Convert Type (In Database)
(In-Database Processing)
Synopsis
Changes the data type of the selected columns.Description
Converts the data type of the chosen column. You can specify a default conversion that is applied on all columns that the attribute filter selects. You can also specify individual column data type conversions. The suggested data types are database-specific, and you can manually enter types that are not in the drop-down list. Note that for certain types, you may further specify the type, e.g. DECIMAL(8,2), NUMERIC(6,3), VARCHAR2(150). Data types in the output metadata are only available for these database-specific values, otherwise, the generic attribute_value is used.
