Postgres Column Does Not Exist At Character
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 since it contains an uppercase N. I am trying to query the database with the following statement: SELECT * FROM employee WHERE "lName" LIKE "Smith" But I am receive this error: Warning: pg_query() [function.pg-query]: Query failed: ERROR: column "Smith" does not exist in .....

issue here? Why is it saying the column is "Smith"? php postgresql share|improve this question asked Apr 27 '11 at 6:22 meenxo 3771510 add a comment| 2 Answers 2 active oldest votes up vote 19 down vote accepted I would guess: SELECT * FROM employee WHERE "lName" LIKE 'Smith' (note the different quotes; "foo" is a quoted identifier; 'foo' is a string literal) Also, in most SQL dialects, a LIKE without a wildcard is equivalent to =; did you mean to include a wildcard? share|improve this answer answered Apr 27 '11 at 6:25 Marc Gravell♦ 628k14617542224 add a comment| up vote 4 down vote 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. share|improve this answer answered Apr 27 '11 at 7:37 Peter Eisentraut 19.6k44964 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a gu

If that's not what you're doing, maybe edit and explain what your real goal is because it's hard to imagine a funtion like this having a use where there isn't a better way to do it. –Craig Ringer Jul 4 '13 at 11:08 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Your code has no chance to work - when dealing with different tables in PLPGSQL you need to utilize dynamic queries, so EXECUTE is required - http://www.postgresql.org/docs/current/static/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN But first of all - there is nothing bad in using PostgreSQL EXISTS - http://www.postgresql.org/do

Brought to you in partnership with ZeroTurnaround. I’ve been playing around with PostgreSQL recently and in particular the Northwind dataset typically used as an introductory data set for relational databases. Having imported the data I wanted to take a quick look at the employees table: postgres=# SELECT * FROM employees LIMIT 1; EmployeeID | LastName | FirstName | Title | does not exist TitleOfCourtesy | BirthDate | HireDate | Address | City | Region | PostalCode | Country | HomePhone | Extension | Photo | Notes | ReportsTo | PhotoPath ------------+----------+-----------+----------------------+-----------------+------------+------------+-----------------------------+---------+--------+------------+---------+----------------+-----------+-------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+-----------+-------------------------------------- 1 | Davolio | Nancy | Sales Representative | Ms. | 1948-12-08 | 1992-05-01 | 507 - 20th Ave. E.\nApt. 2A | Seattle | WA | 98122 | USA | (206) 555-9857 | 5467 | \x | Education includes a BA IN psychology FROM Colorado State University IN 1970.
