How to count the number of rows containing APOSTROPHE in MySQL?

I need to count the number of rows containing "'" APOSTROPHE in a particular field of my table. I made try to do so like below:

SELECT COUNT(*) FROM my_table WHERE field_name LIKE "%'%"
But I get 0 row in result. Whereas I am sure that "'" exists in many rows.   So pls explain, how to count the number of rows containing apostrophe in MySQL?

Answer No: 129

You are doing right but one thing is missing.  You can correct your query only to escape the apostrophe.  I will rewrite your query like below:

SELECT COUNT(*) FROM my_table WHERE field_name LIKE "%\'%"
