Name	Description
AutoPrepare (inherited from TDADataSetOptions)	Used to execute automatic TCustomDADataSet.Prepare on the query execution.
CacheCalcFields (inherited from TDADataSetOptions)	Used to enable caching of the TField.Calculated and TField.Lookup fields.
CompressBlobMode (inherited from TDADataSetOptions)	Used to store values of the BLOB fields in compressed form.
DefaultValues (inherited from TDADataSetOptions)	Used to request default values/expressions from the server and assign them to the DefaultExpression property.
DetailDelay (inherited from TDADataSetOptions)	Used to get or set a delay in milliseconds before refreshing detail dataset while navigating master dataset.
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.
InsertAllSetFields (inherited from TDADataSetOptions)	Used to include all set dataset fields in the generated INSERT statement
LocalMasterDetail (inherited from TDADataSetOptions)	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.
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.
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.
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.
StrictUpdate (inherited from TDADataSetOptions)	Used for TCustomDADataSet to raise an exception when the number of updated or deleted records is not equal 1.
TrimFixedChar (inherited from TDADataSetOptions)	Specifies whether to discard all trailing spaces in the string fields of a dataset.
UpdateAllFields (inherited from TDADataSetOptions)	Used to include all dataset fields in the generated UPDATE and INSERT statements.
UpdateBatchSize (inherited from TDADataSetOptions)	Used to get or set a value that enables or disables batch processing support, and specifies the number of commands that can be executed in a batch.

CacheBlobs	Used to allocate local memory buffer to hold a copy of the large object content.
CursorWithHold	Used to open query in the FetchAll=False mode without transaction.
DeferredBlobRead	Used to fetch values of large objects when they are explicitly requested.
DistinctParams	Used for correct TClientDataSet parameters handling.
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 the returned fields and the tables they belong to.
FullRefresh	Used to specify the fields to include in the automatically generated SQL statement when calling the method.
OIDAsInt	Used to read OID fields as integer values and map these fields to TIntegerField.
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.
