问题 I have looked into Cast and Convert, but I cannot find a way to do this. I need to convert four digits into an hour format. For instance, 0800 would become 8:00 or 1530 would become 15:30. I cannot use functions, I'm using a InterSystem's CacheSQL. Any suggestions? Thanks in advance! EDIT: If it is any more convenient, I can just divide the four digits by one hundred to get values like 15 from original 1500, or 8.30 from 0830. Does this make converting to hour:minute format easier? 回答1: For

问题 How to take screen shots in windows system using inter systems cache? 回答1: Cache doesn't have any built-in way to directly take a screen shot, so the closest you could come is to have a Caché process call something that does know how to take a screen shot. The ways to call out from cache are documented on the Intersystems web site and this same documentation is usually included in a Caché install. The simplest option (and you don't give enough information to know whether that will work) is

问题 Is it possible to write ObjectScript method, which will create new class in namespace and compile it? I mean programmatically create new class and store it. If so, can I edit this class using ObjectScript later(and recompile)? Reason: I have class structure defined in string variable and I need to add new class to namespace according this string. 回答1: Nothing is impossible. Everything in Caché can be created programmatically. And, Classes is not a execution. There are at least two ways to do

问题 In my project I'm using a integration of Intersystems Caché with Java by a Java Gateway, it's basically maps JARs and create a class proxies in Caché to access Java classes into the JAR. A class in Java has a parameter of type FileInputStream , my question is how I should send this parameter Caché proxie ? What type of data in Caché represent the FileInputStream in Java? Regards, Lucas Boeing Scarduelli 回答1: When you create proxy for that java, should be created cache-class for

问题 I have a data source where the dates come back like this: 20150614140520-0500 How can I display this better? It doesn't actually have to be converted technically, this is just for reporting. Ideally it would output 2015-06-14 2:05 PM (EST) but I also want the statement to be as simple as possible so the timezone offset and 12hr time are optional. I tried CAST ('20150614140520-0500' As Date) but it returns null I also tried CAST (LEFT('20150614140520-0500',14) As Date) as well as some other

问题 Consider, i have a global ^TEST and i want to replicate/have a copy of the same in ^TEST2 automatically.Each action set or kill on ^TEST should reflect on ^TEST2 automatically. 回答1: The only way to make sure that this can happen 100% reliably is to create a Journal Filter which watches for changes to ^TEST and then manipulates ^TEST2 appropriately.

问题 I use InterSystem's cache JDBC driver to query the "database dictionary" in order to retrieve source code from classes. I have this SQL query: final String query = "select id, super" + " from %Dictionary.ClassDefinition" + " where System = '0'" + " and name not like '\\%%' escape '\\'" + " and deployed != 2"; Right now, the user performing this query has %All as a role, which is of course not a good thing. I try and reduce the privileges of this user to the strict minimum necessary. I am
