File attachment or query results size exceeds allowable value of 1000000 bytes

DECLARE
    @tab char(1) = CHAR(9)
EXEC msdb.dbo.sp_send_dbmail
    @profile_name = ‘backupNotify‘,
    @recipients = ‘[email protected]‘,
    @query = ‘select cardno,badge,empname,empdep,swptime,macip from  CanteenProject.dbo.ADSSwipData where badge like ‘‘T%‘‘ and (swptime>CONVERT(varchar(7),DATEADD(mm,-1,GETDATE()),23)+‘‘-21‘‘ and swptime<CONVERT(varchar(7),GETDATE(),23)+‘‘-21‘‘)‘,
    @subject = ‘Monthly Trainees Checkin Log‘,
    @attach_query_result_as_file = 1,
    @query_attachment_filename=‘TraineesCheckin-ConfidentialData.csv‘,
    @query_result_separator=@tab,
    @query_result_no_padding=1

单独执行上面的语句，报错：

File attachment or query results size exceeds allowable value of 1000000 bytes.

解决办法：

配置‘数据库邮件’，将‘最大文件大小（字节）’设置得大些。
