MySQL query to check if a certain row has only two words?
For this, use Regular Expression in MySQL as in the below syntax −
select * from yourTableName where yourColumnName regexp '^[^ ]+[ ]+[^ ]+$';
The above query will work when the two words are separated by a space. Let us first create a −
mysql> create table DemoTable1412 -> ( -> Name varchar(40) -> ); Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1412 values('John Adam Carol');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1412 values('Mike Sam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1412 values('Chris James Robert');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select −
mysql> select * from DemoTable1412;
This will produce the following output −
+--------------------+ | Name | +--------------------+ | John Adam Carol | | Mike Sam | | Chris James Robert | +--------------------+ 3 rows in set (0.00 sec)
Here is the query to check if a certain row has two words separated by space −
mysql> select * from DemoTable1412 where Name regexp '^[^ ]+[ ]+[^ ]+$';
This will produce the following output −
+----------+ | Name | +----------+ | Mike Sam | +----------+ 1 row in set (0.00 sec)
