(5)QlikView中的RowNo()函数
函数介绍 RowNo()返回当前行的行号,在QlikView加载后的数据表中。第一行的值是1。 使用注意:此函数没有参数,但是括号不能省略。 适用范围,可以用于Load脚本,也可以用于Chart的表达式。 实例 脚本例子: SET ThousandSep=,;SET DecimalSep=.;SET MoneyTh
函数介绍
RowNo()返回当前行的行号,在QlikView加载后的数据表中。第一行的值是1。
使用注意:此函数没有参数,但是括号不能省略。
适用范围,可以用于Load脚本,也可以用于Chart的表达式。
实例
脚本例子:
SET ThousandSep=','; SET DecimalSep='.'; SET MoneyThousandSep=','; SET MoneyDecimalSep='.'; SET MoneyFormat='$#,##0.00;($#,##0.00)'; SET TimeFormat='h:mm:ss TT'; SET DateFormat='M/D/YYYY'; SET TimestampFormat='M/D/YYYY h:mm:ss[.fff] TT'; SET MonthNames='Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec'; SET DayNames='Mon;Tue;Wed;Thu;Fri;Sat;Sun'; BlogCount: LOAD*, RowNo() FROM C:\Users\zhaob001\Desktop\test.xlsx (ooxml, embedded labels);
然后加载结果,加载后的效果如下图:
Chart实例
我们在实例上增加一个表盘项来显示当前选择项所在的行数。
在表盘的表达式中写入
然后就会有如下所示:
当前行数6和第一幅图中的数据去对比就能看出来显示的行数是正确的了。
注:当用于表达式时要特别注意当前行所对应的table,如果对应错了就不会出现预期的效果了。以后再讲特殊的情况。
总结
本文总结了一下RowNo()函数的用法和功能。脚本直接在文章能发现,具体数据源可以去这里下载:数据源xls

Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.

In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

The key to writing efficient and maintainable Java functions is: keep it simple. Use meaningful naming. Handle special situations. Use appropriate visibility.

1. The SUM function is used to sum the numbers in a column or a group of cells, for example: =SUM(A1:J10). 2. The AVERAGE function is used to calculate the average of the numbers in a column or a group of cells, for example: =AVERAGE(A1:A10). 3. COUNT function, used to count the number of numbers or text in a column or a group of cells, for example: =COUNT(A1:A10) 4. IF function, used to make logical judgments based on specified conditions and return the corresponding result.

The advantages of default parameters in C++ functions include simplifying calls, enhancing readability, and avoiding errors. The disadvantages are limited flexibility and naming restrictions. Advantages of variadic parameters include unlimited flexibility and dynamic binding. Disadvantages include greater complexity, implicit type conversions, and difficulty in debugging.

The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.

The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.

2024 is the first year of AI mobile phones. More and more mobile phones integrate multiple AI functions. Empowered by AI smart technology, our mobile phones can be used more efficiently and conveniently. Recently, the Galaxy S24 series released at the beginning of the year has once again improved its generative AI experience. Let’s take a look at the detailed function introduction below. 1. Generative AI deeply empowers Samsung Galaxy S24 series, which is empowered by Galaxy AI and brings many intelligent applications. These functions are deeply integrated with Samsung One UI6.1, allowing users to have a convenient intelligent experience at any time, significantly improving the performance of mobile phones. Efficiency and convenience of use. The instant search function pioneered by the Galaxy S24 series is one of the highlights. Users only need to press and hold
