I would like to ask a question about MYSQL. if the database stores a short string: ABBCCD, then the words in my hand are long strings, such as & nbsp; ABCD, how should I write SQL statements, which of the following keywords can match the string? Do I need to use CONCAT for connecting? In addition, when saving these short strings to the database, how can we ensure security? will there be risks such as injection? Thank you for your question about MYSQL.
If the database contains a short string:
AB
BC
CD
So the word in my hand is a long string, such as ABCD. how should I write the SQL statement to match the character that contains the short word records in several libraries? Do I need to use CONCAT for connecting?
In addition, when saving these short strings to the database, how can we ensure security? will there be risks such as injection?
Thank you.

Yes
Select * from tbl_name where 'ABC' like concat ('%', field_name, '% ')
