Examples of esProc’s Assisting in Dynamic-Column-SQL Computations

The SQL implemented by database vendors can be used to write dynamic statements. But since it’s inconvenient to perform set operations and order-related computations in SQL, usually you must resort to the high-level languages to handle the dynamic-column computations, which leads to a cumbersome process of doing these computations. As esProc (free edition is available) […]

The Standard esProc Method of Assisting SQL-style Transposition

In many cases SQL is used to implement a transposition algorithm, such as static/dynamic transposition, natural/inverse transposition, single-/multi-group data transposition, transposition after data alignment/complementing and transposition with/without computed columns. There are different SQL implementations for different scenarios. Some need the pivot function, some require group+case when only, some use the union, and others depend on […]

How esProc Assist Reporting Tools with Inter-row Calculations

Not all reporting tools support inter-row calculations directly. When they don’t, you need to write scripts to implement them, which is really a big hassle, even bigger when multilayer data grouping is involved. esProc can deal with this situation thanks to its support for order-related calculations. An esProc script can be identified as a database […]

Perform File Comparisons using esProc

You can handle simple file comparisons with the console command, Java, python and perl. But all of them are not good at performing set operations and structured computations. This will result in complicated code for multi-threaded processing and cumbersome process in comparing multiple fields, big files and the files with different structures. As esProc (free […]

How esProc Implements Text Processing

Encapsulated lots of functions for handling structured file computing, esProc can import text files with complex formats, carry out cursor-style processing with big files and simplify multithreaded parallel processing. Usually there are three modes in which esProc can be applied: a standalone mode, the execution from command line and Java integration, as shown below: The […]

Diverse Scenarios of esProc’s Assisting in Report Development

There are many knotty problems around report development. These include complex layout, which is difficult to build with a reporting tool alone; complex data sources requiring dynamic access and involving different types of databases or non-database data; as well as the handling of order-related computation, subsets of grouped data, fixed grouping, string splitting and concatenation, […]

esCalc Structure: The Smart Copying of Formulas

If you enter a formula into a cell in an esCalc spreadsheet, it will automatically appear in each of the cell’s homo-cells and intelligently adapt itself to the new settlement. If you set one of the cell’s properties through a formula, all its homo-cells will receive the property setting simultaneously. Here we’ll discuss the esCalc […]

How esProc Assists Java in Handling JSON Data

Java can handle simple parsing of semi-structured JSON data, but has difficulty in handling the in-depth processing. esProc, which supports set operations, order-related operations and dynamic script execution, can help reduce the difficulty. A Java application will execute an esProc script in the same way as it executes a database stored procedure, pass parameters to […]

esCalc Structure: Homologous Relationship

Some data in a spreadsheet contains the same type of topics. Through the structural and hierarchical way, esCalc creates homologous rows and cells – which are called homo-rows and homo-cells – containing data of the same information type. Here’s the explanation of what this homologous relationship is and the advantage of its design. 1. Homo-rows […]

Examples of esProc’s Handling of Unusual Report Layouts

It is difficult to produce unusual report layouts automatically with functionalities provided by reporting tools. But if we can prepare data sources in an appropriate way, the difficulty of building such a report will be significantly reduced. To do that, we can use esProc (its free edition is available). It not only supports set operations, […]

esCalc Structure: Functions

esCalc stores data in hierarchical, structured spreadsheet, which enables the use of structure-related functions in performing data analysis and aggregation. Here let’s talk about these functions and their basic usages. 1. The sequence of cell values Through esCalc Basics: Sequences, you know that [a:b] can be used in a formula to calculate a sequence composed […]

How esProc Assists Java to Query Big Text Files

Sometimes you need to query a big text file, instead of the database. In those cases, you need to retrieve the file in a stream style to perform the query algorithm, in which parallel processing is needed to improve the computing performance. As Java lacks the class library for doing these, you have to use […]

esCalc Structure: The Hierarchy of Rows

Different from other spreadsheet applications, esCalc spreadsheet isn’t designed for holding a normal two-dimensional table, but for holding data in a hierarchical way. Here you’ll see in what type of structure the data is stored in esCalc and the hierarchical relationships between rows. 1 .Row number, slave row number and level A simple state population […]

How to Use esProc to Handle JSON Data for Report Development

With class library for merely simple parsing jobs, Java and reporting tools have difficulty in handling in-depth processing of semi-structured JSON data. esProc can help reduce the difficulty. A reporting tool will execute an esProc script in the same way as it executes a database stored procedure, pass parameters to the script and get the […]

How to Use esProc to Assist Reporting Tools

esProc has lots of functions for processing structured and semi-structured data, as well as supports parsing expressions dynamically and using heterogeneous data sources. A reporting tool can pass in parameters, execute an esProc script the same way as it executes a database stored procedure and gets the result set through JDBC.  Below is the structure […]
