To add a column after a certain field in DB2, you can use the ALTER TABLE statement. Here are some simple steps to add a column after a certain field in DB2:

  1. First, use the following ALTER TABLE statement to add a new field to the table:
ALTER TABLE 表名 ADD 列名 数据类型;

For example, to add a field named “bonus” after the “salary” field in a table called “employees,” you can use the following statement:

ALTER TABLE employees ADD bonus DECIMAL;
  1. If you need to specify the position of a new field, you can use the AFTER keyword. For example, to add the “bonus” field after the “salary” field, you can use the following statement:
ALTER TABLE employees ADD bonus DECIMAL AFTER salary;
  1. Finally, submit the changes and save the table structure.
COMMIT;

This will allow you to add a field after a certain field in DB2. Make sure to backup your data before executing the ALTER TABLE statement in case of any unexpected issues.
