, and the port is dynamically assigned when the service restarts/starts, in order to access the port and start the TCP session. The client sends a request to SQL Server browser to listen on UDP 1434port. In addition, the client sends a broadcast request to the network to search for a SQL Server instance that is available, and SQL Server Browser is responsible for responding to this request, assuming there is only one instance. SQL Server Browser is not necessary, and the default installation is

We know that a function f can obtain a random number ranging from 1 to 5 with equal probability. How can we obtain a random number ranging from 1 to 7 with equal probability? Int rand7 (){Int;While (A = rand5 () * 5 + rand5 ()> 26 );Return (A-3)/3;} AlgorithmThe idea is:1. Use rand5 () * 5 + rand5 () to generate 6

Random Number problem-it is known that there is a Random7 () function, returns a random natural number from 1 to 7, so that the Random7 () is used to construct a random 1 ~ Random10 ~ 10. random7random10 Math. random () randomly generates the float number between (0, 1), and Random7 randomly generates an integer betwe

Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value. Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays 1. Define the selection position arra

Suppose rand5 can generate 1 ~ randomly ~ Use rand5 to generate rand7 () 1 ~ 7 (Equal Probability) 1. use rand5 to obtain rand2 (). When the number generated by rand5 is greater than 2, It loops until it generates 1 or 2 and the probability of generating

One-to-many association relationshipCorrelation characteristics: 1 of the party has n the one side of the collection attribute, N of the party does not have 1 of the side of the referenceFor example, if the customer has a one-to-many association with order, the customer has an order collection attribute, and the order does not have a reference to the customer. This allows the customer to retrieve all of the
