C++ program...
SELECT LastName from Employees WHERE LastName LIKE ?
In the C++ program, I use the SQLBindParameter() to
associate to the ?. The SQLBindParameter() variable used
contains 'A%' (without the single quote).
This is a very simple statement, but constantly returns
no data.
I run this exact statement within a MS Access database
connection, and it returns 4 records. The MS Access wild
card is also 'A%'. I think there is a bug in the SQL
Server ODBC, but I cannot confirm this.
Using the SQL Trace doesn't tell me the translations
being performed within the ODBC driver to confirm a bug.
Help...please...
Regards,
AngeloHi Angelo,
The SQL Trace (you are using SQL 7 ?) will tell you the command the SQL
Servers sees. What does that look like?
Also have you tried 'A*' or have you tired
SELECT LastName from Employees WHERE LastName LIKE '?'
Just some ideas, I hope you fix the issue.
I hope this helps

I'm using SQL 8. I will try the TRACE again. I've tried
your other suggestions but still get the same results.

<http://www.spammarshall.com>|||I'm probably saying something pretty dumb right now.. but how are you using
ODBC?
Why can you not simply (assuming you're using MS Visual C++ with MFC) do:
CString sql;
sql.Format(_T("SELECT LastName from Employees WHERE LastName LIKE %s",
_T("A%%");
rs.Open(sql...)
Or something like that.. ?

I am using the latest SQL Server 8 with Visual C/C++ 6.00.
Everything has the latest software patches including the
DB and compilers.
