* NAME
|
|
* 152. fetchArraySize5.js
|
|
*
|
|
* DESCRIPTION
|
|
* Basic test of fetching data from database with different execute() option
|
|
* fetchArraySize, oracledb.maxRows, and 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 fetchArraySize and oracledb.maxRows.
|
|
* REF CURSORS tests with different fetchArraySize and numRows.
|
|
* QueryStream() tests with different fetchArraySize and oracledb.maxRows.
