T-SQL focuses on the degree of control on how an application works whereas, the PL-SQL is a natural programming language that blends well with the SQL.The full form of T-SQL is Transact-SQL whereas, the full form of PL-SQL is Procedural Language SQL.
The basic difference between T-SQL and PL-SQL is that T-SQL is a Microsoft product whereas, PL-SQL is an Oracle product.With the help of PL-SQL, you can create applications, server pages that would display the information, obtained by the SQL statements in the code of PL-SQL. These features make PL-SQL t uring complete which means like T-SQL, PL-SQL is also universally accepted. Like procedural language, it also features error handling. PL-SQL being procedural extension allows declaring variables, constants, functions, loops, procedures, packages, etc. PL-SQL is a block structured language it executes the block of code at a time. As PL-SQL is an extension to SQL, that means the SQL statements are embedded in procedural language statements. PL-SQL is a Procedural extension to Structured Query Language Which was developed by Oracle Corporation in early 90’s for its own database management. Definition of PL-SQL (Procedural Language – SQL) T-SQL performs best when used with Microsoft SQL servers as it is a Microsoft proprietary. This kind of add-ons makes T-SQL turing complete, which means this computing language is universally accepted. T-SQL also features function for string operation, mathematical operations, date and time processing, error checking. T-SQL is entirely a database programming language which has variables, functions, data definition, data manipulation statements, loops conditional statements and procedures. Transact-SQL is a product Microsoft, and it is an extension to SQL.
