Qlikview Data Modeling --- Concatenation, qlikviewThis Blog introduces how to avoid loops and synthetic keys through Concatenation (Concatenation) fact tables:The Modeling in Qlikview is usually very simple. Generally, we only need to rename the names of some sub-segments to prevent or establish automatic association between tables.But sometimes we can't solve the problem by simply renaming it. For example,

Problem Background: The company spent more than N to ask for a solution made by qlikview consultant, which did not involve reload, so that the entire data model needs to be refreshed every time the data is refreshed, in my previous discussions with my colleagues in the Department, I also vowed that qlikview could only be like this, you cannot find a method to refresh the new data to the data model without l

Label: join load autonumberhash265 keylink table qlikviewIn the future, we will learn how to create a Key or Link Table in QlikView to prevent fact tables loops and qlikview from automatically generating synthetic keys. When two fact tables share the same key set, concatenation should be the preferred solution to avoid qlikview automatically creating a synthetic

In the QlikView, you can select certain configurations to easily convert chart types. You can select a chart to view details such as a bar chart, bar chart, or vertical chart. After selecting the options shown in FastTypeChange, A FastChange option is added in the upper-right corner of the chart to the following: In the QlikView, you can select certain configurations to easily convert chart types.

QlikView connects IBM DB2 via ODBCPART1: Creating an ODBC-driven connection for IBMDB2First go to the control Panel to findControl Tools,--> Choose an ODBC data source based on the version of your system,Because the IBM DB2 database needs to be connected via an ODBC data source, you need to go to the IBM website to download the driver driver that is right for you based on the number of bits in your system.Because my system is 64 bits, I am here to sha

The Qlikview chart can be easily configured by examining some of the transformations that can be made to the chart type, allowing the user to select the graph above as a bar or histogram or a vertical chart detail data.After you select the option as you see in the Fast Type change. There is a fast change option in the upper-right corner of the chart. It becomes the following:Since the preferred icon in the lower right corner of the first image is chec

Implement RowNumber () Over (Partition by) and qlikviewrownumber in SQL Server in QlikView This is often the case when field A has many duplicate values, but the values in field B are unique After grouping by field A. Therefore, SELECT, when field B is used, you do not know which value in field B is used. Therefore, when field A is repeated, you want to obtain the value of field B, the data must be based on the row corresponding to the maximum and min

Often there is a requirement that when a field has a lot of duplicate values, but the values in the B field are unique after grouping by a field, so select a, B fields do not know which value in the B field, so when the A field repeats, you want to take the value of the B field, The row of data that corresponds to the maximum minimum value in the C field.SQL Server can be implemented as follows, Row_number () over (Partition by A Order by C) ID, and then take id=1.In

difference set (XOR operator) operator. This binary operation returns a collection that is contained in two collection operands, but does not consist of records that are common to them.Operator precedence is: 1) Unary negative operator (complement), 2) intersection and symmetric difference set operator, 3) and exclude operator. Within the same group, the expression is judged from left to right. The non-priority order can be determined by the standard brackets, which may be necessary because the

There is a "Show Systemfields" option in User Preferences, Settings . If you check this option, you can select the System field when you create a new List Box . Or not. So how do you define system fields?As shown in the following code:After hideprefix= "_" is defined, all fields whose names are prefixed with "_" will be treated as system fields. As shown, you will not be able to see the _test4 field when you create a new List Box .After checking "Show System Fields" in User Preferences , create

The customer often asks for this. When the user selects a time, the data of the year before the selected time is displayed in the chart. The following is my method. If there is any improper method, please advise: Data preparation is as follows: Salesdata: loadnum (ID) as ID, date (date) as date, month, num (year) as year, num (sales) as salesinline [ID, date, month, year, sales1, 2012-1-1 1, 2012-1, 2012,202,201 2-1-1 1, 2012-2, 2012,213,201 2-1-1, 2012-3, 2012,234,201 3-1-1, 2013-1, 2013,34

the second parameter in the first year of October 1. If yes, the formula returns-1; otherwise, it is 0. In the example above, October 1 is the first day of the new year. Because the third parameter is 0, the first parameter is directly compared with the second parameter, indicates whether the value in the date field is the same as today's one year starting from January 1, October 1. For example, 2013-11-1 is, And 2013-09-31 is not. Inyeartodate (date, today (),-1, 10) indicates that the field
