the product table, and 31 milliseconds for each CPU. In addition, I reviewed the execution plan for SQL Server that was created for these two queries. I found that SQL Server produced the same execution plan for both cases. So, in my case, using a subquery or a connection query produces equivalent performance, as Microsoft has recorded. Summary A subquery is a SELECT statement that embeds another Transact-SQL statement. Subqueries can run independently of external queries, and are sometimes r

The second line, if the major version number () of QT is QT_MAJOR_VERSION greater than 4, which is QT 5, you need to add widgets (because in QT 5, all components are defined in the Widgets module). TARGET is the name of the generated program. The template is used to generate makefile templates, such as the app is compiled into an executable program, and Lib is compile

In C/C + +, ASCII is supported, but GB2312 is compatible with ASCII in Chinese character coding, so the GB2312 encoding of Chinese characters can be obtainedThe GB2312 is two bytes, the first byte is high eight bits, the second byte is low eight bits, such as the following program:#include #include int main (){Char a[5];strcpy (A, "ah");printf ("%xh%xh\n", (unsigned char) a[0], (unsigned char) a[1]);return 0;}A[0] is the "ah" character of the high eight-bit, a[1] is low eight bits, the program r
