Update Data Into SQLite Database - ios

Question

I want to update the data into sqlite db.I tried and followed lot of links and methods for update data.But all these do not work out for me.
when i insert my data, following data inserted in db with no problem.
NSString *insertSQL = [NSString stringWithFormat:#"INSERT INTO BusinessCardAppOneTable (NamorTitofImginTxtFld ,TxtofTxtView ,ImaGe,Location,Date,Time)VALUES(?,?,?,?,?,?);"];
NOTE:For image i created the image folder(path) in DB.
Then i fetched and i displayed these data from DB to tableview.
Then i edited NamorTitofImginTxtFld,TxtofTxtView,Date,Time (These are in edit view controller-where i get the image,location,date,time,NamorTitofImginTxtFld,TxtofTxtView from tableview(fetch data))
After that i edited NamorTitofImginTxtFld,TxtofTxtView,date and time.Also if i want to set the date and time i should go to REMAINDER VIEW CONTROLLER(from remainder button of edit view controller to remainder view controller).Where i set the date and time picker.Once i set that and back to edit view controller i can see the edited part.
So my update query is
NSString *updateSQL = [NSString stringWithFormat:#"UPDATE BusinessCardAppOneTable SET NamorTitofImginTxtFld = ?, TxtofTxtView = ?,Date = ? WHERE Time =? "];
If i only edited NamorTitofImginTxtFld and TxtofTxtView,these only updated in db.But if i edited all NamorTitofImginTxtFld , TxtofTxtView with date and time all these do not update.
Anyone can explain about the database update and how to update these 4 columns in db successfully?

Answer 1

I submitted the 3 various options
first //it match up ur answer
update BusinessCardAppOneTable set NamorTitofImginTxtFld = ?, TxtofTxtView = ?, Date = ?, Time =? where id = 5 // here u need to identify your id, if it is correct it surely update
second //it is related to your answer
Yes You can use Parametrized Query as Below :-
NSString *sqlString = #"update BusinessCardAppOneTable set NamorTitofImginTxtFld = ?, TxtofTxtView = ?, Date = ?, Time =? where id = ?";
sqlite3_stmt *stmt;
if(sqlite3_prepare(database, [sqlString UTF8String], -1, &stmt, NULL) != SQLITE_OK)
{
//Handle Error
}
if(sqlite3_bind_text(stmt, 1, [record.name UTF8String],[record.type UTF8String],[record.state UTF8String], -1, SQLITE_TRANSIENT) != SQLITE_OK)
{
// Handle Error
}
if(sqlite3_bind_int(stmt, 2, record.key) != SQLITE_OK)
{
// Handle Error
}
if (sqlite3_step(statement) != SQLITE_DONE)
{
// Handle Error
}
And your Parametrized Code is ready.
