I have the following class:

Class P.RA.SII.F

Apologies if this isn't the correct forum but here goes..

I'm accessing an Intersystems database from MS SQL Server using Intersystems ODBC driver and using OPENQUERY statement to read metadata of tables using

SELECT * FROM OPENQUERY([<linked server name>], 'SELECT * FROM INFORMATION_SCHEMA.COLUMNS')

but I get an error message saying INFORMATION_SCHEMA.COLUMNS cannot be found.

Intersystems SQL documentation does reference this table so is there some other way to access this table or is it maybe a permissions issue?

Hi,

Can anyone please help me how to use regular expression/wild character on a sql query for a pattern like C00.0 to C00.9, C01.0 to C01.9 and so on until C77.0 to C77.9 .

Thanks for your help

Thanks

Description

This is a template for a FastApi application that can be deployed in IRIS as an native Web Application.

I have to disect thousands upon thousands of strings like this:

96842-2-AEV.00001-63561-001958-100728760I-42

I've been able to pull out the first, second and final segments as separated by hyphens, but now I have a predicament where I need to use the second segment, the 2 shown in the example above, in a join to another table. Problem is Cache apparently doesn't like doing that. Just the same, I have to find a way.

Here's the code I'm using to pull that segment out into as separate field in the query results:

Hi Community!

There are two general ways to execute arbitrary SQL in serverside ObjectScript code: EmbeddedSQL and ObjectScript SQL a.k.a. Dynamic SQL.

E.g. if we want to get the value of the property of instance with a certain ID using SQL we can do:

&sql(SELECT Name INTO :name FROM Sample.Person WHERE ID=1)

write name

Same result with %SQL.Statement:

set rs=##class(%SQL.Statement).%ExecDirect(,"SELECT Name as name FROM Sample.Person where ID=1")
  do rs.%Next()
  write rs.name

I am trying to create a Procedure in Caché, but this message is showing:

<UNDEFINED>frmit+118^%qaqpsq *mt("v",1)

This is the procedure:

CREATE PROCEDURE testebi.sp_cargainicial()
BEGIN
INSERT INTO testebi.Fato_Atendimentos (
PK_OsProcedimento )
SELECT ID
from dado.TblOsProcedimento ;

method Export(savertn As %Boolean = 0) [ Language = objectscript ]

On an IRIS system, we expect the default string collation for SQL columns to be SQLUPPER. This means WHERE conditions will be case-insensitive. However, when I make a WHERE condition on a SQL procedure that returns a string, it's case sensitive.For example:

Instead of building a BP to execute stored procedures just to insert the data, I figured I would give Linked Stored Procedures a try since all I need to do is insert the data. I have proved in our MS SQL Development environment that it is possible, so I through I could just repoint the Linked Stored Procedure

Hi All,

I have a general query in regards to developers experience on extracting data from cache databases and the most efficient way to do so. I work with a number of clients who have applications with cache databases and require the data off the host system and onto data warehouse platforms for research and analysis. Often they require the data in source state which means the extracts are often simply a table scan of the entire database table without any aggregation or manipulation.

We use ExecureProcedure() to execute a stored procedure which returns a result set. But we see lot of "Invalid cursor state" errors when the result set is empty. The connection to SQL server database is made through ODBC.

ERROR #6022: Gateway failed: Fetch. + ERROR <Ens>ErrGeneral: SQLState: (24000) NativeError: [0] Message: [Microsoft][ODBC Driver 11 for SQL Server]Invalid cursor state

Here is the code snippet from the business operation class which uses EnsLib.SQL.OutboundAdapter

I have an ObjectScript class with a Log property of type %Stream.GlobalCharacter. I need to search the end of each of the logs - is there a way to extract the last 10 lines of the Log stream for each object via SQL? Or is my only option to write an ObjectScript routine to walk the table and inspect each Log property one by one?

Thanks!

How to read the HL7 V2.5 messages irrespective of message type to Iris database ?

Source system sends HL7 messages of multiple message types to Intersystems through TCP and these messages are to be inserted/read into iris SQL database.
