Passing variable in query does not show any result - iphone

Question

I have table in sqlite I want to get data where userNAme and organizatiocode. problem is that it does not show any rows. If I do not pass variable and select all data then it returns rows.
Here is my code
+(void)getInitialData:(NSString *)dbPath {
MultipleDetailViewsWithNavigatorAppDelegate *appDelegate = (MultipleDetailViewsWithNavigatorAppDelegate *)[[UIApplication sharedApplication] delegate];
if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) {
NSLog(#"User NAme is %#",appDelegate.userName);
// const char *sql = "select * from library";
const char *sql = "select * from library where userName=?";
sqlite3_stmt *selectstmt;
if(sqlite3_prepare_v2(database, sql, -1, &selectstmt, NULL) == SQLITE_OK) {
//sqlite3_bind_text(selectStmt, 1, [appDelegate.userName UTF8String], -1, SQLITE_TRANSIENT);
//sqlite3_bind_text(selectStmt, 1, [appDelegate.organizationCode UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(selectStmt , 1, [appDelegate.userName UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(selectStmt , 2, [appDelegate.organizationCode UTF8String], -1, SQLITE_TRANSIENT);
while(sqlite3_step(selectstmt) == SQLITE_ROW) {
NSInteger primaryKey = sqlite3_column_int(selectstmt, 0);
Coffee *coffeeObj = [[Coffee alloc] initWithPrimaryKey:primaryKey];
coffeeObj.userID = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 1)];
coffeeObj.contentAddedDateTime = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,2)];
coffeeObj.contentType = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,3)];
coffeeObj.contentTitle = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,4)];
coffeeObj.contentSource = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,5)];
coffeeObj.contentDescription = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,6)];
coffeeObj.categoryTitle = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,7)];
coffeeObj.subCategoryTitle = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,8)];
coffeeObj.organizationCode = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,9)];
coffeeObj.userName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt,10)];
int count=[appDelegate.libraryArrayLocal count];
NSLog(#"count is beofore getting values %d",count);
[appDelegate.libraryArrayLocal addObject:coffeeObj];
int countone=[appDelegate.libraryArrayLocal count];
NSLog(#"count is after getting values %d",countone);
[coffeeObj release];
}
}
}
else
sqlite3_close(database);
}
}

Try to use:
NSString *query = [NSString stringWithFormat:#"select * from library where userName=%#",appDelegate.userName];
const char *sql = [query UTF8String];
Instead of:
const char *sql = "select * from library where userName=?";
also try without binding,
if(sqlite3_prepare_v2(database, sql, -1, &compiledStatement, NULL) == SQLITE_OK)
{
// Loop through the results and add them to the feeds array
while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
//do your stuff here
}
}
// Release the compiled statement from memory
sqlite3_finalize(compiledStatement);
