Let us first create a table −
mysql> create table DemoTable815(Gender BOOLEAN); Query OK, 0 rows affected (0.84 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable815 values(true); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable815 values(false); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable815 values(false); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable815 values(true); Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable815;
This will produce the following output −
+--------+ | Gender | +--------+ | 1 | | 0 | | 0 | | 1 | +--------+ 4 rows in set (0.00 sec)
Following is the query to extract gender as a string when it is stored in the table as a boolean −
mysql> select if(Gender=true,'MALE','FEMALE') AS String from DemoTable815;
This will produce the following output −
+--------+ | String | +--------+ | MALE | | FEMALE | | FEMALE | | MALE | +--------+ 4 rows in set (0.00 sec)
