What is "hexvalue" here??
You are passing only one parameter to your INSERT statement while mentioning it as two.It astounds .. !

Hi,
why don't you define a default value of "getdate()" for the time field at the database level ?
You can ignore this field when inserting new data to the table. It automatically gets server time of insertion.

Hi,

For consistency I would assume you require the server time and not the client pc time.

All you need to do is set the Time on your table with a default of Getdate().

HI,

Here you are passing only session values.

string query = "insert into Table_1(SensorValue,Time) values(" +hexValue+ "," +DateTime.Now.ToString("HH:MM:ss")+")";

Thanks

Paramatarized Queries are the way to go. We should NEVER suggest inline values like this. They are nothing but an invitation to SQL injection.

All you need to do is set the Time on your table with a default of Getdate().

In this way you don't pass any value on insert.
