Why does using an Underscore character in a LIKE filter give me all the results?

Question

I wrote the below SQL query with a LIKE condition:

SELECT * FROM Manager
WHERE managerid LIKE \'_%\'
AND managername LIKE \'%_%\'

Answer 1

You can write the query as below:

SELECT * FROM Manager
WHERE managerid LIKE '\_%' escape '\'
AND managername LIKE '%\_%' escape '\';

it will solve your problem.
