我有以下使用BTEQ執行Teradata存儲過程的shell腳本。存儲過程返回一個名爲BATCH_KEY的varchar。您能否解釋如何:在Teradata BTEQ腳本中捕獲存儲過程輸出
捕獲存儲過程的輸出在BTEQ腳本中?將輸出傳遞給shell腳本?讓shell腳本自己返回輸出值?
echo "Check if number of parameters is correct"
if [ "$#" -ne 4 ]; then
echo "You must enter exactly 4 command line arguments"
exit 0
fi
echo "Call bash profile"
source ~/.bash_profile
echo "Setting parameters value for the stored procedure"
in_P_BATCH_OWNER=$1
in_P_ACTION=$2
in_P_START_DATETIME=$3
in_P_END_DATETIME=$4
echo "Logging into Teradata"
Server=server
LoginId=user
Password=password
DbName=db
echo "Calling stored procedure"
bteq<<EOF
.logon ${Server}/${LoginId},${Password};
CALL $DbName.SP_AUDIT_BATCH('$in_P_BATCH_OWNER', '$in_P_ACTION', '$in_P_START_DATETIME', '$in_P_END_DATETIME');
.logoff;
.quit;
EOF
if [ $? == 0 ]
then
echo "Script executed sucessfully"
exit 1
else
echo "Script executed with failure"
exit 0
