Understanding Oracle Stored Procedures and Informatica Interactions Introduction Oracle stored procedures are a powerful tool for encapsulating complex logic within the database, allowing for efficient execution of multiple tasks with a single call. However, when integrating these stored procedures with external applications like Informatica, unexpected errors can arise due to various reasons. In this article, we’ll delve into one such scenario where an Oracle stored procedure appears to work fine when executed directly in the database, but fails when called from Informatica.

Checking the Existence of Input Arguments in R Functions In R programming, functions are a fundamental building block for creating reusable code. One common task when working with functions is to check if certain input arguments exist or are present. This can be achieved using various methods, including the use of special R objects and built-in functions like exists() or missing(). However, in this article, we will explore a different approach that doesn’t involve these methods.

The Challenge of Customizing Theorem Numbering with Bookdown Bookdown is a popular R Markdown extension that allows users to convert R Markdown files into HTML documents and PDF books. One of its key features is the ability to create theorem environments, which are useful for presenting mathematical proofs and results in a structured format. However, when it comes to customizing the numbering of these theorems, Bookdown’s default behavior can be restrictive.
