Sets the formatting of a field. The properties of qFieldAttributes and the formatting mechanism are described below. Formatting mechanismThe formatting mechanism depends on the type set in qType, as shown below: Information note
In case of inconsistencies between the type and the format pattern, the format pattern takes precedence over the type. Type is DATE, TIME, TIMESTAMP or INTERVALThe following applies:
Type is INTEGERThe following applies:
Type is REALThe following applies:
Type is FIXThe following applies:
Type is MONEYThe following applies:
Type is ASCIINo formatting, qFmt is ignored. |
