Any ideas on how this can be solved?

I need to use it with some Unicode text, in Docker image. And get this error. And documentation says nothing about it.

USER>do $zf(-100, "/SHELL", "echo", "test")

USER>do $zf(-100, "/SHELL", "echo", "test тест")

DO $ZF(-100, "/SHELL", "echo", "test тест")

I know that it works in some Linux environments without Docker, but no idea where is the difference.

Let me introduce my new project, which is irissqlcli, REPL (Read-Eval-Print Loop) for InterSystems IRIS SQL

  • Syntax Highlighting
  • Suggestions (tables, functions)
  • 20+ output formats
  • stdin support
  • Output to files

Install it with pip

pip install irissqlcli

Or run with docker

docker run -it caretdev/irissqlcli irissqlcli iris://_SYSTEM:SYS@host.docker.internal:1972/USER

Connect to IRIS

$ irissqlcli iris://_SYSTEM@localhost:1972/USER -W

So, I know that I can return a SQL Error message from my SQL Procedure written in ObjectScript, with code like this

$ cat <<EOF | irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER
 SET %sqlcontext.%SQLCODE = 400
 SET %sqlcontext.%ROWCOUNT = -1
 SET %sqlcontext.%Message = "test error message"

CALL test();

[SQLCODE: <-400>:<Fatal error occurred>]
[Location: <SPFunction>]
[%msg: <test error message>]

But I did not find how to do it with Python. I can't find %sqlcontext variable available there

So, the next year will bring us a new way of installing IRIS. Always keep in mind that you have to bring your own web server. No matter how many instances of IRIS you have on your local machine. Or if you work in Docker, always keep in mind a bit more complicated configuration.

And I now want to understand the costs of this decision for end-developers like most of here.

I have table

        name VARCHAR(50) NOT NULL, 
        parent VARCHAR(50), 
        PRIMARY KEY (name), 
        FOREIGN KEY(parent) REFERENCES nodes (name) ON UPDATE cascade

I put some data

INSERT INTO nodes (name, parent) VALUES ('n1', NULL);
INSERT INTO nodes (name, parent) VALUES ('n11', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n12', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n13', 'n1');

Let's delete all


Nope, no way.

SQL Error [124] [S1000]: [SQLCODE: <-124>:<FOREIGN KEY constraint failed referential check upon DELETE of row in referenced table>]
[Location: <ServerLoop>]
[%msg: <At least 1 Row exists in table 'SQLUser.nodes' which references key 'NODESPKey2' - Foreign Key Constraint 'NODESFKey3', Field(s) 'parent' failed on referential action of NO ACTION>]

I have a table, with autoincremented id

    name VARCHAR(30) NOT NULL,
    PRIMARY KEY (id)

I can add a new item there with an explicit id

INSERT INTO users (id, name) VALUES (2, 'fred')

And while my id is autoincremented, I can omit it

INSERT INTO users (name) VALUES ('ed')

So, this time, I don't know the id, and I want to somehow get it.

I could do it with LAST_IDENTITY() function, but it just uses %RowID, and have no relation to the primary id

A new release of ZPM has been published 0.5.0

New in this release

  • Added support for Python's requirements.txt file
  • Using tokens for publishing packages
  • Fixed various issues

Python's requirements.txt

Now, if your project uses Python embedded and requires some Python's dependencies, you can add requirements.txt file to the project, as usual for any Python project, file have to be in the root of a project next to module.xml. And with load command or install command, ZPM will install dependencies from that file with using pip.

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');
