How do INSERT INTO Firebird, with autoincrement for the primary key?

For the table fields I have:

fstPriority VARCHAR(30), fstInfo VARCHAR(100), fstD

Definitions:

public const string stMAIN_TABLE_NAME = " OrgTable ";
public const string stDELETED_TABLE_NAME = "  BackupTable ";

public const string stFIELD_DEFINITIONS = " fstPriority VARCHAR(30)" + 
                                          ", fstInfo VARCHAR(100)" +
                                          ", fstDateCreated VARCHAR(30)" +
                                          ", fstDateModified VARCHAR(30)" +
                                          ", fiKeyID INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY ";
public const string stFIELD_NAMES = " fstPriority" + 
                                    ", fstInfo" + 
                                    ", fstDateCreated" + 
                                    ", fstDateModified" + 
                                    ", fiKeyID ";
public const string stFIELD_NAMES_NO_KEY_ID = " fstPriority" + 
                                              ", fstInfo" + 
                                              ", fstDateCreated" + 
                                              ", fstDateModified ";
