What steps will reproduce the problem? 1. Using Firebird SQL Server, create a table with a column of datatype DECIMAL(9,5) 2. The maximum allowed value in a such a column is 21474.83647, or (2^31-1)/(10^5). Now, attempt to INSERT a value larger than the maximum into the column

What is the expected output? What do you see instead? I expect the error:

SQL Message : -802

Arithmetic overflow or division by zero has occurred.

But instead, pyodbc inserts the value -21474.8365

What version of the product are you using? On what operating system? Python 2.7.3 (32 bit) pyodbc-3.0.6-py2.7 Firebird SQL Server 1.5.6.5026 (32 bit) Firebird ODBC Driver 2.0.1.152 (32 bit) Windows 7 Professional x64

Please provide any additional information below. Attached is a test script illustrating the problem. (pyodbc also can't seem to SELECT the value -21474.8365 properly, but maybe that is a separate issue?)
