Setting field name and type


Column name

Enter a name for the new field, or modify the name of the field being edited. Note that the name of a field must be unique among all the field names in the table.

 

The Data type tab defines the type of the field data.

 

Field Editor - Setting field name and type

 

Column type kind

This group allows you to select whether the field being create/edited is based on a standard (built-in) data type, an ANSI SQL data type, or a user-defined type.

 

RadioButton Oracle built-in datatype

Specifies that the field is based on a built-in Oracle data type.

 

Type

Here you can set the field type by selecting it from the drop-down list of built-in Oracle data types.

 

RadioButton Ansi SQL datatype

Specifies that the field is based upon a user-defined data type.

 

Type

Here you can set the field type by selecting it from the drop-down list of ANSI SQL data types.

Check this option to set default column value when it is explicitly set to NULL.

 

RadioButton User-defined data type

Specifies that the field is based upon a user-defined data type.

 

Schema

Use the drop-down list to select the schema containing the user-defined type.
