ALTER USER
ALTER USER
Syntax
6
Once the above statement is executed, the column will appear as a BIGINT column both
internally and to applications.
A statement such as this executed against a column that is not 32-bit will result in an error.
In this example, ALTER TABLE adds an ABL description to a table and changes the ABL default
data access index of the table:
ALTER TABLE pub.customer SET PRO_DESCRIPTION 'Sports 2000 Customers';
ALTER TABLE pub.customer SET PRO_DEFAULT_INDEX CustNumIdx;
In this example, ALTER TABLE RENAME INDEX is used to change an index named CustNum to
CustomerNumberIndex:
ALTER TABLE Customers RENAME INDEX CustNum to CustomerNumberIndex;
The ALTER TABLE statement enables you to change the names of tables or columns or to add
columns while your database is online servicing other requests. Other changes performed by
ALTER TABLE must occur offline.
Authorization
Must have the DBA privilege, ownership of the table, or all the specified privileges on the
table.

Notes • Used in conjunction with CREATE USER and DROP USER, the ALTER USER statement provides
a way to change a user password.
• The old_password specification must match the current password for username.
