A computer language called Transaction Control Language (TCL) is used to manage transactions in a database. TCL programs use a combination of Java and SQL syntax. Although they include additional features for influencing the behaviour of the database, such as encrypting records and examining the contents of files, they work similarly to Java programs in terms of how they are executed. TCL is a simple-to-use Java substitute for database development. TCL, or Transaction Control Language, is a programming language for creating computer code. It enables the development of business logic that may be used on the platform to support peer-to-peer transactions. This article will go over the syntax of the TCL language and give some examples of how to apply it to your work.

The History of TCL
A programming language called Transaction Control Language (TCL) enables programmers to create rules that specify how data is kept and accessed in a database. The Hyperledger Fabric platform uses Transaction Control Language (TCL) programming to create programs. This tutorial will help you get how to create a straightforward TCL program that, when executed, displays a greeting. The Hyperledger Fabric programming platform’s features are the foundation for this software development. If you attempt to run it on a Hyperledger Fabric test network environment, it will not function. After finishing, you can learn more about programming with Hyperledger Fabric, including creating network- and blockchain-interacting functions. Database transactions are created using the programming language known as Transaction Control Language (TCL). A series of actions carried out collectively constitute a transaction. A transaction is a name for this particular type of activity. The value of the database is changed to reflect the database’s modified state when an action is committed, which completes all of the activities in the transaction.
Example:
These are employed to control the adjustments that DML (Data Manipulation Language) statements make. Additionally, it enables the grouping of statements into logical transactions. Examples of TCL commands include commit, which is used to save that transaction into the database permanently. The commands Commit, Rollback, and Savepoint, are used in Transaction Control Language.
COMMIT: This instruction is used to store the data permanently.
ROLLBACK: Use the rollback command to retrieve or restore data to the most recent
SAVEPOINT: Save a point or decide to commit state.
Advantages of TCL
The dynamic programming language TCL is a high-level, general-purpose, interpreted language.
It was made to be incredibly straightforward but strong. Even programming constructs like the assignment of variables and the design of procedures are transformed by TCL into commands.
Disadvantages of TCL
TCL has a lot of benefits, but there are also certain drawbacks to the language that should be considered when building scripts. Using disciplined programming techniques can solve some of these issues, while extension packs, many of which are also publicly available, can solve others. About the implementation of the circuits editor GUI, this section lists many of the possible TCL problems.
