SQL vs. PL/SQL vs. T-SQL
SQL is a standard query language of the database.
Where the PL/ SQL stands for “Procedural Language extensions SQL.” It is used in the Oracle database and the extension of Structured Query Language (SQL). Whereas, T-SQL stands for “Transact-SQL.,” which is the extension of Structured Query Language (SQL) used in Microsoft.
Difference between SQL and T-SQL
| SQL | T-SQL |
|---|---|
| SQL is a type of Non-procedural language. | T-SQL is a procedural language of SQL and the subpart of SQL. |
| It is an open-source standard. | T-SQL is a proprietary standard. |
| Some DML and DDL commands are provided in SQL. | T-SQL provides unique features that are absent in SQL like, exception, transaction control, and error handling. |
| In SQL, Single query is transferred after the completion of others. | All commands are transferred to the server in T-SQL. |
| It is used for manipulating data when a large amount of information has stored. | It has many features of SQL, like the procedural elements and local variables. |
| There are many commands; many of them are INSERT, SELECT, UPDATE, DELETE, CREATE, and DROP. | It includes some functions of the converted date (). And other tasks are not the part of regular SQL. |
Difference between SQL and PL/SQL
| SQL | PL/SQL |
|---|---|
| SQL is a single query that performs the DML (Data manipulation language) and DDL (Data Definition Language) operations easily. | PL/SQL is the block of codes that are used to write the whole program function. |
| SQL is a declarative database. | PL/SQL is a procedural language that defines how things will execute. |
| A single statement is executed at a time in Structure Query Language. | A whole block is executed at a time in the PL/SQL. |
| Structure Query Language is used to manipulate the data. | PL/SQL creates the applications. |
| It interacts with the database server. | It cannot interact with the database server. |
| SQL cannot contain the code of PL/SQL. | PL/SQL is the extension of SQL, so it contains SQL inside it. |
Difference between T-SQL and PL-SQL
| SQL | PL/SQL |
|---|---|
| It is a Microsoft product. | Oracle has developed PL-SQL. |
| T-SQL generates a good control on programmer. | It is a natural programming language which blends the SQL. |
| T-SQL performs the best with the Microsoft SQL Server. | PL-SQL performs well with the Oracle database server. |
| It is easy to understand. | It is hard to understand. |
| It allows us to insert some rows into the table and uses the BULK INSERT statement. | PL/SQL supports the OOPs concepts like data encapsulation, information hiding, and function overloading. |
| In T-SQL, the SELECT INTO statement is used mostly. | In PL/SQL, the INSERT INTO statement is used. |
| NOT EXISTS clause is used with the SELECT statement here. | A MINUS (-) operator is used in the SELECT statement. |
Difference between SQL and T-SQL in points
SQL and T-SQL are the two sides of one coin which name is Microsoft SQL Server.
1. SQL and TSQL as a database language:
SQL stands for Structured Query language, which is used to execute a single query at a time with the insert/update/delete and select statement. Users cannot be able to perform many statements at the same time.
T-SQL is used to work with different transactional activities into SQL database. The user uses many programming techniques when utilizing the T-SQL.
2. Usages:
The SQL statements are used to create web pages, analytical reports, and screens. The SQL statements are used for generating and connecting the database in the applications. If the user wants to update the application, then sql statement generates the support team.
T-SQL is a transactional sql which is used to perform the back-end transactions of the application to use techniques of programming language. T-SQL is used to add the business logic in the application and used to build the application logic.
3. Standards of SQL and T-SQL:
SQL is ANSI/ISO Standard database. The Server implementation of SQL Server is the language called Transact-SQL.
4. Development companies:
IBM has developed SQL. TSQL is the implementation of the SQL server. Microsoft has developed it.
TSQL is used to writing the procedure, and many advanced concepts of databases are written in it.
5. SQL and T-SQL as Data or Program Oriented:
SQL is a Data-Oriented Language used to analyze the data for simple queries. It uses insert, update, and delete command.
T-SQL is a transactional language that is used to create applications like; we add business logic in the request.
6. SQL and T-SQL Objects:
SQL is used to write the DDL (Data Definition Language) statements as the DML (Data Manipulation Language) statements.
T-SQL is mainly used to write views, procedures, triggers, and functions. And it is called T-SQL objects.
7. Instructions of databases:
The sql statement executes only one statement at a time, but the T-SQL statements have a set of SQL statements and it executes one by one.
8. Embedding both the SQL and T-SQL
We can integrate the SQL into the T-SQL but we cannot insert the T-SQL code in the SQL.
