Currently, page turning is usually performed on the default page of The DataGrid. Although only data on the current page is bound in this way, the dataset returned from the database is still the entire dataset, if the query returns a large data set, it will take a lot of time to flip the page, because it wastes network bandwidth and server resources (bind a page, but still returns the entire dataset ). therefore, the optimization principle for this situation is: if the default page of The DataGr

Activiti process about custom SQL query, activitisql Because I was not familiar with Activiti, I was not familiar with the table structure. Even the entity classes corresponding to those tables were not clear, and I could not implement them through the chain query provided by Activiti; in this case, you do not know how to use SQL to implement the query you want.

In the process of making a report, there is a report to query the exchange rate of the corresponding currency, and the exchange rate in another table, and the criteria for querying the exchange rate is based on the statistical date of the report (page passed in parameters), to the exchange rate table for the date of the last one months of exchange rates, if there is no previous month's exchange rate , therefore, a function that gets the exchange rate is customized, put in

Added support for CLR in SQL Server 2005, which allows us to write functions, stored procedures, triggers, and other objects for SQL Server in C # and VB. NET languages. There is not much to say about how to create these objects. There are many searches on the Internet. Here we will talk about some noteworthy issues when creating Aggregate functions. Custom
