mysql - WHERE statement after a UNION in SQL? -

-

मैं SQL / MySQL में एक यूनियन के बाद WHERE कथन को कैसे लागू करूं?

यदि आप UNION के परिणामस्वरूप WHERE क्लास को लागू करना चाहते हैं, तो आपको एम्बेड करना होगा एफआरएम खंड में यूनियन: 

  SELECT * FROM (सेलेब्रिबल संघ चुनिए * टेबलबैक से चयन करें) यूके यू.कॉल 1 = ...   
 मैं TableA मान रहा हूँ और TableB संघ-संगत हैं। आप यूनिअन में प्रत्येक व्यक्तिगत SELECT कथन के लिए एक WHERE क्लॉज़ भी लागू कर सकते हैं, बेशक।
