what would be the simplest logic you would use to accomplish the following:
tableMatch is the matching table, it gives the new values for an old value that must be replaced with a logic in 4 following tables. The steps involved are: *insert another record into tableA with a new PK and replace the new value, and copy the rest of the data. *do the same concept with tableB also *insert another records in tableC with a new PK, and get the new PK from tableB and keep as FK and get the rest of the values *the only key in tableD is tableC_FK, so just insert a new record with the new tableC_PK reference and get the new value there also and get the rest of the data..
Assume, there will be 1000s of records like this that the logic has to run against.... thanks 
tableMatch  OldVal,NewVal 12234,94223
tableA  PK,'values' A1,12234,1,2,3 tableB  PK,tableA_FK,'values' B1,12234,4,5,6
tableC  PK, tableB_FK,'values' C1,B1,7,8,9
tableD  tableC_PK,'values' C1,12234,11,12  After the DMLs tableMatch  OldVal,NewVal 12234,94223
tableA  PK,'values' A1,12234,1,2,3 A2,94223,1,2,3 tableB  PK,tableA_FK,'values' B1,12234,4,5,6 B2,94223,4,5,6
tableC  PK, tableB_FK,'values' C1,B1,7,8,9 C2,B2,7,8,9
tableD  tableC_PK,'values' C1,12234,11,12 C2,94223,11,12
