Moving the FACT table records in Microsoft SQL Server databases
Before you perform this task, make sure you have full access to the source and the destination databases (you need the database admin privileges).
Connect to the source database.
If a table does not exist, execute the following script:
SELECT * INTO <TARGET_DATABASE>.<TARGET_SCHEMA>.PR_DATA_IH_FACT FROM <SOURCE_DATABASE>.<SOURCE_SCHEMA>.PR_DATA_IH_FACT
If a table exists with the exact same columns:
- Make sure there are no primary key (PK) constraints on the PXFACTID column in the destination database and do not move any constraints.
Execute the following script:
INSERT INTO <TARGET_DATABASE>.<TARGET_SCHEMA>.PR_DATA_IH_FACT (column1 [, column2 ...]) SELECT column1 [, column2 ...] FROM <SOURCE_DATABASE>.<SOURCE_SCHEMA>.PR_DATA_IH_FACT
- Applying sample scripts for archiving and purging
The interaction history tables contain transactional data which may grow fast. By using the sample scripts, the users can archive the data in the archiving database and delete (purge) the records from the source database. The scripts allow you to move the FACT table records, merge the Dimension records, and delete the records from the FACT table. Before you use any of the scripts, back up the source and target interaction history tables and create indexes on the columns. Indexes improve performance when you read data from the archived tables.
- Applying interaction history scripts in Oracle databases
Use interaction history scripts with Oracle databases to archive or purge the interaction history tables on Windows OS. The scripts allow you to move the FACT table records, merge the Dimension records, and delete the records from the FACT table.
