dataType (aggregate)

The dataType property in the Aggregate category specifies the data type of the aggregate fields.

This property is available only when the aggregate property is selected.

If fieldType is NON_DATABASE, the data type has to be specified. For other field types, the data type is determined from the database column type and cannot be modified.

For certain values of dataType for aggregate fields, other properties are enabled:
  • If dataType = DATETIME, you can set qual1 and qual fraction. For further information, see Using the DATETIME type in the Genero Business Development Language User Guide.
  • If dataType = DECIMAL, you can set precision and scale. For further information, see Using the DECIMAL type in the Genero Business Development Language User Guide.
  • If dataType = INTERVAL, you can set qual1, precision, and qual2. For further information, see Using the INTERVAL type in the Genero Business Development Language User Guide.

There is not an explicitly-named dataType attribute in Genero BDL. A widget's data type is defined within a form's ATTRIBUTES section. For related topics, search on ATTRIBUTES section in the Genero Business Development Language User Guide.
