We did try this method, but it didn't work. The error was due to the presence of foreign key in the referencing tables, therefore the 'deleted' 'tmp table' cannot be created in the first place, i.e. no deletion on the referenced table (with primary key) can be performed, until all the records in the referencing tables are removed.<br />

You can't have both. You either use REFERENCES constraint or do all referencial integrity enforcement by using triggers: you have to create INSERT, DELETE and UPDATE triggers instead of REFERENCSES. Or &nbsp;you can implement it in your application. In this case all delete operations should be done only through your application<br />

Since, the records in the referencing tables must be deleted first before those in the referenced table. Could someone provide some advices.
