SQL ALTER TABLE Statement Example 3 - Drop a column. The command to be used is ALTER TABLE table_name ALTER COLUMN column_name SET DATA TYPE VARCHAR(24); Here I assumed the data type as VARCHAR. And hope I am just a section of allowing you to get a greater product. If the alterations to a table cannot be performed using the DB2 ALTER command, you can use the Alter Table Option to automatically invoke RC/Alter to perform a drop and recreation of the table with the changes. Why do you want to delete records from DB2 tables using JCL. A single Impala query reads both the old and new data files, containing different numbers of columns.
