PL/pgSQL functions are considered as the better replacement for SQL functions in saving the client/server communication cost, this can result in a considerable performance increase. Similar to TSQL and PL/SQL, it adds some advanced features to SQL such as loops, variables, error and exception handling, etc. ![]() PL/PgSQL is a PostgreSQL-specific procedural language based on SQL. TSQL is also considered easier and simpler to understand while PL/SQL seems to be more complicated. The main difference between the TSQL and PL/SQL is the way they handle variables, stored procedures, and built-in functions. PL/SQL or Procedural Language/SQL is another extended form of SQL which is used by Oracle for their database. SQL is not Turing complete and is very limited in the scope of what it can do. ![]() These additions make T-SQL comply with the Turing completeness test, a test that determines the universality of a computing language. TSQL adds some advanced features to SQL to make it more powerful such as declared variables, transaction control, error and exception handling, string operations, date and time processing. TSQL was originally developed by Sybase & now is owned by Microsoft. TSQL, or T-SQL, shorts for Transaction-SQL, is an enhanced version of SQL which has with some extensions built on top of it. Then due to some level trademark issues, it’s renamed to SQL, though a lot of people still call it sequel today. SQL was developed by IBM in the early 1970s under the name SEQUEL. However, each database management system has its own extensions thus the syntax and some functionalities might be different. It’s used as the standard language across all relational database management systems. SQL is the query language used for communicating with data held in a relational database. ![]() PL/pgSQL is a procedural language used by PostgreSQL.PL/SQL is a proprietary procedural language with embedded SQL used by Oracle.TSQL is a proprietary procedural language used by Microsoft SQL Server.SQL (Structured Query Language) is a standard language used in managing data in almost all relational database management systems (RDBMS) such as PostgreSQL, MySQL, SQL Server, Oracle, DB2, Informix, etc.
