pymssql: Setting charset option in DB connection causes connection to fail
pymssql execute parameters
adaptive server is unavailable or does not exist pymssql
pymssql.connect windows authentication
I've written a wrapper around
pymssql to connect to the DBs where I work. I've run into unicode decode/encode errors, and I'm trying to stem them at the source.
When I specify
charset='latin1' or'iso-8859-1'`, the Connection fails with the following error:
File "pymssql.pyx", line 549, in pymssql.connect (pymssql.c:7672) raise OperationalError(e) pymssql.OperationalError: (20017, 'DB-Lib error message 20017, severity 9:\nUnexpected EOF from the server\nDB-Lib error message 20002, severity 9:\nAdaptive Server connection failed\n')
The DB encoding looks to be 'latin1':
which, I assume, is the same as Python's
Am I doing this correctly? Did I choose the wrong coded (i.e.,
It appears that it is quite picky about what you enter.
Frequently asked questions, If your script can't connect to a SQL Server instance, try the following: UTF-8" locale charset is "UTF-8" using default charset "UTF-8" Setting tempdb as default Note that I use the -H option rather than the -S option to tsql . These will cause FreeTDS to output a ton of information about what it's doing and you may very 1 pymssql: Setting charset option in DB connection causes connection to fail May 11 '18 1 django countries currency code Dec 28 '14 View all questions and answers →
Use uppercase letters such as "ISO-8859-1" or "LATIN1".
pymssql is using the GNU iconv conventions.
For historical reasons, international text is often encoded using a language or country dependent character encoding. With the advent of the internet and the frequent exchange of text across countries - even the viewing of a web page from a foreign country is a "text exchange" in this context -, conversions between these encodings have become important. They have also become a problem, because many characters which are present in one encoding are absent in many other encodings. To solve this mess, the Unicode encoding has been created. It is a super-encoding of all others and is therefore the default encoding for new text formats like XML.
Still, many computers still operate in locale with a traditional (limited) character encoding. Some programs, like mailers and web browsers, must be able to convert between a given text encoding and the user's encoding. Other programs internally store strings in Unicode, to facilitate internal processing, and need to convert between internal string representation (Unicode) and external string representation (a traditional encoding) when they are doing I/O. GNU libiconv is a conversion library for both kinds of applications.
When pymssql.connect() with charset="cp949" on Windows, crash , 2. try to connect mssql server as below script. import pymssql conn server\nDB-Lib error message 20002, severity 9:\nAdaptive Server connection failed\n') FreeTDS is configured and compiled in below options. And, I find the reason. When error message - Character set conversion is not available Also, pymssql is compiled with '-g' option. Below is captured by DrMingw. python26.exe caused an Access Violation at location 74c9d193 in module msvcrt.dll Reading from location 00000961.
My system uses "SQL_Latin1_General_CP1_CI_AS" collation setting as well, and I found even connecting with "LATIN1", characters in CHAR/VARCHAR columns are still being returned malencoded.
According to Microsoft document on SQL Server Code Page Architecture, the code page to use is Windows-1252.
pymssql.connect gives the correct result for me.

Per your description, the issue is likely from Python application side. Based on this, you may try to add the character "u" at the beginning of the value "test_यूनिकोड_डेटाबेस_123" like this and see if it works.

Configuring Database Character Encoding, Logon,Unknown,Login failed for user 'data_sync_agent'. Reason: Password did not match that for the login provided. Someone can help me with that? self.conn = pymssql.connect(server = host, user = user, password = password, database = database, charset="UTF-8"). Any help will be appreciated. If the pool_name argument is not given, the connect () call automatically generates the name, composed from whichever of the host, port , user, and database connection arguments are given, in that order. If the pool_size argument is not given, the default size is 5 connections.

Setup for SQL Server · Confluence Setup Guide · Troubleshooting failed XML site backups. So if you have SQL Server running on a port other than 1433, you must explicitly specify the port in your call to pymssql.connect. You cannot rely on it to pick up the port in your freetds.conf, even though tsql -S might do this. This is why I recommend using tsql -H instead for diagnosing connection problems.
