Delete all the records from a MySQL table?
To delete all the records from a MySQL table, you can use the TRUNCATE statement.
The syntax is as follows −
TRUNCATE TABLE yourTableName;
The above syntax deletes all the records from the table. To understand the above syntax, let us create a table. The following is the query to create a table −
mysql> create table DeleteAllFromTable −> ( −> PersonId int, −> PersonName varchar(200) −> ); Query OK, 0 rows affected (0.67 sec)
Insert some records in the table with the help of insert command.
The query is as follows −
mysql> insert into DeleteAllFromTable values(100,'Johnson'); Query OK, 1 row affected (0.10 sec) mysql> insert into DeleteAllFromTable values(101,'John'); Query OK, 1 row affected (0.22 sec) mysql> insert into DeleteAllFromTable values(102,'Carol'); Query OK, 1 row affected (0.47 sec) mysql> insert into DeleteAllFromTable values(103,'Sam'); Query OK, 1 row affected (0.19 sec)
The following is the query to display all the records −
mysql> select *from DeleteAllFromTable;
The following is the output −
+----------+------------+ | PersonId | PersonName | +----------+------------+ | 100 | Johnson | | 101 | John | | 102 | Carol | | 103 | Sam | +----------+------------+ 4 rows in set (0.00 sec)
Now delete all the records from the table with the help of TRUNCATE command. The query is as follows −
mysql> TRUNCATE TABLE DeleteAllFromTable; Query OK, 0 rows affected (0.80 sec)
Since we deleted all the records above, therefore no record would be displayed when we will use the SELECT statement −
mysql> select *from DeleteAllFromTable; Empty set (0.00 sec)
Look at the above output, there are no records in the table.
