I get the following error when I try to connect to SQL Server directly with a C++Builder 10.2 Tokyo application. I couldn't locate the library requested despite all my searching.
Can anyone help? I'm at a crossroad to decide to continue with C++Builder or Xamarin.
Do you have C++ Builder Enterprise or Architect edition? You need this to connect to SQL Server using FireDAC. C++ Builder Professional edition can only connect to local databases.
Looking at this page:
Embarcadero Microsoft SQL interface
suggests to me that Microsoft SQL with Android client is not supported.
FDConnection is FMX compatible, but the drivers for various OSes are not.
There's a company called Devart that develops direct access connectivity for RAD studio mobile devices; Not sure if this will work if you only have C++ builder; but worth a try;
I'm currently in the same pickle and I'm busy writing a tcpclient/server proxy fmx app that will run on a windows server[where the mssql driver will work]
The idea is to connect from mobile device with tcp client to tcp server component running on windows and have that app grab the info i need for mobile app. Not the fastest solution in long run as you have to do all your authentication and encryption yourself and not the cheapest either as it requires an online windows server or pc... but if you already have it, you might as well use it.
Will update if it succeeds or fails
I am trying to write a script to connect to all version's of oracle database starting from the latest to the oldest version of database.
I tried myself with cx_oracle library found like it needs a client library in the local to connect to remote database like if I download the latest version then it will work up to latest few versions not all.
Also tried with Sqlalchemy connection which is also using cx_oracle libraries.
Please do guide me if am doing anything wrong? I would also like to hear if there are any other ways to connect to the database using PYTHON
cx_Oracle 6 and higher already support connecting to any Oracle database from 9i all the way up to 18c depending on the client that you are using. cx_Oracle requires Oracle Client libraries at least at 11.2. You can see the interoperability notes here. Since anything earlier than 11.2 is no longer supported anyway, that should be adequate in almost all circumstances.
You can also use ODBC to connect to the database but that won't perform as well as cx_Oracle does.
I have an 11.2 Oracle database client on my corporate Windows 7 laptop and use cx_Oracle to connect to databases from version 9.2 to 12.2 without any difficulty.
The other way I connect to databases of all versions is to wrap Python around the Linux version of Oracle's sqlplus utility. This way I do not need to install cx_Oracle and can run with an older Oracle client and the version of Python that comes with the Linux distribution. In my case I am running on Redhat 6 which comes with Python 2.6. I connect to databases from version 8.1 to 12.2 in this way.
I have a blog post about how I run sqlplus from Python on Linux: https://www.bobbydurrettdba.com/2016/11/04/running-sqlplus-from-a-python-script/

I'm using https://www.npmjs.org/package/odbc in an application targeting Windows.
Therefore it requires users to install Microsoft ODBC driver for SQL Server located here, which is a problem if the user doesn't have admin rights.
Any workaround?
You can use another system for databases, mongoDB, sqlite, etc. if your application is simply, i recommend sqlite
Can you use DreamFactory with MS SQL Server (non-azure) install on my local server? I am trying to find rest service that will work with my AngularJS app.
Yes, DreamFactory DSP supports MS SQL Server (azure or local install). DSP installs are not currently supported on Windows OS, but you can connect to your local install of your database as a remote SQL DB service from any DSP using the same setup as noted here. DSPs come with several sample apps, one of which is AngularJS based. If you have more questions about db connections or using Angular, please see http://dreamfactory.com/developers/support.
We have a Windows machine running SQL Server 2005, and we need to be able to run some database queries on it from a Linux box. What are some of the recommended ways of doing this? Ideally, we would want a command-line utility similar to sqlcmd on Windows.
FreeTDS + unixODBC or iODBC
Install first FreeTDS, then configure one of the two ODBC engines to use FreeTDS as its ODBC driver. Then use the commandline interface of the ODBC engine.
unixODBC has isql, iODBC has iodbctest
You can also use your favorite programming language (I've successfully used Perl, C, Python and Ruby to connect to MSSQL)
I'm personally using FreeTDS + iODBC:
$more /etc/freetds/freetds.conf
[10.0.1.251]
host = 10.0.1.251
port = 1433
tds version = 8.0
$ more /etc/odbc.ini
[ACCT]
Driver = /usr/local/freetds/lib/libtdsodbc.so
Description = ODBC to SQLServer via FreeTDS
Trace = No
Servername = 10.0.1.251
Database = accounts_ver8
sql-cli is a nodejs based cross platform command line interface for sql server. You can install it via npm https://www.npmjs.org/package/sql-cli
It can connect to both on-premise and sql azure instance.
sqsh + freetds.
sqsh was primarily an isql replacement for Sybase SQL Server (now ASE) but it works just fine for connecting to SQL Server (provided you use freetds).
To compile, simply point $SYBASE to freetds install and it should work from there. I use it on my Mac all day.
The best part of sqsh are the advanced features, such as dead simple server linking (no need to set up linked servers in SQL Server), flow control and looping (no more concatenating strings and executing dynamic SQL), and invisible bulk copy/load.
Anyone who uses any other command line tool is simply crazy! :)
pymssql is a DB-API Python module, based on FreeTDS. It worked for me. Create some helper functions, if you need, and use it from Python shell.
Mono contains an ADO.NET provider that should do this for you. I don't know if there is a command line utility for it, but you could definitely wrap up some C# to do the queries if there isn't.
Have a look at http://www.mono-project.com/TDS_Providers and http://www.mono-project.com/SQLClient
Since November 2011 Microsoft provides their own SQL Server ODBC Driver for Linux for Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES).
Download Microsoft ODBC Driver 11 for SQL Server on Red Hat Linux
Download Microsoft ODBC Driver 11 for SQL Server on SUSE - CTP
ODBC Driver on Linux Documentation
It also includes sqlcmd for Linux.
If you are using Java, have a look at JDBC.

You don't say what you want to do with the resulting data, but if it's general queries for development/maintenance then I'd have thought Remote Desktop to the windows server and then using the actual SQL Server tools on their would always have been a more productive option over any hacked together solution on Linux itself.
There is an abstraction lib available for PHP. Not sure what your client's box will support but if its Linux then certainly should support building a PHP query interface with this:
http://adodb.sourceforge.net/ Hope that helps you.
I'd like to recommend Sqlectron. Besides being open source under MIT license it's multiplatform boosted by Electron. Its own definition is:
A simple and lightweight SQL client desktop with cross database and platform support
It currently supports PostgreSQL, MySQL, MS SQL Server, Cassandra and SQLite.
Surprised no one has mentioned that, contrary to what other answers seem to suggest, FreeTDS is all you need. No need for unixODBC, iODBC or anything else on top of it.
run some database queries [...] command-line utility similar to sqlcmd on Windows
tsql does this and is part of the FreeTDS package (as are freebcp and other utilities). tsql does not have fancy UI, but if you want a command-line utility that is light, functional and performant, it'll do just fine.
See e.g. How to run a SQL script in tsql
And by light, I mean under 500kb in size (maybe under 60k depending on how it's compiled) and, as far as I have seen, extremely efficient with memory and CPU.
I was not confortable with the freetds solution,
it's why i coded a class (command history, autocompletion on tables and fields, etc.)

If you use eclipse you can install Data Tools Platform plugin on it and use it for every DB engines including MS SQLServer. It just needs to get JDBC driver for that DB engine.
There is a nice CLI based tool for accessing MSSQL databases now.
It's called mssql-cli and it's a bit similar to postgres' psql.
Gihub repository page
Install for example via pip (global installation, for a local one omit the sudo part):
sudo pip install mssql-cli
