DOCUMENT:Q326817 30-JUL-2002 [sna] TITLE :FIX: "Reserved Error (-7743)" Error Message with ODBC for DB2 PRODUCT :Microsoft SNA Server PROD/VER:: OPER/SYS: KEYWORDS:kbhis2000 kbhis2000bug ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Host Integration Server 2000 ------------------------------------------------------------------------------- SYMPTOMS ======== When you try to select DB2 tables that contain fields that are specified as SMALLINT, you may receive the following error message: Reserved Error (-7743); there is no message for this error. This behavior occurs only if you are using the ODBC Driver for DB2 that comes with Host Integration Server 2000 (HIS). SNA Server 4.0 does not experience this problem. CAUSE ===== When an application calls the ODBC SQLGetData function, the ODBC Driver for DB2 incorrectly returns a 4-byte value for the data type SMALLINT. The SMALLINT data type should return a 2-byte value. RESOLUTION ========== Host Integration Server 2000 ---------------------------- A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Host Integration Server 2000 service pack that contains this fix. To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix.

STATUS ====== Microsoft has confirmed that this is a problem in Host Integration Server 2000. MORE INFORMATION ================ This error occurs when the underlying Jet engine tries to retrieve information about the indexes of the table by using SQLStatistics, and then later tries to retrieve the data in a field by using SQLGetData. A field definition may be the folowing: Name: Type Size: Smallint The following is the result of calling SQLGetdata in the ODBC Test application (ODBCTE32.EXE in the Microsoft ODBC Software Development Kit (SDK)): In: Statementhandle = 0x009D1BF0, ColumnNumber = 7, TargetType = SQL_C_DEFAULT=99, TargetValuePtr = 0x001552B0, BufferLength = 12, StrLen_or_IndPtr = 0x00172E88 Return: SQL_SUCCESS=0 Out:*TargetValuePtr = 0x03000000, *StrLen_or_IndPtr = 4 The Length of the SMALLINT data type is incorrectly returned as a 4-byte value; the value of Length should be only 2 bytes.
