MssqlAffectedRowsSource enum

Where an affected-row count came from, so a caller can judge it.

The driver's own affectedRows is the sum of every row-count token the batch produced, which on a table with a trigger includes the trigger body's own writes. That number answers "how much did the server do", not "how many of my rows changed", and the two are routinely different.

Values

outputRows → const MssqlAffectedRowsSource

Counted from the rows the statement's own OUTPUT clause produced. Exact: those rows are the rows the statement wrote.

immediateRowCount → const MssqlAffectedRowsSource

SELECT @@ROWCOUNT in the same batch, immediately after the statement. Exact only when no trigger ran, which is why it is used only then.

singleRowStatement → const MssqlAffectedRowsSource

A single-row statement that did not throw, so it wrote its one row.

driverTotal → const MssqlAffectedRowsSource

The driver's batch total, with no way to attribute it. Reported as-is and marked, rather than dressed up as a per-statement count.
