Aurora：基于主键查找两个表之间的差异

Question

我有下面的TABLE1

|001000900|aaaaa BELLOWS CORPORATION||N|
|001000905|ddddd DEPARTMENT OF LABOR AND EMPLOYMENT SECURITY|BUREAU OF COMPLIANCE|N|
|001001049|gggg RAVIOLI MFG CO INC|SPINELLI BKY RAVIOLI PASTRY SP|N|

|001001184|TRILLION CORPORATION||N|
|001001192|HAWAII STATE CHIROPRACTIC ASSOCIATION INC||N|
|001001379|THE FRUIT SQUARE PEOPLE INC|L & M BAKERY|N|
|001001416|J & S MARKET||N|

像这样的Table2

|001000145|PARADISE TAN||N|
|001000306|SHRUT & ASCH LEATHER COMPANY, INC.||N|
|001000355|HARRISON SPECIALTY CO., INC.||N|

|001000504|DIRIGO SPICE CORPORATION|CUNNINGHAM SPICE|N|
|001000744|FREEDMAN THREAD COMPANY|COLONIAL THREAD CO|N|
|001000756|AFFORDABLE AIR CONDITIONING|P R ENTERPRISE|N|
|001000900|CLIFLEX BELLOWS CORPORATION||N|
|001000905|FLORIDA DEPARTMENT OF LABOR AND EMPLOYMENT SECURITY|BUREAU OF COMPLIANCE|N|
|001001049|SPINELLI RAVIOLI MFG CO INC|SPINELLI BKY RAVIOLI PASTRY SP|N|
|001001130|LOS ANGELES UNIFIED SCHOOL DISTRICT|TRANSPORTATION BRANCH|N|
|001001143|TOSCO MUSIC PARTIES, INC||N|
|001001155|BOSTON BRASS AND IRON CO||N|

我的要求是，仅当主键（其他行更改）时，才基于第一列查找两个表（匹配行）中都存在的行。

例如，如果主键相同，而它们的其他列至少不同，则它将出现在输出中。

我该怎么做。 平原会给我结果吗？

Answer 1

您是否正在寻找具有join条件的where？

select t1.*, t2.*
from table1 t1 join
     table2 t2
     on t1.pk = t2.pk
where not (t1.col2 <=> t2.col2) or
      not (t1.col3 <=> t2.col3) or
      not (t1.col4 <=> t2.col4) ;
