Article Robert Cemper · Mar 19, 2022 2m read Compare Global Write in ePy vs. ISOS/COS This example demonstrates the difference you may experience when you write toGllobals directly from Embedded Python compared to native ObjectScript. To make this demo useful I start 2 background jobs that simply write sequentiallyto a dedicated global. A common control method signals for a synchronous start.Similar a common stop & view interrupts data feeding. That's the principle process: #Embedded Python #Globals #ObjectScript #InterSystems IRIS 2 1 0 228
Question Robert Cemper · Mar 11, 2022 JOB command fails with Embedded Python It sounds strange though it's embarrassing. I have a class with ClassMethods written in ISOS and Embedded Python. The ClassMethods written in ISOS start in the Background as usual. No problems But my #Embedded Python #ObjectScript #InterSystems IRIS 1 4 0 355
Article Robert Cemper · Mar 8, 2022 2m read ePython - mixed or pure ? You may have seen my series of articles on GlobalToJSON closing with Embedded Python.And to me, Embedded means inside a Class and not PEX or other external variants.The first variants showed that ePy is not an ultimate requirement. ISOS/COS may do it as well.Here I try to position ePy inside IRIS. #Embedded Python #Globals #ObjectScript #InterSystems IRIS 6 1 0 338

Article Robert Cemper · Feb 8, 2022 1m read GlobalToJSON-embeddedPython-pure I have created a package to export a Global into JSON object file and to re-create it by reloading from this file embeddedPython refers to the new available technologies. It should be understood as a learning exercise of how to handle the language interfaces. Only Global nodes containing data are presented in the generated JSON file.Differently from the previous example, this one is using embedded Python only, no ObjectScript. Therefore PURE #Embedded Python #Globals #JSON #Python #InterSystems IRIS 8 2 0 557

Article Robert Cemper · Jan 24, 2022 1m read GlobalToJSON-Compact I have created a package that offers a utility to load a Global into JSON object and reverse to create a Global from this type of JSON object. Compact refers to the structure created.Globals nodes are included with data for a fast data load. But also the related code is quite compact. #Globals #JSON #InterSystems IRIS 5 3 0 366

Question Robert Cemper · Jan 12, 2022 SQL LOAD DATA FROM FILE - limits in VALUE clause ? II try to explore the new SQL LOAD DATA feature in SQL comparing it to SQL INSERT I'm stuck at this point: INSERT INTO <table> (columns...) VALUES (.....)allows having not just simple column references but also ALL Standard SQL FUNCTIONS (at least)example: INSERT INTO Test (ShortName,DOB) VALUES (SUBSTRING(Name,1,4),TO_DATE(displayDate,'MM-DD_YYY')) This works perfectly. BUT the same VALUE clause applied to LOAD DATA fails in various ways: #SQL #InterSystems IRIS 1 3 0 254
Article Robert Cemper · Jan 2, 2022 3m read DB Migration using SQLgateway Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS.My personal problem is the use of DBeaver as a migration tool.Especially as one of the strengths of IRIS ( and also Caché) before is the availability of theSQLgateways that allow access to any external Db as long as for them an access usinig JDBC or ODBC is available. So I extended the package to demonstrate this. #Best Practices #Data Import and Export #Docker #SQL #InterSystems IRIS 10 3 2 722

Article Robert Cemper · Dec 25, 2021 2m read AOC2021-rcc After >40 years of writing in-countable lines of code in M*/COS/ISOS (and a bunch of archaic languages)I decided for myself to set a strong signal for the future. We have Embedded Python available(still pre-release)! I just felt it as a sacrilege to ignore this excellent NEW opportunity andstay with the old sermon that I had used for decades. #Docker #Embedded Python #InterSystems IRIS 11 0 0 357
