* NAME
* 149. fetchArraySize2.js
*
* DESCRIPTION
* Basic test of fetching data from database with different oracledb.fetchArraySize, oracledb.maxRows, numRows.
* maxRows specifies maximum number of rows that are fetched by the execute() call of the
* Connection object when not using a ResultSet.
* Tests including:
* basic fetch tests with different oracledb.fetchArraySize and oracledb.maxRows.
* REF CURSORS tests with different oracledb.fetchArraySize and numRows.
* QueryStream() tests with different oracledb.fetchArraySize and oracledb.maxRows.
