Sql 错误：缺少表的From-子句项,sql,postgresql,Sql,Postgresql,在postgresql中我无法理解这一点： SELECT Week1.Material, Week1.VALa, Week1.MVGavgprice, concat(Week1.Material, Week1.VALa) FROM "Week1" 错误：表“week1”的子句条目中缺少第1行：选择Week1.Material、Week1.VALa、Week1.MVGavgprice、concat。。。 ^ SQL状态：42P01 字符：8 去掉周1周围的引号@DanielMarcus可能

在

postgresql

中我无法理解这一点：

SELECT Week1.Material, Week1.VALa, Week1.MVGavgprice, concat(Week1.Material, Week1.VALa)

FROM "Week1"

错误：

表“week1”的子句条目中缺少第1行：选择Week1.Material、Week1.VALa、Week1.MVGavgprice、concat。。。 ^ SQL状态：42P01 字符：8

去掉周1周围的引号@DanielMarcus可能重复如果表格是以指定的敏感度创建的，他将需要在
