errors trying to read Access Database Tables into Pandas with PYODBC -


i performing simple task of bringing table data ms access database pandas in form of dataframe. had working great , can not figure out why no longer working. remember when troubleshooting connection there work needed around installing new microsoft database driver correct bitness have revisited , gone through reinstallation of driver. below using setup.

record of install on laptop:

  • os: windows 7 professional 64-bit (verified 9/6/2017)
  • access version: access 2016 32bit (verified 9/6/2017)
  • python version: python 3.6.1 (64-bit) found using >python -v (verified 9/11/2017)
  • the accessdatabaseengine needed based on python bitness above
  • windows database engine driver installed accessdatabaseengine_x64.exe 2010 release using >accessdatabaseengine_x64.exe /passive (verified 9/11/2017)

i running following simple test code try out connection test database.

import pyodbc import pandas pd  [x x in pyodbc.drivers() if x.startswith('microsoft access driver')]

returns:

['microsoft access driver (*.mdb, *.accdb)']

setting connection string.

dbpath = r'z:\1users\myfiles\software\jupyternotebookfiles\testdb.accdb' conn_str = (r'driver={microsoft access driver (*.mdb, *.accdb)};''dbq=%s;' %(dbpath)) cnxn = pyodbc.connect(conn_str) crsr = cnxn.cursor()

verifying connected db...

for table_info in crsr.tables(tabletype='table'):     print(table_info.table_name)

returns:

testtable1

trying connect testtable1 gives error below.

dftable = pd.read_sql_table(testtable1, cnxn)  --------------------------------------------------------------------------- nameerror                                 traceback (most recent call last) <ipython-input-14-a24de1550834> in <module>() ----> 1 dftable = pd.read_sql_table(testtable1, cnxn)       2 #dfquery = pd.read_sql_query("select [testquery1]", cnxn)  nameerror: name 'testtable1' not defined

trying again single quotes gives error below.

dftable = pd.read_sql_table('testtable1', cnxn)  --------------------------------------------------------------------------- notimplementederror                       traceback (most recent call last) <ipython-input-15-1f89f9725f0a> in <module>() ----> 1 dftable = pd.read_sql_table('testtable1', cnxn)       2 #dfquery = pd.read_sql_query("select [testquery1]", cnxn)  c:\users\myfiles\anaconda3\lib\site-packages\pandas\io\sql.py in read_sql_table(table_name, con, schema, index_col, coerce_float, parse_dates, columns, chunksize)     250     con = _engine_builder(con)     251     if not _is_sqlalchemy_connectable(con): --> 252         raise notimplementederror("read_sql_table supported "     253                                   "sqlalchemy connectable.")     254     import sqlalchemy  notimplementederror: read_sql_table supported sqlalchemy connectable.

i have tried going driver issue , reinstalling 32bit version without luck.

anybody have ideas?

per docs of pandas.read_sql_table:

given table name , sqlalchemy connectable, returns dataframe. function not support dbapi connections.

since pyodbc dbapi, use query method, pandas.read_sql con argument support dbapi:

dftable = pd.read_sql("select * testtable1", cnxn)
