#SQL

Let's imagine you have only SQL. You need some table where you should increment value in some property when you update this line.

We have the table

CREATE TABLE "test" (
  "identifier"   VARCHAR(200) NOT NULL,
  "value"        INTEGER,
  PRIMARY KEY ("identifier")
)

I try to create a column with computeonchange.

Its works with CREATE TABLE sql command, but if i use ALTER TABLE ADD COLUMN sql command this computeonchange doesn't works.

any reason why?

example:

CREATE TABLE MyStudents ( Name VARCHAR(16) NOT NULL, surname VARCHAR(16))

alter table MyStudents add column fullname Varchar(50) COMPUTECODE { SET {fullname}={Name}_ "?" _{surname}} COMPUTEONCHANGE (Name,surname)

insert into SQLUser.MyStudents (Name, surname) values ('name1',null)

update MyStudents set name = 'name' where name = 'name1'

SetIdentityInsert call controls the ability of the user to specify a value for the IDENTITY property when saving a new object, a value for the IDENTITY column or an explicit ROWID value in an SQL INSERT. If IDENTITY_INSERT is false and the user specifies an explicit IDENTITY or ROWID value when saving a new object or inserting a new ROW then an error condition is reported.

Setting takes effect immediately and lasts for the duration of the process or until SetIdentityInsert is called again.

My question is how can I change this setting system-wide?

Is there a way or can it be done to use conditional logic in sql like so

 Query Q1(formal as %String) As %SQLQuery [ Final ]
{
    
    SELECT patientnumber,ID, CASE
    WHEN ID = 50 THEN "The is 50"
    WHEN ID = 30 THEN "This is 30"
    ELSE "The quantity is under 30"
END FROM Audit.Table WHERE ID = :formal AND EndDate is null} 

}

Problem

I'm working on exporting data from an Intersystems Cache database through the Cache ODBC Driver. There is a particular table that is giving me an error message. The ODBC Driver crashes and reports an error from the Cache system. I think I was able to trace down where the error is coming from, but I do not know how to debug or fix the error.

The table I am trying to extract is called SEDMIHP.

Here's the Error:

Hi, I'm looking for a way to implement the JDBC pattern "executeBatch" in ObjectScript: https://www.tutorialspoint.com/jdbc/jdbc-batch-processing.htm
