超时已过。在操作完成之前超时时间已过或服务器在 VB.Net 中没有响应

Question

我有一个简单的 SQL 查询，在执行查询时在服务器端的 DB 中被触发，有时它会显示错误消息：

超时。在操作完成之前超时时间已过或服务器没有响应。在 System.Data.SqlClient.SqlConnection.OnError(SqlException 异常，Boolean breakConnection) 在 System.Data.SqlClient.SqlInternalConnection.OnError(SqlException 异常，Boolean breakConnection) 在 System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) 在 System System.Data.SqlClient.SqlCommand.RunExecuteNonQueryTds(String methodName, Boolean async) 在 System.Data.SqlClient.SqlCommand 的 .Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)。 System.Data.SqlClient.SqlCommand.ExecuteNonQuery() 处的 InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe)

我的查询是：

If sqlconn.State = ConnectionState.Closed Then sqlconn.Open()
Txn = sqlconn.BeginTransaction

cmd = sqlconn.CreateCommand
cmd.Transaction = Txn
    strSql = "insert into " & tableName _

    addToLogAudit("from savedata_new() for master:" & strSql)

    cmd.CommandText = strSql
    cmd.CommandTimeout = 0 'already included command timeout to 0 still its not working
    res = cmd.ExecuteNonQuery()

我已经包含 Cmd.Commandtimout=0 仍然收到相同的错误消息 感谢您的帮助，提前致谢。

您获得的超时是在连接上，而不是在您的查询上。
