FACT(s) (Environment):
Memory-mapped procedure library
There are SQL statements in procedures that are included in the memory mapped procedure library.
Progress 9.1D
All Supported Operating Systems
CAUSE:
Bug# OE00100519
CAUSE:
When using NO-ERROR on a SQL-89 statement within a 4GL procedure in 9.1D, the 4GL interpreter has to flag the SQL statement as NO-ERROR on its in-memory copy of the procedure. If the procedure is in a memory-mapped library, this "in-memory" copy is read-only, which causes the access violation.
FIX:
There are two solutions for this issue.
1. Don't use NO-ERROR when calling procedures containing SQL statements in a
memory-mapped pl.
2. Don't use SQL statements in procedures within a memory-mapped pl. Use 4GL statements instead.
