Prepares to update the current row in this table.

Syntax

updateBegin()

Remarks

Column values are modified by calling the appropriate setType method or methods.

The data in the row is not actually changed until you execute the update, and that change is not permanent until it is committed.

Modifying columns in the index used to open the table will affect any active searches in unpredictable ways. Columns in the primary key of the table can not be updated.
