SQLException

setAutoCommit

void setAutoCommit(boolean autoCommit)
            throws SQLFeatureNotSupportedException,
                   SQLException

Drill: Accepts only true.

Specified by:

setAutoCommit in interface Connection

Throws:

SQLFeatureNotSupportedException - if called with false

                             SQLException

Drill: Accepts only Connection.TRANSACTION_NONE.

Specified by:

setTransactionIsolation in interface Connection

Throws:

SQLFeatureNotSupportedException - if level is not Connection.TRANSACTION_NONE.

SQLException
