Обсуждение: [Novice] Create Table

Hello All,

  I am a real novice to postgresql and am having trouble creating a new
table in my existing database through the psql monitor.

  I have read the programmers guide, the create table syntax, and searched
for some examples but with no luck.  Are there any good examples of step by
step how to create a new table?

Have you tried simply typing in something like this:

CREATE TABLE my_table (
        id              SERIAL NOT NULL PRIMARY KEY,
        column1         int,
        column2         text
);

What sort of errors are you getting?

You can see the full syntax for the create statement with a simple:

\help create table

on the command line.

Yes.  Bruce Momjian's book, "PostgreSQL: Introduction and Concepts" has
 an excellent brief tutorial for the beginner.  It is available from
 online bookstores in several languages.

You need to be in the database that you want to create a table. Example:

psql testdb    <--- This puts you in the testdb database

testdb=#    <--- You should see this now
From here, you can create the table as below:

testdb=# create table test
( testid SERIAL PRIMARY KEY,
  testname VARCHAR(20) NOT NULL DEFAULT '',
  testdate DATE,
  quantity INTEGER,
  amount NUMERIC(8,2)
);

This will create a table. Standard SQL syntax. Try to pick up Bruce
Momjian's book 'PostgreSQL Introduction and Concepts'
