Question

I have two tables in a SQL Server database: table1 and table2

table1:

 DATE        NAME    CREDIT
 1/1/2011    BALU      100 
 1/3/2011    BALU      200 

table2:

 DATE        NAME    DEBIT
 1/2/2011    BALU      100 
 1/3/2011    BALU       50 

I want to display the report in following format:

 DATE        NAME    CREDIT  DEBIT
 1/1/2011    BALU      100      0
 1/2/2011    BALU        0    100
 1/3/2011    BALU      200     50

My problem is that both tables have a date column.

How can I write the SELECT statement with a WHERE clause given that both tables have the same column named date?

I am still not positive about what you want, several details are missing. But based on experience working in similar queries I think this is what you might need (or close enough).

SELECT ISNULL(C.DATE, D.DATE) DATE, ISNULL(C.NAME, D.NAME) NAME, SUM(C.CREDIT) CREDIT, SUM(D.DEBIT) DEBIT
FROM TABLE_1 C
FULL JOIN TABLE2 D ON D.DATE=C.DATE AND D.NAME=C.NAME
WHERE ISNULL(C.DATE, D.DATE) BETWEEN @DATE1 AND @DATE2
GROUP BY C.DATE, D.DATE, C.NAME, D.NAME
