Check Constraint Returning Error Upon Creation of Tables

Question

Really simple error when I'm creating some tables and it's probably just me being stupid but I'd rather post it here and have it sorted.

I'm using Postgresql.

(This table is just one of many but it's the one that's giving me a problem)

CREATE TABLE Ticket
(
    ID      INTEGER NOT NULL PRIMARY KEY,
    Problem VARCHAR(1000),
    Status  VARCHAR(20) NOT NULL DEFAULT 'open', 
    Priority    INTEGER NOT NULL,
    LoggedTime  TIMESTAMP NOT NULL,
    CustomerID  INTEGER NOT NULL,
    ProductID   INTEGER NOT NULL,
    FOREIGN KEY (ProductID) REFERENCES Product(ID),
    FOREIGN KEY (CustomerID) REFERENCES Customer(ID),
    CHECK (status='open' OR 'closed' AND priority =  1 OR 2 OR 3)
);

The error:

ERROR: invalid input syntax for type boolean: "closed"

Also if anybody can give me a better method of doing the CHECK:

CHECK (status='open' OR 'closed' AND priority =  1 OR 2 OR 3)

Then that would be really appreciated!

Answer 1

Use

CHECK (Status IN ('open','closed') AND Priority IN (1,2,3))

You could also use

(Status ='open' OR  Status ='closed') AND
      (Priority =  1 OR Priority =  2 OR Priority =  3)
