string[] names = { " 'a.jpg', 'b.jpg','c.jpg','j.jpg' "};

for (int j = 0; j<names.length;>
{

OleDbCommand sqlcmd = new OleDbCommand("delete from table1 where column_name not in (" + names[j] + ")", sqlconnection);

sqlcmd.executenonquery();

}

// this code will delete multiple records excluding the parameter values, in this case (names array).
you can exclude or include as many values as many you want.

Solution 1

I think you need to use comma (,) in the string

C#

string names = "'a.jpg', 'b.jpg', 'c.jpg'";

OleDbCommand sqlcmd = new OleDbCommand("delete from table1 where name not in (" + names + ")", sqlconnection);

sqlcmd.executenonquery();
