I have used below code to replace a string by another string in `executeUpdate` method.The code is:

```
                  try
                  {
                   Connection cn=null;Statement st=null;
                  Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                  String constring="jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=D:sandeep\\copy of abcdef.mdb;";
                  cn=DriverManager.getConnection(constring, "", ""); 
                  st=cn.createStatement();
                  String sql="UPDATE temp SET mobile = Replace(mobile, '-', '')";
                  st.executeUpdate(sql.toString());
                  }
                 catch(Exception ex){System.out.println(ex);
                  }

```

The exception is:

> 
> java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Undefined function 'Replace' in expression.
>
