* ITFlow - Database update to version 3.5.4 (from 3.5.3)
|
|
* Included by admin/database_updates.php - do not access directly
|
|
*
|
|
* Index transfers.transfer_expense_id - the out side of a transfer. The
|
|
* account ledger (accountLedgerSql(), behind Transactions, its Transfers
|
|
* pill and export, and Reconcile) joins every expense to the transfer it
|
|
* may belong to. With nothing to look it up by, each expense was checked
|
|
* against every transfer - expenses times transfers - which is what made
|
|
* those pages crawl as the books grew. transfer_revenue_id, the in side,
|
|
* has had its index since 2.7.5.
|
|
*
|
|
* Re-runnable: skipped where the index is already there.
