Connect MS-Access database from MATLAB

Already I’ve shared the way and source code how to connect MySQL data base from MATLAB. In this post I want to share how to connect to MS-Access. I initially thought of using the MySQL as database but due to some issues of reinstalling the OS and being MySQL not getting installed properly, I went for MS-Access. I hope this post will be very helpful to you if you have come here searching for connecting MS-Access from MATLAB.

function db=insertdb(name, imagePath, ICC)
dbpath = 'C:\Users\MyWindows7\Documents\abc.mdb';
conurl = ['jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)}; DBQ=' dbpath];
con = database('','','','sun.jdbc.odbc.JdbcOdbcDriver', conurl)

%insertQuery=['insert into Image values(' name ',' imagePath ',' ICC ');' ]
%e = exec(con,insertQuery);
colnames={'imgName', 'imagePath', 'iCC'};
values={name, imagePath, ICC};
insert(con, 'Image',colnames, values ) %This statement inserts the values which are contained by values %array variables
%e = fetch(e);
%data = e.Data

In the above program % represents comments you can ignore them if you want. I included them to say that there are several other ways to insert a row into the MS-Access database. In the above code  if you specify the path of database(ie.,        .mdb file) then its enough there is no need for you to specify DSN name and other things. similarly you can also work with other SQL statements. I hope this helps. If you have any more queries or clarifications you can feel free to comment here.

    Hi, i’ve tried to run this (1) in Matlab (R2007b) and it gives me back this (2). It will be much appreciated if you could give me an answer that will solve my problem. Thank you.


    dbpath = ‘C:\Documents and Settings\UnFelDeRoshuAprins\Desktop\aplicatie licenta reloaded\SampleDB.mdb’;
    conurl = [‘jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)}; DBQ=’ dbpath];
    con = database(”,”,”,’sun.jdbc.odbc.JdbcOdbcDriver’, conurl)

    curs=exec(con, ‘select all CNP from Profesori’);

    >> connect

    con =

    Instance: ”
    UserName: ”
    Driver: []
    URL: []
    Constructor: [1×1 com.mathworks.toolbox.database.databaseConnect]
    Message: [1×163 char]
    Handle: 0
    TimeOut: []
    AutoCommit: ‘off’
    Type: ‘Database Object’

    ??? Undefined function or method ‘fetch’ for input arguments of type ‘struct’.

    Error in ==> connect at 9

      Undefined fetch indicates that the data is not in the curs that means the “select” statement has not been executed properly…There could be database connectivity problem or select statement syntax problem in general.. In your case check whether the database exists or not.. or table name correct or not etc., For this database connectivity you can also use the database toolbar in the matlab This is an easy way(GUI based) to check above aspects.. Good luck..
