find the index of row in datatable,mysql

[rajeswari02]

hi,

i want to know the index of row( i know the primary key column value, based on that i want to know the index of that row in data table)

here is my code i tried:
but it's giving error as:table doesn't have a primary key. c#

But my datatable in Mysql database is having primary key column.

using (MySqlConnection con = new MySqlConnection(ConnectionString))
                {
                    String query = "select * from customer";
                    MySqlCommand command = new MySqlCommand(query, con);
                    MySqlDataAdapter da = new MySqlDataAdapter(query, con);
                    da.Fill(dt1);
                    totalRowsInDB = dt1.Rows.Count;
                    Startindex = dt1.Rows.IndexOf(dt1.Rows.Find(startNo));
                    Endindex = dt1.Rows.IndexOf(dt1.Rows.Find(endNo));
                    con.Open();

here startNo=1002 and endNo=1005
which i have in database primary key values

use:

select @a:=@a+1 ROWNUM, * from .....

you can reset '@a' using:

set @a=0
