Postgresql Column Does Not Exist
ERROR: column "foo" does not exist I have checked myself that his column indeed exists. If I do something like: SELECT * from table_name where count is NULL The resulting output shows 'foo' as one of the columns.... I am guessing I have to do something special in the query because foo is a text column...

There should be a setting in phpPGadmin somewhere that will tell it to not quote identifiers (such as table and column names) but alas, I don't use phpPGadmin so I don't where that setting is (or eve

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-stateme
not exist Category: How To 4 Comments When I run the following SQL command in PostgreSQL: select * from projects where Status='Inactive' I get the following error: ERROR: column "status" does http://www.cyprich.com/2008/10/01/postgres-column-field-does-not-exist/ not exist This is a very frustrating and confusing error because the http://dba.stackexchange.com/questions/40691/error-column-does-not-exist-in-a-select-with-join-and-group-by-query same SQL command works in MS SQL Server and MySQL. After some research, I discovered that Postgres converts all column names in a table to lower case in a SQL query. The problem can be fixed by enclosed a table name that has mixed case with double quotation does not marks: select * from projects where "Status"='Inactive' The query will then work as expected.

I'm trying to list the last version of each "charge" (in my history table : hist_version_charges) belonging to the same project id (proj_sous_projet_id = 2). This makes me use the max() aggregate function and apply the result to a JOIN function on the same table as PostgreSQL does not authorize to use the columns in the SELECT clause if they do not appears in the GROUP BY clause, ALTHOUGH using a max() mean obviously I'm interested to the row containing the max values! This is my query : SELECT h_v_charges.*, max(last_v.version) as lv FROM hist_versions_charges h_v_charges JOIN hist_versions_charges last_v ON h_v_charges.version = lv AND h_v_charges.proj_charge_id = last_v.proj_charge_id GROUP BY last_v.proj_sous_projet_id, last_v.proj_charge_id HAVING last_v.proj_sous_projet_id = 2 ORDER BY h_v_charges.proj_charge_id ASC; The error message I got : ERROR: column "lv" does not exist LINE 1: ..._versions_charges last_v ON h_v_charges.version = lv AND h_v... ^ ********** Error ********** ERROR: column "lv" does not exist SQL state: 42703 Character: 147 I also tried with "last_v.lv" but the error remains the same.
