#SQL

Haven't found this in the documentation. I want:

&sql(SELECT name INTO :var FROM :table)

Is it possible?

I have a task that has been working successfully for some time now but when I attempt to recompiled I get this error:

We don't often use SQL within our org, which is mostly due to the performance issue we experience due to the quantity of data we are reviewing.

Aside from the standard performance measures for non-Caché databases, are there any recommended approaches when querying large tables?

The table would have roughly 50M records, but there are not a finite amount of sub-nodes.

Hi all.

I have some problem with getting data from external source (PostgreSQL) via JDBC and load it in DeepSee and I resolved some problems while writing this question :)

So..Below I proved my steps of working:

Following the documentation to insert into tableA from tableB in the SQL query box from the Management Portal :

INSERT INTO tableA (col1, col2)
SELECT col1, col2
FROM tableB

This straightforward query raises the following error :

I have table

CREATE TABLE nodes (
        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

DELETE FROM nodes;

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 need to show the absence of data, so I have to join the list of predefined values with a result of a select statement.
However, it seems like Table Value Constructors in JOIN are either not supported, or I do not understand the syntax.
Basically, I am going for something like this:

Select v.valueId, m.name 
 From (values (1), (2), (3), (4), (5)) v(valueId)
     left Join otherTable m
        on m.id = v.valueId

Is it supported in Cache SQL or not?

Is there some generic way to output a %SQL.StatementResult to CSV?

Hi:

We added a column to a table as follows

Property SentTime As Ens.DataType.UTC;

And the code to populate this

Hi folks,

I made a solution (https://openexchange.intersystems.com/package/iris-pretty-gpt-1) and want to use it like

I'm using Cache SQL and want the ability to choose a specific index.

I've boiled the problem down to one table and simplified the query down to

SELECT *
FROM Registration.PatResp
WHERE SchedApptNum=8450022

SchedApptNum is indexed, but instead of using that column, "Show Plan" indicates that it's looping through the entire Registration.PatResp table on Id (the primary key for the table).

I've done a tune-table with no change.

I'm breaking my head trying to figure how to solve this issue.

Hello,

I tested the query on the Config.ConfigFile table of the Namespace %SYS, it returned 3 lines and a fatal error:

I have been using the query below and it was working fine but now it's giving a SQL error. There were no changes made that could cause this to stop working. There is no Field 'APPLICATIONID' in the table.

QueueSQL=select distinct (convert(char(5),SkillsetID)+'='+Skillset) from iagentbySkillsetStat where ApplicationID > 10000
QueueMappingSQL=SELECT DISTINCT (convert(char(5),SkillsetID)+'='+Skillset), SkillsetID FROM iagentbySkillsetStat iagentbySkillsetStat WHERE (iagentbySkillsetStat.ApplicationID>10000)
