SQLDescribeParam Returns Errors If the Query Involves an Outer Join (328947)
The information in this article applies to:
- Microsoft ODBC Driver for SQL Server 2000 2000.81.7713.0
- Microsoft Data Access Components 2.7
- Microsoft Data Access Components 2.7 SP1
This article was previously published under Q328947 SYMPTOMS
If you use Microsoft ODBC Driver for SQL Server 2000, and the ODBC API SQLDesribeParam function is used to describe the parameter marker of a query that involves an outer join, you receive the following error messages:
[Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index
[Microsoft][ODBC SQL Server Driver]Syntax error or access violation
CAUSE
This problem is caused by a parsing error that occurs when the FROM clause of the query contains an "{oj ...}" escape sequence. For example, the following query returns these errors from the SQL Server Pubs database:
SELECT a.authors, b.titleauthors FROM {oj authors a LEFT OUTER JOIN titleauthor b ON a.au_id = b.au_id} WHERE a.au_lname = ?
