SQL查詢定義列別名的錯誤

Question

我的下列sql查詢給了我下面的錯誤，這是什麼意思。我是否正在用扭曲的方式定義別名fir列。這個你能幫我嗎。 我的錯誤是這個，我正在查詢下面的錯誤。

Error in SELECT clause: expression near 'Year'. 
Missing FROM clause. 
Unable to parse query text. 



SELECT [tbl_students].passing_year as Passing Year,[tbl_branch].branch_name as Branch_Name FROM [tbl_students], [tbl_course], [tbl_branch] WHERE [tbl_students].course_id=@courseId 
         AND [tbl_students].branch_id IN(64) 
         AND [tbl_students].course_id=[tbl_course].course_id AND [tbl_students].branch_id=[tbl_branch].branch_id       
         AND (@firstYrPercent is null OR [tbl_students].first_year_percent>=@firstYrPercent) 
         AND (@secondYrpercent is null OR [tbl_students].second_year_percent>=@secondYrPercent) 
         AND (@thirdYrPercent is null OR[tbl_students].third_year_percent>=@thirdYrPercent) 
         AND (@finalYearpercent is null OR [tbl_students].final_year_percent>=@finalYearpercent)

你需要逃避你傳遞新年用方括號列（見第一行）：

SELECT [tbl_students].passing_year as [Passing Year], 
     [tbl_branch].branch_name as Branch_Name 
FROM [tbl_students], [tbl_course], [tbl_branch] 
WHERE [tbl_students].course_id=@courseId 
AND [tbl_students].branch_id IN(64) 
AND [tbl_students].course_id=[tbl_course].course_id AND [tbl_students].branch_id=[tbl_branch].branch_id       
AND (@firstYrPercent is null OR [tbl_students].first_year_percent>=@firstYrPercent) 
AND (@secondYrpercent is null OR [tbl_students].second_year_percent>=@secondYrPercent) 
AND (@thirdYrPercent is null OR[tbl_students].third_year_percent>=@thirdYrPercent) 
AND (@finalYearpercent is null OR [tbl_students].final_year_percent>=@finalYearpercent) 
AND (@currentDegeePercentage is null OR [tbl_students].current_degree_percent>=@currentDegeePercentage) 
AND (@passoutYear is null OR [tbl_students].passing_year>=@passoutYear) 
AND (@currentBacklog is null OR [tbl_students].current_backlog=@currentBacklog) 
AND (@sex is null OR [tbl_students].gender=@sex) 
AND (@eGap is null OR [tbl_students].gapin_education<=@eGap) 
AND (@highSchoolPercentge is null OR [tbl_students].highschool_percentage>=@highSchoolPercentge) 
AND (@higherSchoolPercentage is null OR [tbl_students].ssc_percentage>=@higherSchoolPercentage) 
AND (@grauationPercentage is null OR [tbl_students].graduation_percentage>=@grauationPercentage) 
AND (@diplomaPercentage is null OR [tbl_students].diploma_percentage>=@diplomaPercentage) 
AND (@noOfAtkt is null OR [tbl_students].number_of_ATKT<=@noOfAtkt) 
AND (@validDate is null OR [tbl_students].DOB>=@validDate)
