Par2: Oracle views and errorcode 47
2000-05-31 -- Bruce Wells
 
Clarion ignores any fields in the Oracle table that are not defined in the Clarion dictionary so it is not possible to get an error 47 by missing one or more of the Oracle columns. However, all columns from the primary key (on the Oracle side) must be in the Clarion dictionary and the Clarion primary key fields must exactly match the Oracle primary key fields. If the developer is allowing updating of the data files combined in the view, Oracle only allows one of these tables to be updated. If this update is allowed, all of the primary key columns, for the table to be updated, must be in the Oracle view. If there is a data type mismatch between Clarion and SQL that an error 47 will result. Therefore if, after the synchronization, the developer changed the Clarion data types from the ones selected during the sync an error 47 will occur. The external name in the Clarion dictionary is only necessary if the Clarion field name is changed. Our naming convention on the Oracle side is set for the advantage of the DBAs so that all columns can be identified and associated with a schema. We change this naming in Clarion to make the program more readable. If we didn't do that the external name would not be needed. This is another question to ask the developer.
