Question

I have a database in SQLite, and a table named xyz which is empty. I want to import data from a csv file into that table.

Now, when I try to import csv file, it is asking me to import it into the main table, but I want to import the data into my xyz table.

How can I do that?

Answer 1

You can do as this way,

First you need to add your csv file in bundle.

Then you can call this method where you want to add data in database from csv

-(void)loadCSVData{
NSString *path1=[[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"YOUR_CSV_FILENAME" ofType:@"csv"]  usedEncoding:&encoding error:nil];
NSArray *messArr=[path1 componentsSeparatedByString:@"\n"];
if(messArr)
{
for(int i=1;i<=[messArr count]-2;i++)
    {
NSMutableDictionary *d=[[NSMutableDictionary alloc] init];
 NSString *StrValue=[NSString stringWithFormat:@"%@",[messArr objectAtIndex:i]];
 StrValue=[StrValue stringByReplacingOccurrencesOfString:@"\"" withString:@""];
 StrValue=[StrValue stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
 //  Here give whatever saperator you need to saperate data
 NSArray *arr=[StrValue componentsSeparatedByString:@","];

 [d setValue:[arr objectAtIndex:0] forKey:@"YOUR_TABLE_FIELD_1"];
 [d setValue:[arr objectAtIndex:1] forKey:@"YOUR_TABLE_FIELD_2"];
 [d setValue:[arr objectAtIndex:2] forKey:@"YOUR_TABLE_FIELD_3"];

  //Here add logic to insert row in your database table
}
}
