For example: a column's default definition is "to_char(XXXX)"
In the column mapping view, a check option "expression" was added,
If this option is checked, the CMT will regard the text in default text box as a expression else CMT will regard the text as a value.
Exception happened when set default vaule.
It caused by thread count settings, not default values settings
