 * NAME
 *   63. autoCommit4nestedExecutes.js
 *
 * DESCRIPTION
 *   Nested executes where the 2nd execute fails used to cause an unexpected
 *   commit, even though the autoCommit:false setting is enabled at the
 *   execute() and/or oracledb level. This is github issue 269. It has
 *   been fixed in 1.4.
 *
 *   https://github.com/oracle/node-oracledb/issues/269
