Use scripts to implement dynamic data sources for reports and dynamic data sources for reports Some reports in the report system often need to connect different

operations, it is very easy to select part of the data (odd day) from a set (ALL dates. Unlike computing in a general report tool, the set compute does not have any display attribute during data computing, so it is more efficient. At the same time, because the report end no longer contains a large number of hidden cells, the report efficiency is further improved. In addition, for scripts with simple code,

The last time I made the method of using oledb to connect to the database directly in the rpt file, but it was not very flexible. This time I used SQL statements to directly generate dataset as the report data source (that is, the push mode ), in this way, you can accept the parameter. Of course, I have not studied the function of setting parameters in reports in detail. I. Table association is not used

Most projects require only one transaction manager. However, some projects are best used with multiple transaction managers to improve efficiency, or to have multiple disparate and disparate data sources. Smart Spring's transactional management has taken this into account, first defining

In the previous section, we talked about multiple data scenarios:1. Different data sources (different database vendors, different business scope, different business data)2. Unlike SQL mapper files,3. MyBatis + Data dialect differe

The report shows the following results: As you can see, using a collector script can quickly accomplish this type of scenario with multiple judgments. Moreover, the external set-up script has a visual editing and debugging environment, and the edited script can be reused (called by other reports or
