Re: [GENERAL] How to define the limit length for numeric type?

Hi everyone,

How to define the exact limit length of numeric type? For example,

CREATE TABLE test  (id serial, goose numeric(4,1));

300.2 and 30.2 can be inserted into COLUMN goose, but I want 30.2 or 3.2 can not be inserted, how to do this?

ostgres=# CREATE TABLE test  (id serial, goose numeric(4,1));
CREATE TABLE
Time: 351,066 ms
postgres=# insert into test values(1,3.2);
INSERT 0 1
Time: 65,997 ms
postgres=# select * from test;
┌────┬───────┐
│ id │ goose │
╞════╪═══════╡
│  1 │   3.2 │
└────┴───────┘
(1 row)

Time: 68,022 ms

Thank you.
