Column name

Specify the SQL name for the column in the Column name field. You can also specify a short name in the Short name field. If you do not specify a name, the system generates a name for you. If your column name is longer than 10 characters, a 10-character short column name is generated for you using the first 5 characters of the column name followed by a 5-digit unique number. If the column name is not longer than 10 characters, the short column name is the same as the column name. For an existing table, the short column name is shown.
