There's a wonderful tool in SQL Server that allows you to view the e execution plan for a query. With this, you can analyse to see that you are doing things like indexed queries. We can't help you because we don't have your database schema, and...

To add to what Pete has said: dumping a large amount of unformatted and uncommented code on a site and expecting us to sort it out and convert it for you is just plain rude: to compound that by reposting the same same demand without even showing...
There's no tool that's going to be able to reliably convert a procedure from Oracle to SQL Server. Such tools as exist may get you 60% of the way but the rest is going to be absolute garbage. You are better off working out what the old procedure...

Based on your expected output, you don't want "distinct" records; you want the last record for each order ID. WITH cte As ( SELECT order_id, hierarchyid, itemname, Createddate, ROW_NUMBER() OVER...
You should Group By the first three columns in your results and use Max() of your last column. That should get you what I think you want. Select order_id, itemname, hierarchyid, Max(Createddate) as LastOrderDate From orders Group By order_id,...

Firstly, the "100% cost" just means that your clustered index scan/seek accounts for 100% of the cost of that query. It doesn't mean that the query is less efficient than it would be without that index. Secondly, you need to design your indexes...

Griff's solution is the correct one. When you think about it, SQL Server isn't like other typical server applications that are designed to free memory up. SQL Server is designed to be performant, and to treat the server as its own playground to...
Hi, A customer has a server (Windows Server 2019 with 55 Gb memory) with two instances of SQLServer (SS 2019 Standard edition), one for production, one for testing. The production SQLServer instance ends up occupying almost all the available...
A better solution is to move the test instance to a separate server: that way there is less chance of "interactions" where software being tested affects the production DB. Remember, if the production server is using that much memory, it's for a...
Further to my comments above... In one sense you have already created a temporary table - a table variable scope, like a temporary table, is within the stored procedure (or batch). You cannot use it outside of that scope - just like a temporary...

Storing images directly in a database can lead to increased database size, as you've noticed. To minimize database storage, a common approach is to store the images as files on the file system and store references (relative path) in the database....
