error with parenthesis on pgSQL

Question

using phpPgAdmin, I've tried to create a table in my database. But am getting an error after it has generated its code.

SQL error:

ERROR:  syntax error at or near "(" at character 91

CREATE TABLE "public"."main_products_common_dimensions" ("id" SERIAL, "product_id" integer(3) NOT NULL, "h_ft" character varying(15), "h_in" character varying(15), "w_ft" character varying(15), PRIMARY KEY ("id")) WITHOUT OIDS

What could be wrong with the parenthesis?

Answer 1

The problem - you cannot specify precision for integer type, so integer(3) is invalid type. Use numeric(3) or simple integer .

Answer 2

没有integer(3) ：postgresql integer总是4个字节，有符号。
