BigQuery Join On - 错误：意外

Question

我反复得到

Error: Unexpected. Please try again.

使用此查询：

SELECT Pollen.start, DNase.start, DNase.DNasecleavage
FROM   DNAse_raw_seq.DNAse_raw_seq_Chr1_table AS DNase
JOIN   DNAse_raw_seq.polleninput AS Pollen
       ON DNase.start  = Pollen.start
       where Pollen.GeneID contains "At1";

昨天我在类似的table2上使用了相同的查询，工作正常。 谢谢你的任何建议！

Answer 1

知道了！

正常运行的查询如下所示

SELECT Pollen.GeneID, Pollen.start, DNase.DNasecleavage
FROM   DNAse_raw_seq.DNAse_raw_seq_Chr1_table AS DNase
JOIN   DNAse_raw_seq.polleninput AS Pollen
       ON DNase.start = Pollen.start
       where Pollen.GeneID contains "At1";

我不被允许选择DNase.start ....

Answer 2

SELECT Pollen.start, DNase.start, DNase.DNasecleavage
FROM   DNAse_raw_seq.DNAse_raw_seq_Chr1_table AS DNase
JOIN   DNAse_raw_seq.polleninput AS Pollen
       ON DNase.start  = Pollen.start
       where Pollen.GeneID contains "At1";

你想在“Pollen.GeneID”上使用哪里，但你没有选择它。 您可以通过将其添加到选择来修复它。像这样：

SELECT Pollen.GeneID, Pollen.start, DNase.start, DNase.DNasecleavage
FROM   DNAse_raw_seq.DNAse_raw_seq_Chr1_table AS DNase
JOIN   DNAse_raw_seq.polleninput AS Pollen
       ON DNase.start  = Pollen.start
       where Pollen.GeneID contains "At1";
