DwUpdateWhere Enum

.NET Standard 2.x | Current Version (1.0.1)

0.5.0-alpha 1.0.1 (current)

Represents the type of the action executed on the row.

It indicates which columns will be included in the WHERE clause of the UPDATE statement.

0 -- Key columns only (risk of overwriting other users' change, but fast).

1 -- Key columns and all updatable columns (risk of preventing valid updates; slow because SELECT statement is longer).

2 -- Key and modified columns (faster and allows more valid updates than 1, but not as fast as 0).
