Transformation job example

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 formatString, inputs1[], inputs2[], inputs3[],
JOIN_ARRAYS('{0} {1} is {2} years old', inputs1[], inputs2[], inputs3[]) AS Output
FROM default_glue_catalog.upsolver_samples.orders_raw_data
LET formatString = '{0} {1} is {2} years old',
inputs1 = array['John', 'Jane'],
inputs2 = array['Smith', 'Johnson'],
inputs3 = array[35, 32]
WHERE time_filter()
LIMIT 1;

Query result

formatString
inputs1[]
inputs2[]
inputs3[]
Output
