SQLite3 not updating in iOS application - ios

Question

I have a table called Budgets that stores its settings, values, and a purchases nsarray full of the object purchases.
I am not sure what I am doing wrong in my method right here, but it will not update the database on an existing entry. It saves a new budget just fine.
- (BOOL) saveBudget:(Budget *)budget
{
BOOL success = false;
sqlite3_stmt *statement = NULL;
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &database) == SQLITE_OK)
{
if (budget.budgetID > 0) {
NSLog(#"Existing data, Update Please");
NSString *updateSQL = [NSString stringWithFormat:#"UPDATE BUDGETS set name = '%#', budget = '%#', customdate = '%d', customday = '%d', rolloverp = '%d', rollovern = '%d', purchases = ?8 WHERE id = ?", budget.name, budget.budget, budget.customDate, budget.customDay, budget.rolloverP, budget.rolloverN];
const char *update_stmt = [updateSQL UTF8String];
sqlite3_prepare_v2(database, update_stmt, -1, &statement, NULL);
sqlite3_bind_int(statement, 1, budget.budgetID);
sqlite3_bind_blob(statement, 8, [budget.purchases bytes], [budget.purchases length], SQLITE_TRANSIENT);
if (sqlite3_step(statement) == SQLITE_DONE)
{
success = true;
}
}
else
{
NSLog(#"New data, Insert Please");
NSString *insertSQL = [NSString stringWithFormat:#"INSERT INTO BUDGETS (name, budget, customdate, customday, rolloverp, rollovern, purchases) VALUES (\"%#\", \"%#\", \"%d\", \"%d\", \"%d\", \"%d\", ?8)", budget.name, budget.budget, budget.customDate, budget.customDay, budget.rolloverP, budget.rolloverN];
const char *insert_stmt = [insertSQL UTF8String];
sqlite3_prepare_v2(database, insert_stmt, -1, &statement, NULL);
sqlite3_bind_blob(statement, 8, [budget.purchases bytes], [budget.purchases length], SQLITE_TRANSIENT);
if (sqlite3_step(statement) == SQLITE_DONE)
{
success = true;
}
}
sqlite3_finalize(statement);
sqlite3_close(database);
NSLog(#"Save Success");
}
return success;
}
I am assuming that the query is incorrect, but I may be wrong.
EDIT:
Here is how I am adding the database. Again, new entries are added and retrieved from the database just fine. Old entries are retrieved but will not update.
- (void) initDatabase
{
NSString *docsDir;
NSArray *dirPaths;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
databasePath = [[NSString alloc] initWithString:
[docsDir stringByAppendingPathComponent:#"budget.db"]];
NSFileManager *filemgr = [NSFileManager defaultManager];
if([filemgr fileExistsAtPath:databasePath] == NO)
{
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &database) == SQLITE_OK)
{
NSString sql_stmt = #"CREATE TABLE IF NOT EXISTS BUDGETS (";
sql_stmt = [sql_stmt stringByAppendingString:#"id INTEGER PRIMARY KEY AUTOINCREMENT, "];
sql_stmt = [sql_stmt stringByAppendingString:#"name TEXT, "];
sql_stmt = [sql_stmt stringByAppendingString:#"budget DOUBLE, "];
sql_stmt = [sql_stmt stringByAppendingString:#"customdate INTEGER, "];
sql_stmt = [sql_stmt stringByAppendingString:#"customday INTEGER, "];
sql_stmt = [sql_stmt stringByAppendingString:#"rolloverp INTEGER, "];
sql_stmt = [sql_stmt stringByAppendingString:#"rollovern INTEGER, "];
sql_stmt = [sql_stmt stringByAppendingString:#"purchases BLOB)"];
if (sqlite3_exec(database, [sql_stmt UTF8String], NULL, NULL, &errMsg) != SQLITE_OK)
{
NSLog(#"Failed to create table BUDGETS");
}
else
{
NSLog(#"BUDGETS table created successfully");
}
sqlite3_close(database);
}
else
{
NSLog(#"Failed to open/create database");
}
}
}
ANOTHER QUESTION:
I also have a question on whether I am saving the purchases NSArray correctly or not. I assumed that this would work.

Answer 1

Make sure the Location your pointing to the SQlite data base is right.And before executing the query make sure the table is in open state and ready to the operation. Refer this code:
sqlite3_stmt *statement;
sqlite3 *cPDB;
NSString *docsDir;
NSArray *dirPaths;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
// Data base path
databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: #"cPDB.db"]];
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &cPDB) == SQLITE_OK)
{
NSString *querySQL = [NSString stringWithFormat: #"UPDATE USER_SESSION_INFO SET \"%#\" = \"%#\", synState = 'false' WHERE sessionName=\"%#\"",categoryTy,state,sessionName];
const char *query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(cPDB, query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
if((sqlite3_step(statement)) != SQLITE_DONE)
NSLog(#"Not Updated");
else
{
NSLog(#"Succesfully updated row !");
return YES;
}
}
}

Found the problem. There were no single quotes around ?8 in the update statement. Well, its always the small problems. Thanks everyone!
