TCL Full Form
What is the full form of TCL?
TCL stands for Transaction Control Language. The majority of database management and control TCL commands are used to maintain consistency.Additionally, it assists a user in keeping track of all the adjustments performed by the DML instructions to maintain its transactions. TCL allows the statements to be organised into logical transactions.
Several SQL statements are combined into a transaction, which affects the knowledge and data stored in the database management system.The database immediately records any transaction that is made (database). A user must give TCL instructions to permanently implement these adjustments or changes. A user can additionally control some changes made to the data in a table using DML statements by using the DDL command and DML command.
Apart from this, TCL Technology is a Chinese electronics company with its headquarters in Huizhou, Guangdong Province. Telephone Communication Limited was the initial abbreviation for TCL Technology. Among the things it designs, develops, produces, and distributes are consumer goods including televisions, mobile phones, air conditioners, washing machines, refrigerators, and small electrical appliances. In 2010, it was recognised as the 25th-largest consumer electronics manufacturer in the world. It surpassed Sony in 2019 to become the second-largest television manufacturer by market share.
TCL Commands
These are the TCL commands:
COMMIT
ROLLBACK
SAVEPOINT
Uses of TCL Commands
COMMIT: This command enables a user to permanently preserve a certain transaction into the database. The changes produced when using a DML command like DELETE, UPDATE, or INSERT are temporary until the current session is closed. In other words, if one doesn't permanently retain data, the alterations could be undone. We therefore utilise the COMMIT instruction to steer clear of it and be on the safe side. It designates these adjustments as lasting.The COMMIT command syntax is COMMIT.
ROLLBACK: The purpose of this command is to return the database to its fully committed state. If you want to jump to a save point in an ongoing transaction, you may also utilise it with the SAVEPOINT command. In essence, it assists a user in retrieving or recovering data to the most recent committed state/savepoint.
When using the UPDATE command to make a few small updates in the database, a user can discover that the changes are not necessary. Therefore, the user can use the ROLLBACK command to rollback the data to the most recently committed state or any specific savepoint if the inserted, updated, or deleted data is wrong for some reason. In other words, if the user didn't use the COMMIT command to commit the changes, you can undo them.The ROLLBACK command syntax is ROLLBACK TO savepoint name.
SAVEPOINT: This command makes it straightforward for a user to roll back to a certain point if necessary by momentarily maintaining a transaction. As a result, you can use the ROLLBACK command to go back to different data states in a table after using the SAVEPOINT function to identify them. SAVEPOINT savepoint name is the syntax for the command.
Advantages of TCL
It is utilised in SQL (Structured Query Language), which is highly interactive, portable, and compatible with numerous PC, server, and laptop apps.
Users can quickly access, edit, and save database changes.
The necessary coding is not particularly difficult. It is practical for even new users to use.
The instructions are practical and simple to remember.
Disadvantages of TCL
The ROLLBACK command is ineffective when a user commits using the COMMIT command.
One must create a savepoint in order to be able to go back in time; else, substantial content changes would be lost.
Finding savepoints may be difficult for beginners.
