PRINT @SelectQuery

EXEC sp_executesql @SelectQuery, N'@JobSeekerStatus nvarchar(20)', @JobSeekerStatus

END

大家好，根据您的建议，我从Exec更正为EXEC sp_executesql并将参数作为值传递，Query仍未执行，显示错误消息“Invalid Column'Selected'”（我应该将其作为参数值传递）。无论我传递什么值，它都会显示带有该参数的无效列。

Answer 1

你需要将@JobSeekerStatus包装在3个引号中

更新后使用QUOTENAME（感谢ughai）

E.G

SET @SelectQuery= @SelectQuery + ' WHERE Tbl_JobSeekers.JobSeekerStatus=' + QUOTENAME(@JobSeekerStatus, '''') + ' ORDER BY Tbl_JobSeekers.National_Id DESC'

Answer 2

感谢您的所有建议，工作正常。

我的修改代码：

  SET @SelectQuery= @SelectQuery + ' WHERE Tbl_JobSeekers.JobSeekerStatus='''+ @JobSeekerStatus +''' ORDER BY Tbl_JobSeekers.National_Id DESC'

  EXEC sp_executesql @SelectQuery, N'@JobSeekerStatus nvarchar(20)',@JobSeekerStatus

Answer 3

在SQL Books Online中查看sp_executesql存储过程。

Sql Query Concatenation未执行
