I'm trying to open a mdf sql database file that I have saved to my desktop. How do you open it as a pandas dataframe? so far all I have is the following: conn=pyodbc.connect(driver='{SQL Server}', dsn=filepath) Its giving me the error message OperationalError: ('08001', '[08001] [Microsoft][ODBC SQL Server Driver]Neither DSN nor SERVER keyword supplied (0) (SQLDriverConnect)') I found another question that was similar but it was also unanswered. I have also been unable to find a good tutorial to start using sql databases with python I'm very new to the topic. Let me know if there is any extra

I tried a lot of examples from internet to include a MS Access connection to my python project without sucess I have my python project in Eclipse with Anaconda, and my code is: import win32com.client import pyodbc def ado(): ''' connect with com dispatch objs ''' conn = win32com.client.Dispatch(r'ADODB.Connection') DSN = ('PROVIDER = Microsoft.Jet.OLEDB.4.0;DATA SOURCE = ' + db + ';') conn.Open(DSN) rs = win32com.client.Dispatch(r'ADODB.Recordset') strsql = "select * from Empresas" rs.Open(strsql, conn, 1, 3) t = rs.GetRows() conn.Close() return t def odbc(): ''' connects with odbc ''' constr

I'm trying to add a column to an MS Access database table using pyodbc and Python 3.5. Using the expression self.cursor.execute("ALTER TABLE data ADD COLUMN testColumn TEXT(10)") works fine, but when I try to add a default value (DEFAULT "no"), it throws a Syntax error. I've tried multiple combinations, but no luck. Any help is much appreciated! Cheers Sadly, the Access ODBC driver simply does not support the DEFAULT clause for a column in CREATE/ALTER TABLE statements. The ODBC driver and OLEDB provider for Access have diverged somewhat in their DDL support, so unfortunately we can get

I am trying to connect Python to MS Access Database using pyodbc but every time I get the following error: pyodbc.InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)') And this what I have written to connect python to MS Access: import pyodbc conn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=D:\PILOT_DATA.accdb;') cursor = conn.cursor() cursor.execute('select * from p_inventor') for row in cursor.fetchall(): print (row) According to the error, it doesn't find the Data

I try to JOIN two MS access tables this way in python (pyodbc): query = "SELECT Karta.id FROM Karta JOIN zaznam ON (Karta.id=zaznam.karta)" cursor.execute(query) But I am getting an error: pyodbc.ProgrammingError 42000 microsoft access driver syntax error in form clause -3506 SqlExecDirectW What am I doing wrong? You need to specify the type of join ( INNER , LEFT OUTER , RIGHT OUTER ) in the FROM clause. The type of join used depends on what you want the results to contain, I'm guessing you want an INNER JOIN . A reference for the join types available in Access can be found here . Sample code

Basically I'm trying to update Column1_mbgl field data in Table1, all based in MS Access database. The script gets executed without any errors, but when the table is checked no update occurred. I have tried two options as shown in the code without any success. The second option is the SQL code generated directly from MS Access query. Can anybody suggest what I'm missing in the code? #import pypyodbc import pyodbc # MS ACCESS DB CONNECTION pyodbc.lowercase = False conn = pyodbc.connect( r"Driver={Microsoft Access Driver (*.mdb, *.accdb)};" + r"Dbq=C:\temp\DB_access.accdb;") # OPEN CURSOR AND
