We have to admit the fact that in the course of Java Learning we can do some development if we have mastered a variety of programming methods and tools, which is why some training institutions dare to tell you that you can master a language in a few months. But with the development of time, we always feel that this kind of people if not to promote themselves, and finally will only be a yard farm. Technology will change rapidly, at any time in the development of the replacement, but these decades

Merge data 3 ----------- conditional split and slowly changing Dimension components Search for Excel and databases using productnumber. When the data is in Excel but not in the database, it is added; when all data is in Excel, it is updated; if there is data in the database
The day before yesterday, Insus. NET implemented "dynamically merge columns of the GridView data row DataRow". Today, I will play with the Repeater control, which is also used to dynamically merge certain column spaces.The Repeater control has the same high degree of integration as the GridView control. The more free and loose the control, the worse the control.O
Last time, we did not integrate the data in Excel with the data in the database. If there is an update, there is no insert. This time we mainly introduce several methods to achieve this:1. Use Lookup2. Use Execute SQL task to call the Stored Procedure3. Use the script component script to implement4. Use the merge Statement (SQL Server 2008)5. Use the

decided to use stored procedures to achieve, previously used if exists to match. Later found that the efficiency is not high, relatively slow, after the subsequent improvement of the introduction of Oracle merge into to achieve;The specific case code (most of the fields removed) is as follows: 1. Compare the data in the temporary table l_table with the formal table z_table, if the values of each field are

There are two tables, each of which contains about data table fields: idpidname .... table 2 field: idpidage .... now we want to merge the table data with idpidnameage... how can we achieve better results? There are two tables, each of which has approximately data records? Table field: Id pid name .... Table 2 fields:
The procedure is as follows: ① Create a configuration instance, which is responsible for managing the template loading path of freemarker and generating template instances. ② Use the configuration instance to generate a template instance and specify the template file to be used. ③ Fill the data model. The data model is a map object. ④ Call the process method of the template instance to complete the

The previous version of the dynamic merge Repeater control data column http://www.cnblogs.com/insus/p/3240848.html.Today, Insus. NET re-demonstrated it. Why? Because two points are required to be rewritten. First, the column code generated by cs is redundant. Second, exceptions may occur during merging. What should I do? In this example, the data of the columns t
