BUG# ODBCSS: 2816 (1.01.2920)



SYMPTOMS
The ODBC SQL Server driver returns an error with SQLSTATE S1093 when SQLSetParam is called for the 252nd time on a prepared statement with more than 252 parameter markers in it.

Because of this, users of Microsoft Access version 1.1 may see an error,

ODBC Call Failed

when they try and update an attached table with more than 125 columns.



STATUS
Microsoft has confirmed this to be a problem in ODBC SQL Server Driver version 1.01.2920. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



Steps to Reproduce Problem
For an ODBC application writer, do the following: //create a table with 127 columns CREATE TABLE lot_of_columns (col1 INT, col2 INT, ..., col127 INT)

//Prepare an update statement with 254 parameter markers SQLPrepare: UPDATE lot_of_columns SET col1 = ?,..., col127 = ? WHERE col1 = ?,..., col127 = ? SQLSetParam for each one of these parameters. The 252nd SQLSetParam returns SQL_ERROR:

SQLSTATE S1093, [Microsoft][ODBC SQL Server Driver]Invalid Parameter number

For users of Microsoft Access version 1.1, do the following:
 * 1) Attach to a SQL Server table with 126 columns or more.
 * 2) Open this table in datasheet view.
 * 3) Try to update a column in this datasheet.

The following error occurs:

ODBC - Call Failed. [Microsoft][ODBC SQL Server Driver]Invalid Parameter number

Additional query words: SQLSetParam S1093
