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 0 218
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 2 649
