Performing a MySQL LIKE comparison on an INT field?
You need to use cast() method to perform comparison on an INT field. The syntax is as follows −
SELECT yourColumnName1,yourColumnName2,......N yourTableName WHERE CAST(yourColumnName as CHAR) LIKE ‘%yourIntegerValue%’;
To understand the above syntax, let us create a table. The following is the query to create a table for performing a LIKE comparison on INT field −
mysql> create table ComparisonOnIntField -> ( -> StudentId int NOT NULL, -> StudentName varchar(20), -> StudentAge int -> ); Query OK, 0 rows affected (1.00 sec)
Insert some records in the table to perform a MySQL LIKE comparison on an INT field. The query to insert record is as follows −
mysql> insert into ComparisonOnIntField values(10,'Carol',24); Query OK, 1 row affected (0.17 sec) mysql> insert into ComparisonOnIntField values(12,'Bob',21); Query OK, 1 row affected (0.18 sec) mysql> insert into ComparisonOnIntField values(14,'Sam',23); Query OK, 1 row affected (0.10 sec) mysql> insert into ComparisonOnIntField values(16,'Mike',25); Query OK, 1 row affected (0.26 sec) mysql> insert into ComparisonOnIntField values(18,'John',27); Query OK, 1 row affected (0.14 sec) mysql> insert into ComparisonOnIntField values(20,'David',26); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from ComparisonOnIntField;
The following is the output.
+-----------+-------------+------------+ | StudentId | StudentName | StudentAge | +-----------+-------------+------------+ | 10 | Carol | 24 | | 12 | Bob | 21 | | 14 | Sam | 23 | | 16 | Mike | 25 | | 18 | John | 27 | | 20 | David | 26 | +-----------+-------------+------------+ 6 rows in set (0.00 sec)
Here is the query to perform a MySQL LIKE comparison on an INT field −
mysql> select StudentName,StudentAge from ComparisonOnIntField -> where cast(StudentId as CHAR) Like '%18%';
The following is the output −
+-------------+------------+ | StudentName | StudentAge | +-------------+------------+ | John | 27 | +-------------+------------+ 1 row in set (0.05 sec)
