Hello All, I have a SQL query I need help with: Here are my tables:
mysql> desc file; +-------------------------+---------------------+------+-----+---------+---- ---+ | Field | Type | Null | Key | Default | Extra | +-------------------------+---------------------+------+-----+---------+---- ---+ | file_name | char(255) | | PRI | | | | required_security_level | tinyint(1) unsigned | | | 0 | | | checked_out_by | char(20) | YES | | NULL | | | date_checked_out | datetime | YES | | NULL | | +-------------------------+---------------------+------+-----+---------+---- ---+ 4 rows in set (0.00 sec) mysql> desc staff; +----------------+---------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------------+---------------------+------+-----+---------+-------+ | username | char(20) | | PRI | | | | last_name | char(30) | | | | | | first_name | char(30) | | | | | | security_level | tinyint(1) unsigned | | | 0 | | +----------------+---------------------+------+-----+---------+-------+ 4 rows in set (0.00 sec) What I want to do is display to the user a list of files that require a security level that is less than or equal to the user's security level, with formatted last name and first name and date if the file is checked out. Checked out by is a foreign key refering to username in the staff table, and the security level and required security level are also related. This is my attempt: SELECT file_name, CONCAT(last_name, ', ', first_name) AS name, DATE_FORMAT(date_checked_out,'%b %D, %Y (%r)') AS date FROM file LEFT JOIN staff ON file.checked_out_by = staff.username WHERE staff.username = 'mike' AND staff.security_level > file.required_security_level; Anyway, any help with this query would be greatly appreciated.
