GetRows - method of the AdoRecordset object

Description:

Copies multiple records of the AdoRecordset object into an 2-dimensional array.

Syntax:

Array GetRows([Long nRows], [Variant vStart], [Variant aFields])

Parameters:

nRows	[optional] (Long) Specifies the number of returned records. The default value is -1 = (adGetRowsRest) all remaining records.
vStart	[optional] (Variant) Specifies the starting position (Bookmark). If not set, then the starting position will be the position of the current record. If a valid Bookmark is defined, then it will be used as starting position. It is also possible to use standard numeric constants for specifying the start position: 0 (default) - (adBookmarkCurrent) Current record. 1 - (adBookmarkFirst) First record. 2 - (adBookmarkLast) Last record.
aFields	[optional] (Variant) A single name, or an array of column names or ordinal positions of the fields in the record.

Return value:

Returns 2-dimensional array (PmArray object for JavaScript or Array data type for VBScript).

Example1:

Reading the data as 2-dimensional array. Request for the first 20 records of all columns from the current record (first record) position.

var oDb = pMe.Pm("/TestAdoDb");

var oRs = oDb.RsOpen("", "SELECT * FROM table1", "cursor:static;");

var aData = Pm.CreatePmArray();

if (oRs)

{

	oRs.MoveFirst();

	aData.LoadFromVbArray(oRs.GetRows(20, 0));

}

Example2:

Reading the data as 2-dimensional array in the PmaAdo object ("/TestAdoDb"), that is connected to the database (see the DbOpen method), using the SQL query ("SELECT * FROM table1"). The resulting AdoRecordset object will be stored in the PmaAdo object with an unique identifier ("table1"), as (static) and (readonly). It is tested whether no error occurs and a valid AdoRecordset object was returned. The first 20 records from the current record (first record) position are requested with two columns ("name", "value").
