* 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.
