According to the order list, the HP rx2660 minicomputers in various cities are configured with 4 146 gb sas 10 k 2.5 inch hard disks. When the operating system is installed, two disks are automatically made into RAID 1, the principle is to prioritize hard disks with a large slot number (from left to right, such as 1, 2, 3, 4, 5, 6, 7, and 8 ). Check whether the host's built-in hard drive has been made into RAID 1: From the above output information,

Someone in the Forum asked if the SQL Server account can be case-sensitive. In fact, it is okay, but there are prerequisites. Many people think that only passwords of SQL Server are case-sensitive, while SQL login accounts are case-insensitive. The default SQL Server login account is case insensitive, but if you installIf the server sorting rule is case-sensitive, the login account of SQL Server will also be case-sensitive (for SA accounts, you can create SA, SA, and SA ). For example, my

OracleThe decode function in the database is one of the common functions of Oracle PL/SQL. What is its purpose? Next we will introduce this process and how to use it.SAS macroTo implement the decode function in the Oracle database. First, let's construct an example. If we want to add a salary to a staff member of zhixing, the standard is: the salary is less than 8000 RMB plus 20%; the salary is more than 8000 RMB plus 15%, usually, select the salary field value in the record first? Select salary

If is a general expression, for example, where X is missing; 3: Where can only be selected from the existing SAS data set. If statements can also be selected from observations generated by input statements.
