findRow

Finds a row and repositions it using a key.

Location: data.p

INPUT pcKeyValues AS CHARACTER

Comma- or chr(1)-separated list of keyfields.

Returns: LOGICAL

Notes:

This method resolves the row reposition on the server. As a result, the SDO can no longer determine whether the row position is invalid until after the request has been executed. However, if the RebuildOnRepos property is set to TRUE, the temp-table is emptied before the request.
The current behavior for a FIND that does not find anything when RebuildOnRepos is TRUE is to read the current batch again.
