如何在批處理腳本中添加while循環以檢查給定次數嘗試的狀態

Question

我有一個 tabadmin refreshextract 腳本，它工作正常，但現在我們想從 airflow 實現它，唯一的問題是如果 session 重新連接，然后 Z2528F15A184A14D75D2E092E3Z 成功刷新日志，但最終它成功了。

我們添加了 psql 查詢來查找，一旦刷新提取完成，它將提取成功或失敗的信息。

tabcmd refreshextracts --url workbook_url -s https:// -t site -u tabadmin --password-file C:\Users\abc\Desktop\passwd.txt --no-certcheck

偽代碼

cd c:\Program Files\PostgreSQL\11\bin
refresh_status='N'
retry_count = 0
while refresh_status = 'N' and retry_count < 20
retry_count++
refresh_status = $(psql -p 8060 -h servername -U readonly -d workgroup -c " select case when lower(notes) like '%finished%'  == 'succeed' then 'Y' else 'N" as refresh_status from _background_tasks where Job_name = 'Refresh Extracts' and title = 'workbook_name'  and  created_at >=CURRENT_DATE ORDER BY created_at desc limit 1")
if refresh_status == 'Y'
    EXIT Success
else
    continue
continue
if refresh_status = 'N'
    exit ERROR

這應該工作

@echo off
set attempts=0
:loop
set /a attempts+=1
if %attempts%==5 (echo %attempts%)
goto loop

或這個

@echo off
set attempts=0
:loop
set /a attempts+=1
echo %attempts%
goto loop

順便說一句，這些都是例子。
