Delete all records from a table in MySQL?
To delete all the records from a table in MySQL, use the TRUNCATE command. Let us fir see the syntax −
TRUNCATE TABLE yourTableName.
The above syntax will delete all the records from a table. Let us create a table to understand the above syntax −
mysql> create table TruncateTableDemo −> ( −> BookId int −> , −> BookName varchar(200) −> ); Query OK, 0 rows affected (0.54 sec)
Inserting records in the table with the help of insert command. The query to insert records in the table are as follows −
mysql> insert into TruncateTableDemo values(1001,'C in Dept'); Query OK, 1 row affected (0.18 sec) mysql> insert into TruncateTableDemo values(1002,'The C++ Programming'); Query OK, 1 row affected (0.22 sec) mysql> insert into TruncateTableDemo values(1003,'Let us C'); Query OK, 1 row affected (0.16 sec)
Now you can display all the records from the table with the help of a select statement. The query is as follows −
mysql> select *from TruncateTableDemo;
The following is the output −
+--------+---------------------+ | BookId | BookName | +--------+---------------------+ | 1001 | C in Dept | | 1002 | The C++ Programming | | 1003 | Let us C | +--------+---------------------+ 3 rows in set (0.00 sec)
Implement the above syntax to delete all the records from the table. The query is as follows −
mysql> truncate table TruncateTableDemo; Query OK, 0 rows affected (0.93 sec)
Now you can check all records have been deleted from the table or not.
The following is the query −
mysql> select *from TruncateTableDemo; Empty set (0.00 sec)
