如何在Teradata中捕获DML的输出？

Question

我想要将Teradata DML查询的输出捕获到存储过程中的变量中。例如：

delete from emp; 

我希望删除记录的数量进入可用于记录目的的变量。

Answer 1

您是否阅读过手册？

有旧式ACTIVITY_COUNT

declare cnt int; 
delete from emp; 
set cnt = activity_count; 

和标准SQL的GET DIAGNOSTIC

declare cnt int; 
delete from emp; 
get diagnostics cnt = row_count;
