The highest number I was able to allocate is 3 below the maximum value of a 64-bit integer, which was 9,223,372,036,854,775,805 and you would get an error for the next value: If you would ever reach the maximum value, the manual fix is to set the next value to be -9,223,372,036,854,775,807.
It is possible to fetch the next Rec Id in the sequence by a SQL Server stored procedure on the AX DB: Unfortunately it has limitations, because the AX Application Object Server fetches Rec Ids ahead and stores it in a cache to speed up inserting new records in the table.
As a generalization, the DBA ought to start with a list of roles users can play in the enterprise and create a script for the privileges each role needs.
A new user can then be assigned a role and you do not have to repeat the script over and over. One user might have read the spec “Employees must be over 21 years of age to serve alcohol” to mean strictly over 21 as of today or can they pour a drink on their 21-st birthday? This technique becomes more useful as the SQL becomes more complex.
One query uses an infixed JOIN operators and another uses a s, write them and then see if you can find places where they would make the code easier to read and maintain.
As an example, our hotel application will probably need to find vacant rooms by calendar date, compute an occupancy ratio by calendar date and other basic facts.
This requirement keeps popping up on the Community Forums by people who are not familiar of how Microsoft Dynamics AX works, typically for third-party integration, data warehousing and reporting scenarios.
The most common offender is the “Volkswagen” coder who prefixes or suffixes the _” in violation of ISO-11179 rules. This is as silly as prefixing every noun in a novel with “n_” so the reader will know that the word is a noun in English grammar.Joe Celko tackles an introduction to the subject, but there is something about the topic that makes it likely that even the experienced developer will find out something new from reading it.is a virtual table, defined by a query, that does not exist until it is invoked by name in an SQL statement.While I know of no formal proof, I suspect that determining if a complex query resolves to an updatable query for allowed sets of data values possible in the table is an NP-complete problem. Going back to my Y2K consulting days, I ran into a version of such a partition by calendar periods.The triggers gives the user the effect of a single table, but there can still be surprises. Their Table C was set up on Fiscal quarters and got leap year wrong because one of the fiscal quarters ended on the last day of February.
