DefaultValues

Used for TOraDataSet to fill the DefaultExpression property of TField objects by appropriate value.

DeferredLobRead

Used to fetch all Oracle 8 Lob values when they are explicitly requested.

DetailDelay (inherited from TDADataSetOptions)

Used to get or set a delay in milliseconds before refreshing detail dataset while navigating master dataset.

EnableBCD

Used to enable currency type. Default value of this option is False.

EnableFMTBCD

Used to enable using FMTBCD instead of float for large integer numbers to keep precision.

ExtendedFieldsInfo

Used to perform an additional query to get information about returned fields and the tables they belong to.

FieldsAsString

Used to treat all non-BLOB fields as being of string datatype.

FieldsOrigin (inherited from TDADataSetOptions)

Used for TCustomDADataSet to fill the Origin property of the TField objects by appropriate value when opening a dataset.

FlatBuffers (inherited from TDADataSetOptions)

Used to control how a dataset treats data of the ftString and ftVarBytes fields.

FullRefresh

Used to refresh fields of all tables by the RefreshRecord method.

HideRowId (inherited from TOraDataSetOptionsDS)

Used to display the ROWID column.

Used for TCustomDADataSet to use local filtering to establish master/detail relationship for detail dataset and does not refer to the server.

LongStrings (inherited from TDADataSetOptions)

Used to represent string fields with the length that is greater than 255 as TStringField.

MasterFieldsNullable (inherited from TDADataSetOptions)

Allows to use NULL values in the fields by which the relation is built, when generating the query for the Detail tables (when this option is enabled, the performance can get worse).

NumberRange (inherited from TDADataSetOptions)

Used to set the MaxValue and MinValue properties of TIntegerField and TFloatField to appropriate values.

PrefetchLobSize

Used to retrieve the LOB length and the LOB data beginning during regular fetch.

PrefetchRows

Used to set the number of rows to be prefetched during the execution of a query.

PrepareUpdateSQL

Used to automatically prepare update queries before execution.

ProcNamedParams

Used to specify a notation method of passing parameter values to the stored PL/SQL object.

QueryRecCount (inherited from TDADataSetOptions)

Used for TCustomDADataSet to perform additional query to get the record count for this SELECT, so the RecordCount property reflects the actual number of records.

QuoteNames (inherited from TDADataSetOptions)

Used for TCustomDADataSet to quote all database object names in autogenerated SQL statements such as update SQL.

RawAsString

Used to treat all RAW fields as being of string datatype.

ReflectChangeNotify

Used for a dataset component to refresh its data when it gets database change notification messages in response to DML or DDL changes on the objects associated with the dataset query.

RemoveOnRefresh (inherited from TDADataSetOptions)

Used for a dataset to locally remove a record that can not be found on the server.

RequiredFields (inherited from TDADataSetOptions)

Used for TCustomDADataSet to set the Required property of the TField objects for the NOT NULL fields.

ReturnParams (inherited from TDADataSetOptions)

Used to return the new value of fields to dataset after insert or update.

ScrollableCursor

Used for TOraDataSet to use scrollable server cursor (available since Oracle 9 only) instead of caching data on the client side.

SetFieldsReadOnly (inherited from TDADataSetOptions)

Used for a dataset to set the ReadOnly property to True for all fields that do not belong to UpdatingTable or can not be updated.

StatementCache

Used to get a value indicating whether Oracle resources assosiated with the current statement will be cached inside a session.

StrictUpdate (inherited from TDADataSetOptions)

Used for TCustomDADataSet to raise an exception when the number of updated or deleted records is not equal 1.

TemporaryLobUpdate

Temporary LOBs are used to write input and input/output LOB parameters into database when executing dataset's SQL statements.

TrimFixedChar (inherited from TDADataSetOptions)

Specifies whether to discard all trailing spaces in the string fields of a dataset.
