Question

我有两个访问表和两个连续数字（1057,1045,4252等）我想拉出两个表中的类似记录。例如，如果表x具有记录1057并且表y还包括1057而不是我想要看到那些记录。任何帮助将不胜感激。感谢

Answer 1

select t1.*,t2.* from table1 as t1
inner join table2 as t2 on (t1.COMMONCOLUMNID = t2.COMMONCOLUMNID)

EDITED

select * from TableName where DiscreteUID in (select predecessor from TableName) 
or
DiscreteUID in (select successor from TableName)

EDITED

    (select DiscreteUID, 1 as IsPredecessor, 0 as IsSuccessor from TableName where DiscreteUID in (select predecessor from TableName))

UNION
    (select DiscreteUID, 0 as IsPredecessor, 1 as IsSuccessor from TableName where DiscreteUID in (select successor from TableName))

从两个表中提取类似的记录
