When you have a large number of big spreadsheets to insert as a chore, then speed matters. I also prefer to use ODBC and the sequential data reader to read data from Excel, or any other ODBC source, because it is fast and I like to use the bulk copy library to insert ODBC ‘reader’ data into a SQL Server table because it is extremely fast, so we’ll use that. If, for example, you only need the total, count, and variance of a day’s readings, then why on earth would you want to import more than those aggregated figures? Even if you do, these aggregations, performed on the original data, can be used as a ‘reconciliation’ check that you’ve gulped all the data into their final destination without error. This means that you need pull far less data into SQL because you can do a lot of selection and pre-processing before the data gets anywhere near SQL server. There are some features missing, of course, but you can do joins between tables, filter rows to taste, do aggregations and some string manipulations. Worksheets, or areas within worksheets, become tables. If you use the ODBC driver, then your Excel workbook becomes a little SQL-based relational database. It is a Once and Future technology, developed before its time, but now showing its value for processing large volumes of data, despite its quirks, poor documentation and lackluster support. I always feel slightly awkward in talking about ODBC. This article will aim to show how this is done. It is possible to do a lot of filtering and aggregation of data before it ever gets to SQL Server, since you can turn an existing Excel Workbook into a poor-man’s relational database, or even create one. The most important thing, though, is that you can aggregate before you send the data. It is neater than SSIS too, and more versatile. It is quicker than automating Excel and you can do it without requiring a copy of Excel. The most important direction is from Excel to SQL Server, of course. It is reasonably easy to insert data from Excel into SQL Server, or the reverse, from any other ODBC database to any other, using PowerShell. In the long run, i try to make all Modifications as Patches avaiable for official hMailServer, but any new feature by me or other contributers to this Fork will be integrated in the new MSI-Installer first.Getting Data between Excel and SQL Server using ODBC - Simple Talk Skip to content I forked hMailServer and this (and further patches and features) will be part of an alternative, new MSI-Installer which is in development right now.
#Odbc sql server driver shared memory ssl security error install
This fix requires also the presence of MSOLEDB Provider Version 18 to work which needs to be part of the hMailServer Installer or Users need to install it manually first.
#Odbc sql server driver shared memory ssl security error Patch
So he has to review the patch and decide if it should be part of the official version.This is a bit difficult because Martin isnt verry active lately.
#Odbc sql server driver shared memory ssl security error code
To your question: I will isolate the code changes and provide a patch for Martin (which is the only official Developer with Github commit permissions). Will this solution be integrated in the release versions of hMailserver in the future? Ps2: Only SQL-Server 2008 + SP4 installed on top of it and later versions can handle TLS 1.2. Ps: If you connect not via TCP/IP and by Instanceįor example Localhost\SQLEXPRESS you need to switch on Shared Memory Communication in SQL-Server settings.
Testwise switch of Enforce encryption and report bach.

If you switch to "Enforce encryption" any non TLS/SSL Port 1433 (TDS) compliant connection attemp will be refused and you will be informed by Windows Systemlog (Application-Category) about the rejection in full details. Even on SQL-Server 2017 with its latest updates installed, TLS/SSL encryption isnt activated in the SQL-Server TCP settings. To use MS-SQL via TCP/IP v4 or v6 you need to enable its Standard Port 1433 on all IPs or on the specific IP you want MS-SQL-Server to listen.ĭont use Dynamic SQL-Server ports and leave it blank or 0 and use a fixed/static port value 1433 for all IPs because SQL likes to randomly change it otherwise and no Client can connect.Īs you can see in your Loginfo, there is an SQL Hint: MS-SQL-Server is a fork of Sybase SQL-Server because both Companys teamed up arround 1990 and go diffrent ways a few Years later. Make sure Windows Firewall is open,on Port 1433 InBound and also OutBound. DBNETLib is the Sybase/Microsoft TDS (Tabular Data Stream) Protocol listener which basicly listen on Port 1433 (if its a Microsoft SQL-Server Database server) or Port 5000 if its a SAP Sybase ASE-SQL-Database server.
