Question

I need to delete multiple rows from my database table.
This is my code for deletion

String[] paragraph;
.....
//here you can to put various strings within it (1 or more)
.....
db.delete(mytablename,"Paragraph = ?",paragraphs);

It works with 1 string, but it doesn’t work with more strings.
Can someone help me, please?

Here there is the error shown by LogCat:

Answer 1

use this way:


for(int i = 0 ; i < paragraphs.lenght;i++)
{

db.delete(mytablename,"Paragraph ='"+paragraphs[i]+"'",null);
}
