我现在使用SQL-Server 11.0.3128.0已经有一段时间了，通常它只是起作用。
由于某些奇怪的原因，我尝试使用现在几周没有变化的代码从SqlDataReader读取时开始获取SqlExceptions。而且不仅是我，客户也遇到了同样的问题。
我有点不知道怎么调试这个，因为错误信息对我来说没用。发生异常时代码正在从SqlDataReader读取：
using (SqlDataReader rdr = cmd.ExecuteReaderWithEx())
{
while (rdr.Read()) // <-- the SqlException happens here
{
nAllQueryRows = (int)rdr["TotalRowCount"];
rc.Add(new Datenkey(tabelleID, (long)rdr[1]));
}
}
SQL-Command是跨多个数据库和视图的搜索：
WITH NumberedList AS
(
SELECT ROW_NUMBER() OVER (ORDER BY [Artikel_View].[Key]) AS [RowNum]
,[Artikel_View].[Key]
,COUNT(*) OVER () AS [TotalRowCount]
FROM [MyDatabase].dbo.[Artikel_View]
WHERE (([Artikel_View].[GeloeschtAm] IS NULL)
AND (EXISTS (SELECT [Key] FROM [MyDatabase].dbo.[Artikel] WHERE [Artikel_View].[Key] = [Artikel].[Key] AND CONTAINS(*, '"steril"'))
OR EXISTS (SELECT [Key] FROM [MyDatabase].dbo.[ArtikelLieferanten] WHERE [Artikel_View].[Key] = [ArtikelLieferanten].[ArtikelKey] AND CONTAINS(*, '"steril"'))
OR EXISTS (SELECT [Key] FROM [MyDatabase].dbo.[ArtikelLager] WHERE [Artikel_View].[Key] = [ArtikelLager].[ArtikelKey] AND CONTAINS(*, '"steril"'))
OR EXISTS (SELECT [Key] FROM [MyDatabase].dbo.[ArtikelVKPreise] WHERE [Artikel_View].[Key] = [ArtikelVKPreise].[ArtikelKey] AND CONTAINS(*, '"steril"'))
OR EXISTS (SELECT [Key] FROM [MyDatabase].dbo.[KundenReservierteBestaende] WHERE [Artikel_View].[Key] = [KundenReservierteBestaende].[ArtikelKey] AND CONTAINS(*, '"steril"'))))
AND (([Artikel_View].[Nr] LIKE @suchwort1a)
OR ([Artikel_View].[KatalogNr] LIKE @suchwort1a)
OR ([Artikel_View].[PZN] LIKE @suchwort1a)
OR ([Artikel_View].[Hilfsmittelpositionsnummer1] LIKE @suchwort1a)

OR ([Artikel_View].[Suchwort1] LIKE @suchwort1a)
OR ([Artikel_View].[Suchwort2] LIKE @suchwort1a)
OR ([Artikel_View].[Suchwort3] LIKE @suchwort1a)
OR ([Artikel_View].[Suchwort4] LIKE @suchwort1a)
OR ([Artikel_View].[BezeichnungKurz] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.Nr] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.NameVorname] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.KuerzelFuerArtikelNr] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.Suchwort1] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.Suchwort2] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.Suchwort3] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.Suchwort4] LIKE @suchwort1a)
OR ([Artikel_View].[Lieferanten.LieferantKey.UnsereKdNrBeiLieferant] LIKE @suchwort1a)
OR ([Artikel_View].[Lager.StandardLagerplatzKey.Kuerzel] LIKE @suchwort1a))
)
SELECT * FROM NumberedList WHERE RowNum BETWEEN 1 AND 100 ORDER BY [Key]
查询有两个参数（是的，第二个参数从未使用过 - 我会试着去除它）：
@suchwort1a='plast%'
@suchwort1c='%[^A-z^Ä^Ö^Ü^ä^ö^ü^ß]plast%'
它抛出一个SqlException Class 11 Number 0 LineNumber 0 with（german）text“Fürdenaktuellen Befehl ist ein schwerwiegender Fehleraufgetreten.LöschenSieeventuelle Ergebnisse。” （用英语说“当前命令中的严重错误。丢弃结果”）。
错误确实在客户站点发生，但在我的调试系统上只发生了几次。我不知道这个错误试图告诉我什么。对我来说，似乎SQL Server有内部打嗝。如果我重新运行相同的SQL命令它通常会起作用，所以它似乎是服务器的一些短暂的内部条件导致错误。
我该如何解决这个问题？
