FIX: Jet 4.0 Creates Incorrect CREATE TABLE Statements

Incorrect CREATE TABLE statements are created when Microsoft Jet database engine 4.0 exports tables through ODBC drivers that do not require identifier quote characters.

If an ODBC trace is generated, a you see a statement similar to the following:

Notice that the table name and all of the field names are missing, which causes failures in the backend database.

This can be reproduced with any product or technology that uses Jet 4.0, such as Access 2000 and DAO 3.6.

By default, Jet encloses table and field names in quote characters when constructing the SQL statement. An error in Jet's parsing logic is leaving out the table and field names when using an ODBC driver that does not require identifier quote characters.

To determine if a certain ODBC driver supports identifier quote characters, use the ODBC API SQLGetInfo with the type SQL_IDENTIFIER_QUOTE_CHAR. A blank is returned if the driver does not support this.

To resolve this problem, install Jet hotfix version 4.0.3515 or upgrade to the latest Jet 4.0 service pack.
