Updating table with values from another table
Without the WHERE clause, rows that do not have a corresponding row in SQL.NEWPOP would have their Population values updated to missing.Because you created the two pivot tables from the same source data, by default they use the same pivot cache, which is where the grouping is stored.
In Step 1 of the Excel 2003 Wizard, you can select the first option, to create an independent pivot table.
etc I have a mapping table where "ALL" old account number and new account numbers are present.
But Sales Supplier, Purchase supplier, Wholesale Supplier ..many other columns how can i update in single SQL ( I have to update around 70 columns and some columns may have null values such as Purchase supplier ..) 2. You need to have the table you are updating from have a unique or primary key constraint.
I want to write SQL ( not PL/SQL ) to update transaction table from mapping table at one stroke. regards & thanks pjp update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.new_account_number ) set old_account_number = new_account_number; disabling foreign keys during the operation and enabling them afterward. update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.old_account_number ) set old_account_number = new_account_number; (ie in the subquery, match the old account numbers not try matching the old in the old table to the new in the mapping table) Of course if the original posting had the CREATEs/INSERTS etc, it would have a quick and east test.
I have to update a transaction table where mapping is existing with old account no and new account number.
