I have the following line code used to retrieve data from database: DataTable newEquipmentTable

  • 0

I have the following line code used to retrieve data from database:

DataTable newEquipmentTable = database.Connection.RetrieveData(database.AdapterType, string.Format("SELECT ID FROM Equipment WHERE Name = '{0}' AND CreatedOn = '{1}'", equipment.Name, equipment.CreatedOn.ToString("yyyy-MM-dd HH:mm:ss.fff")));

It returns an error saying “The conversion of varchar data type to a datetime datatype resulted in an out-of-range value”

When I make a direct consult, using the following query it returns the expected result.

SELECT ID FROM Equipment WHERE Name = 'aa' AND CreatedOn = '2012-04-17 19:42:49.650'

What am I doing wrong?

    Please note that SQL’s datetime type cannot hold values prior to 1753-01-01.

    Just inspect the SQL string with the debugger before it is used to query the database in order to find the problem.

    However, the best thing to do is to use a parameterized query (like in this example); otherwise you’re vulnerable to SQL Injection.
