我已经习惯了SQL Server中的查询编辑器,可以自由编写&执行T-SQL。如何在PostgreSQL中执行以下代码而无需从中创建函数?
DECLARE
l integer = 1;
BEGIN
CREATE TABLE product_i (id bigint, key integer, value integer);
CREATE INDEX ix_product_i_size ON product_i(value) WHERE key = 1;
CREATE INDEX ix_product_i_mass ON product_i(value) WHERE key = 2;
LOOP
BEGIN;
INSERT
INTO product_i (id, key, value)
SELECT id, 1, CEILING(10 + RANDOM() * 90)
FROM generate_series(l, 1000) id;
INSERT
INTO product_i (id, key, value)
SELECT id, 2, CEILING(10 + RANDOM() * 90)
FROM generate_series(l, 1000) id;
COMMIT;
l := l + 1000;
EXIT WHEN l > 5000;
END LOOP;
END

如果您至少使用PostgreSQL 9.0,则可以将其包含在DO块中:
