Using DELETE in an Import Task
In the following example, an input data source contains a series of one-field, four-byte records. Each record contains the value (EmpNum) of the primary index column (EmpNo) of a row to be deleted from the Employee table. The example assumes that the Employee table is in the current default database.
.LAYOUT Layoutname; .FIELD EmpNum 1 INTEGER; .DML LABEL DMLlabelname; DELETE FROM Employee WHERE EmpNo = :EmpNum;
