Executes the given statements atomically. Only works if no other statements are sent through this adapter in parallel! Only use for single-threaded applications, otherwise side effects may happen as this changes the auto commit settings of the connection temporarily.

Parameters:

queries - The queries to execute atomically

Throws:

java.sql.SQLException - If the status of the connection cannot be changed. If something goes wrong while executing the given statements, they are rolled back before they are committed.

close

public void close()

Close the connection. No more queries can be sent after having the access object closed

Specified by:

close in interface java.lang.AutoCloseable

getDriver

public java.lang.String getDriver()
