Unable to send Unicode to SQL Server using pymssql

Question

I\'m having issues sending unicode to SQL Server via pymssql:

In [1]:     import pymssql
            conn = pymssql.connect(host=\'hostname\', user=\'me\', p         


        

Answer 1

The following code samples have been tested and verified to work with both Python 2.7.5 and Python 3.4.3 using pymssql 2.1.1.

For a Python source file saved with UTF-8 encoding:

# -*- coding: utf-8 -*-
import pymssql

cnxn = pymssql.connect(
    server='localhost',
    port='52865',
    user='sa',
    password='whatever',
    database='myDb')
crsr = cnxn.cursor()
crsr.execute("INSERT INTO MyTable (textcol) VALUES (%s)", (u'Monsieur le Curé of the «Notre-Dame-de-Grâce» neighborhood'))
cnxn.commit()
crsr.close()
cnxn.close()

For a Python source file saved with "ANSI" (Windows-1252) encoding:

# -*- coding: windows-1252 -*-
import pymssql

cnxn = pymssql.connect(
    server='localhost',
    port='52865',
    user='sa',
    password='whatever',
    database='myDb')
crsr = cnxn.cursor()
crsr.execute("INSERT INTO MyTable (textcol) VALUES (%s)", (u'Monsieur le Curé of the «Notre-Dame-de-Grâce» neighborhood'))
cnxn.commit()
crsr.close()
cnxn.close()

Note that the only difference between the two samples is the very first line to declare the encoding of the source file.

To be clear, the table receiving the INSERT was:

CREATE TABLE [dbo].[MyTable](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [textcol] [nvarchar](255) NULL,
PRIMARY KEY CLUSTERED 
(
    [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
