when you use a loop, you provide an initial condition, such as the starting point, and a termination condition that tells the loop when to stop. the instructions within the loop are executed repeatedly until the termination condition is satisfied. what are the different types of loops? in ...

o Nesting FOR XML with sub-query syntax currently in most practical cases translates into Nested Loop join. However, there can be a combination of indices when joins and unions in AUTO and EXPLICIT modes of FOR XML are translated into more efficient MERGE or HASH joins, or MERGE unions. ...

Make decisions.When you reach a diamond symbol, understand that a decision is required. Follow the arrows leading from the decision point based on the outcome. Look for loops and subprocesses. Some workflows may loop back to previous steps or include subprocesses. Pay attention to these elements...
最后讲解了 HASH JOINS 明显感觉到讲解者的自信,在将这段的时候一直是面带微笑,其中一大段的话的意思是,NESTED LOOP 在处理两个或多表的JOIN 运算是有很大的缺陷的,经常会导致 CPU 很高效率很低,因为每次都会根据索引来分批读取数据进行处理,而HASH JOIN 将是改变这样不明智处理的改革方式,在其中一个表中对要比...
