SQL - Query to find if a string contains part of the value in Column

The answer would be "use LIKE".

See the documentation: https://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html

You can do WHERE 'string' LIKE CONCAT(column , '%')

Thus the query becomes:

select * from t1 where 'ABCDEFG' LIKE CONCAT(column1,'%');

If you need to match anywhere in the string:

select * from t1 where 'ABCDEFG' LIKE CONCAT('%',column1,'%');

Here you can see it working in a fiddle: http://sqlfiddle.com/#!9/d1596/4

Select * from table where @param like '%' + col + '%'
