Question

- (NSMutableArray*)getAllDataFromTableUSERINFO:(NSString *)fetchQuery {
NSMutableArray *resultArray1 =[[NSMutableArray alloc]init];
#autoreleasepool {
if (sqlite3_open([[self getDBPath]UTF8String],&database)==SQLITE_OK){
sqlite3_stmt *stmt;
const char *sqlfetch=[fetchQuery UTF8String];
if (sqlite3_prepare(database, sqlfetch, -1,&stmt, NULL)==SQLITE_OK) {
while (sqlite3_step(stmt)==SQLITE_ROW){
RM_USER_INFO *UserInfo = [[RM_USER_INFO alloc]init];
UserInfo.uid=[NSString stringWithUTF8String:(char *)sqlite3_column_text(stmt,0)];
UserInfo.username=[NSString stringWithUTF8String:(char *)sqlite3_column_text(stmt,1)];
UserInfo.password=[NSString stringWithUTF8String:(char *)sqlite3_column_text(stmt,2)];
UserInfo.fname=[NSString stringWithUTF8String:(char *)sqlite3_column_text(stmt,3)];
UserInfo.mname=[NSString stringWithUTF8String:(char *)sqlite3_column_text(stmt,4)];
[resultArray1 addObject:UserInfo];
}
}
sqlite3_finalize(stmt);

Try this function:
static NSInteger DBBUSY;
+(NSMutableArray *)executeQuery:(NSString*)str{
sqlite3_stmt *statement= nil;
sqlite3 *database;
NSString *strPath = Your Database path here;
while(DBBUSY);
DBBUSY = 1;
NSMutableArray *allDataArray = [[NSMutableArray alloc] init];
if (sqlite3_open([strPath UTF8String],&database) == SQLITE_OK) {
if (sqlite3_prepare_v2(database, [str UTF8String], -1, &statement, NULL) == SQLITE_OK) {
while (sqlite3_step(statement) == SQLITE_ROW) {
NSInteger i = 0;
NSInteger iColumnCount = sqlite3_column_count(statement);
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
while (i< iColumnCount) {
NSString *str = [self encodedString:(const unsigned char*)sqlite3_column_text(statement, i)];
NSString *strFieldName = [self encodedString:(const unsigned char*)sqlite3_column_name(statement, i)];
if(!str)
str = #"";
[dict setObject:str forKey:strFieldName];
i++;
}
[allDataArray addObject:dict];
}
}
DBBUSY = 0;
sqlite3_finalize(statement);
}
sqlite3_close(database);
return allDataArray;
}
This may help you :)
