Question

真的需要你帮忙解决这个问题...我试图为建筑公司的工作描述生成报告。但是，为了生成报告，我遇到了跳过空列的问题。在对谷歌进行研究后，我发布了别名，但我仍然无法跳过空列

存储在数据库中：

CompNo|CodeA|CodeB|CodeC|CodeD|CodeE|CodeF|CodeG|CodeH|CodeI|CodeJ|CodeK|
A10001|     |     |     |     |     |     |     |     |     | W09 |     |
A10003| W01 | W02 |     | W04 |     |     |     | W07 | W08 |     | W10 |
A10002| W01 | W02 | W03 | W04 |     |     |     | W07 | W08 | W09 | W10 |

报告中的预期输出：

A10001  W09                                                                   
A10003  W01 W02 W04 W07 W08 W10               
A10002  W01 W02 W03 W04 W07 W08 W09 W10

目前生成的报告：

A10001                                            W09                                                                    
A10003  W01 W02     W04                   W07 W08               W10                                                                            
A10002  W01 W02 W03 W04                   W07 W08 W09           W10

下面是我已经使用的代码......它看起来很好......但我需要消除 tblCompanyWrkDesc （表名）中的空列，如果数据不可用。

select tblCompany.compno, tblCompany.CompName, tblcompany.CompAdd, tblCompany.CompTel, tblCompany.CompFax, tblCompany.CompEmail, 
tblCompany.CntcPerName, tblCompany.CntcPerTel, tblCompany.RegNo, 
tblCompany.RocRob, tblCompany.Cidb, tblCompany.Spkk, tblCompany.Ppk, tblCompany.Status, tblCompany.Others,



Substring(tblCompany.RegDate,7,2) + '/' + Substring(tblCompany.RegDate,5,2) + '/' + Substring(tblCompany.RegDate,1,4) as Rd, 
Substring(tblCompany.VldtStart,7,2) + '/' + Substring(tblCompany.VldtStart,5,2) + '/' + Substring(tblCompany.VldtStart,1,4) as Fd, 
Substring(tblCompany.VldtEnd,7,2) + '/' + Substring(tblCompany.VldtEnd,5,2) + '/' + Substring(tblCompany.VldtEnd,1,4) as Ld, 

tblCompanyWrkDesc.Compno, tblCompanyWrkDesc.CodeA+' '+tblCompanyWrkDesc.CodeB+' '+tblCompanyWrkDesc.CodeC+' '+tblCompanyWrkDesc.CodeD+' '+tblCompanyWrkDesc.CodeE+' '+tblCompanyWrkDesc.CodeF+' '+tblCompanyWrkDesc.CodeG+' '+tblCompanyWrkDesc.CodeH+' '+tblCompanyWrkDesc.CodeI+' 
'+tblCompanyWrkDesc.CodeJ+' '+tblCompanyWrkDesc.CodeK+' '+tblCompanyWrkDesc.CodeL+' '+tblCompanyWrkDesc.CodeM+' '+tblCompanyWrkDesc.CodeN+' 
'+tblCompanyWrkDesc.CodeO+' '+tblCompanyWrkDesc.CodeP+' '+tblCompanyWrkDesc.CodeQ+' '+tblCompanyWrkDesc.CodeR+' '+tblCompanyWrkDesc.CodeS+' 
'+tblCompanyWrkDesc.CodeT+' '+tblCompanyWrkDesc.CodeU+' '+tblCompanyWrkDesc.CodeV+' '+tblCompanyWrkDesc.CodeW+' '+tblCompanyWrkDesc.CodeX as WorkDesc, 
tblCompanyWrkDesc.CodeOthers, tblCompanyWrkDesc.Other

from tblCompany, tblCompanyWrkDesc

WHERE tblCompanyWrkDesc.Compno = tblCompany.compno
ORDER BY tblCompany.RefNo

是否可以跳过别名语句的空列
