I have an SQLite database, and when I am trying to get the data from the database, I get the last inserted element repeatedly. How can I get all the elements with no repetition.
The code I've written:
- (NSMutableArray *) gettingData {
sqlDict = [[NSMutableDictionary alloc] init];
membersInfoArray =[[NSMutableArray alloc开发者_StackOverflow]init ];
[self checkAndCreateDatabase];
if (sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
{
const char *sql = "select * from ProductList";
sqlite3_stmt *selectstmt;
if(sqlite3_prepare_v2(database, sql, -1, &selectstmt, NULL) == SQLITE_OK)
{
while(sqlite3_step(selectstmt) == SQLITE_ROW)
{
NSString *prdbcode = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 0)];
[sqlDict setObject:prdbcode forKey:@"Barcode"];
[prdbcode release];
NSString *prdname = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 1)];
[sqlDict setObject:prdname forKey:@"ProductName"];
[prdname release];
NSString *prdDesc = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 2)];
[sqlDict setObject:prdDesc forKey:@"ProductDescription"];
[prdDesc release];
NSString *prdstatus = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 3)];
[sqlDict setObject:prdstatus forKey:@"ProductStatus"];
[prdstatus release];
[membersInfoArray addObject:sqlDict];
[sqlDict release];
}
}
sqlite3_finalize(selectstmt);
}
sqlite3_close(database);
return membersInfoArray;
}
I am retrieving the data as follows:
NSMutableArray *sqlArray = [sqlViewController gettingData];
Thank you.
Just Declare your array globally instead of declare locally in your method. Your problem will resolved.
