SYMPTOMS
When you try to select DB2 tables that contain fields that are specified as SMALLINT, you may receive the following error message:
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
To resolve this problem, obtain the latest service pack for Host Integration Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in Host Integration Server 2000. This problem was first corrected in Host Integration Server 2000 Service Pack 1.
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 following:
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.
