The SQL language has two components:
DML (data manipulation language): They are SELECT, UPDATE, INSERT, and DELETE, just like their names. These four commands are used to operate the data in the database.
DDL (data definition language): DDL is

Now we will introduce the test main program: Test. Exp.
To facilitate the addition of new test projects, the main program uses a flexible mechanism, which calls the corresponding sub-test programs through the source command as needed. In this way,

impossible, since it is not possible to have multiple threads operating on the same shared variable at the same time. We can express this explicitly as a rule:
at any time, two threads operate concurrently on a shared variable, one of these operations performs a write action, and all threads must use atomic operations.
If you violate this rule and one of the threads uses non-atomic operations, you will fall into a situation called data contention in the C++11 standard (not to be

The main idea of implementing a double-layer header in the gridview is to rewrite the header using the rowcreated method of the gridview.
The implementation is as follows:

Server I told a story of the background is this, in a certain POS project using SQL SERVER 2000 to do the foreground database, IBM's DB2 do background database. The environment for the foreground database is such that the operating system is Windows Server (USERS), and the database is SQL Server (E) +sp3,application is a POS system (a real-time trading system). Hardware configuration is: P4 xron 2.4g*2,36g hdd*5 RAID5, 1G memory,hp tape drive, the database capacity is generally kept at 5G or so.
