I'm developing an integration between Caché servers by ODBC conection, and I have the following problem.

In this call:

call COSClass_Methode('222169^^98^155^64530^06:30^021542987897458855441112877855^1^0^281992^GC')

the ODBC driver is truncating the string to 50 characters.

If I run this same command with $system.SQL.Shell(), this doesn't occur.
I did a test creating several parameters for COSClass_Methode, and they all have a 50 character limitation.

ODBC Providers for SQL Server

Where can i get the latest odbc providers from SQL Server 2012/2016?

I see some posts on line to an ftp site out there but I am unsuccessful at getting access to it. I have a version loaded on my server but get errors when querying cache'.

"[Cache ODBC][State : 22005][Native Code 22005]"

Any help would be appreciated.

the one we have might be version 2014.01.05851 64 bit (would that make sense?)

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.

Customer is experimenting with %vid variable for selecting row numbering for sql queries. Basically he's trying to implement paging functionality.

He is confused that select %vid from (select ...) returns dummy number whilst select *,%vid from (select...) returns correct data.

If I have defined a class query in one of my classes and I want to use that query from a method of another class, what are the pros and cons of using the %SQL.Statement interface versus the %Library.ResultSet interface?

I believe %SQL.Statement is the newer interface.

So if the old way is:

USER>s rs=##class(%Library.ResultSet).%New("%Library.File:FileSet")
USER>s sc=rs.Execute("c:\s\","*.txt")
USER>w sc
USER>while rs.%Next() {w !,rs.Data("Name")}


then the new way is:

I want to override the Get and Set methods of a class property. The class maps to a pre-existing global. The property is defined like so:

Property Invalid As %Library.Boolean;

with the property mapping to a node like ^GLOBAL(Code,"INVALID")=1
Code is a property in the same class.

The value can be 0 or 1 or the node might not exist. When it doesn't exist I want the value of the SQL field to come out as 0 (false).

Whenever I try to run a simple query on a production database table, I get a timeout 504 error. I'm using the SQL interface in Ensemble. One of the queries is a simple SELECT TOP 10. Even SELECT COUNT(*) gives a timeout.

I have tried to run the SQL Runtime Statistics, but this gives me a timeout as well.

Does anyone have an idea where I might look to find what is causing this?

Thanks in advance,

Best regards

Glenn van Bavel,

I'm running this code in our application, and in the terminal:

>set query="SELECT * FROM PMG_Data_Private.RemitInstance WHERE (VoucherNumber %INLIST ? SIZE ((10)))"

>set tRS = ##class(%ResultSet).%New("%DynamicQuery:SQL")

>set ok=tRS.Prepare(query)

>d $system.Status.DisplayError(ok)

ERROR #5540: SQLCODE: -76 Message: Cardinality mismatch between the SELECT-list and INTO-list

Last week, we announced the InterSystems IRIS Data Platform, our new and comprehensive platform for all your data endeavours, whether transactional, analytics or both. We've included many of the features our customers know and loved from Caché and Ensemble, but in this article we'll shed a little more light on one of the new capabilities of the platform: SQL Sharding, a powerful new feature in our scalability story.

I am trying to fetch the data from cache database. But i got the error like "CSP application closed the connection before sending a responce".

Below is the query.

FROM SQ.CBPhoneResult_View Where PhoneDateODBC = '2018-04-09'

I have investigated and found that "CallbackComment" contains the special character single quotes " ' " for one result and due to this i got this error.

In this field data is enter by customer. so we cannot restrict them like Do Not use single quotes.

sql insert from cache

I am tasked with using CACHE to insert data retrieved from a CACHE data base and insert it into an sql database. The columns in the sql table that I am trying to insert data into have names that contain underscores such as "ACCESSION_DATE" I found a utility in CACHE to connect to the sql data base and perform inserts. I have the data I need to insert. I need to pass the data into the sql utility referencing the column names.

I tried using indirection to set the data into underscored variables, but that isn't allowed in cache object script.

Recently I was asked by a customer with this question. In MS SQL Server, there is a function called host_name() that will return the work station name.

Here is how I would do it in Caché :

With default SQL schema name, in my case SQLUser in SQL (which is equivalent as User in Caché class definition), I have a class called User.dummy, I added a classmethod called hostname and expose it as SQL function host_name:

SQLCODE Error -400

I have a code block in a BPL. I have the below SQL and code. All variables have been declared and set. When I run the SQL, if there are no values returned, I get 100 for the value of SQLCODE when I perform the FETCH, which is correct. If values are returned, I get a -400 error when I perform the first FETCH. I've investigated, but cannot find the reason for a -400 error. Hoping someone out here understands this and knows what's wrong.

SQL or Cache Function?

Hi -

I'm creating a custom report in Health Insight via SQL and one of the requirements says that I must include patients who are >= 13 years old (which is easy) but I also need to include patients who WILL be 13 years old as of December 31st of current year that the report is ran in.

I see that there is an Age column and an AgeInMonths column in HSAA.Patient. and of course a DOB column. I'm wondering if it is possible to do this purely using SQL (and SQL functions) or if I will have to incorporate a COS function to achieve this requirement.

Any suggestions?

Hi All,

I use SQL function JSON_OBJECT to get data as a JSON object.

However, sometimes I get error with function JSON_OBJECT when values contain [, ], { or }.


[SQLCODE: <-400>:<Fatal error occurred>]

Unexpected error occurred in JSON_OBJECT() function execution of <JSON_OBJECT>.%FromJSON().Parsing error

For example,

Query: SELECT JSON_OBJECT('idSQL':id, 'content':content) FROM DocBook.block
