Hello All,
I am having trouble reading the second table from my database because it
returns nothing even if there is data inside it.
I have a function below
- (NSMutableArray*) getRegions
{
NSMutableArray * data = [[NSMutableArray alloc] init];
const char * sql = "SELECT * FROM Regions ORDER BY RegionName";
sqlite3_stmt * statement;
//prepare the select statement
int returnValue = sqlite3_prepare_v2(mDatabase, sql, -1, &statement, NULL);
DebugLog("return value = %d\n",returnValue);
if (returnValue == SQLITE_OK)
{
//loop all the rows returned by the query
while (sqlite3_step(statement) == SQLITE_ROW)
{
//get the name and the score
int iDen = sqlite3_column_int(statement, 0);
NSString* name = [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 1)];
DebugLog("ColumnName = %s\n",[name UTF8String]);
DebugLog("ColumnID %d\n",iDen);
[data addObject:[NSDictionary dictionaryWithObjectsAndKeys:name,
REGION_NAME, [NSNumber numberWithUnsignedInt:iDen], REGION_ID, nil]];
}
}
sqlite3_finalize(statement);
return [data autorelease];
}
and it works fine but then when I call the second function below after
performing the above function,
- (NSMutableArray*) getProvinces
{
NSMutableArray * data = [[NSMutableArray alloc] init];
const char * sql = "SELECT * FROM Provinces";
sqlite3_stmt * statement;
//prepare the select statement
int returnValue = sqlite3_prepare_v2(mDatabase, sql, -1, &statement, NULL);
DebugLog("return value = %d\n",returnValue);
if (returnValue == SQLITE_OK)
{
//sqlite3_bind_int(statement, 1, regionID);
//loop all the rows returned by the query
while (sqlite3_step(statement) == SQLITE_ROW)
{
//get the name and the score
int iDen = sqlite3_column_int(statement, 0);
NSString* name = [NSString stringWithUTF8String:(char
*)sqlite3_column_text(statement, 0)];
int recordIden = sqlite3_column_int(statement, 2);
DebugLog("ColumnName = %s\n",[name UTF8String]);
DebugLog("ColumnID %d\n",iDen);
[data addObject:name];
}
}
sqlite3_finalize(statement);
return [data autorelease];
}
I get nothing
