SYMPTOMS

Under the following conditions, an application written with the DB-Library API using cursors may cause syntax errors as well as the cursor not being created:

The query sent with the dbcursoropen function is a stored procedure.
The function dbrpcparam is used to pass parameters to the stored procedure.
The type of one of the parameters is binary or varbinary.

Here are examples of the errors received:

Msg=170 Severity=15 State=1
Line 1: Incorrect syntax near '??'.

Msg=16945 Severity=16 State=1
The cursor was not declared.

Passing the binary datatype as a character type and converting it in the stored procedure works if the data does not contain any extended characters that could be translated through ANSI to OEM settings.
