What's the default value of “inet” and “cidr” type in PostgreSQL?

When I execute the SQL:



CREATE TABLE IF NOT EXISTS "xxx" (

    "id" serial NOT NULL PRIMARY KEY,

    "ip" inet NOT NULL DEFAULT '',

    "mac_address" macaddr NOT NULL DEFAULT '',

    "status" varchar(64) NOT NULL DEFAULT ''

);


It reports an error:



execute error: pq: invalid input syntax for type macaddr: ""


So what's the default value of "inet" and "cidr" type in PostgreSQL?






sql postgresql ip mac-address

    Why NOT NULL combined with an empty string as default value?

    Only you know what's the default value supposed to be, there's no default DEFAULT

I would be inclined to go with NULL values, instead of some default.



But, you can put in your own values if you follow the specified formats:



CREATE TABLE IF NOT EXISTS "xxx" (

    "id" serial NOT NULL PRIMARY KEY,

    "ip" inet NOT NULL DEFAULT '0.0.0.0'::inet,

    "mac_address" macaddr NOT NULL DEFAULT '00-00-00-00-00-000'::macaddr,

    "status" varchar(64) NOT NULL DEFAULT ''

);

SQL update select statement

Image
0 I'm trying to update an entry in my database (postgresql). I'm having a problem with updating the query: INSERT INTO prices (price, product_id) SELECT product_price, commn_id FROM products_temp as prod WHERE NOT EXISTS (SELECT * FROM prices od WHERE prod.commn_id = od.product_id) OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) Query works fine when i delete: OR prod.product_price != ( SELECT price FROM prices as p WHERE p.product_id = prod.commn_id order by p.end desc LIMIT 1 ) So it seems to me that it's looping through this operation. My question is, how can I fix it? sql postgresql
