Addition

Sums up two numbers.

Examples

        1 + 2 + 3 AS add_example2,
        1.1 + 2.2 AS add_example3
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

add_example1	add_example2	add_example3
2	6	3.3000000000000003

Subtraction

Subtracts one number from another.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        1 - 1 AS sub_example1,
        1 - 2 - 3 AS sub_example2,
        2.2 - 1.1 AS sub_example3
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

sub_example1	sub_example2	sub_example3
0	-4	1.1

Negation

Negates the value of a number.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        - 1 AS neg_example1,
        - (- 1) AS neg_example2,
        - 0 AS neg_example3
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

neg_example1	neg_example2	neg_example3
-1	1	0

Multiplication

Multiplies two numbers.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        1 * 0 AS mult_example1,
        1 * 2 * 3 AS mult_example2,
        1.1 * 2.2 AS mult_example3
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

mult_example1	mult_example2	mult_example3
0	6	2.4200000000000004

Division

Divides one number with another.

Note that when dividing integers, the result is truncated, meaning that only the integer portion of the result is returned if the numbers do not divide evenly.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        4 / 2 AS div_example1,
        4 / 2 / 2 AS div_example2,
        3 / 4 AS div_example3,
        2.2 / 3.3 AS div_example4
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

div_example1	div_example2	div_example3	div_example4
2	1	0	0.6666666666666667

Integer division

Divides one integer from another.

Inputs that are not integers are truncated and then divided.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        4 _/ 3 as div_example1,
        4.1 _/ 3.1 as div_example2,
        4.1 / 3.1 as div_example3,
        4.8 _/ 3.8 as div_example4,
        4.8 / 3.8 as div_example5,
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

div_example1	div_example2	div_example3	div_example4	div_example5
1	1	1.3225,806451612903	1	1.263157894736842

Modulus

Computes the modulus (remainder) from dividing one number with another.

Examples

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        4 % 3 AS mod_example1,
        10 % 4 % 2 AS mod_example2,
        5.5 % 2.2 AS mod_example3
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

mod_example1	mod_example2	mod_example3
1	0	1.0999999999999996

Power

Raises one number to the power of another.

This operator has the same functionality as POW and POWER.

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        2 ^ 2 AS pow_example1,
        3.3 ^ 1.1 AS pow_example2
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 1;

Query result

pow_example1	pow_example2
4	3.718479005997499

Example with sample data

The following example uses Upsolver sample data that is available to you through SQLake.

SQL

CREATE JOB function_operator_example
    ADD_MISSING_COLUMNS = true	
    AS INSERT INTO default_glue_catalog.upsolver_samples.orders_transformed_data MAP_COLUMNS_BY_NAME
    SELECT 
        orderid AS order_id,
        ROUND(nettotal / (1 + taxrate), 2) AS pretax_total,
        taxrate,
        nettotal
    FROM default_glue_catalog.upsolver_samples.orders_raw_data 
    WHERE time_filter()
    LIMIT 3;

Query result

order_id	pretax_total	taxrate	nettotal
NzwdlehpJ9	349.98	0.12	391.98
6nDo5vqL3B	741.95	0.12	830.98
