Getting error in Sqlite ios Failed to open db connection? - ios

Question

I'm building an iOS app using storyboards.I have integrated sqlite database in my app.
I'm unable to insert data into the table,i'm getting this error:
Failed to open db connection
I have created twoo more table with the same code that is working fine but this sports is my third table in which i'm getting this error.
here is my code
//SQLlite database code used to get file path
-(NSString *) getSportsFilePath {
NSString * docsPath= NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES)[0];
return [docsPath stringByAppendingPathComponent:#"sportsdb.db"];
}
-(int) createTable:(NSString*) filePath {
sqlite3* db = NULL;
int rc=0;
rc = sqlite3_open_v2([filePath cStringUsingEncoding:NSUTF8StringEncoding], &db, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL);
if (SQLITE_OK != rc) {
sqlite3_close(db);
}
else {
char * query ="CREATE TABLE IF NOT EXISTS sportsselection (id INTEGER PRIMARY KEY AUTOINCREMENT, sportslist TEXT)";
char * errMsg;
rc = sqlite3_exec(db, query,NULL,NULL,&errMsg);
if (SQLITE_OK != rc) {
NSLog(#"Failed to create table rc:%d, msg=%s",rc,errMsg);
}
sqlite3_close(db);
}
return rc;
}
//SQLlite database code is used to insert data into the table
-(int) insert:(NSString *)filePath withName:(NSString *)sportslist {
sqlite3* db = NULL;
int rc=0;
rc = sqlite3_open_v2([filePath cStringUsingEncoding:NSUTF8StringEncoding], &db, SQLITE_OPEN_READWRITE , NULL);
if (SQLITE_OK != rc) {
sqlite3_close(db);
NSLog(#"Failed to open db connection");
}
else {
NSString * query = [NSString stringWithFormat:#"INSERT INTO sportsselection (sportslist) VALUES (\"%#\")",sportslist];
char * errMsg;
rc = sqlite3_exec(db, [query UTF8String] ,NULL,NULL,&errMsg);
if (SQLITE_OK != rc) {
NSLog(#"Failed to insert record rc:%d, msg=%s",rc,errMsg);
}
sqlite3_close(db);
}
return rc;
}
- (void)viewDidLoad {
if ( _sports) {
for (int j=0;j< _sports.count;j++) {
int rc= [self insert:[self getSportsFilePath] withName: _sports[j]];
if (rc != SQLITE_OK) {
NSLog(#"Failed to insert record");
}
else
NSLog(#"Record is added");
}
}
}

You should log the return code that sqlite3_open_v2 returned to determine the cause of the error.
One way you could get the error you describe would be if you failed to call createTable before you called insert. Usually you would check for the existence of the file, and call createTable if it's not found. You don't appear to call createTable anywhere.
