Hi all
In looking for how to do table constraints psql help says:
software=> \h create table
Command: create table
Description: create a new table
Syntax: CREATE TABLE class_name (attr1 type1 [DEFAULT expression] [NOT NULL], ...attrN) [INHERITS
(class_name1,...class_nameN) [[CONSTRAINT name] CHECK condition1, ...conditionN] ]
;
But this both does not work, and does not agree with "The Practical SQL
Handbook", the examples of which do work.
Should the syntax not be more like: (constraint inside the main parens)
Command: create table
Description: create a new table
Syntax: CREATE TABLE class_name (attr1 type1 [DEFAULT expression] [NOT NULL][, ...attrN]
[,[CONSTRAINTname] CHECK condition1, ...conditionN] ]);
I'm not sure where to put: [INHERITS (class_name1, ...class_nameN)
as I've never used it. But I suspect it may need inside the '()' as well,
no?
OH, also, what is / is there, a comment character to use in SQL scripts
feed into psql?
Have a great day
