SQL包查询

我在postgreSQL数据库中有一个地块表，需要查询特定地块。3个字段-门、街区、地块

mun1: block 46 and lot 2

mun2: block 1 and lot 1.1
      block 2 and lot 6
      block 2 and lot 7
      block 5 and lot 2
      block 11 and lot 1

mun3: block 11 and lot 2
      block 11 and lot 2.2
      block 7 and lot 2
      block 8 and lot 2

我可以一次查询每一个，但我不知道如何在一个查询中完成它们……有没有语法和逻辑方面的建议

例：

像这样的

select * from parcels 
where (mun = 'mun1' and block = '46' and lot = '2')
or (mun = 'mun2' and
    (block = '1' and lot = '1.1'
    or block = '2' and lot = '6'
    or block = '2' and lot = '7'
    or block = '5' and lot = '2'
    or block = '11' and lot = '1'
     )
)
or (mun = 'mun3' and 
    (block = '11' and lot = '2'
     or block = '11' and lot = '2.2'
     or block = '7' and lot = '2'
     or block = '8' and lot = '2'
    )
)

你能提供一些样本数据吗？我想你们的问题还不清楚。@GiorgosAltanis check EditOK是的，这就是我想要的逻辑，我将给出一个简单得多的方法，用你们想要的值创建一个临时表/表变量，并进行内部join@MarshallTigerus你愿意分享你的答案吗？

select * from parcels 
where (mun = 'mun1' and block = '46' and lot = '2')
or (mun = 'mun2' and
    (block = '1' and lot = '1.1'
    or block = '2' and lot = '6'
    or block = '2' and lot = '7'
    or block = '5' and lot = '2'
    or block = '11' and lot = '1'
     )
)
or (mun = 'mun3' and 
    (block = '11' and lot = '2'
     or block = '11' and lot = '2.2'
     or block = '7' and lot = '2'
     or block = '8' and lot = '2'
    )
)
