Simple Postgresql Statement - column name does not exists

Question

I\'ve been pulling my hair out. I have a very simple postgre database, one specific table has a column named lName (uppercase N). Now I know with postgre I must quote lName

Answer 1

Because "Smith" is an identifier, and in that position, an identifier is expected to be a column. What you probably meant is a string literal, which uses single quotes: 'Smith'. So

SELECT * FROM employee WHERE "lName" LIKE 'Smith'

You probably also want a wildcard in the string to search for ('Smith%'?). LIKE matching is anchored to the beginning and end of a string, unlike typical regular expression matching.
