To select rows in which a particular column value contains a particular word, use LIKE and in inverted commas along with % symbol.
If the values have to start with a certain word, use %word and if the word has to end with a specific word, use word%. Use %word% if the particular word is anywhere in a given column's value. This is a case sensitive method.
Example Query -
select * from yt_records where video_title LIKE '%Mumbai%';
The above query selects all records in which there is a word Mumbai in them.
