Google bigquery BigQuery-使用两个字段提取REGEXP

我有一个包含三个字段的表：

Ref Alt INFO

A   T       SNP;FN1,DKFZp686O22169;DKFZp686O22169(uc002vez.2)///FN1(uc010zjp.1)///FN1(uc002vfa.2)///FN1(uc002vfb.2)///FN1(uc002vfc.2)///FN1(uc002vfd.2)///FN1(uc002vfe.2)///FN1(uc002vff.2)///FN1(uc002vfg.2)///FN1(uc002vfh.2)///FN1(uc002vfi.2)///FN1(uc002vfj.2)///FN1(uc010fvc.1)///FN1(uc010fvd.1);Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding;5UTR///Intron_8///Intron_32///Intron_31///Intron_31///Intron_32///Intron_31///Intron_31///Intron_31///Intron_31///Intron_32///Intron_32///Intron_2///Intron_2;.///.///.///.///.///.///.///.///.///.///.///.///.///.;.///.///.///.///.///.///.///.///.///.///.///.///.///.;A-0.9491,T-0.0509;A-970,T-52;A/A-0.9002,A/T-0.0978,T/T-0.0020;A/A-460,A/T-50,T/T-1,N/N-0

我是否可以使用前两个字段从

INFO

字段中提取

A/T-0.0978

谢谢

下面是BigQuery标准SQL，并提取给定组合的所有值（在特定示例中为两个）

如果您针对问题中的数据运行它，结果将是

#standardSQL
WITH `project.dataset.table` AS (
  SELECT 'A' Ref, 'T' Alt, 'SNP;FN1,DKFZp686O22169;DKFZp686O22169(uc002vez.2)///FN1(uc010zjp.1)///FN1(uc002vfa.2)///FN1(uc002vfb.2)///FN1(uc002vfc.2)///FN1(uc002vfd.2)///FN1(uc002vfe.2)///FN1(uc002vff.2)///FN1(uc002vfg.2)///FN1(uc002vfh.2)///FN1(uc002vfi.2)///FN1(uc002vfj.2)///FN1(uc010fvc.1)///FN1(uc010fvd.1);Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding///Protein_Coding;5UTR///Intron_8///Intron_32///Intron_31///Intron_31///Intron_32///Intron_31///Intron_31///Intron_31///Intron_31///Intron_32///Intron_32///Intron_2///Intron_2;.///.///.///.///.///.///.///.///.///.///.///.///.///.;.///.///.///.///.///.///.///.///.///.///.///.///.///.;A-0.9491,T-0.0509;A-970,T-52;A/A-0.9002,A/T-0.0978,T/T-0.0020;A/A-460,A/T-50,T/T-1,N/N-0' INFO
)
SELECT REGEXP_EXTRACT_ALL(INFO, CONCAT(r'[,;](', Ref, '/', Alt, '.*?)[,;]')) val
FROM `project.dataset.table`   

有输出

Row     val  
1       A/T-0.0978   
        A/T-50   

如果您想要第一个值，您可以使用

#standardSQL
SELECT REGEXP_EXTRACT_ALL(INFO, CONCAT(r'[,;](', Ref, '/', Alt, '.*?)[,;]'))[OFFSET(0)] val 
FROM `project.dataset.table`
