How do I clear all the data in a SQL Server table with a query? From SSMS, connect to the SQL Server database and use the TRUNCATE TABLE command to clear the data from the table.<\/p>\n\n\n\n
Note that the TRUNCATE command is different from the DELETE query in that all data is removed without any filter. The TRUNCATE command is therefore faster and recommended.<\/p>\n\n\n\n
This command deletes all the data stored in the table. Be careful, this command is irreversible. Remember to check your database backups to avoid losing data.<\/p>\n\n\n\n
Note that this action is irreversible.<\/mark><\/strong><\/p>\n\n\n\n Simply use a T-SQL query from SQL Server Management Studio<\/a><\/strong>, with the TRUNCATE TABLE command.<\/p>\n\n\n\n Note that the TRUNCATE query is different from the DELETE<\/a> command, especially in terms of performance. A DELETE FROM command scans all rows before deleting and allows you to filter the rows to be deleted.<\/p>\n\n\n\n The TRUNCATE command has more impact than a simple DELETE, especially because the truncate cannot be undone via the transaction log<\/a><\/strong>. The minimum right to execute a TRUNCATE command is ALTER. Because the DBMS considers this to be a modification of the table.<\/p>\n\n\n\n To delete the table completely, the data structure and the data must be deleted. To avoid generating error messages, then test the existence of the SQL Server table before deleting it<\/a><\/strong>.<\/p>\n\n\n\nTRUNCATE TABLE [dbo][SALES];\nGO\n<\/pre>\n\n\n\n
