> Key: TEIID-68
> URL: https://issues.jboss.org/browse/TEIID-68
> Project: Teiid
> Issue Type: Bug
> Components: XML Connector
> Affects Versions: 9.x
> Reporter: Steven Hawkins
> Priority: Optional
>
> Defect Tracker #18728: If the where clause processed by the XML connectors has an equivalence expression containing two columns (where col1 = col2), the expression will be ignored. If the expression contains a column and a literal, it works properly. Thus a workaround is to use a scalar conversion function to convert the column to a literal. Something like substring(col1, 0) for string values or (col1 * 1) for numeric values.
