Indicates whether the database server supports transactions.
property TransactionsSupported: LongBool;
__property LongBool TransactionsSupported;
Read TransactionsSupported at runtime to ascertain whether the database server supports transactions. If TransactionsSupported is false, then the BeginTransaction, CommitFreeAndNil, RollbackFreeAndNil, and RollbackIncompleteFreeAndNil methods do nothing. If TransactionsSupported is true, you can use the SQL connection component to manage transactions.
CommitFreeAndNil
RollbackFreeAndNil
RollbackIncompleteFreeAndNil
