Should primary key fields be marked pfInKey
Source position: sqldb.pp line 678
published property TSQLQuery.UsePrimaryKeyAsKey : Boolean; |
UsePrimaryKeyAsKey can be set to True to let TSQLQuery fetch all server indexes and if there is a primary key, update the ProviderFlags of the fields in the primary key with pfInKey.
The effect of this is that when UpdateMode equals upWhereKeyOnly, then only the fields that are part of the primary key of the table will be used in the update statements. For more information, see UpdateSQLs.
Note that this property only takes effect if the fields are the default fields: if persistent fields were created, the providerflags of the fields are not updated.
