mysql - Update table with data from secondary table by foreignkey -


मेरे पास दो टेबल हैं: tableA और tableB । मैं tableB को निकालना चाहता हूं, इसलिए यह बेमानी है, इसलिए मुझे कॉलम मूल्यों को tableB से tableA कॉपी करना होगा।

टेबल ए: <पूर्व> | आईडी | नाम | टेबलए_आईडी |

तालिका B 

  | आईडी | टेबल सी_आईडी | टेबल डी_आईडी |   
  tableA  बदल दिया गया है, इसलिए इसमें अतिरिक्त कॉलम हैं  tableA :  
  | आईडी | नाम | टेबलए_आईडी | टेबल सी_आईडी | टेबल डी_आईडी |   
 तो मूल रूप से मैं कॉलम  tableB.tableC_id  और  tableB.tableD_id  में  tableA.tableC_id  और  tableA.tableD_id ।  
 कैसे मैं एक एसक्यूएल अद्यतन में इसे बंद खींच सकते हैं?   
 
 
 आप अपडेट के साथ अपडेट करते हैं ; -)  
  सारणी सारणी में एक टेबल पर शामिल होने के लिए TableB.id = tableB.id सेट तालिका A.tableC_id = tableB.tableC_id, tableA.tableD_id = tableB.tableD_id;
