DBMS_RECTIFIER_DIFF.RECTIFY

Synopsis

The DIFFERENCES procedure paves the way for its companion procedure, RECTIFY, which synchronizes the reference table (oname1). Before running the RECTIFY procedure, always make sure that the updates to the comparison table (oname2) will not violate any integrity, check, or NOT NULL constraints. Note that this procedure does not modify the reference table.

The DIFFERENCES and RECTIFY procedures can take a long time to run. If the volume of data is significant, it will probably be easier for you to simply reinstantiate the comparison table byimportingan export of the reference table.

PROCEDURE DBMS_RECTIFIER_DIFF.RECTIFY
   (sname1 IN VARCHAR2,
   oname1 IN VARCHAR2,
   reference_site IN VARCHAR2 := '',
   sname2 IN VARCHAR2,
   oname2 IN VARCHAR2,
   comparison_site IN VARCHAR2 := '',
   {column_list IN VARCHAR2 := '' |
   array_columns IN dbms_utility.name_array},
   missing_rows_sname IN VARCHAR2,
   missing_rows_oname1 IN VARCHAR2,
   missing_rows_oname2 IN VARCHAR2,
   missing_rows_site IN VARCHAR2 := '',
   commit_rows IN INTEGER := 500);
