Question

有人可以告诉我我在set flag1做错了什么..我收到了flag1的错误：未定义的变量。

if($notLoaded1 > 0) then
  echo "Rows not loaded due to data errors in first load: $notLoaded1"
  set flag1=1
endif

if($notLoaded2 > 0) then
  echo "Rows not loaded due to data errors in second load: $notLoaded2"
  set flag2=1
endif

if($notLoaded3 > 0) then
  echo "Rows not loaded due to data errors in third load: $notLoaded3"
  set flag3=1
endif

echo $flag1
echo $flag2
echo $flag3

有没有办法在一个if语句中检查所有三个，而不是使用3个if语句

if ($flag1 > 0) then
  exit 1
endif

if ($flag2 > 0) then
  exit 1
endif

if ($flag3 > 0) then
  exit 1
endif

谢谢

Answer 1

只有flag1大于0才会设置

$notLoaded1。因此，如果它为零，则不会获得$ flag1。

我建议事先用默认值初始化这三个变量：

set flag1=0
if (...) the
    set flag1=1
    echo 'Rows not loaded...'
endif

这将保证flag1始终存在。

Answer 2

你需要3个标志变量？

set error=0

if ($notLoaded1 > 0) then
  echo "Rows not loaded due to data errors in first load: $notLoaded1"
  set error=1
endif

if ($notLoaded2 > 0) then
  echo "Rows not loaded due to data errors in second load: $notLoaded2"
  set error=1
endif

if ($notLoaded3 > 0) then
  echo "Rows not loaded due to data errors in third load: $notLoaded3"
  set error=1
endif

if ($error) then
  exit 1
endif
