Setting Column Labels
Columns in the result table normally have the same name as the corresponding columns in the source table.
By using an
ASclause after the column name in the
SELECTstatement, the column in the result table can be given an alternative name.
ASclauses can be used for as many columns as required. A label may be up to 128 characters long, and follows the same syntax rules as column names, see the Mimer SQL Reference Manual, SQL Identifiers.
For example:SELECT format AS format_name, category_id FROM formats;
Labels are particularly useful in queries that retrieve computed values, where the result table column is otherwise unnamed, see Retrieving Computed Values.
