sql statement to add a new field to an existing table

To add new fields to an existing table, you can use SQL  ALTER TABLE statements. Following is the syntax for adding fields:

ALTER TABLE table_name
ADD column_name data_type;

sql copy code

in:

• table_name is the name of the table to add the field to.
• column_name is the name of the field to add.
• data_type is the data type of the field to add.

For example, if you want to  users add an  age integer field named to the table named, you can execute the following SQL statement:

ALTER TABLE users
ADD age INT;

sql copy code

Note that adding fields may cause data loss or restructure existing data, so it is best to back up your data before making any changes.
