garbage collection mechanism does not immediately reclaim the IDbCommand temporary objects, and the parameter set of object bindings also exists, just as a DropDownList adds item. This causes two idataparametercollection to point to the same object at the time of the next loop execution, and there is a problem.Solution One: Regenerate the object at each iteration, but this produces a lot of garbage variables, which is undesirable.Solution two: Empty the Parameters collection of command commands

In a Web application developed with PHP, PHP file Containment is a common vulnerability. The use of PHP files containing vulnerability intrusion site is also the mainstream of a means of attack.

Full-text index-CONTAINS syntax We usually use CONTAINS in the Where clause, like this: Select * FROM table_name Where CONTAINS (fullText_column, 'search CONTENTS '). Let's take an example to learn about it. Suppose there is a table students, where the address is a full text retrieval column.1. query student addresses in BeijingSelect student_id, student_nameFR

Since then, I have done a lot of research on these methods and have used them in many occasions. In many tasks, they prove to be very useful (especially concerning the abstract DOM selector of structures ).1. DOMElement. contains (DOMNode)This method was first used in IE to determine whether the DOM Node is contained in another DOM Element.This method is useful when you try to optimize CSS selector traversal (for example, "# id1 # id2. You can get the

there are many useful methods for IE, which were later copied by other browsers, such as the contains method. If element a contains Element B, true is returned; otherwise, false is returned. The only thing that does not support this method is the opposite of IE Firefox. RunCode However, Firefox supports the comparedocumentposition () method, which is developed by W3C and supported by standard browser
