Return to Enoch
Now, I come out of my soap box and continue my story.
As Enoch has become better and better, the rename plan has been put on our agenda, and "Gentoo Linux" was born. Then, we are working towards Gentoo Linux 1.0. At about this time, I decided to upgrade my celon 300 M (overclock to micron M and very st

Here's what I learned about Oracle stored procedures, and here's a simple way to share with you the example of using JDBC to invoke stored procedures:Nonsense is not verbose, now directly on the machine code.First, I used the EMP Employee Information table from the default Scott database in Oracle as an example:If your Oracle does not have an EMP default employee table, you need to create an EMP table similar to the following.In PL/SQL, you need to write the following code that calls the stored
Label:In the initial SQL Server performance issue (1/4), we learned how to quickly check the number of tasks that are running on the server instance and the number of IO waits. This is a lightweight script that does not put any pressure on the server, even if the server is under high load and can get the results normally. The 2nd step in problem detection is to get a session that waits on any resource. The following script will help us get this information. This query requires a pre-established
. Virtual columns provide you with the flexibility to add columns that convey business awareness without increasing complexity or performance impact.
Follow these steps to create a table:

Overview:When we get to pass multiple arguments, we usually get a string of characters passed in the text format.such as:' 3115,6904,3226,3119,1173 '; But such a format is only a string when SQL is parsed, not multiple field parameters. This time we need to use the specified function to parse them.
