DBCC CheckDb-vb.net 有什么检测错误的方法吗?

问题描述

我正在使用以下代码检查我的数据库是否有任何问题/需要进行故障排除:

I am using the below code to check if my database has any issues/requires troubleshooting:

Dim cmd As New SqlCommand("DBCC CHECKDB (offpoDb) WITH TABLERESULTS", con)
Dim reader As SqlDataReader = cmd.ExecuteReader
executing.Content = "Checking datatabse for errors"
executing.Margin = New Thickness(243, 111, 0, 0)
While reader.Read
    strBuilder.AppendLine(CStr(reader("MessageText")))
End While
reader.Close()
MessageBox.Show(strBuilder.ToString)

现在，DBCC CHECKDB 命令可能会产生如下结果:

Now, the DBCC CHECKDB command might result in something like this :

CHECKDB 在数据库mydb"中发现 0 个分配错误和 15 个一致性错误

可以修复以下 SQL 查询:

Which can be fixed the following SQL query :

ALTER DATABASE AdventureWorks2008R2 SET SINGLE_USER WITH ROLLBACK 
IMMEDIATE;
BEGIN TRANSACTION;
DBCC CHECKDB ('AdventureWorks2008R2', REPAIR_ALLOW_DATA_LOSS);
ALTER DATABASE AdventureWorks2008R2 SET MULTI_USER;

但是在通过我的应用程序执行以下查询之前，有没有办法知道 DBCC CHECKDB 是否真的返回了任何错误?因为没有任何错误，修复数据库就没用了...

But before executing the following query through my application, is there a way to know if DBCC CHECKDB has really returned any errors at all ? Because without any errors, repairing the database will be useless...

有什么帮助吗?

一个让我心碎的想法

我正在考虑将字符串从 strBuilder 获取到文本框.将检查文本框是否可用以下行 CHECKDB 在数据库中发现 0 个分配错误和 15 个一致性错误...

DBCC CHECKDB (dname) WITH TABLERESULTS, NO_INFOMSGS

SELECT * FROM sys.sysmessages 
WHERE description LIKE '%checkdb%' AND msglangid = 1033 AND severity > 10

For Each c As Char In "CHECKDB found 0 allocation errors and 15 consistency errors"
    If (Char.IsNumber(c)) AndAlso Integer.Parse(c) > 0 Then
        'Errors occured
    End If
Next
