,
x integer NOT NULL,
y integer NOT NULL
);
INSERT DATA
INSERT INTO first(zoom,x,y) VALUES(5,2,25);
INSERT INTO first(zoom,x,y) VALUES(5,4,45);
INSERT INTO first(zoom,x,y) VALUES(5,7,34);
INSERT INTO first(zoom,x,y) VALUES(5,45,40);
INSERT INTO first(zoom,x,y) VALUES(5,72,63);
INSERT INTO second(zoom,x,y) VALUES(5,2,25);
INSERT INTO second(zoom,x,y) VALUES(5,4,45);
INSERT INTO second(zoom,x,y) VALUES(5,7,34);
Wanted result:
In table first there are extra rows:
5,45,40
5,72,63
Edit
Sorry about this, but I have figured out now that my original data is pretty much complexed then the sample I provided. So in the original data, table first consists of 900 rows, and table second of 935 rows. I assumed that the rows are distinct in each table, however as I am not sure now, so I would like to include this condition in a query. I assumed query would return 35 rows as difference, because I was pretty much convinced that all zoom/x/y would be same except this 35 one. However, it might now be the case. So basically what I need to know is what are differences between two tables, whatever approach is the best to solve it.
Can I get something like this:
zoom | x | y | first |second
------+----+--- +-------+------
5 | 45 | 40 | yes | no |
order by first yes, second no
zoom | x | y | first |second
------+----+--- +-------+------
5 | 45 | 40 | yes | no |
5 | 45 | 40 | yes | no |
5 | 45 | 40 | yes | no |
then first no, second yes
zoom | x | y | first |second
------+----+--- +-------+------
5 | 45 | 40 | no | yes |
5 | 45 | 40 | no | yes |
5 | 45 | 40 | no | yes |

You can use EXCEPT
select zoom,x,y from first
except
select zoom,x,y from second
or am missing something here
If you want non matching records from both the tables then
select * from
(
select zoom,x,y from first
except
select zoom,x,y from second
) a
union all
select * from
(
select zoom,x,y from second
except
select zoom,x,y from first
) b

As you want to compare all columns of both tables, you can use a full outer join on all columns and the check if one of them is:
select case
when f.zoom is null then 'missing in first'
when s.zoom is null then 'missing in second'
end as status,
zoom, x, y
from "first" f
full outer join second s using (zoom, x, y)
where f.zoom is null or s.zoom is null;
The join based on using() will return those columns that are not null (and only those columns - removing the duplicate columns from the result)
When using your sample data from the question, the result would be:
status | zoom | x | y
------------------+------+----+---
missing in second | 5 | 45 | 40
missing in second | 5 | 72 | 63
If a row in the second table is added that doesn't exist in the first, e.g.:
INSERT INTO second(zoom,x,y) VALUES(15,7,34);
then the result will be:
status | zoom | x | y
------------------+------+----+---
missing in second | 5 | 45 | 40
missing in second | 5 | 72 | 63
missing in first | 15 | 7 | 34

Here is one method:
select max(which) as AppearsIn, x, y, zoom
from ((select 'first' as which, x, y, zoom from first) union all
(select 'second', x, y, zoom from second)
) x
group by x, y, zoom
having count(*) = 1;
This assumes that the rows are distinct in each table.

If you also want possible duplicate mismatches, you should count them:
SELECT COALESCE(f.zoom,s.zoom) AS zoom
, COALESCE(f.x,s.x) AS x
, COALESCE(f.y,s.y) AS y
, COALESCE(f.fcnt,0) AS fcnt
, COALESCE(s.scnt,0) AS scnt
FROM ( SELECT DISTINCT zoom,x,y
, COUNT (*) AS fcnt
FROM first
GROUP BY zoom,x,y
) f
FULL OUTER JOIN ( SELECT DISTINCT zoom,x,y
, COUNT (*) AS scnt
FROM second
GROUP BY zoom,x,y
) s USING (zoom,x,y)
WHERE f.fcnt IS NULL OR s.scnt IS NULL
;

TSQL SSRS Cross Reference another column

ID | Col2 | Col3 | SequenceNum
--------------------------------
1 | x | 12 | 5
2 | y | 11 | 6
3 | a | 45 | 7
100 | b | 23 | 8
101 | a | 16 | 9
102 | b | 28 | 10
4 | a | 9 | 11
5 | b | 26 | 12
6 | x | 100 | 13
I have an SSRS report at the moment which you can enter the ID for and it'll show you data for those ID's. For example lets say you enter start ID 2 end ID 5 it'll report back 2,3,4,5 with Col2 and Col3 data.
But what I really want to happen is for it to return 2,3,100,101,102,3,4,5
I believe may be some way to cross reference the SequenceNum column but I'm fairly new to SQL and SSRS can anyone help?
So an user would enter a parameters...
start-ID = 2 which has a SequenceNum of 6
and end-ID = 5 which has an SequenceNum of 12

Extract your starting and ending sequence numbers from value supplied by starting id and ending id respectively and use them in WHERE condition as below
DECLARE #StartingSeqNum INT, #EndingSeqNum
SELECT #StartingSeqNum = SeqNum FROM tableName WHERE ID = #start_id
SELECT #EndingSeqNum = SeqNum FROM tableName WHERE ID = #end_id
SELECT Col2,Col3
FROM tableName
WHERE SeqNum BETWEEN #StartingSeqNum AND #EndingSeqNum

As you are using SSRS you can specify a Value and a Label for your parameters.
Create a dataset with the following SQL as the source:
select distinct ID as Label
,SequenceNum as Value
from YourTable
order by SequenceNum
And then in the properties for your parameter, in Available Values select Get values from query and then select the above dataset. Set the Value field and Label field as your label and value columns and then click OK. You will need to do this for your start and end parameters, using the same dataset.
Your parameters will now be drop down menus that display the ID value to the user, but passes the SequenceNum value to your query. You can then use these to filter your main dataset.

Insert into multiple tables

A brief explanation on the relevant domain part:
A Category is composed of four data:
Gender (Male/Female)
Age Division (Mighty Mite to Master)
Belt Color (White to Black)
Weight Division (Rooster to Heavy)
So, Male Adult Black Rooster forms one category. Some combinations may not exist, such as mighty mite black belt.
An Athlete fights Athletes of the same Category, and if he classifies, he fights Athletes of different Weight Divisions (but of the same Gender, Age and Belt).
To the modeling. I have a Category table, already populated with all combinations that exists in the domain.
CREATE TABLE Category (
[Id] [int] IDENTITY(1,1) NOT NULL,
[AgeDivision_Id] [int] NULL,
[Gender] [int] NULL,
[BeltColor] [int] NULL,
[WeightDivision] [int] NULL
)
A CategorySet and a CategorySet_Category, which forms a many to many relationship with Category.
CREATE TABLE CategorySet (
[Id] [int] IDENTITY(1,1) NOT NULL,
[Championship_Id] [int] NOT NULL,
)
CREATE TABLE CategorySet_Category (
[CategorySet_Id] [int] NOT NULL,
[Category_Id] [int] NOT NULL
)
Given the following result set:
| Options_Id | Championship_Id | AgeDivision_Id | BeltColor | Gender | WeightDivision |
|------------|-----------------|----------------|-----------|--------|----------------|
1. | 2963 | 422 | 15 | 7 | 0 | 0 |
2. | 2963 | 422 | 15 | 7 | 0 | 1 |
3. | 2963 | 422 | 15 | 7 | 0 | 2 |
4. | 2963 | 422 | 15 | 7 | 0 | 3 |
5. | 2964 | 422 | 15 | 8 | 0 | 0 |
6. | 2964 | 422 | 15 | 8 | 0 | 1 |
7. | 2964 | 422 | 15 | 8 | 0 | 2 |
8. | 2964 | 422 | 15 | 8 | 0 | 3 |
Because athletes may fight two CategorySets, I need CategorySet and CategorySet_Category to be populated in two different ways (it can be two queries):
One Category_Set for each row, with one CategorySet_Category pointing to the corresponding Category.
One Category_Set that groups all WeightDivisions in one CategorySet in the same AgeDivision_Id, BeltColor, Gender. In this example, only BeltColor varies.
So the final result would have a total of 10 CategorySet rows:
| Id | Championship_Id |
|----|-----------------|
| 1 | 422 |
| 2 | 422 |
| 3 | 422 |
| 4 | 422 |
| 5 | 422 |
| 6 | 422 |
| 7 | 422 |
| 8 | 422 |
| 9 | 422 | /* groups different Weight Division for BeltColor 7 */
| 10 | 422 | /* groups different Weight Division for BeltColor 8 */
And CategorySet_Category would have 16 rows:
| CategorySet_Id | Category_Id |
|----------------|-------------|
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 5 |
| 6 | 6 |
| 7 | 7 |
| 8 | 8 |
| 9 | 1 | /* groups different Weight Division for BeltColor 7 */
| 9 | 2 | /* groups different Weight Division for BeltColor 7 */
| 9 | 3 | /* groups different Weight Division for BeltColor 7 */
| 9 | 4 | /* groups different Weight Division for BeltColor 7 */
| 10 | 5 | /* groups different Weight Division for BeltColor 8 */
| 10 | 6 | /* groups different Weight Division for BeltColor 8 */
| 10 | 7 | /* groups different Weight Division for BeltColor 8 */
| 10 | 8 | /* groups different Weight Division for BeltColor 8 */
I have no idea how to insert into CategorySet, grab it's generated Id, then use it to insert into CategorySet_Category
I hope I've made my intentions clear.
I've also created a SQLFiddle.
Edit 1: I commented in Jacek's answer that this would run only once, but this is false. It will run a couple of times a week. I have the option to run as SQL Command from C# or a stored procedure. Performance is not crucial.
Edit 2: Jacek suggested using SCOPE_IDENTITY to return the Id. Problem is, SCOPE_IDENTITY returns only the last inserted Id, and I insert more than one row in CategorySet.
Edit 3: Answer to #FutbolFan who asked how the FakeResultSet is retrieved.
It is a table CategoriesOption (Id, Price_Id, MaxAthletesByTeam)
And tables CategoriesOptionBeltColor, CategoriesOptionAgeDivision, CategoriesOptionWeightDivison, CategoriesOptionGender. Those four tables are basically the same (Id, CategoriesOption_Id, Value).
The query look like this:
SELECT * FROM CategoriesOption co
LEFT JOIN CategoriesOptionAgeDivision ON
CategoriesOptionAgeDivision.CategoriesOption_Id = co.Id
LEFT JOIN CategoriesOptionBeltColor ON
CategoriesOptionBeltColor.CategoriesOption_Id = co.Id
LEFT JOIN CategoriesOptionGender ON
CategoriesOptionGender.CategoriesOption_Id = co.Id
LEFT JOIN CategoriesOptionWeightDivision ON
CategoriesOptionWeightDivision.CategoriesOption_Id = co.Id

The solution described here will work correctly in multi-user environment and when destination tables CategorySet and CategorySet_Category are not empty.
I used schema and sample data from your SQL Fiddle.
First part is straight-forward
(ab)use MERGE with OUTPUT clause.
MERGE can INSERT, UPDATE and DELETE rows. In our case we need only to INSERT. 1=0 is always false, so the NOT MATCHED BY TARGET part is always executed. In general, there could be other branches, see docs. WHEN MATCHED is usually used to UPDATE; WHEN NOT MATCHED BY SOURCE is usually used to DELETE, but we don't need them here.
This convoluted form of MERGE is equivalent to simple INSERT, but unlike simple INSERT its OUTPUT clause allows to refer to the columns that we need.
MERGE INTO CategorySet
USING
(
SELECT
FakeResultSet.Championship_Id
,FakeResultSet.Price_Id
,FakeResultSet.MaxAthletesByTeam
,Category.Id AS Category_Id
FROM
FakeResultSet
INNER JOIN Category ON
Category.AgeDivision_Id = FakeResultSet.AgeDivision_Id AND
Category.Gender = FakeResultSet.Gender AND
Category.BeltColor = FakeResultSet.BeltColor AND
Category.WeightDivision = FakeResultSet.WeightDivision
) AS Src
ON 1 = 0
WHEN NOT MATCHED BY TARGET THEN
INSERT
(Championship_Id
,Price_Id
,MaxAthletesByTeam)
VALUES
(Src.Championship_Id
,Src.Price_Id
,Src.MaxAthletesByTeam)
OUTPUT inserted.id AS CategorySet_Id, Src.Category_Id
INTO CategorySet_Category (CategorySet_Id, Category_Id)
;
FakeResultSet is joined with Category to get Category.id for each row of FakeResultSet. It is assumed that Category has unique combinations of AgeDivision_Id, Gender, BeltColor, WeightDivision.
In OUTPUT clause we need columns from both source and destination tables. The OUTPUT clause in simple INSERT statement doesn't provide them, so we use MERGE here that does.
The MERGE query above would insert 8 rows into CategorySet and insert 8 rows into CategorySet_Category using generated IDs.
Second part
needs temporary table. I'll use a table variable to store generated IDs.
DECLARE #T TABLE (
CategorySet_Id int
,AgeDivision_Id int
,Gender int
,BeltColor int);
We need to remember the generated CategorySet_Id together with the combination of AgeDivision_Id, Gender, BeltColor that caused it.
MERGE INTO CategorySet
USING
(
SELECT
FakeResultSet.Championship_Id
,FakeResultSet.Price_Id
,FakeResultSet.MaxAthletesByTeam
,FakeResultSet.AgeDivision_Id
,FakeResultSet.Gender
,FakeResultSet.BeltColor
FROM
FakeResultSet
GROUP BY
FakeResultSet.Championship_Id
,FakeResultSet.Price_Id
,FakeResultSet.MaxAthletesByTeam
,FakeResultSet.AgeDivision_Id
,FakeResultSet.Gender
,FakeResultSet.BeltColor
) AS Src
ON 1 = 0
WHEN NOT MATCHED BY TARGET THEN
INSERT
(Championship_Id
,Price_Id
,MaxAthletesByTeam)
VALUES
(Src.Championship_Id
,Src.Price_Id
,Src.MaxAthletesByTeam)
OUTPUT
inserted.id AS CategorySet_Id
,Src.AgeDivision_Id
,Src.Gender
,Src.BeltColor
INTO #T(CategorySet_Id, AgeDivision_Id, Gender, BeltColor)
;
The MERGE above would group FakeResultSet as needed and insert 2 rows into CategorySet and 2 rows into #T.
Then join #T with Category to get Category.IDs:
INSERT INTO CategorySet_Category (CategorySet_Id, Category_Id)
SELECT
TT.CategorySet_Id
,Category.Id AS Category_Id
FROM
#T AS TT
INNER JOIN Category ON
Category.AgeDivision_Id = TT.AgeDivision_Id AND
Category.Gender = TT.Gender AND
Category.BeltColor = TT.BeltColor
;
This will insert 8 rows into CategorySet_Category.

Here is not the full answer, but direction which you can use to solve this:
1st query:
select row_number() over(order by t, Id) as n, Championship_Id
from (
select distinct 0 as t, b.Id, a.Championship_Id
from FakeResultSet as a
inner join
Category as b
on
a.AgeDivision_Id=b.AgeDivision_Id and
a.Gender=b.Gender and
a.BeltColor=b.BeltColor and
a.WeightDivision=b.WeightDivision
union all
select distinct 1, BeltColor, Championship_Id
from FakeResultSet
) as q
2nd query:
select q2.CategorySet_Id, c.Id as Category_Id from (
select row_number() over(order by t, Id) as CategorySet_Id, Id, BeltColor
from (
select distinct 0 as t, b.Id, null as BeltColor
from FakeResultSet as a
inner join
Category as b
on
a.AgeDivision_Id=b.AgeDivision_Id and
a.Gender=b.Gender and
a.BeltColor=b.BeltColor and
a.WeightDivision=b.WeightDivision
union all
select distinct 1, BeltColor, BeltColor
from FakeResultSet
) as q
) as q2
inner join
Category as c
on
(q2.BeltColor is null and q2.Id=c.Id)
OR
(q2.BeltColor = c.BeltColor)
of course this will work only for empty CategorySet and CategorySet_Category tables, but you can use select coalese(max(Id), 0) from CategorySet to get current number and add it to row_number, thus you will get real ID which will be inserted into CategorySet row for second query

What I do when I run into these situations is to create one or many temporary tables with row_number() over clauses giving me identities on the temporary tables. Then I check for the existence of each record in the actual tables, and if they exist update the temporary table with the actual record ids. Finally I run a while exists loop on the temporary table records missing the actual id and insert them one at a time, after the insert I update the temporary table record with the actual ids. This lets you work through all the data in a controlled manner.

##IDENTITY is your friend to the 2nd part of question
https://msdn.microsoft.com/en-us/library/ms187342.aspx
and
Best way to get identity of inserted row?
Some API (drivers) returns int from update() function, i.e. ID if it is "insert". What API/environment do You use?
I don't understand 1st problem. You should not insert identity column.

Below query will give final result For CategorySet rows:
SELECT
ROW_NUMBER () OVER (PARTITION BY Championship_Id ORDER BY Championship_Id) RNK,
Championship_Id
FROM
(
SELECT
Championship_Id
,BeltColor
FROM #FakeResultSet
UNION ALL
SELECT
Championship_Id,BeltColor
FROM #FakeResultSet
GROUP BY Championship_Id,BeltColor
)BASE

Reducing values in one table until reserves depleted in another - recursion?

I have two tables - let's call them dbo.ValuesToReduce and dbo.Reserve
The data in the first table (dbo.ValuesToReduce) is:
ValuesToReduceId | PartnerId | Value
-------------------------------------
1 | 1 | 53.15
2 | 2 | 601.98
3 | 1 | 91.05
4 | 2 | 44.56
5 | 3 | 19.11
The second table (dbo.Reserve) looks like this
ReserveId | PartnerId | Value
-------------------------------
1 | 1 | -101.55
2 | 2 | -425.19
3 | 3 | -28.17
What I need to do is: update the Values in ValuesToReduce table using the latter table of Reserves, reducing the numbers until the reserve supply is exhausted. Here's what I should get after running the script:
ValuesToReduceId | PartnerId | Value
-------------------------------------
1 | 1 | 0.00
2 | 2 | 176.79
3 | 1 | 42.65
4 | 2 | 44.56
5 | 3 | 0.00
ReserveId | PartnerId | Value
-------------------------------
1 | 1 | 0.00
2 | 2 | 0.00
3 | 3 | -9.06
So basically, every partner has a "reserve" which he can deplete, and values in the value table should be reduced by partner accordingly if there is still something in the reserves. Reserves should be collocated in the order provided by ValuesToReduceId.
For partner with PartnerId of 1, you can see that he had enough reserve to update his first value to 0 and still had some left to reduce the second value by that amount.
Partner with ID of 2 had a reserve of 425.19, and there were two entries in the values table for that partner, 601.98 and 44.56, in that order (by ValuesToReduceId), so we only updated the first value since the reserve is not big enough for both. The wrong way would have been to update the second value to 0.00 and the first to 221.35.
Partner with ID of 3 has more than enough reserve, so after updating his value to 0, he's left with -9.06
I tried something with recursive cte, but I can't seem to get my head around it.
Hope I described the problem clearly enough..

You cannot, as far as I know, update two tables in a single select statement.
But you could do this in SQL using a WHILE loop. Search for the first transaction, then carry it out, until there are no possible transactions left.
declare #valid int
declare #resid int
declare #val float
while 1 = 1
begin
select top 1
#resid = r.ReserveId
, #valid = v.ValuesToReduceId
, #val = CASE WHEN -r.Value > v.Value THEN v.Value ELSE -r.Value END
from ValuesToReduce v
inner join Reserves r on r.PartnerId = v.PartnerId
where r.Value < 0 and v.Value > 0
order by r.ReserveId
if ##rowcount = 0
break
update ValuesToReduce
set Value = Value - #val
where ValuesToReduceId = #valid
update Reserves
set Value = Value + #val
where ReserveId = #resid
end
Here's code to create test tables:
create table ValuesToReduce (
ValuesToReduceId int,
PartnerId int,
Value float
)
insert into ValuesToReduce values (1,1,53.15)
insert into ValuesToReduce values (2,2,601.98)
insert into ValuesToReduce values (3,1,91.05)
insert into ValuesToReduce values (4,2,44.56)
insert into ValuesToReduce values (5,3,19.11)
create table Reserves (
ReserveId int,
PartnerId int,
Value float
)
insert into Reserves values (1,1,-101.55)
insert into Reserves values (2,2,-425.19)
insert into Reserves values (3,3,-28.17)
