sql - How do I check if a table have matching record in another table? -


मैं टेबल निम्नलिखित:

तालिका 1: AccessMenu 

  उपयोगकर्ता आईडी 1 ए 2 बी 2 सी   
 और  
  तालिका 2:  ActionRights    
  idAdmin itemCol 2 वी 2 मीटर 2 घ   
  वांछित परिणाम:   <आईडी> <आईडी> <आईडी> <आईडी> <आईडी> <आईडी>  कोड> ActionRight  इसे वापस चाहिए  हां  अन्यथा  नहीं   
 मैं क्वेरी के नीचे की कोशिश की:।  
  AccessMenu.userid, मामले का चयन जब ActionRights.IdAdmin = AccessMenu.userid तो 'हाँ' और कुछ 'नहीं' AccessMenu से 'जीआरपी' के रूप में अंत ActionRights.IdAdmin = AccessMenu.userid पर ActionRights में शामिल होने के लिए छोड़ दिया   
 लेकिन इस प्रश्न के माध्यम से मुझे बार-बार परिणाम मिल रहा है:  
  यूजर आईडी हाँ / नहीं 1 नहीं 2 हाँ 2 हाँ 2 हाँ 2 हाँ 2 हाँ   <पी> कृपया मेरी मदद करो।   
 
 
 <कोड> का चयन करें userid, मामला है जब idadmin शून्य फिर से 'नहीं' शेष 'हाँ' अंत के रूप में 'समूह' है (accessmenu.userid प्रयोक्ता-आईडी के रूप में चयन, actionrights.idadmin IdAdmin रूप से Accessmenu LEFT कार्यवाही को क्रियान्वित करने के लिए एक्शनआरइट.आईडडमिन = एक्सेसमेन्यू। यूज़र), z

If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon.
