TRUNCATE TABLE
The TRUNCATE TABLE statement deletes all rows in a table.
General format
EXEC SQL [ AT Database ]
 
  TRUNCATE TABLE Table-Name [ Options ]
 
END-EXEC
Syntax rules
1. Options is passed to the driver without further checks. Refer to the database documentation for detailed syntax. Syntax errors, if any, are returned at runtime.
2. Table-Name is a User-defined word, as defined in the Definitions section of the Preface of this document.
General rules
1. Database identifies the active connection that will execute the query and must be previously defined using a Format 4 DECLARE statement. By default, when the AT clause is used, the active connection is switched to the connection identified by Database and all the next statements will work on that connection; under the -csora option, instead, the connection is switched only for the current statement.
Examples
Empty the table log
exec sql
     truncate table log
end-exec
