T-SQL is an extension of SQL developed by Microsoft for use with SQL Server. It includes additional features and functionalities beyond standard SQL. Example: SELECT * FROM Employees WHERE Department = 'IT' ORDER BY LastName;
T-SQL supports additional syntax and functionalities not available in standard SQL. T-SQL includes features like error handling, transactions, and stored procedures. Example: BEGIN TRANSACTION; INSERT INTO Orders VALUES (1001, 'Product A', 50); COMMIT TRANSACTION;
T-SQL offers advanced functionalities for working with SQL Server databases. It includes features like table variables, temporary tables, and user-defined functions. Example: DECLARE @TotalSales MONEY; SET @TotalSales = (SELECT SUM(Quantity * Price) FROM Sales);
SQL is a standard language supported by various database management systems (DBMS) like MySQL, PostgreSQL, and Oracle. T-SQL is specific to Microsoft SQL Server and is not fully compatible with other database platforms. Example: SQL queries written for MySQL may not work directly in SQL Server without modification.
