Locks are held on SQL Server resources, such as rows read or modified during a transaction, to prevent concurrent use of resources by different transactions. For example, if an exclusive (X) lock is held on a row within a table by a transaction, no other transaction can modify that row until the lock is released.

Locking a data table prevents data and column properties from being added or edited. You can still assign row states, run analyses, and so on. To lock a data table, click the red triangle next to the table name in the table panel and select Lock Data Table.

The basic syntax used for LOCKING a table in SQL is as follows: LOCK [ TABLE ] [ ONLY ] table_name [ IN lock_mode MODE ] [ NOWAIT ]; The parameters used in the above-mentioned syntax are as follows: table_name: Name of the table on which you want to apply LOCK.

The LOCK TABLE statement prevents concurrent application processes from using or changing a table. The lock is released when the unit of work issuing the LOCK TABLE statement either commits or terminates.

Given below is the syntax of Oracle Lock table: LOCK TABLE table_name IN lock_mode MODE [WAIT | NOWAIT ];

It's not possible to manually lock a row in Oracle. You can manually lock an object,though. Exclusive lock is placed on the row automatically when performing DML operations to ensure that no other sessions could update the same row or any other DDL operations could drop that row- other sessions can read it any time.

Specify the name of the table or view to be locked. If you specify view , then Oracle Database locks the base tables of the view. If you specify the partition_extension_clause , then Oracle Database first acquires an implicit lock on the table.
