SQL LOCATE command to search strings in fields
We can use the LOCATE string command in our SQL to get the position of a string present inside another string. Let us try this command.
This query will return 8 as the searched string is located at the 8th position within the string. Now let us apply this LOCATE command to search for the presence of the name john in the name field (column ) of our student table.
SELECT * FROM `student` WHERE locate( 'john', name )
The output of this query is here.
As you can see we have collected all the records having 'john' in any place in the name column of the student table.
|John Mike|| Four5|| 60|| male|
|Alex John|| Four5|| 55|| male|
|My John Rob||Fifth5|| 78||male|
|Big John|| Four5|| 55 ||male|
|Babby John|| Four5|| 69|| male|
Now let us apply this Locate query to our student table to search for the location of the string 'john'
SELECT locate('john',name) as position,name FROM `student`
The above command will return all the records of with the position of the searched string, if it is not found then 0 is returned. ( Few sample records are displayed here )
