Join Index

Translation reference to convert Teradata Join Index to Snowflake Dynamic Table

Description

In Snowconvert, Teradata Join Indexes are transformed into Snowflake Dynamic Tables. To properly configure Dynamic Tables, two essential parameters must be defined: TARGET_LAG and WAREHOUSE. If these parameters are left unspecified in the configuration options, Snowconvert will default to preassigned values during the conversion, as demonstrated in the example below.

Sample Source Patterns

Teradata

IN -> Teradata_01.sql
CREATE JOIN INDEX Employee
AS   
SELECT 
  Employee_Id,
  First_Name,
  Last_Name,
  BirthDate,
  DepartmentNo   
FROM Employee   
PRIMARY INDEX (First_Name); 

Snowflake

OUT -> Teradata_01.sql
CREATE OR REPLACE DYNAMIC TABLE Employee_JI
--** SSC-FDM-0031 - DYNAMIC TABLE REQUIRED PARAMETERS SET BY DEFAULT **
TARGET_LAG='1 day'
WAREHOUSE=UPDATE_DUMMY_WAREHOUSE
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"teradata"}}'
AS
SELECT
  Employee_Id,
  First_Name,
  Last_Name,
  BirthDate,
  DepartmentNo
FROM Employee;
