Amid tons of data, finding a particular string's presence in the data is extremely tedious. MySQL has a command named LOCATE that can be used with certain conditions and the yield is truly useful.
Using the LOCATE Command
LOCATE ("<search string>", column_name, <start index - Optional>)
For example, if we are trying to look for a string called "JAMES" in the column NAME from a table named EMPLOYEE_DETAILS, the following SQL will be able to make the needed query.
SELECT LOCATE("JAMES", NAME) FROM EMPLOYEE_DETAILS;
Assuming there are 5 records in the table and the values JAMES is present in row # 3, the output will be as follows.
+ -- -- -- -- -- -- -- -- -- -- -- -- -- +
|LOCATE("JAMES", NAME) |
