Delete Oracle Table Data: SQL Guide

To delete table field data, please follow the steps below:

1. You can use the DELETE statement to remove data from table fields. For example, to delete specific field data from a table, you can use the following syntax:

DELETE FROM table_name WHERE condition;

In this statement, table_name is the name of the table from which data will be deleted, and condition is an optional criteria used to specify the specific data rows to be deleted. If no condition is provided, all data in the table will be deleted.

1. Use the TRUNCATE TABLE statement to remove data from a table column. This statement is used to delete all data in a table while maintaining the table structure. For example, to delete all data from a table, you can use the following syntax:

TRUNCATE TABLE table_name;

In this statement, table_name is the name of the table from which data will be deleted.

Please note that if you want to delete a table field itself (and not the data in the table), you should use the ALTER TABLE statement. For example, to delete a specific field from a table, you can use the following syntax:

ALTER TABLE table_name DROP COLUMN column_name;

In this statement, table_name refers to the name of the table from which a field is to be deleted, and column_name is the name of the field to be deleted.

Please remember to backup your data before performing any deletion operations to prevent accidental loss.
