## esProc Getting Started: Constants

In esProc computing, we use constants frequently or sometimes store the data in the cellset directly. In this article, let’s learn the usage of constants in the esProc. 1. Directly using constant in the expressions Constants can be directly used in the esProc expressions:   A 1 =64*32 2 =round(1.45*5.5) 3...

## Getting Started: Basic Usage of JDBC

esProc can be embedded into Java program. So the latter can call the cellset program written in esProc using a way of connection such as JDBC. The method of calling the esProc program is the same as that of calling the stored procedure. The following is a brief introduction to esProc JDBC.  1. Description of the j...

## esProc Program: Sequence and Table Sequence (II)

3. A record sequence is the reference of table sequence records  Obviously, if each computation on a table sequence is to produce a new table sequence, a great deal of the memory will be used. For instance, a table sequence, Order_Books, has 50,000 records, and 30,000 records are obtained by query. If new table se...

## esProc Program: Sequence and Table Sequence(I)

Sequence, table sequence and record sequence are commonest data types of esProc. This article tries to expound their respective characteristics as well as relations between them. 1. A sequence is an ordered generic set 1.1  Collectivity A sequence consists of multiple data, which is called members of the sequ...

## esProc Getting Started: Basic Data Types

1. Data types in esProc In esProc, the following basic data types are available: Integer Any integer between -231 and 231-1, i.e. the value range is -2147483648~2147483647. The type conversion function int() can be used to convert other types of data into integer. Long integer -263~263-1, which is a value range bigger ...

## esProc Getting Started :Cell Editing

1. Cell Copy and Paste In esProc, you can press Ctrl+C and Ctrl+V to copy data or an expression in some cell and paste it on the target done. But unlike EXCEL, the copy and paste operations on the cell will not perform the adjust-paste on the expression automatically. If you need to adjust the cell quoted by the expre...

## esProc Getting Started: Types of Cells

In esProc, cells are automatically classified into different types according to their values or the expressions they contain. In a cellset, each type of cell has its own appearance, which highlights the code in the cells. 1.Types of cells 1.1    Constant cell A cell in which the cell string can be interpreted as the co...
