В SELECT-запросах к данным можно использовать функции и операторы, описанные в таблице ниже.

СУБД хранилища имеют ограничения на использование некоторых функций в запросах, вызванные особенностями этих СУБД. Наиболее полный синтаксис запросов доступен в ADB и ADP.

Преобразование типов

Неявное преобразование

bigint_col to boolean: Не поддерживается
SELECT bigint_col = true FROM table1;
int_col to boolean: Не поддерживается
SELECT int_col = true FROM table1;
integer type to boolean within MATERIALIZED VIEW: Не поддерживается
CREATE MATERIALIZED VIEW matview1
(
id int not null,
int_col int,
primary key (id)
)
DISTRIBUTED BY (id)
DATASOURCE_TYPE (adg, adqm)
AS
SELECT * FROM table1 a INNER JOIN table2 c ON a.int_col = true
DATASOURCE_TYPE = 'adb';

CAST

CAST (boolean as int32): Не поддерживается
SELECT CAST(boolean_col as int32) FROM table1;
