将Guid传递给SSRS 2008 Url Access参数

Question

I am trying to use URL access to pull down some reports from sql server reporting services 2008. One of the parameters I need to pass is a Guid. When I just paste the guid in to the url as

&LoggerID=CD4869DC-68B8-4513-B3C6-0E6DD9F74380

I get the error: Default value or value provided for the report parameter 'LoggerID' is not a valid value. (rsInvalidReportParameter)

I have tried single quotes and brackets and curly brackets. What am I missing?

Answer 1

I just ran into this problem and it turned out to be a problem with capitalization of the letters inside the Guid.

Since SSRS doesn't understand uniqueidentifiers it just treats them as strings. So if you have a 'Get values from query' option for that parameter, the url parameter you pass in must match the query results character for character. Meaning matching capitalization

It failed when on the url I had

&entityIdentifier=75745B11-09B8-4BF6-98EF-F3E8A2ACEC05

but worked when I changed that to

&entityIdentifier=75745b11-09b8-4bf6-98ef-f3e8a2acec05

Answer 2

It turns out that when you set the available values for a parameter as "Get values from Query" it won't accept the guid in the URL. As soon as I turn this off, it works. This only seems to be a problem for GUIDs as I am doing this with an integer and it works fine.

Related: 2008 still uses string as the parameter type.

Answer 3

Passing a Guid in that format to one of my own reports works fine.

I notice that your error message talks about a parameter called "LoggerID" yet your URL is using "guid" as the parameter name. It's not something simple like that?

Also note that (in my experience) SSRS URL parameters are case sensitive. If you are passing "loggerid=..." on the URL and your parameter is called "LoggerID" then you'll get an error message (although it's not the error you describe, so I doubt that's the problem).

Update

I've just had a look at the report of mine in design mode, and it actually uses "String" for the parameter type. In SSRS 2005 there isn't an option to use a Guid. That might be an option for you (change the parameter to string and cast in the query), though it'd be a bit of a hack.

Answer 4

I have had the same problem couple of times, for some reason Guid in URL has to come in lower case otherwise it will not accept it.

Make sure your Guid is formatted to lower case.

Answer 5

I just ran into issues as well trying to pass a GUID parameter in through a URL. My solution was to cast the uniqueidentifier to a varchar(36) in the Dataset query used for the parameter's available values. Then, like others have mentioned, it was necessary to make sure the casing of the GUID in the URL matched the casing in the available values dataset.

Available Values Dataset Query example:

SELECT CAST(MyGuidColumn AS varchar(36)) AS MyGuidColumn, MyLabelColumn
FROM  MyTable
