如何将nsmutable数组添加到sqlite数据库表中

Question

如何在sqlite数据库表中添加nsmutablearray？有人可以帮我编码吗？

Answer 1

You can use :

 for (int i = 0; i < [mutArray count]; i++)
    {
       NSString *string = [mutArray objectAtIndex:i];
       // insert query
       insert into table_name ('string') values(column_name);
    }

Answer 2

Use looping Controls to sort the array and insert each values

Example:

for(int itemIndex = 0; itemIndex < [yourArray count];itemIndex++){

     NSString *myname = [yourArray objectAtIndex:itemIndex];

    //insert myname to database.

}

To retrieve , you can use the sample below code

        if(sqlite3_open([path UTF8String], &dataBase) == SQLITE_OK)
        {
            NSString *query = [NSString stringWithFormat:@"select name from syncTable where Crc = %d",crc];         const char *sql = [query UTF8String];
            sqlite3_stmt *statement;
            if (sqlite3_prepare(dataBase, sql, -1, &statement, NULL) == SQLITE_OK)
            {
                char *name;
                unsigned int value;
                while(sqlite3_step(statement) == SQLITE_ROW)
                {
                    name = (char *)sqlite3_column_text(statement, 0);   
                    [yourArray addObject:[NSString stringWithUTF8String:name]];

                }
                sqlite3_finalize(statement);
            }
        }

Here is a list of tutorials for using sqlite with iphone. Its not a matter of simulator or device. It will work fine with simulator also.

Create your db structure properly and work based on this tutorials.

Or

I'd recommend you to use Core Data if you want you work with databases on iPhone OS.

This tutorial should match your app quite well. Please ask if any more questions.
