property GettingMethod: TGettingMethod;

Determine how data are retrived from engine. See also TGettingMethod.

property ObjectView;

property OnCalcFields;

property OnDeleteError;

property OnEditError;

property OnNewRecord;

property OnPostError;

property ReadOnly: Boolean;

property RecNo;

property RecordCount;

property RecordSize;

property SLOptions: TSLOptions;

Options - see TSLOptions.

property SQL: TStrings;

property State;

property Tail: String;

Used when GettingMethod = gmVMachine. When SQLite compiles SQL to virtual machine only first statement is taken. Rest of query can be found here.
With ohter getting methods Tail property has no meaning.

property UpdatingFieldNames: String;

Define fields that will be taken for update/insert. Not done yet.

property UpdatingTableName: String;

Name of updating table. If no name set, by default name of first table will be taken
