SQL Server 2005 sp_send_dbmail出现Internal error at FormatRowset (Reason: Not enough storage is available to complete this operation)

案例环境:

 

操作系统: Windows 2003 SE 32bit(SP2)

数据库版本:Microsoft SQL Server 2005 - 9.00.5069.00 (Intel X86)

            Aug 22 2012 16:01:52

            Copyright (c) 1988-2005 Microsoft Corporation

            Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 2)

 

案例分析:

如下所示,使用下面SQL语句发送邮件时,遇到一个非常奇怪的错误信息:Not enough storage is available to complete this operation

EXEC msdb.dbo.sp_send_dbmail @recipients = ‘konglb@xxx.com‘,
     @subject = ‘it is only test‘, @body = NULL, @body_format = ‘text‘,
     @query_result_separator = ‘---‘,
     @query = ‘SELECT * FROM  MESDB.dbo.MES_DAILY_CLOSING_LOG‘;

 

Msg 22050, Level 16, State 1, Line 22

Error formatting query, probably invalid parameters

Msg 14661, Level 16, State 1, Procedure sp_send_dbmail, Line 517

Query execution failed: Sqlcmd: Error: Internal error at GetDataRowset (Reason: Not enough storage is available to complete this operation).

Sqlcmd: Error: Internal error at FormatRowset (Reason: Not enough storage is available to complete this operation).

错误虽然提示storage not engough,其实这个错误跟存储没有任何关系,这个表MES_DAILY_CLOSING_LOG里面有三个字段为NVARCHAR(MAX),采取下面两种方式可以临时解决这个问题。

 

1: 如果在@query里面排除这三个NVARCHAR(MAX)字段,那么邮件正常发送,不会出现任何错误。

2: 如果在@query里面将这个字段做一下转换,例如CAST(MAIL_RECEIPS AS NVARCHAR(4000)),那么邮件也能正常发送。

 

在SQL Server 2008、 SQL Server 2012下都不会发生,另外在SQL Server 2005(9.00.5000.00)这个版本下测试,也没有出现这个问题。只有这台服务器会出错,后面在这篇sp_help_jobsteplog fails when run as a @query of sp_send_dbmail章里面反馈,重启数据库服务后,就不会出现这个问题。等了一周等到一个合适的时机重启了服务器,验证发现重启过后,果然这个错误就消失了。网上关于这个错误的资料非常少,严重怀疑是触发了某一个Bug。
