MySQL fuzzy query can use INSTR instead of LIKE

The NSTR() function returns the position of the first occurrence of a substring in a string.The INSTR() function returns zero (0) if the substring is not found in str.
The syntax of the INSTR function is described below.

INSTR(str,substr);

The INSTR function accepts two parameters:

str is the string to search for.
substr is the substring to search for.

MySQL INSTR function example

The following statement returns the position of the substring SQL in the MySQL INSTR string.

SELECT INSTR('MySQL INSTR', 'SQL');

Execute the above query and get the following results:

mysql> SELECT INSTR('MySQL INSTR', 'SQL');+--------------------------------------------+| INSTR('MySQL INSTR', 'SQL') |+--------------------------------------------+| 3 |+--------------------------------------------+1 row in set

Example 2

SELECT * FROM sys_user where INSTR(name, 'a' )>0

Finds users whose username contains a, similar to LIKE '%a%'.
