MYSQL_ROW_OFFSET mysql_stmt_row_seek(MYSQL_STMT *stmt, MYSQL_ROW_OFFSET offset)
Sets the row cursor to an arbitrary row in a statement result
set. The offset
value is a row offset that
should be a value returned from
mysql_stmt_row_tell()
or from
mysql_stmt_row_seek()
. This
value is not a row number; if you want to seek to a row within
a result set by number, use
mysql_stmt_data_seek()
instead.
This function requires that the result set structure contains
the entire result of the query, so
mysql_stmt_row_seek()
may be
used only in conjunction with
mysql_stmt_store_result()
.
The previous value of the row cursor. This value may be passed
to a subsequent call to
mysql_stmt_row_seek()
.
