Can someone help point out to me what is wrong with this no brainer WHERE clause?
Try with single quotes '' if you are trying to match a string
SELECT login FROM accounts WHERE login = 'loginname';Check the documentation
There is a second kind of identifier: the delimited identifier or quoted identifier. It is formed by enclosing an arbitrary sequence of characters in double-quotes ("). A delimited identifier is always an identifier, never a key word. So "select" could be used to refer to a column or table named "select", whereas an unquoted select would be taken as a key word and would therefore provoke a parse error when used where a table or column name is expected.
Double quotes (") are used to refer to object names, in a case sensitive way. In this case, "loginname" is interpreted as a column name, and the query fails, since there is no such column. In order to refer to a string literal, you should use single quotes ('):
SELECT login FROM accounts WHERE login = 'loginname';-- Here ---------------------------------^---------^
It seems that the " " are the problem if you believe the documentation. Single quotes are required for string values.
