主要用max，decode函数

Select province_name,Province_Code,Report_Id,
MAX(decode(N1, 1, s2, NULL)) s2,
MAX(decode(N1, 1, n2, NULL)) n2,
Max(Decode(N1, 1, N3, Null)) N3,

Max(Decode(N1, 2, N2, Null)) "n2-1",
Max(Decode(N1, 2, N3, Null)) "n3-1",
Max(Decode(N1, 2, N4, Null)) "n4-1",
Max(Decode(N1, 3, S2, Null)) "s2-2",
Max(Decode(N1, 3, S3, Null)) "s3-2"
