Hi Tom,

We are in process of creating a Java user defined Function and in order to achieve that  we have deployed the JAR File in the database and

 creating a function/procedure on the top of it  using the below two approaches :

 

I have a java udf that basically just does a bunch of shows on each and every procedure and macro and then inserts those into a table. The jar is installed and my definition for the procedure is below. The problem i'm getting is i keep getting the error:

Customers are currently leveraging Teradata's features such as User Defined Functions (UDFs) and External Stored Procedures (XSPs) to develop complex applications.

The aim of this set articles is to show the user how to use the Eclipse IDE to debug in a single-node, controlled, non-production environment:

  • Java or C/C++ User Defined Functions (UDFs)
  • Java or C/C++ External Stored Procedures (XSPs)

The audience for this set of articles ranges from Teradata associates within the R&D and Professional Services organizations to  Teradata Customer and Partner developers who want to debug a UDF/XSP running on their  DBS VM before installing it on a production system.

SQL provides a set of useful functions, but they might not satisfy all of the particular requirements you have to process your data.

User-defined functions (UDFs) allow you to extend SQL by writing your own functions in the Java programming languages, installing them on the database, and then using them like standard SQL functions.

An integrated development environment is crucial to software developers for editing, building and debugging their program all within one environment. Therefore, setting up the right development environment is an important first task.

 

Hi I want to overload the java UDFs but I am getting the "Function already exists"error even function parameters are different for both functions.

 

Here is how my java UDF code looks like

Hi,

i was trying to write a simple udf with java with an input argumentn of type string which sometimes also expect null inputs. Whenever I got a null  input it gives the error even I tried it with return null on null input option. Can someone please suggest me that how to handle it. Thanks

hello

As most of you might agree, managing our collections of digitial pictures is becoming quite a challenge.  The number of photos continues to increase and now includes pictures from cameras as well as multiple mobile devices.  And to add to my troubles, I find that I have duplicate copies in different folders and on different computers.  Getting this organized is becoming a high priority.  Sure there are management solutions already available, but hey, we're tech people and it's more fun to try to build our own!  With the free Teradata Express database and some java coding, we have the right tools to get started.

Hello,

I'm using two different types of Java :

C:\Program Files\Teradata\jvm\jre5_32\
C:\Program Files\Java\jre6

which I can switch in : Teradata Service Manager -> Update TDJRE ( so Register value on JRE is changed )

I'm also using plugin for eclipse and Teradata Express v13.00.00.12 / Windows 32 bit

I'm able to:

- connect to database,
- create user
- create schema
- in teradata command pompt I can see path to java.
- I have all grants to create JUDFs ( inc. ALTR EXTERNAL PROCEDURE )
- I have SQLJ schema with INSTALL procedure
- Java is set to 1.5

Teradata 13.0 supports a Java User Defined Function (JUDF) capability, which returns an Aggregate. Aggregate functions produce summary results. In the last Article, you were shown how simple it is to create a Table JUDF using Teradata tools. Now, in this article you will be shown how easy it is to create an Aggregate JUDF using the Teradata Plug-in from Eclipse. The Teradata JUDF Wizard and Editor simplify the process of creating, installing and editing an Aggregate JUDF.

Teradata 13.0 supports Table Java User Defined Functions (JUDF). A Table Java User Defined Function returns a table of data a row at a time in a loop to the caller of the function. This article will show you how to use the Teradata Plug-in for Eclipse to quickly create a Table Java User Defined Function.

A Teradata Database Java User Defined Function (JUDF) is a program that operates on data stored in relational tables. UDFs allow users to add their own extensions to the Teradata SQL language. JUDFs are implemented as external functions. This means the source is compiled externally to the DBS and kept in Java Archive (JAR) files. These JAR files are installed into the database using stored procedures in the SQLJ database. Once a JAR file is installed a JUDF can be defined to use a Java class and method within the JAR file. The JUDF is executed via a protected mode server separate from the database process. Parameters passed from the DBS are converted to their Java form and the Java return type from the JUDF  is converted back to its DBS form.
