  1. Add DATEADD and DATEDIFF functions to PI SQL Commander

    When any time related functions need to be performed against timestamp columns in PI SQL Commander, one needs to utilize a significant amount of conversions to make this work. For example, if one needs to round timestamps to the nearest minute or the nearest hour, a CASE statement with multiple CASTs needs to be done to get this to work.

    If T-SQL DATEADD and DATEDIFF commands were implemented, this would simplify the query by a significant amount. Similarly, in PL/SQL, the ROUND function is able to round the datetime value directly, which would fit perfectly to this scenario.

    We are planning to add several functions that are equivalent to T-SQL functions. This will make it easier for the PI SQL products to integrate with the Linked Server in Microsoft SQL Server.

  2. Allow PIOLEDB Enterprise to connect directly to a PI Data Archive

    If PI OLEDB Provider is not going to be further developed, allow PI OLEDB Enterprise to connect directly to a PI Data Archive.
    There are times when an SQL type query is needed, but the data structure has not been mapped to an AF server yet.

    We have a new SQL query processing engine under construction. We call it the Real-Time Query Processing Engine, or RTQP Engine. We are targeting improved performance and scalability but we are also improving some of the table designs to make common queries a bit easier. We have talked to many customers about their use cases. It turns out that direct access to PI Data Archive tags is still very important. We also found several hybrid use cases such a summarizing values from a PI tag over the period of an Event Frame, and Kenneth Barber’s excellent example of aligning AF Attributes with PI Point attributes. So, we will be adding direct access to PI tags and data but not in the first release.

  3. Expose Values with Duplicate Timestamps in Transpose Function

    https://pisquare.osisoft.com/message/116957-pi-sql-commander-and-ssrs-how-to-retrieve-multiple-values-with-the-same-timstamp

    In the current implementation of the transpose archive in OLEDBEnt, a user is unable to retrieve data that may exist at the same timestamp as  another piece of data. This is because the time column is treated as the primary key of the transpose table. I would like to be able to retrieve all data using the archive transpose function regardless if timestamps are duplicated.

  4. Add in the Element Hierarchy table information to determine the primary reference of a copied reference element

    When an element is copied as reference (parent-child) elsewhere in the tree it then has multiple parents. One of it is the primary parent. This information needs to be added to the hierarchy tables.

  5. PI OLEDB Enterprise access to AF Tables

    Allow PI OLEDB Enterprise access to AF Tables.  The current workaround is to have the table live on a SQL database and then link to them from AF.

  6. Add 'Time Zone = Server' to PI OLEDB Enterprise

    'Time Zone = Server' is available in PI OLEDB Provider, but has not been added to 'PI OLEDB Enterprise'.
    We have PI Data Archives in multiple time zones and require the ability to select the data in the server time zone.

  7. Allow PI OLEDB Enterprise client to specify which member of a PI Data Archive Collective to connect to.

    Enable functionality for PI OLEDB Enterprise that will allow the client to specify which member of a PI Data Archive collective they wish to connect to. This functionality has already been enabled for PSE and would like something similar for PI OLEDB Ent.

  8. Be able to access the UOM database as tables

    The current method of accessing UOM data is inconsistent with the rest of PI OLEDB Enterprise. Instead of tables, we have functions such as UOMAbbreviation and UOMClassName. Imagine if we had a function for each non-ID column of information that we wanted to access (e.g. ElementName, ElementTemplateDescription). It doesn't make sense. Please make the UOM database available as tables.

    This would also make it easier to manage and clean up the UOM database. For example, an administrator might want to make sure that compound units (e.g. m/s) are named consistently with their base units (e.g. Canadians might change "meter" to…

  9. Automatically update Transpose Function in SQL Commander when referenced Element Template name is updated

    In PI SQL Commander, users can create Transpose Functions that are linked to Element Templates in AF. When the referenced Element Template is renamed in PI System Explorer, the Transpose Function in PI SQL Commander is no longer able to find the Element Template which breaks the Function and underlying Data Table.

    Users are not aware that the Transpose Function or the underlying Transpose Data Table are broken until they attempt to query the Table or Transpose Function. It would be ideal if the Transpose function could either update this reference automatically or if the function referenced the GUID of…
