The following will result in a table scan, but it will do the job:
SELECT T1.Col1, COUNT(*) FROM Table1 T1
INNER JOIN Table2 T2 ON T1.Col1 LIKE '%' + T2.Col2 + '%'
Another alternative would be to create a full-text index on Table2.Col2. It all depends on how much data we're talking about and how often and how busy your server is when you run the query.

Sorry,
I wrote that a little quickly. Yes, I forgot the GROUP BY, but the main problem was I reversed the references on the join . Try this (I tested it this time  ):
SELECT T1.Col1, COUNT(*) FROM Table1 T1
INNER JOIN Table2 T2 ON T2.Col2 LIKE '%' + T1.Col1 + '%'
group by T1.Col1

and return me 0 rows
SELECT T1.Col, COUNT(*) FROM tbl1 T1
INNER JOIN tbl2 T2 ON T2.col LIKE '%' + T1.col + '%'
group by T1.Col
SELECT T1.Col, COUNT(*) FROM tbl1 T1
INNER JOIN tbl2 T2 ON T1.Col LIKE '%' + T2.Col + '%'
group by T1.Col
i also try this 2 sql sentences and is stil doesn't work

WHERE t1.col in (select t2.col from tbl2 t2))
From tbl1 t1
2)
select tbl1.col ,count(case when CHARINDEX(tbl1.col ,tbl2.col) > 0 then 1 else null end)
from tbl1,tbl2
group by tbl1.col

I'm running 2005 also. This script:
IF OBJECT_ID('Table1') IS NOT NULL
DROP TABLE Table1
IF OBJECT_ID('Table2') IS NOT NULL
DROP TABLE Table2
go
CREATE TABLE Table1(Col1 Varchar(15))
CREATE TABLE Table2(Col2 VARCHAR(100))
INSERT INTO Table1 VALUES('1000')
INSERT INTO Table1 VALUES('1001')
INSERT INTO Table1 VALUES('1002')
INSERT INTO Table2 VALUES('A1000A')
INSERT INTO Table2 VALUES('bbb1000bcd')
INSERT INTO Table2 VALUES('cdf1000frg')
INSERT INTO Table2 VALUES('A1001a')
INSERT INTO Table2 VALUES('bvc1001dcfe')
SELECT T1.Col1, COUNT(*) FROM Table1 T1
INNER JOIN Table2 T2 ON T2.Col2 LIKE '%' + T1.Col1 + '%'
GROUP BY T1.Col1
Gives me these results:
1000 3
1001 2
If this isn't working for you, you'll need to give me your schema and what the results are (or the error messages).

hi mark
You realy help in this Query
You are like Books Online
thanks again for your important help
and if it is nchar column type need to use ltrim rtrim function
SELECT T1.Col1, COUNT(*) FROM Table1 T1
INNER JOIN Table2 T2 ON ltrim(rtrim(T2.Col2)) LIKE '%' + ltrim(rtrim(T1.Col1)) + '%'
GROUP BY T1.Col1

Hi,
I am having some trouble with an sql statement and im just wondering if anyone could help me I have a ScoutingReport Table that stores player scouting info such as the matched, coached and playerId and I need a count of the amount of times a player has been scouted but if the same scout reports on the same match twice then I must only be counted once hers what I have started with any help would be appreciated.
Select Count(Distinct(MatchId))
From ScoutingReport
where ScoutedPersonId = 10002
group by MatchId
order by MatchId
Thanks in advance
Tim

Try:
select ScotedPersonId, count(distinct MatchId)
from ScotingReport
group by ScoutedPersonId
order by ScoutedPersonId
|
|
|
|
|
thats what i need so far but i should also have said that if a different scout reports on the same match then it should be counted as 2 reports any ideas
thanks for your reply

Which database are you using? You may be able to get away with:
select ScoutedPersonId,
count(distinct convert(varchar, MatchId) + '-' + convert(varchar, ScoutId))
from ScotingReport
group by ScoutedPersonId
order by ScoutedPersonId (which cheats a bit and turns the MatchId and ScoutId into a single string value that can be counted) or
select ScoutedPersonId, Sum(ScoutCount)
from (
select ScoutedPersonId, MatchId, count(distinct ScoutId) AS ScoutCount
from ScoutingReport
group by ScoutedPersonId, MatchId
) A
group by ScoutedPersonId
order by ScoutedPersonId (which uses an inline view).
Regards
Andy

I have a table where each row list's the product id and then 9 individual statistical percentage value relevant to that product. I need to create a final column to average all percentages into one overall score as well.
Any suggestions on how to do this?
The main select part of this code is below. Thanks in advance
SELECT ProductID, <br />
-- Calculate Speed percentage<br />
CONVERT(decimal(18, 2), @BestSpeed / (SELECT AVG(Finalised) FROM Leads WHERE Finalised IS NOT NULL AND ProductID = P.ProductID) * 100) As [Speed],<br />
--Actual speed value<br />
(SELECT AVG(Finalised) FROM Leads WHERE Finalised IS NOT NULL AND ProductID = P.ProductID) As [Actual Speed],<br />
-- Calculate APR value percentage<br />
CONVERT(decimal(18, 2), @BestAPR / (SELECT AVG(APR) FROM Leads WHERE APR IS NOT NULL AND ProductID = P.ProductID) * 100) As [APR],<br />
-- Actual APR value<br />
(SELECT AVG(APR) FROM Leads WHERE APR IS NOT NULL AND ProductID = P.ProductID) As [Actual APR],<br />
-- Calculate Broker Fee percentage<br />
CONVERT(decimal(18, 2), @BestBrokerFee / (SELECT AVG(BrokerFee) FROM Leads WHERE BrokerFee IS NOT NULL AND ProductID = P.ProductID) * 100) As [BrokerFee],<br />
-- Actual APR value<br />
(SELECT AVG(BrokerFee) FROM Leads WHERE BrokerFee IS NOT NULL AND ProductID = P.ProductID) As [Actual BrokerFee],
