SnowConvert: Redshift Expressions¶

Expression lists¶

Description¶

An expression list is a combination of expressions, and can appear in membership and comparison conditions (WHERE clauses) and in GROUP BY clauses. (Redshift SQL Language Reference Expression lists).

This syntax is fully supported in Snowflake.

Grammar Syntax

Sample Source Patterns

Setup data

 CREATE TABLE table1 (
    quantity VARCHAR(50),
    fruit VARCHAR(50)
);

CREATE TABLE table2 (
    quantity VARCHAR(50),
    fruit VARCHAR(50)
);

CREATE TABLE table3 (
    id INT,
    name VARCHAR(50),
    quantity INT,
    fruit VARCHAR(50),
    price INT
);

INSERT INTO table1 (quantity, fruit)
VALUES
    ('one', 'apple'),
    ('two', 'banana'),
    ('three', 'cherry');

INSERT INTO table2 (quantity, fruit)
VALUES
    ('one', 'apple'),
    ('two', 'banana'),
    ('four', 'orange');

INSERT INTO table3 (id, name, quantity, fruit, price)
VALUES
    (1, 'Alice', 1, 'apple', 100),
    (2, 'Bob', 5, 'banana', 200),
    (3, 'Charlie', 10, 'cherry', 300),
    (4, 'David', 15, 'orange', 400);

Copy

IN Clause

Input Code:

SELECT *
FROM table3
WHERE quantity IN (1, 5, 10);

Copy

ID	NAME	QUANTITY	FRUIT	PRICE
1	Alice	1	apple	100
2	Bob	5	banana	200
3	Charlie	10	cherry	300

Output Code:

 SELECT *
FROM
    table3
WHERE quantity IN (1, 5, 10);

Copy

ID	NAME	QUANTITY	FRUIT	PRICE
1	Alice	1	apple	100
2	Bob	5	banana	200
3	Charlie	10	cherry	300

Comparisons

Input Code:

 SELECT *
FROM table3
WHERE (quantity, fruit) = (1, 'apple');

Copy

ID	NAME	QUANTITY	FRUIT	PRICE
1	Alice	1	apple	100

Output Code:

 SELECT *
FROM
    table3
WHERE (quantity, fruit) = (1, 'apple');

Copy

ID	NAME	QUANTITY	FRUIT	PRICE
1	Alice	1	apple	100

Note

Expression list comparisons with the following operators may have a different behavior in Snowflake. ( < , <= , > , >=). These operators are transformed into logical AND operations to achieve full equivalence in Snowflake.

Input Code:¶

 SELECT (1,8,20) < (2,2,0) as r1,
       (1,null,2) > (1,0,8) as r2,
       (null,null,2) < (1,0,8) as r3,
       (1,0,null) <= (1,1,0) as r4,
       (1,1,0) >= (1,1,20) as r5;

Copy

R1	R2	R3	R4	R5
FALSE	FALSE	NULL	NULL	FALSE

Output Code:¶

 SELECT
    (1 < 2
    AND 8 < 2
    AND 20 < 0) as r1,
    (1 > 1
    AND null > 0
    AND 2 > 8) as r2,
    (null < 1
    AND null < 0
    AND 2 < 8) as r3,
    (1 <= 1
    AND 0 <= 1
    AND null <= 0) as r4,
    (1 >= 1
    AND 1 >= 1
    AND 0 >= 20) as r5;

Copy

R1	R2	R3	R4	R5
FALSE	FALSE	NULL	NULL	FALSE

Nested tuples¶

Input Code:¶

 SELECT *
FROM table3
WHERE (quantity, fruit) IN ((1, 'apple'), (5, 'banana'), (10, 'cherry'));

Copy

ID	NAME	QUANTITY	FRUIT	PRICE
1	Alice	1	apple	100
2	Bob	5	banana	200
3	Charlie	10	cherry	300

        ELSE 'Not Found'
    END AS result

Bitwise operators on binary data¶

For the BITAND, BITOR and BITXOR functions the'LEFT' parameter is added to insert padding in case both binary values have different length, this is done to avoid errors when comparing the values in Snowflake.
