v_SendID:=substr(v_SendID,v_FirstPoint+1,v_lenth);
substr错误:
Line # = 13 Column # = 1 Error Text = PLS-00363: expression 'V_SENDID ' cannot be used as an assignment target
Line # = 13 Column # = 1 Error Text = PL/SQL: Statement ignored
搞了半天不知怎么解决,麻烦各位帮一下忙.


------解决方法--------------------------------------------------------
v_SendID是个input类型参数吧？imput类型的参数是不允许更改的。
