Hi, I have a table in postgresql db with the following description. - Table: vyapar_user CREATE TABLE vyapar_user ( loginid varchar(150) NOT NULL, name varchar(150) NOT NULL, "password" varchar(32) NOT NULL, "type" varchar(10) NOT NULL, address varchar(100) NOT NULL, phone varchar(15), email varchar(20), creationdate date DEFAULT date('now'::text), expriydate date DEFAULT (date('now'::text) + 360), CONSTRAINT vyapar_user_pk PRIMARY KEY (loginid) ) WITH OIDS; If i try inserting NULL values from backend, then it gives me an error. But thru php, its adds null values without any errors. Any idea how to solve this issue.....
