创建存储过程并将日期手动添加到文件名

Question

我是 SQL 管理的新手，负责创建一些夜间作业，这些作业发送一封电子邮件，其中包含电子表格中包含的某些详细信息，到目前为止，我有以下内容：

EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'support',
@recipients = 'test@mail.co.uk',
@subject = 'Post Code Analysis',
@query = N'SET ANSI_WARNINGS OFF;SET NO COUNT ON;select substring(PostOfficeBox,1,4) as ''Postcode''
, COUNT(CASE WHEN New_accounttype = 1 THEN New_AccountType ELSE NULL END) as ''New Connections''
, COUNT(CASE WHEN New_accounttype = 2 THEN New_AccountType ELSE NULL END) as ''Domestic Metered''
, COUNT(CASE WHEN New_accounttype = 3 THEN New_AccountType ELSE NULL END) as ''Commercial Metered Low''
, COUNT(CASE WHEN New_accounttype = 4 THEN New_AccountType ELSE NULL END) as ''Commerical Metered High''
, COUNT(CASE WHEN New_accounttype = 5 THEN New_AccountType ELSE NULL END) as ''Domestic Keypad''
, COUNT(CASE WHEN New_accounttype = 6 THEN New_AccountType ELSE NULL END) as ''Generator''
, COUNT(CASE WHEN New_accounttype = 7 THEN New_AccountType ELSE NULL END) as ''Commercial Keypad''
from be_crm4_MSCRM.dbo.AccountExtensionBase as a
INNER JOIN be_crm4_MSCRM.dbo.CustomerAddressBase as b ON a.AccountId =     b.ParentId
where New_AccountStage = 7
and AddressTypeCode = 1
and substring(PostOfficeBox,1,2) = ''BT''
group by substring(PostOfficeBox,1,2),substring(PostOfficeBox,1,4)
order by substring(PostOfficeBox,1,2),substring(PostOfficeBox,1,4);',
@attach_query_result_as_file = 1,
@query_attachment_filename = 'pca-test.csv',
@query_result_header =0,
@query_result_separator = ' '

在@query_attachment_filename 中，我想附加日期并尝试使用 SELECT CONVERT(VARCHAR(10), GETDATE(), 103) AS [DD/MM/YYYY] 并将其附加到文件名中，如下所示：

@query_attachment_filename = 'pca-test-' + SELECT CONVERT(VARCHAR(10), GETDATE(), 103) AS [DD/MM/YYYY] + '.csv'

任何建议将不胜感激

首先声明一个变量 - 但为此使用格式 112。像这样：

DECLARE @query_attachment_filename NVARCHAR(255) = 
    N'pca-test-' + 
    CONVERT(NCHAR(8), GETDATE(), 112) + 
    N'.csv';

EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'support',
...
@attach_query_result_as_file = 1,
@query_attachment_filename = @query_attachment_filename,
@query_result_header =0,
@query_result_separator = ' '
