MySQL _在单个查询中检索多个行和列

Question

是Mysql的新手

我想从数据库中检索包含StrainName = M18的所有列，但是收到错误。请帮帮我

SELECT * 

strain.strainName,
feature.contigId,
feature.startPosition,
feature.stopPosition,
feature.orfId,
feature.orfType,
feature.funcClassification,
feature.rastId,
feature.strand 
from feature,strain 
where feature.id=strain.id and strainName='M18';

错误1064（42000）：您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行的'strain.strainName，feature.contigId，feature.startPosition，feature.stopPosition，fe'附近使用正确的语法

Answer 1

您需要在*

之后添加逗号

SELECT  *,                      -- <<====== HERE
        strain.strainName,
        feature.contigId,
        feature.startPosition,
        feature.stopPosition,
        feature.orfId,
        feature.orfType,
        feature.funcClassification,
        feature.rastId,
        feature.strand 
from    feature,strain 
where   feature.id=strain.id and 
        strainName='M18';

Answer 2

获取所有列：

SELECT * from feature,strain 
where feature.id=strain.id and strainName='M18';   

获取特定列：

SELECT                       
        strain.strainName,
        feature.contigId,
        feature.startPosition,
        feature.stopPosition,
        feature.orfId,
        feature.orfType,
        feature.funcClassification,
        feature.rastId,
        feature.strand 
from    feature,strain 
where   feature.id=strain.id and 
        strainName='M18';
