             Summary: ODBC "Parse Statements" option can result in changes in LENGTH metadata for columns
                 Key: TEIID-4228
                 URL: https://issues.jboss.org/browse/TEIID-4228
             Project: Teiid
          Issue Type: Bug
         Environment: Connections through ODBC driver
            Reporter: Marc Shirley
            Assignee: Steven Hawkins


Connections through ODBC driver with the driver setting "Parse Statements" option enabled can result in incorrect length values being passed to the client.  In some cases (such as SQL Server linked server capabilities), this can result in the client throwing exceptions due to the expected LENGTH changing during the course of the query execution.

This may be limited to columns with precision set to 0, as the SQL Server linked server case was corrected when the precision was changed from 0 to 9 for the column specified in the error.
