Well I found others that might have had a similar questions,īefore I go on. So my question has gone from a very confusing 'works sometimes' situation to a basic 'cannot communicate on port 1434' situation. Once I did an iisreset it 'forgot' what port number was used, so had to make a request on port 1434, which for some reason doesn't work. Adding the port number to that connection string as well as the ones stored in web.config allowed all the sites to work.Īdditionally, the reason that iisreset had an effect is that once IIS knows the port number that SQL is using, it seems to 'remember' the port number, and so it no longer has to rely on using port 1434. The other sites didn't work when port number was specified because I hadn't added the port number to this connection string in nfig. The site that worked when a port number was specified did not use this connection string, so worked. Some of the mystery is solved - The reason that some sites could connect and some couldn't is that there was an additional connection string stored in the nfig file that two of the sites were using. You're able to leverage the UNIQUE clause here since your GUID guarantees it, which can slightly help performance of the index as well. The exact index recommendation in that case would then be CREATE UNIQUE CLUSTERED INDEX IX_IndexName ON TableName (OrderId, ChangeDateTime). There's also not much inherent difference between CLUSTERED and NONCLUSTERED indexing in your case, but if you have the luxury, and your examples are the most common type of querying that will be done, then go with the CLUSTERED index as that will provide you greater flexibility in the future with minimizing performance hits should you end up needing to SELECT other fields. There's probably going to be no difference by adding an INY IDENTITY column to use in your index vs using the existing DATETIME field, as they both take up the same storage anyway. You'll still see improved query performance with the index on it. GUIDs are obviously not the most ideal column to index on because of their data size, and more so because of their randomness resulting in higher fragmentation, but if it's all you have to work with then it's better to index it than not. Slightly different (but probably materially the same) suggestion from Akina would be to index on (OrderId, ChangeDateTime) INCLUDE (Status) since you're only selecting Status never filtering on it directly. Ladies and gentlemen, start your semi-colons!īad Habits to Kick : Using EXEC() instead of sp_executesql Protecting yourself from SQL Injection - Part 1 / Part 2 Now, when you call it, specify the schema too, in both places, and specify the parameter name too, e.g.:ĮXEC dbo.TableSelect = N'dbo.Waterford' īad Habits to Kick : Avoiding the Schema Prefix SET = N'Update ' + + N' Set Internet = 1' ĮXEC sys.sp_executesql sp_executesql preferred over EXEC() which can at least somewhat help avoid SQL injectionĭECLARE NVARCHAR(4000) - should always use Unicode here too

should at least validate that the is valid

Microsoft ODBC Driver 13.Something seems really, really, really bad in this design.ĭo you really have a large number of tables that have a column called Internet? What does that column even mean?ĭo you really want to call this stored procedure such that it updates every row in the specified table? Why? You don't have a one-row table for every location / city / room, do you? Why?Īnyway, there are a couple of problems in your code allow me to suggest a re-write, if you can't consider a complete redesign.ĪLTER PROCEDURE dbo.TableSelect - always use schema NVARCHAR(512) - this must be a Unicode data type!
