Oracle 在SHELL中迭代PL/SQL结果
我想在SHELL脚本中迭代PL/SQL行，并且对于每一行，我想使用当前行执行一些代码。在这一点上，我得到：Oracle 在SHELL中迭代PL/SQL结果,oracle,shell,unix,Oracle,Shell,Unix,我想在SHELL脚本中迭代PL/SQL行，并且对于每一行，我想使用当前行执行一些代码。在这一点上，我得到： VALUE='sqlplus -s /nolog <<EOF CONNECT ${CONNECT} select smth from table; / EXIT EOF' for i in "${VALUE[@]}" do ##some code using "i" variable done
VALUE='sqlplus -s /nolog <<EOF
CONNECT ${CONNECT}
select smth from table;

for i in "${VALUE[@]}"
do
##some code using "i" variable
done
VALUE='sqlplus-s/nolog您可以按如下方式迭代结果集：

set head off
select car_model from available_models
group by car_model

echo "now iterate ..."
let rec=0
echo "${VALUE}" |while read line
do
echo "processing $rec: $line"
let rec=rec+1
done

重写shell脚本（使用WHILE），如下所示：

2 group by car_model ;

请注意，第#0行为空，应为空，因为它也是结果集的一部分
添加“设置页面大小0”将删除此空行：

set head off
set pagesize 0
