Let us first create a table. We have set one of the columns with type TINYINT −
mysql> create table DemoTable -> ( -> EmployeeId int, -> isMarried tinyint -> ); Query OK, 0 rows affected (6.84 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(101,true); Query OK, 1 row affected (1.94 sec) mysql> insert into DemoTable values(102,false); Query OK, 1 row affected (0.76 sec) mysql> insert into DemoTable values(103,true); Query OK, 1 row affected (1.14 sec) mysql> insert into DemoTable values(104,true); Query OK, 1 row affected (1.22 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------+----------+ | EmployeeId | isMarried| +------------+----------+ | 101 | 1 | | 102 | 0 | | 103 | 1 | | 104 | 1 | +------------+----------+ 4 rows in set (0.00 sec)
Here is the query to implement UPDATE statement with TINYINT −
mysql> update DemoTable -> set isMarried=false -> where EmployeeId=103; Query OK, 1 row affected (1.24 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+------------+----------+ | EmployeeId | isMaried | +------------+----------+ | 101 | 1 | | 102 | 0 | | 103 | 0 | | 104 | 1 | +------------+----------+ 4 rows in set (0.00 sec)
