The incoming request has too many parameters. The server supports a maximum of 2100 parameters

Question

I have this seemingly simple linq-to-sql query that searches some data in several columns; something like this:

List TheTableIDs = list of IDs (s         


        

Answer 1

I was getting this and was I no way using 2100 parameters! Something else was afoot.

On closer examination I found that I was adding supposedly 5 parameters in a loop, but the source object was not getting cleared, so the list of object to insert was just getting bigger and bigger.

 Dim reportNum = 1

                For Each report In wwo.wwoWeatherReport.listOfForecasts
                    'whack these into the  regionsAndCountries
                    db.addParameter("@forecastAirTemp" & reportNum, report.listOfhourlyForecasts(0).hourlyForecast_tempC)
                    db.addParameter("@forecastRainFall" & reportNum, report.listOfhourlyForecasts(0).hourlyForecast_precipMM)
                    reportNum = reportNum + 1

                Next

I had to Dim a new wwo object beforehand and it sorted it

Dim wwo As New wwwoManager

Dim reportNum = 1  ...
