parameter query

[John Jayaseelan]

Hi,

The following parameter query resulted the error below. Is the following
syntax correct?

select * from branch where branch_code = ?
[Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error
Thanks

I asked same question. ;-)

You can't use parameters with a view. If you have MSSQL2000, then you could use a table-valued function:

create function dbo.GetProducts (@ProductID int)
returns table
as
return (select ProductID, NameOfProduct from dbo.Products where ProductID < @ProductID)

select * from dbo.GetProducts(5)

Otherwise, you can use a stored procedure.

Depends on which context you issued it in. It is not legal T-SQL. If you
run this from ISQL, which uses DB-Library that does not intercept the
SQL string, you get:

Msg 170, Level 15, State 1, Server KES-METS-, Line 1
Line 1: Incorrect syntax near '?'.

But if you run it from Query Analyzer, you get a more puzzling mesage:
[Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error

Note here that it does not say [SQL Server]. So this message comes from
the ODBC driver, because in the ODBC syntax, the ? is a special token
for a parameter holder. I don't the ODBC syntax well, so I cannot say
whether you can actually use this syntax successfully from QA. Normally,
you use this syntax when you pass SQL statements from application code.
