Examples

Variable used in an OVERRIDE load step

Given mapping:

Target entity: publish.D_RATECODE

Source entity: src.SOURCE

source attributes	Formula	Target attribute
attribute_a,attribute_b,attribute_c	HASH	key_id
	RUN_ID	run_id
attribute_d		information

OVERRIDE load step in D_RATECODE entity:

SQL

insert into <target_schema>.<target_entity_name>
select <target_entity_attribute_list_with_transform>
from <source_entity_schema>.<source_entity_name>;

Load executed in the target database Snowflake:

SQL

insert into publish.D_RATECODE
select MD5(UPPER(NVL(attribute_a, '-1') || '~' || NVL(attribute_b, '-1')|| '~' || NVL(attribute_c, '-1'))) AS key_id,
       <timemillis> AS run_id,
       attribute_d AS information
from src.SOURCE;

Load executed in the target database BigQuery:

SQL

insert into publish.D_RATECODE
select TO_HEX(MD5(UPPER(CONCAT(COALESCE(CAST(attribute_a AS STRING), '-1'),'~',COALESCE(CAST(attribute_b AS STRING), '-1'),'~',COALESCE(CAST(attribute_c AS STRING), '-1'))) AS key_id,
       <timemillis> AS run_id,
       attribute_d AS information
from src.SOURCE;

Load executed in the target database Databricks:

SQL

insert into publish.D_RATECODE
select MD5(UPPER(COALESCE(CAST(attribute_a AS STRING), '-1') || '~' || COALESCE(CAST(attribute_b AS STRING), '-1')|| '~' || COALESCE(CAST(attribute_c AS STRING), '-1'))) AS key_id,
       <timemillis> AS run_id,
       attribute_d AS information
from src.SOURCE;

SQL

insert into [publish].[D_RATECODE]
select CONVERT(VARCHAR(32),HASHBYTES('MD5', UPPER(TRIM(COALESCE([attribute_a], '-1'))  + '~' + TRIM(COALESCE([attribute_b], '-1')) + '~' + TRIM(COALESCE([attribute_c], '-1')))),2) AS [key_id],
       <timemillis> AS [run_id],
