Hi We have one materialized view (ABC) which was configured to be refreshed on DEMAND.This ABC will be refreshed at the end of the day by using one procedure.There is one more count MV (ABC_COUNT) which configured to be refresh ON COMMIT; When the refresh was happening,first its deleting the total data from MV and re populating the fresh data. There are some others jobs are executing the at the same time which depends on the same MV few times it leads to missing of some records. In order to resolve this issue I want to depend on the ABC_COUNT mv to get the exact count. Here my question was what will be the result of the ABC_COUNT mv when the actual ABC mv refresh was happening? Is there any change to get the ZERO count just like ZERO results in MV ?
