android - creating a foreign key in sqlite database -

-

i need create foreign key map tables. foreign primary key of table. insert statement creting issue. sqlite database. table primary key is

db.execsql("create table if not exists "             + main             + "(rowid integer primary key autoincrement not null,appln_date varchar,appln_no varchar,rupees varchar,tenure varchar,asset varchar);");

the table foreign key 

db.execsql("create table if not exists "             + applicant             + "(appid integer primary key autoincrement, " +                     "app_salutation varchar,app_fname varchar,app_mname varchar,app_lname varchar,app_door varchar,app_street varchar,app_building varchar,app_area varchar,app_post varchar,app_tehsil varchar,app_state varchar,app_landmark varchar,rowid integer references "+main+"(rowid));");

the insert statement 

openorcreatedatabase();     createappinfo();     string insertstring = "insert " + applicant             + " values(";      string instring = "";     (int =0; < data.size(); i++) {          instring = instring + "\"" + data.get(i) + "\",";      }      instring = instring.substring(0, instring.length() - 1);     int row=db.rawquery("select * "+main+";" ,null).getcount()+1;     insertstring = insertstring + row+"," +instring + ");";     system.out.println("** insert value ** " + insertstring);     db.execsql(insertstring);      closedatabase();

but code generating error..

04-25 11:43:57.422: e/sqlitelog(17825): (1) table applicanttable has 14 columns 13 values supplied

you should make on database statements this:

create table if not exists "main" (rowid integer primary key autoincrement not null,appln_date varchar,appln_no varchar,rupees varchar,tenure varchar,asset varchar); create table if not exists "applicant" (appid integer primary key autoincrement, app_salutation varchar,app_fname varchar,app_mname varchar,app_lname varchar,app_door varchar,app_street varchar,app_building varchar,app_area varchar,app_post varchar,app_tehsil varchar,app_state varchar,app_landmark varchar,rowid integer references "main"(rowid)); insert "applicant" values("11","a","b","c","d","e","f","g","h","i","j","k","l", (select count(*) +1 main));

the values in example random.

so if 100% sure statement return values except last one. last argument should this: 

insertstring = "rowid integer references "main"(rowid);";

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
