How to search by specific pattern in MySQL?
You can use regular expression for this. Let us first create a table −
mysql> create table DemoTable ( UserId varchar(100) ); Query OK, 0 rows affected (1.28 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('User-123-G');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Us-453-GO');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable values('TRUE-908-K');
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------+ | UserId | +------------+ | User-123-G | | Us-453-GO | | TRUE-908-K | +------------+ 3 rows in set (0.00 sec)
Following is the query to search by specific pattern in MySQL. Here we have set the pattern to be 4 alnum – 3 alnum – 1alnum.
Note − Here – is hyphen −
mysql> select *from DemoTable where UserId regexp '^[[:alnum:]]{4}-[[:alnum:]]{3}-[[:alnum:]]{1}$';This will produce the following output −
+------------+ | UserId | +------------+ | User-123-G | | TRUE-908-K | +------------+ 2 rows in set (0.12 sec)
