Hello,
QCM and QCM8 tables are used when you make modifications to a table and the table contains data. Then the procedure is as follows:
- rename the TABLE to QCMTABLE
- create TABLE anew with the new structure
- insert the data from QCMTABLE into TABLE
- if this was successful drop QCMTABLE
If there is a QCMTABLE left, this means a modifications once fails and the QCM table might contain data !! You should not drop them before you checked if the data they contain is in the original table or not.
