o SQL/MX MXCMP (T1050)
Solution 10-050710-9594
MXCMP fails with an assertion error at #ConstValue::pushDownType.
This problem could occur when:
- CQD INFER_CHARSET should be set to 'TRUE'.
- Table should be range partitioned on a character column.
- Plan should have an esp_exchange node.
Recovery
Use the workaround and re-compile the query.
Workaround
Specify CONTROL QUERY DEFAULT INFER_CHARSET 'FALSE'.
o SQL/MX MXCMP (T1050)
Solution 10-050817-0660
Query compilation fails with error 2105 when using a Control query
shape with pack nodes in MXCI.
Recovery
None.
Workaround
None. Pack nodes have to be used with rowsets. The feature
described above is not supported by MXCI. Hence MXCI reports
an error.
