java - MsAccess SQL Exception Too few parameters -

-

currently making java program grabs data off of msaccess database , of these errors extremely frustrating. keep getting sql.exception : few parameters. expected 1 error on last remaining bugs in program.

little background on db: has 3 tables (a player table (11 columns), team table (3 columns), , opponent table (6 columns).

these both of functions , problem lies in here somewhere

conn = connect.connectdb();     string sql = "insert player ("+"playerlastname,"+"playerfirstname,"+"position)"+ "values("+txtid.gettext()+ ",'"+txtname.gettext()+"','"+txtaddress.gettext()+"')" ;     try{         pst = conn.preparestatement(sql);         pst.executequery();         pst.setstring(1, txtid.gettext());         pst.setstring(2, txtname.gettext());         pst.setstring(3, txtaddress.gettext());         joptionpane.showmessagedialog(null, txtid.gettext() + " saved");         updatejtable();         //conn.close();     }     catch(exception e){         joptionpane.showmessagedialog(null, e);     }

or function

        string sql = "select * player playerlastname = " +txtid.gettext()+ "";     string pine = null;     try{         pst = conn.preparestatement(sql);          resultset res;         res = pst.executequery();          pine.equalsignorecase(jtable1.getmodel().getvalueat(rowsu, 10).tostring());          while(res.next()){             joptionpane.showmessagedialog(null, txtname + " " + txtid.gettext() + " has total of " +"4");//+ pine);//res.getint("penalties") );          }         updatejtable();      }     catch(exception e){         joptionpane.showmessagedialog(null, e);     }

for 1 thing, looks you're missing single quotes around last name in insert statement.

there may other errors well, that's first thing noticed.

this should pretty easy debug if log sql string before executing it.

edit

i think calls setstring() problem. here how should this:

conn = connect.connectdb();     string sql = "insert player (playerlastname, playerfirstname, position) values(?, ?, ?)";     try{         pst = conn.preparestatement(sql);         pst.setstring(1, txtid.gettext());         pst.setstring(2, txtname.gettext());         pst.setstring(3, txtaddress.gettext());         pst.execute();         joptionpane.showmessagedialog(null, txtid.gettext() + " saved");         updatejtable();         //conn.close();     }     catch(exception e){         joptionpane.showmessagedialog(null, e);     }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
