FetchRow Method
The FetchRow method sets the current row in the cache to the row specified in the rowindex parameter. The data stream must have been opened in QY_CACHE mode.
This method has the following syntax:
integer = DataStream.FetchRow(rowindex = integer)
After the FetchRow method is executed, the NextRow method retrieves the row at rowindex + 1 (if these are valid row numbers), and the PrevRow method positions the data stream at rowindex - 1. FetchRow(rowindex = 0) can be used to rewind the data stream to a position immediately before the first row (as if the data stream had just been opened).
If the FetchRow method is successful, it returns ER_OK. If it is not successful, it returns an error status. Descriptions of system constant values and their numeric equivalents are listed in
Error Codes.
