[CODE]
CASE field_val
WHEN 'M5' THEN EXEC ( @query)
ELSE THEN print ''
END

[/CODE]

I have a SP , and i state a query .. but i only
want this query to be executed based on the value
of field_val , otherwise i print a blank ..
but when i check the syntax (ms sql server 2000)
i get "invalid syntax near CASE ..

Condition execution using CASE is not allowed in SQL Server.

Why don't you go for straight forward IF..ELSE?

Yes CASE is allowed in query but dynamic execution of other query using EXEC with CASE is not allowed.

ok so i should have something like :
[CODE]
IF field_val = 'M5'
THEN EXEC (@Query)
ELSE
PRINT ''

[/CODE]

No.

If Exists(select * from table where field_val = 'M5')
EXEC(@query)
Else
print ''
