Create Column Names dynamically
I have the following task that I am having problems with.
1. THIS IS DONE - Check for distinct MODEL_NAME value in TABLE 1 and see what MODEL_NAME value is missing in TABLE 2 (could be multiple).
Here is SQL - THIS WORKS
2. THIS IS DONE - Stored Prodecure that inserts new values into TABLE 2 with the following data, (id, dte, device_type) - this works as well.
SELECT DISTINCT a.device_type
FROM logrelay.ra_device_type_hist@PRLDW a
WHERE a.device_type is not null
FROM rkiss.device_models b
3, HERE IS MY PROBLEM.
I have TABLE 3 where DEVICE_TYPE from TABLE 2 are column names. Currently I add column names manually, but would like to automate this process.
I would like to create a process that would check any new DEVICE_TYPE values in TABLE 2 that does not exist as column names in TABLE 3. If new DEVICE_TYPE value exists in TABLE 2, create new column name (as value of the new DEVICE_TYPE in TABLE 2) in TABLE 3.
I do not how to code this.
