While testing some queries that are written on teiid 8.11.3 I get mostly this error:
TEIID31172 Could not resolve expressions being compared to a common type excluding character conversions e.g. pc.RizivCode = 211260 with pc.RizivCode a string.
Changing 211260 to '211260' resolves the issue. Teiid 8.11.3 did an autoconversion for this situation. Can this be enabled again?
