Question

I have two files that both work fine when executing them in Postgres.

File 1

CREATE TABLE ContractStatusEnum (
    id              SERIAL PRIMARY KEY,
    description         VARCHAR(4000) NOT NULL
);

*File 2

DO $$ BEGIN

    IF NOT EXISTS (SELECT * FROM ContractStatusEnum WHERE id = 1) THEN
    INSERT INTO ContractStatusEnum (id, description) VALUES
        (1, 'Ordered'),
        (2, 'Active'),
        (3, 'Stopped'),
        (4, 'Canceled'),
        (10, 'Inactive');
    END IF;
END $$

However, if I just put them together in one file, it fails with

ERROR: syntax error at or near “DO”
LINE 6: DO $$ BEGIN

On MS SQL I can solve this by creating a new context by putting a GO statement between two scripts. Any clue how to do it in Postgres 9?

Answer 1

You need to terminate your DO block with a semicolon.

The following works for me:

DO $$ BEGIN

    IF NOT EXISTS (SELECT * FROM ContractStatusEnum WHERE id = 1) THEN
    INSERT INTO ContractStatusEnum (id, description) VALUES
        (1, 'Ordered'),
        (2, 'Active'),
        (3, 'Stopped'),
        (4, 'Canceled'),
        (10, 'Inactive');
    END IF;
END $$
;

I saved the statements in f1.sql (create table) and f2.sql (do block):

psql (9.1.3)
Type "help" for help.

postgres=> \i f1.sql
CREATE TABLE
postgres=> \i f2.sql
DO
postgres=>
