To convert string to bitset, use the CONV() method. Let us first create a table −
mysql> create table DemoTable ( stringValue BIT(4) ); Query OK, 0 rows affected (3.50 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(CONV('1110', 2, 10) * 1); Query OK, 1 row affected (0.62 sec) mysql> insert into DemoTable values(b'1011'); Query OK, 1 row affected (0.14 sec)
Following is the query to display all records from the table using select statement −
mysql> select *from DemoTable;
Following is the output that displays blank result because the type is bitset −
Following is the query to convert string to bitset and display the result −
mysql> select stringValue+0 AS DECIMAL_VALUE,BIN(stringValue) AS BINARY_VALUE from DemoTable;
This will produce the following output −
+---------------+--------------+ | DECIMAL_VALUE | BINARY_VALUE | +---------------+--------------+ | 14 | 1110 | | 11 | 1011 | +---------------+--------------+ 2 rows in set (0.04 sec)
