Description

Put data from a recordset into an Origin Matrix

Syntax

BOOL PutRecordset( Object & objrs, int nMaxNumFields = -1, int nMaxNumRecords = -1, int nBufferSize = 10 )

Parameters

objrs: [input]recordset to take the data from.
nMaxNumFields: [input]maximum number of fields (columns) to get, or -1 to get all.
nMaxNumRecords: [input]maximum number of records (rows) to get, or -1 to get all.
nBufferSize: [input]how many rows will be read from recordset each time, this size is the value of nrows when call GetRows method inside this method.

Return

Returns TRUE on success or FALSE on failure.
