I have two tables in SQL Server that looks as follows,
Table 1:
Store Type
100 A
101 B
102 B
103 B
104 C
105 C
106 A
107 A
108 D
109 D
110 C
111 B
112 D
and table 2:
Store Units
100 5
101 3
102 10
103 6
104 6
105 8
I want to combine the two tables in a query with a relationship link between the Store column of the two tables. The problem i have is that if i create a query between the two then the stores from 106 to 112 does not appear in the table. The query looks as follows,
SELECT dbo.Table1.Store,
dbo.Table1.Type,
dbo.Table2.Units
FROM Table1 INNER JOIN Table2
ON dbo.Table1.Store=dbo.Table2.Store
What should i do to include the stores that does not appear in Table2 (106-112) but in Table1 and make there Units = 0, such that the query table look as follows,
Store Type Units
100 A 5
101 B 3
102 B 10
103 B 6
104 C 6
105 C 8
106 A 0
107 A 0
108 D 0
109 D 0
110 C 0
111 B 0
112 D 0
You want a left outer join instead of an inner join:
SELECT t1.Store, t1.Type, COALESCE(t1.Units, 0) as Units
FROM Table1 t1 LEFT JOIN
Table2 t2
ON t1.Store = t2.Store;
I also introduced table aliases for your query to make it more readable. Note the use of coalesce() so you get 0 for Units instead of NULL.
SELECT dbo.Table1.Store, dbo.Table1.Type, coalesce(dbo.Table2.Units, 0) As Units
FROM Table1
LEFT JOIN Table2 ON dbo.Table1.Store=dbo.Table2.Store

I would like to get the representation of one record based on the primary key value from multiple tables. As shown below, each table can have multiple values based on this primary key value.

The important thing here is that in the result value, SCHOOL only shows that AUT is 'A'.
I would appreciate it if you let me know your query.
It looks, from your desired results, you just need to use row_number in combination with a conditional aggregate. Your sample data seems a little inadequate, I can't see any requirement for table1 at all.
Try the following:
with t as (
select t2.id,t2.school,t3.tc, Row_Number() over(partition by t2.id order by t3.tc) col
from t2 join t3 on t2.id=t3.id
where aut='A'
)
select id,school,
max(case when col=1 then tc end) TC1,
max(case when col=2 then tc end) TC2,
max(case when col=3 then tc end) TC3
from t
group by id, school
Example SQL Fiddle
SELECT
T1.ID, T2.SCHOOL,
GROUP_CONCAT(T3.TC),
GROUP_CONCAT(T2.AUT)
FROM
T1
LEFT OUTER JOIN
T2 ON T1.ID = T2.ID
LEFT OUTER JOIN
T3 ON T1.ID = T3.ID
GROUP BY
T1.ID, T2.SCHOOL
WHERE
T2.AUT = ‘A’
ORDER BY
T1.ID ASC
Notice that GROUP_CONCAT concatenates the values in the row.
EDIT: oh my, haven't seen that it's a SQL Server question!
Just replace GROUP_CONCAT with STRING_AGG if you’re using SQL Server 2017 or newer.
I need to compare and identify all IDs that have a mismatch in the codes between the categories, upper and lower case are only examples and I cannot base the join on the category field as they are different.
e.g: ID 1 - cat A, a have the same code but ID 3, cat E and e have a mismatch, same with ID#4.
Edit: sorry - after posting the question, and looking at the answers I have realized that my question was not conveying what I am looking for, and I have mocked up data incorrectly. The Category doesn't always have the same name as uppercase/lowercase letters, this was only meant to be an example.
T1
ID Cat Code
1 A 100
1 a 100
1 B 101
1 b 101
2 C 102
2 D 103
2 d 103
3 E 104
3 e 107
3 F 105
3 g 106
4 I 109
4 i 110
5 ABC 111
5 XYZ 112
5 KLM 123
6 PQR 113
6 STU 113
Desired output:
ID Cat Code
3 E 104
3 e 107
4 I 109
4 i 110
5 ABC 111
5 XYZ 112
5 KLM 123
This answers the original version of the question.
Use exists:
select t1.*
from t1
where exists (select 1
from t1 tt1
where tt1.id = t1.id and
upper(tt1.cat) = upper(t1.cat) and
tt1.cat <> t1.cat and
tt1.code <> t1.code
);
Oracle is case-sensitive by default.
You can use a self join like below to handle this issue:
select t1.*
from tablename t1
inner join tablename t2 on t2.ID = t1.ID and upper(t1.Cat) = upper(t2.Cat)
where t1.Code <> t2.Code
I have 2 tables:
Table1 - Criteria
Office_ID Bus_Stream Bus_Criteria Crit_Value
1 ABC 0 20
1 ABC 1 21
1 ABC 2 7
2 ABC 0 15
2 ABC 1 12
2 ABC 2 21
3 XYZ 1 17
3 XYZ 2 3
Table2 - Limit
Bus_Stream GroupID TypeID SubgroupID Bus_Limit
ABC 20 21 7 50
ABC 15 12 21 100
XYZ 99 17 3 120
I need to create a join that allows me to pull back:
Result
Bus_Stream Office_ID GroupID TypeID SubgroupID Bus_Limit
ABC 1 20 21 7 50
ABC 2 15 12 21 100
XYZ 3 (null) 17 3 120
Essentially, I need to join Table1.Crit_Value based on the following:
Table1.Bus_Criteria Table2
0 GroupID
1 TypeID
2 SubGroupID
with the added complication that if one or two of the 0/1/2 values from Bus_Criteria is missing, the joins will still occur on the remaining criteria.
I have tried a number of combinations of AND/OR on the join to no avail.
Any ideas folks?
This may be what you're after.. use a case statement on the join.
The problem here is your data in t2 isn't normalized, you could also unpivot the 3 data columns in t2 so the join is more natural.
SELECT T2.Bus_Stream, T1.Office_ID, T2.GroupID, T2.TypeID, T2.SubGroupId, T2.bus_Limit
FROM T1
INNER JOIN T2
on T1.Bus_Stream = T2.Bus_Stream
and T1.Crit_value = case when T1.Bus_Critiera = 0 then T2.GroupID
when T1.Bus_Critiera = 1 then T2.TypeID
when T1.Bus_Critiera = 2 then T2.SubGroupID
end
Did you try something like this?
SELECT
t1.*, t2.*
FROM Table1 t1
INNER JOIN Table2 t2 ON
t1.Bus_Stream = t2.Bus_Stream AND
CASE
WHEN t1.Bus_Criteria = 0
THEN t2.GroupID = t1.Crit_Value
WHEN t1.Bus_Criteria = 1
THEN t2.TypeID = t1.Crit_Value
ELSE
t2.SubGroupID = t1.Crit_Value
END

To get the required output if i do left outer join between components and empPayrollDetail I get null in EmployeeID and MasterID and amount Columns. How to modify left join to get the required output
You need to do a CROSS JOIN on Components and empPayrollMaster to generate first all combination of employees and components. Then, do a LEFT JOIN on empPayrollDetail to achieve the result, using ISNULL(amount, 0) for NULL amounts.
SQL Fiddle
SELECT
epm.EmployeeID,
epm.MasterID,
c.ComponentID,
amount = ISNULL(epd.amount, 0)
FROM empPayrollMaster epm
CROSS JOIN Components c
LEFT JOIN empPayrollDetail epd
ON epd.MasterID = epm.MasterID
AND epd.ComponentID = c.ComponentID
Try this
select empPayrollMaster.EmployeeID,empPayrollMaster.MasterID,
Components.componentid,isnull(empPayrollDetail.amount,0)
from empPayrollMaster
left join Components
on empPayrollMaster.EmployeeID is not null
left join empPayrollDetail
on empPayrollDetail.MasterID = empPayrollMaster.MasterID
and empPayrollDetail.ComponentID = Components.componentid
Try this way
select c.EmployeeID,d.MasterID,c.ComponentID,isnull(d.amount,0) as amount from (
select * from Components a
Cross join empPayrollMaster b) c
left outer join empPayrollDetail d on d.componentid =c.componentid
As you want the component amount for each employee in the master table you should use a insull(payrole_detail.amount,0) or, as #Turophile pointed out, the SQL standard function coalesce(payrole_detail.amount,0) for the amounts column.
SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
INNER JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;

You can use the not in operator:
SELECT *
FROM table1
WHERE providerid NOT IN (SELECT providerid FROM table2)
Multiple versions: fist with NOT IN
SELECT table1.*
FROM table1
WHERE table1.providerId NOT IN ( SELECT table2.providerId FROM table2 )
Second with NOT EXISTS:
SELECT table1.*
FROM table1
WHERE NOT EXISTS ( SELECT 1
FROM table2
WHERE table1.providerId = table2.providerId )
This next one is a bit strange: we do a LEFT JOIN and we check that the second table hasn't matched:
SELECT table1.*
FROM table1
LEFT JOIN table2
ON table1.providerId = table2.providerId
WHERE table2.providerId IS NULL
Which of the three versions above performs better depends (mostly) on the cardinality of the two tables.
Sorry, I misunderstood the question. This should do the trick.
The first part of the query selects all the pairs userId - providerId. The second part removes all the ones present in table1.
SELECT U.userId, P.providerId
FROM (SELECT DISTINCT table1.userId FROM table1) U, table2 P
MINUS
SELECT table1.* FROM table1
EDIT
this is the table structure i have used to get the output

13 rows selected.
SELECT a.userid, b.providerid FROM table1 a, table2 b
WHERE a.providerid IS NOT NULL
MINUS
SELECT userid, providerid FROM table1 a
WHERE a.providerid IS NOT NULL;
The query bring the desired output...
Thanks all for ur efforts.
