wpf - How to retrieve values from multiple rows of the same column in SQL Server -
i need search booked patients given date. don"t know error in code is. retrieve 1 row table. please help
string sp = textbox1.text; sqlconnection con1 = new sqlconnection(); con1.connectionstring = "data source=swathi-pc\\nm;initial catalog=clinic;persist security info=true;user id=sa;password=sqlpass"; con1.open(); string query = "select booking_dt,name patients1 booking_dt=@dt "; sqlcommand cmd = new sqlcommand(query, con1); cmd.parameters.add(new sqlparameter("@dt", sp)); sqldatareader dr = cmd.executereader(); if (dr.read()) { listview1.items.add(dr[1].tostring()); }
i'd it's your
if (dr.read()) { }
block running once. don't know specifics of whichever language you're using, i'm guessing need along lines of
while (dr.read()) { listview1.items.add(dr[1].tostring()); }
which should iterate through dr.
