A transaction processing method and system, and a server. The method includes: after a first node obtains at least one statement corresponding to a first transaction, the first node may classify each statement, and send the at least one statement to at least one second node according to the type of each statement, respectively, so that the at least one second node generates an execution plan corresponding to the received statement according to the statement; then the first node may process the first transaction according to the received execution plan which corresponds to the at least one statement of the first transaction and is sent by the at least one second node. In this way, embodiments can process statements of multiple types at the same time, thereby effectively improving the processing efficiency of the system, reducing the operating burden of the system, and ensuring the transactionality of the system.
