implemented and one module is debugged, it can still be solved. Haha ~ Question: Searching quickly Background Searching and sorting are part of the theory and practice of computer science. for example, binary search provides a good example of an easy-to-understand algorithm with sub-linear complexity. quicksort is an efficient [average case] comparison based sort. Kwic-indexing is an indexing method that permits efficient ''human search'' of, for example, a list of titles.The Problem Given

An example of Full-text indexing, used in Query Analyzer: Use pubs Go --Support for open database Full-text indexing Execute sp_fulltext_database ' Enable ' Go --Create a Full-text catalog Ft_titles Execute sp_fulltext_catalog ' ft_titles ', ' create ' Go --To create a full-text indexed data element for the titles table, Upkcl_titleidind is the only index established by the primary key, which can be learned by sp_help

Create roles, users, permission/* -- Example: In the database pubs, create a role r_test with all permissions for table jobs and select permissions for table titles, and then create a login Rochelle test, then, create the user account u_test for login l_test in the database pubs and add the user account u_test to the role r_test, the user obtains the same permissions as role r_test through permission inheritance, and finally uses the deny statement to

Control as follows: After you setDatasourceProperty for the childRepeaterControl, the HTML code for the twoRepeaterControls (Parent and Child) appears as follows: 3. Add the following page directive to the top of the page: 4. In the code-behind page, replace the following line in the page_load event // insert code in Step 4 of the next section here. with the following code: // create a second dataadapter for the

tempdb. In a multi-user concurrency environment, it is easy to block other processes, Therefore, I suggest using CREATE TABLE + insert into in a concurrent system, while using select into in a single statement with a large data volume. Vi. subquery usage A subquery is a SELECT query nested in select, insert, update, delete statements, or other subqueries. Subqueries can be used wherever expressions are allowed. subqueries allow flexible programming and can be used to implement some special func

. For related subqueries, it should be noted that: (1) A, not in, not EXISTS related subquery can use the left join instead of the notation. For example: Select Pub_name from publishers where pub_id not in (select pub_id from TITLES WHERE TYPE = ' business ') can be rewritten as: Select A.pub_name from Publishers A, left JOIN, TITLES B on b.type = "Business" and a.pub_id=b. pub_id WHERE b.pub_id is NULL

? First, you create a DOMDocument object$dom = new DOMDocument ();Then load the XML file$dom-> Load ("Test.xml"); Output XML fileHeader ("content-type:text/xml;charset=gb2312");echo $dom-> savexml (); Save an XML file with a return value of int (file size, in bytes)$dom-> Save ("Newfile.xml"); echo "$titles = $dom-> getElementsByTagName ("title");foreach ($titles as $node) {echo $node-> textcontent. "Th

can be used to implement special functions. But in performance, often an inappropriate subquery usage can create a performance bottleneck. If a subquery's condition uses a field of its outer table, this seed query is called a correlated subquery.Correlated subqueries can be introduced with in, not in, EXISTS, not EXISTS. For related subqueries, it should be noted that:(1) The related subquery for not in, not exists can use the left join instead of the notation. Like what:Select Pub_name from Pu
