You can create an index on a table using the CREATE INDEX statement. The syntax is as follows:

CREATE INDEX index_name
ON table_name (column_name);

2. Using the ALTER TABLE statement: The ALTER TABLE statement can be used to create an index on an existing table. The syntax is as follows:

ALTER TABLE table_name
ADD INDEX index_name (column_name);

Create an index in using DB2 Control Center: DB2 Control Center is a graphical tool that allows you to create indexes. Within the Control Center, you can select the table and column for which you want to create an index and specify a name for the index.

Using the db2look tool in the DB2 command line allows for generating DDL statements for tables. Subsequently, manually modifying the index section of the DDL statements and executing them will facilitate the creation of indexes.

5. Use the command-line tool in the DB2 command line window: In the DB2 command line window, you can create an index using the db2 command. The syntax is as follows:

db2 "CREATE INDEX index_name
