Once the blob column retrieves the text_data the driver fails to issue TEXT_PTR only for subsequent column data retrieval. The 5th event above would actually return the entire blob instead of the pointer. To avoid the additional, TDS overhead, place your blob column at the end of ...
假设你使用 sqlncli11 ODBC 驱动程序来访问 Microsoft SQL Server 2012 或应用程序中的 SQL Server 2014。 使用服务器游标和 SQLFetch/ SQLGETDATA 函数访问 SQL server 中的某些二进制大型对象(BLOB)数据时,尤其是对于较大数据类型(如 varbinary (max)或 varchar (max))而言,性能问题会发生。原因...
I have the SQLNCLI11 Driver installed. This is my connection string. Set Con = Server.CreateObject("ADODB.Connection") Con.ConnectionString = "Provider=SQLNCLI11; Trusted_Connection=yes; Database=xxx; Server=xxx All replies (2) Tuesday, June 28, 2016 3:52 PM ✅Answered Hello, Use the ...
First check if the driver is installer and this in the same 32/64 bit architecture as the SQL Server. Open ODBC Admin (odbcad32.exe) and go to tab "Driver"If ODBC driver "SQLNCLI11.DLL" exists, then the OleDB should also work. You can create a "User DSN" to test connection to...
Driver={SQL Server Native Client 11.0};Server=localhost;Database=databank;Uid=myuser;Pwd=mypassword; 尝试了一些方法都没有奏效,甚至将数据更改为12533个字母"A",以确定实际数据是否会造成问题。 之后发现了一件有趣的事情:我先执行了短的SQL查询,然后再执行长的数据字段更新。结果仍然遇到了查询超时异常.....
Fact 1:As per Microsoft’s official documentation,SQL Server Native Client (SQLNCLI) remains deprecatedand you should not use it in new development work. Instead, Microsoft advises that you should use the newMicrosoft OLE DB Driver for SQL Server(MSOLEDBSQL), since it is the driver that ...
The same row data is returned to the client 5 times but the actual blob is only streamed beginning at step #4. *As part of the investigation I found a bug. Once the blob column retrieves the text_data the driver fails to issue TEXT_PTR only for su...
This is a design issue for implementation of the SQLFetch/ SQLGetData function in SQL Server 2012 ODBC driver. When the query uses any server cursors, the ODBC driver invokes sp_cursorfetch during the SQLFetch implementation, and the server sends all the BLOB to the client. Th...
