sqlite - Java JDBC PreparedStatement Foreign Key Constraint Failed -


i'm designing billing program sqlite , jdbc, , i'm trying use helper method:

public static void preparedinsert(string query, string[] inserters) {     connection c = connect();     try {         preparedstatement statement = c.preparestatement(query);          (int = 0; < inserters.length; i++) {             statement.setobject(i + 1, "\'" + inserters[i] + "\'");         }         statement.executeupdate();         c.commit();         joptionpane.showmessagedialog(null, "database updated!");      } catch (sqlexception e) {         joptionpane.showmessagedialog(null, "error updating database: " + e.getmessage());     }     disconnect(c); }  public static connection connect() {     connection c = null;     try {         class.forname("org.sqlite.jdbc");         sqliteconfig config = new sqliteconfig();           config.enforceforeignkeys(true);           c = drivermanager.getconnection("jdbc:sqlite:mrwbilling.db", config.toproperties());         c.setautocommit(false);     } catch ( exception e ) {         joptionpane.showmessagedialog(null, "error connecting database: " + e.getmessage());     }     return c; }  public static void disconnect(connection c) {     try {         c.close();     } catch (sqlexception e) {         joptionpane.showmessagedialog(null, "error disconnecting database: " + e.getmessage());     } }

the parameter i'm trying pass in this:

sqlitejdbc.preparedinsert("insert timesheets(date, attorney, notes) values(?, ?, ?);",              new string[]{date, attorneyname, notes});

timesheets has 4 rows: id, date, attorney , notes id set autoincrement , attorney foreign key attorney table. attorneyname i'm passing in exists in attorney's table.

this working fine during prior build when using regular statements, i've swapped prepared statements, i'm getting this:

error updating database: [sqlite_constraint] abort due constraint violation (foreign key constraint failed)

i'm @ loss i'm doing wrong. suggestions?

the additional single quotes wrapping parameters causing fk violation. use instead in loop:

statement.setstring(i+1, inserters[i]);

you may need remove semicolon insert statement.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
