Hello everyone, I would like to remove the leading zeros from some attributes. This is not a problem with the normal extractions and can be done with an update command. The question arises as to how I can implement this in the Replication Cockpit. The data is stored in a view, which I cannot update. Does anyone already have a solution for this or a suggestion as to how I can implement this?
Hi Jonas,
In your Replication Cockpit when selecting a table you have the option of Transformation Configuration. These Transformations will be triggered by the corresponding extractions. If you want to update your view, a pracitcal approach (perhaps not the most efficient one) would be to simply create a table from the view, update the table, save it back to a view and replace the views with eachother.
This could be an example of the transformation you are looking for:
-- Transform the view into a table
CREATE TABLE SampleTable AS
SELECT *
FROM SampleView;
-- Alter the table to trim leading zeros
ALTER TABLE SampleTable
ADD COLUMN TrimmedValue VARCHAR(255); -- Assuming VARCHAR(255) as the data type
UPDATE SampleTable
SET TrimmedValue = LTRIM(Value, '0');
-- Drop the original view
DROP VIEW IF EXISTS SampleView;
-- Create a new view with the transformed data
CREATE VIEW SampleView AS
SELECT TrimmedValue AS Value
FROM SampleTable;
-- Drop the temporary table
DROP TABLE IF EXISTS SampleTable;
I hope this helps.
Best regards,
Tim
