method is as follows: first, you need to change the current table to a partition table and it is critical to find the partition field. Second, the index of this partition table is created as a local index, the global index is not needed. The reason is described later. Create a temporary non-partition table with the same structure as this one. Use alter table table_name exchange partition Partition_name with table table_name_exchange, swap the actual physical storage space segments of the data o

We will take a look at the header in the next subunit.We only use the page to directly read the header, no matter where the page components are stored. this is a good opportunity to introduce the directory settings of the template tag system. by default, the template directory layout is as follows (note that these paths are relative to our application ):The Default PhpMVC_Tags Template Directory Layout Paths (relati

bridge of _ call () method. I personally think this technique is a double-edged sword. do not over-use it. 5. callback function: The application scenarios of callback functions do not need to be described. in C/C ++, there are countless typical use cases of callback functions. Here is a simple example of how to use callback functions in PHP. See the following sample code and Key notes: Class Product { Public $ name; Public $ price; Public function _ construct ($ name, $ price ){ $ Th

, if the lock flag of the str monitor is 0, other threads will enter a waiting thread pool generated by the str monitor's flag lock. The lock flag of the str monitor is only available when the lock flag of the str monitor is changed to 1. Note: String str = ""; must be placed outside the run () method. You can also use the synchronization function to achieve the synchronization effect. Check the Code: 5.3 TestThread10.java Package com. thread; public class TestThread10 {public static void main (
