"Okk Bt i wants to know sql queries for add items."
That's easy:
INSERT INTO MyTable (myColumn1, myColumn2) VALUES (MyValueForColumn1, MyValueForColumn2)
If you are using a coding language outside SQL, then you need to look at parameterized queries:
using (SqlConnection con = new SqlConnection(strConnect))
{
con.Open();
using (SqlCommand com = new SqlCommand("INSERT INTO myTable (myColumn1, myColumn2) VALUES (@C1, @C2)", con))
{
com.Parameters.AddWithValue("@C1", myValueForColumn1);
com.Parameters.AddWithValue("@C2", myValueForColumn2);
com.ExecuteNonQuery();
}
}</pre>
