class Example15_3 {
static void Main(string[] args) {
//SqlConnection cs = new SqlConnection(“Data Source=I7-ACER-PC\\SQLEXPRESS; Initial Catalog=FinancialDemo; Integrated Security=SSPI; Persist Security Info=false; Trusted_Connection=Yes”);
// SqlConnection cs = new SqlConnection(“Server=localhost;Database=FinancialDemo;User Id=sa;Password=hello123;”);

//this one connects but user is not valid
//SqlConnection cs = new SqlConnection(“Server=localhost;Database=FinancialDemo;User Id=sa;Password=hello123;”);

SqlCommand cmd = new SqlCommand();
SqlDataReader reader;

cmd.CommandText = “SELECT * FROM Tickers”;
cmd.CommandType = CommandType.Text;
cmd.Connection = sqlConnection1;


reader = cmd.ExecuteReader();
// Data is accessible through the DataReader object here.

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at
