Hello ;

I'm trying to insert date value to Sql server DB by using vb.net .

here is the sql command

VB

"INSERT INTO [Orders]([ProductID],[CustomerID],[EmployeeID],[OrderDate],[Quantitiy],BillNuber) VALUES (" & ProductID & "," & CustomerID & "," & EmployeeID & "," & System.DateTime.Now.ToString((" yyyy-MM-dd")) & "," & Quantity & "," & billnumber & ")"

I also used Now.tostring("yyyy/MM/DD") , Today.tostring("yyyy/MM/DD")

the problem when i Use now() error message pops "error near '2'"
and even if there is no error and when i use today() or system.datetime , when i check the database the date look like "1900-01-01 00:00:00.000"

can you help me ?

What I have tried:

now()
today()
Now.tostring("yyyy/MM/DD")
Today.tostring("yyyy/MM/DD")

Solution 1

The generic date format which works regardless of the local for SQL Server is "yyyy-MM-dd" don't use / for a separator.

Also in string form add " quotes around the date.

Better still don't use string concatenation and use SQLParameters instead :
