#Data Import and Export

2

This topic unites posts which describe approaches, tools, and solutions to import and export data into InterSystems IRIS and other InterSystems Data platform products: CSV, JSON, SQL, flat files, binary files, globals, streams, etc.

Hi,

I have a process that is importing lots of data from an external file, but every now and then I come across a STORE error.

I know that the STORE error is occurring in the %Save method of the class but I know very little else and I think its something to do with a lage amounts of Related Objects.

Is there a method of finding out more information regarding this error i.e. which actual object was being saved etc etc.

Thanks

Jim

Hi,

I am brand new to Cache and have been tasked with extracting data from the dB. I see that there are a bunch of tools that can be used to extract via SQL Server statements. DataGrip and DBeaver to name 2. I've gone through some documentation and it doesn't look as if SSMS can connect directly. Is there a preferred extraction tool that anyone can recommend. Does the Cache dB have anything built in where I can access the data while seeing a visual of the tables/schema?

Thanks for any advice,

Hi,

I exported selected globals from a Cache 2017 database into a single 4 Gb gof file. Now I tried to import from this file via Management Portal on a different machine . Only about half of the globals was imported and my attempts to select additional globals led to nothing, no new globals have been imported. Well, obviously I am mildly curious what's going on and how can I see the corresponding error which did not appear in the Import window but I can also shrug it off and consider what should I do next.

Hello,

We are trying to migrate all our production to new IRIS servers. To test everything is working fine, and to be able to script the process, we want to import the data into new IRIS servers using a backup file (created with ^BACKUP). But we've found that IRIS doesn't recognize Ensemble backups so we can't import it using ^DBREST :-O

Any of you know how to import in IRIS an Ensemble backup file?

Thanks a lot,
David

Hello. When you export and then import a table of data, is the import smart enough to figure out if a row already exists in the new namespace, and if so update the row rather than just save/add the row?

For example, we have a table in DEV, and the same table in QA. The DEV table has more fields than QA. When we moved up the class, the field definitions went with the table into QA, so now the table definition is the same in both.

Explicit FTPS in Cache

We use the %Net.FtpSession class to perform FTPS file transfers. This has worked fine with Implcit FTPS servers but crashes when trying to connect to an Explicit FTPS server. Explicit FTPS has a slightly diffferent negotiation in the intitial connection and different ports.

Has anyone gotten Explicit FTPS working with the Cache classes?

Hi

We have Edge Production where we uploading flat files clinical data, and during testing we do this for several rounds load data, test them and reload them. So everytime we have to generate differnet patient data or change MRNs etc. So request is is there a command to delete patient records that will remove from the tables, and delete reference in the registery as well.

Any guidance that you follow for testing backload data and delete loaded data, pls share

Hi everyone. I'm new to cache, and i was looking for a command who reads a .txt file and store the informations in variables. I've found on the documentation the EnsLib.SQL.SNapshot class, and, even if i'm not sure if that's what i need, when i run the code it says that the class doesn't exist, but i couldn't find the right superclass to extend.

JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

Hello,

Our team is looking for a way to export all of our Cache SQL tables into Microsoft SQL Server. I have only found a method to export one table at a time into an ASCII file. We have over 170 tables so this would be very tedious and time consuming. Is there a way to directly export from Cache to SQL Server. Alternatively is it possible to export the entire database in a single shot or even multiple tables to text files?

Thanks!

SQL LOAD DATA date values

I have csv date file with date values like this "4/10/2021" for April 10, 2021. I defined a table with this property: Property TranDate As %Library.Date.

I capture error

[SQLCODE: <-104>:<Field validation failed in INSERT, or value failed to convert in DisplayToLogical or OdbcToLogical>] [Location: <ServerLoop>] [%msg: <Field 'dc_data_finance.transact.TranDate' (value '4/10/2021') failed validation Field ...

I do not really want to change TranDate to %String. How can I import "4/10/2021" into %Date property?

Like if ^Custom == ^[Drone]Custom ??

After linking in Oracle Table with Field Column's Data Types of NUMBER, my updates into these table fields are resulting in data that is being rounded to 2 decimal places. I insert a record with 1234.1234 and 1234.12 is stored.

It appears Cache xDBC might be manipulating my values prior to sending to Oracle. Is there a setting or system parameter that is controlling this? If so, is there a way to relax this from occurring so the values I send are being stored in Oracle with the same values?

%File Delete not Working

Hey there,

I'm writing an import Routine to read files into a global. The code is working fine except for the 'Delete' command. The files are being imported, copied but not deleted. Maybe someone has an Idea what ist happening.

I get the low level return value of -32 but i couldn't find anywhere to show me what that actually means. And my Caché version doesn't support the $ZU command.

Here's the Code
