I use this code to create and add the constraint to the table. CREATE TABLE Ereignis( E_Id Serial PRIMARY KEY, Typ varchar(15), Zeitpunkt timestamp, Ort varchar(32), Anzahl_Pers int ); ALTER TABLE Ereignis ADD CONSTRAINT typ_ch CHECK (Typ in (’Verkehrsunfall’, ’Hochwasser’, ’Sonstiges’)); Here is the error I get: ERROR: column "’verkehrsunfall’" does not exist As I get from this error it tries to compare column typ with column verkehrsunfall, where as I try to check the values that column try can get is one of the (’Verkehrsunfall’, ’Hochwasser’, ’Sonstiges’) strings. This is exactly the same syntax what our lecturer showed us at the lecture. I am not sure if it is possible to compare varchars with check? Or what am I doing wrong? Here is the example from the lecture: CREATE TABLE Professoren (PersNr INTEGER PRIMARYKEY, Name VARCHAR( 3 0 ) NOT NULL , Rang CHAR(2) CHECK (Rang in ('C2' ,'C3' ,'C4')) , Raum INTEGER UNI

You created your table using double quotes for the column names, which makes them case sensitive and you must use double quotes all the time: INSERT INTO dxtest_loadprofiletosale (id, "TransDate", "IssueDate", "CustomerNum") VALUES (1, '2015-03-04','2015-01-01',01); More details about SQL identifiers are in the manual: http://www.postgresql.org/docs/curr

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 does not exist 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. If anybody got an idea about what's wrong, she is more than welcome. === UPDATE === According to * a_horse_with_no_name * and Colin 't Hart answers, I finally ended up with the following query : SELECT * FROM ( SELECT *, max(version) OVER (PARTITION BY proj_charge_id) AS lv FROM hist_versions_charges WHERE proj_sous_projet_id = 2) AS hv WHERE hv.lv = hv.version ORDER BY hv.proj_charge_id ASC; It is slightly quicker with a single OR
