将行集变量转换为标量变量 [英] Convert Rowset variable to scalar variable

问题描述

我有一个行集变量，它正在提取一个csv文件，其中包含一列，其中包含DLS中存在的不同文件的路径.现在，我必须将此行集变量用作可在EXTRACT表达式的FROM子句中使用的标量变量.

I have a rowset variable that is extracting a csv file, which contains a single column containing paths for different files present in DLS. Now I have to use this rowset variable as a scalar variable that can be used in FROM clause of EXTRACT expression.

请帮助我！
