i don't believe instantdb supports the constraint keyword. i think you need
to setup a compound index with unique on it

Subject: InstantDB: constraint usage


Hi:
      I could not find an example of using contraint with instantDB, and
keep getting parser errors.  

      What I want is to declare id and principal as primary keys in my_test
table, but I will get SQLException 

      Don't understand SQL after: "CREATE"
      Expected: "UNIQUE" found: "CONSTRAINT"



e CREATE TABLE my_test_parent(
           id numeric(19,0) auto increment primary key 
   );

e CREATE TABLE my_test(
 	id  numeric(19,0)  NOT NULL ,
	principal varchar (255)  NOT NULL ,
	test varchar (20) NULL ,
	num Value numeric(10,0) NULL,
 
	CONSTRAINT  PRIMARY KEY id, principle
            CONSTRAINT  FOREIGN KEY  id  REFERENCES  my_test_parent
);


TIA

Chiwei
