pr_other table

The pr_other table is the default destination for saved instances that belong to a class that is not mapped to any other table. To access the pr_other table, the system uses the catalog and schema specified for the pr4_base table as identified in the databases/baseTable/catalog and databases/baseTable/schema entries in the prconfig.xml file or dynamic system settings.

Each time an object is saved to the pr_other table, the system adds a PEGA0041 alert to the alert log.

This table is convenient during development, as changes to the class structure do not require changes to the database schema. However, use this facility with caution. Because the pr_other table has only a few columns, most properties are stored in the Storage Stream column of this table. Accordingly, accesses to this table — reads, updates, or deletes — are often slower than accesses to the same instance when stored as a row in a "purpose built" table.

Using pr_other to store data for an application under development does not by itself indicate an error in the database design or operations. However, using the pr_other table is undesirable if your application frequently searches rows of this table. In this case, define a new table in the Pega Platform database to hold instances of the class, and add a database table instance to map instances to the new table map saved instances to an existing table.
