Ignore other fields, I need to delete all raws in Tabel 1 where AMT in Tabel 2 has zero or no value for the SALESID.
For example, after the query, only raws containing 1AX & 4DZ should be remain in Tabel 1.
this can be done by subquery
get all MainID from table2 where amt is 0 or null
delete all rows that equal to previous fetched MainID
delete from table1 where MainID in (
select SALESID from table2 where AMT <=0 or AMT is null
)
You can use exists:
delete from table1
where exists (select 1
from table2 t2
where table1.mainid = t2.salesid and
(t2.amt = 0 or t2.amt is null)
);
Thinking an INNER JOIN would be much faster on larger data sets. Something like this:
DELETE
T1
FROM
Table1 T1
INNER JOIN
Table2 T2 ON T2.SalesID = T1.MainID
WHERE
IsNull(T2.Amt,0) = 0

I've been struggling with this problem.
I have 2 populated tables and a third empty one and I would like to populate the third with data from the other two. Correlate values
The idea is to assign every single ID from the 1st table to entries (several) found in the 2nd table that respect the condition where DestinedUserTypeID should be equal to UserTypeID),
Table 1

Thank you!
You can do it with a simple join linked to your table 1 and 2 and just insert into your table3
SELECT
u.id,
t.id,
from
table1 as u inner join
table2 as t on u.userTypeId = t.DestinedUserTypeID

update table2
set recordid=T1.ID
From Table1 T1
join Table2 T2 on T2.Group=T1.Group
This isn't distinct so I don't think it's right, but I can't figure it out.
where ?????
the problem is you have multiple Id per group , so you have to choose one :
update table2
set recordid= ( select top 1 T1.ID
From Table1 T1
join Table2 T2 on T2.Group=T1.Group
)
where recordid is null
I have to tables :
Table1
--------------------------------
ID VAL1 DATE1
--------------------------------
1 1 20/03/2015
2 null null
3 1 10/01/2015
4 0 12/02/2015
5 null null
Table2
--------------------------------
ID VAL2 DATE1
--------------------------------
1 N 02/06/2015
1 N 01/08/2015
2 null null
3 O 05/04/2016
3 O 02/02/2015
4 O 01/07/2015
5 O 03/02/2015
5 N 10/01/2014
5 O 12/04/2015
I want to update :
column VAL1 (of Table1) with '0', if VAL2 (of Table2) is equal to 'O'
column DATE1 (of Table1) with the earliest DATE2 (of Table2) for each ID (here my problem)
(This two tables are not so simple, it's just for illustration, they can be joined with the ID column).
Here my code :
UPDATE Table1 t1
SET t1.VAL1 = '0',
t1.DATE1 = (select min(t2.DATE2) --To take the first DATE for each ID where VAL2='O' (not working fine)
FROM Table2 t2, Table1 t1
WHERE trim(t2.ID) = trim(t1.ID)
AND VAL2='O')
WHERE EXISTS (SELECT NULL
FROM Table2 t2
WHERE trim(t2.ID) = trim(t1.ID)
AND t2.Table2 = 'O')
AND VAL1<>'0'; --(for doing the update only if VAL1 not already equal to 0)
The expected result is :
Table1
--------------------------------
ID VAL1 DATE1
--------------------------------
1 1 20/03/2015
2 null null
3 0 02/02/2015
4 0 01/07/2015
5 0 10/01/2014
The result I get is :
Table1
--------------------------------
ID VAL1 DATE1
--------------------------------
1 1 20/03/2015
2 null null
3 0 10/01/2014
4 0 10/01/2014
5 0 10/01/2014
My problem is that the DATE1 is always updated with the same date, regardless of the ID.
You shouldn't have a second reference to table1 in the first subquery; that is losing the correlation between the subquery and the outer query. If you run the subquery on its own it will always find the lowest date in table2 for any ID that has val2='O' in table1, which is 10/01/2014. (Except your sample data isn't consistent; that's actually N so won't be considered - your current and expected results don't match the data you showed, but you said it isn't real). Every row eligible to be updated runs that same subquery and gets that same value.
You need to maintain the correlation between the outer query and the subquery, so the subquery should use the outer table1 for its join, just like the second subquery already does:
UPDATE Table1 t1
SET t1.VAL1 = '0',
t1.DATE1 = (select min(t2.DATE2)
FROM Table2 t2
WHERE trim(t2.ID) = trim(t1.ID)
AND VAL2='O')
WHERE EXISTS (SELECT NULL
FROM Table2 t2
WHERE trim(t2.ID) = trim(t1.ID)
AND t2.Val2 = 'O')
AND VAL1<>'0';
You can use this UPDATE statement.
UPDATE TABLE1 T1
SET T1.VAL1 = '0',
T1.DATE1 = (SELECT MIN(T2.DATE2)
FROM TABLE2 T2
WHERE TRIM(T2.ID) = TRIM(T1.ID)
AND T2.VAL2='O')
WHERE T1.ID IN (SELECT T2.ID FROM TABLE2 T2 WHERE T2.VAL2='O')
Hope it will help you.
MYSQL Solution
Hope this MySql syntax also works with ORACLE.
The issue with the SQL is that it only consider the records with VAL2=='O' when calculating the earliest date. So the last record have the date as shown in table below. Record "5 N 10/01/2014" is not considered.
UPDATE Table1, (SELECT * FROM (SELECT * FROM table2 WHERE VAL2='O' ORDER BY ID, DATE1) X GROUP BY X.ID) T2
SET Table1.DATE1=T2.DATE1, Table1.VAL1=0
WHERE Table1.ID=T2.ID
..
Table1
--------------------------------
ID VAL1 DATE1
--------------------------------
1 1 20/03/2015
2 null null
3 0 02/02/2015
4 0 01/07/2015
5 0 **03/02/2015**
Tested on MySql 5.6.14
Lets say I have following tables:
Table1
ID Number
1 2
2 34
3 1 <---- Input (ID = 3) ==> (Number = 1)
4 6
5 5
*6* 7 <---- Want to find (Number = 6) because match in Table2
7 22
and Table2
Number Code Att1 Att2 Att3
1 1 1 <-----|
1 2 1 2 <-----|
6 2 f 2 |
6 3 4 3 2 |
2 4 6 |---Match
22 5 2 2 2 |
5 2 h 3 b |
7 1 1 <-----|
7 2 1 2 <-----|
7 h 5 r
So here is my Problem:
I want the IDs from Table1 that have all Code and Attributes from Table2 that a given (variable) input ID has. At the end I want to create a stored procedure/function that gives me all IDs meeting that condition.
As an Example:
Input-ID: 3. Would return ID 6 because Number 7 (mapped from ID 6 in Table1) has the rows Number 1 (mapped from ID 3 in Table1) has. It has more but that doesn't matter, its just important it has all rows the input one has.
(I can't find a solution to comparing a set of rows to another set of rows that is not known before.)
Thanks for any help!
Edit:
To make it more understandible, here what I want in words step-by-step.
Map input ID to Number in Table1
Get All Rows from Table2 having Number from Step 1
Get all Number that have the same (can have more) Rows as from Step 2
Get IDs for that Numbers (and return them)
Try something like this. Haven't tested it, but basically you inner join on all of the attributes that need to match. The HAVING clause is a crude check to make sure that it matched all the rows. Edit: Forgot to add the input ID WHERE clause.
SELECT t1b.ID FROM
Table1 t1a
INNER JOIN Table2 t2a ON t1a.Number = t2a.Number
INNER JOIN Table2 t2b ON t2a.Number <> t2b.Number AND t2a.Code = t2b.CODE AND t2a.Att1 = t2b.Att1 AND t2a.Att2 = t2b.Att2 AND t2a.Att3 = t2b.Att3
INNER JOIN Table1 t1b ON t1b.Number = t2b.Number
WHERE t1a.ID = 3
GROUP BY t1b.ID
HAVING COUNT(*) = (SELECT COUNT(*) FROM Table1 WHERE ID = t1a.ID)
select t11.ID as Id_To_Find,t12.ID as Id_Found
from Table1 t11
join (
select t21.Number as Found,t22.Number as ToFind from Table2 t21
left join Table2 t22 on t21.Code = t22.Code
and t21.Att1 = t22.Att1
and t21.Att2 = t22.Att2
and t21.Att3 = t22.Att3
and t21.Number <> t22.Number
group by t21.Number,t22.Number
having COUNT(*) = (select COUNT(*) from Table2 where Number = t22.Number))
as FindMatches
on t11.Number = FindMatches.ToFind
join Table1 t12 on t12.Number = FindMatches.Found
Kind of hard to understand what you're trying to acheive. As i understood from your example, you want to match the Number for the input ID in Table1 with any column (correct?) in Table2.
With input ID=3, the SELECT will return Number=7. In the IN (...)-condition, you can specify whichever columns in Table2 you want to match to Table1.Number.
DECLARE #Input INT = 3 -- Your input
SELECT DISTINCT t1.Number
FROM Table1 t
INNER JOIN Table2 t2 ON t.Number IN (t2.Number, t2.Code, t2.Att1, t2.Att2, t2.Att3)
INNER JOIN Table1 t1 ON t2.Number = t1.Number AND t.ID <> t1.ID
WHERE t.ID = #Input
I have a question on SQL join which involve multiple condition in second joined table. Below is the table details
Table 1
pId status keyVal
---- ------- ------
100 1 45
101 1 46
Table 2
pId mode modeVal
100 2 5
100 3 6
101 2 7
101 3 8
I have above two tables and I am trying to join based on below condition to get pId's
pId's which has keyVal = 45 and status = 1 joined with table2 which has mode = 2 and modeVal 5 and mode =3 and modeVal = 6
the result I am expecting is to return pid = 100
Can you please help me with a join query ?
One way is to use GROUP BY with HAVING to count that the number of rows found is 2, of which 2 are matching the condition;
WITH cte AS (SELECT DISTINCT * FROM Table2)
SELECT t1."pId"
FROM Table1 t1 JOIN cte t2 ON t1."pId" = t2."pId"
WHERE t1."status" = 1 AND t1."keyVal" = 45
GROUP BY t1."pId"
HAVING SUM(
CASE WHEN t2."mode"=2 AND t2."modeVal"=5 OR t2."mode"=3 AND t2."modeVal"=6
THEN 1 END) = 2 AND COUNT(*)=2
If the values in t2 are already distinct, you can just remove the cte and select directly from Table2.
An SQLfiddle to test with.
SELECT columns
FROM table1 a, table2 B
WHERE a.pid = B.pid
AND a.keyval = 45
AND a.status = 1
AND (
(B.mode = 2 AND B.modeval = 5)
OR
(B.mode = 3 AND B.modeval = 6)
)
Below query should work for you perfectly
select distinct table1.pid FROM table1 JOIN table2
on table1.pid = table2.pid
WHERE table2.modeValue IN (5,6) AND table2.mode IN (2,3) AND table1.keyVal=45 and table1.status=1;
