FIX: Negative 0 (zero) Causes ODBC SQL Server Driver Error

If a SQL Server query returns a negative zero, and the client application binds the results as a SQL_C_DOUBLE, the following error is reported to the client:

SQL Server is returning a negative zero, and the SQL Server driver is reporting this as an error. To reproduce the error run the following query: When you fetch the resulting column from this query you receive the error. In a more complex scenario the following query also causes the error:

Either bind the column as a SQL_C_CHAR or SQL_C_LONG to avoid the error. You can also check that the resulting data does not contain a negative zero.

Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server 7.0.
