1. Located in the path: C: "Books" Learning under the text file MyData.txt, its data to open, the form is as follows:M 50 68 155F 23 60 101M 65 72 220F 35 65 133M 15 71 166The code to read into the SAS is as follows:Data demographics;InFile ' C: "Books" Learning "MyData.txt";Input Gender $ age Height Weight;RunThe symbol $ indicates that the variable gender is a one-character variable. To check that the read-in file is correct, you can view its observ

compatible with the PATA device by using a multi-purpose chipset or serial-parallel converter. Because SATA and PATA can use the same drive, you do not need to upgrade the operating system or perform other changes. 5. You do not need to set the jumper of the Master/Slave disk for Sata. The BIOS will number it in the order of 1, 2, and 3. This depends on the SATA connector to which the drive is connected (easy to install ). However, the IDE hard disk must be configured with a jumper to set the

The most recent project to do Blade server is to use HP D2600 SAS storage. Although it is very simple storage, but because the price is much lower than the P4x00 series SAN storage, it should be said that the scope of use is relatively broad. Of course, some people say this is not comparable, for large enterprises, I fully agree. But for ordinary small and medium-sized enterprises, P4X00 series is a standard SAN, the price is indeed a little expensive

1: Prevent unnecessary sortingHere are four ways to prevent sorting?? 1.1:by-group processing with an index to avoid a sortThe by statement does not use the index in the following casesThe by statement includes the descending or notsorted option or if SAS detects that the data file is physical Ly stored in sorted order on the by variablesThe pros and cons of index columns used for sortingDisadvantages:?? 1:it is generally less efficient than sequentia

Recently in doing the SAS conversion code, learned before, but the time has been forgotten, in order to easily find later, so again to review the time, the SAS study carried out a simple record. Common syntax structure of SAS The basic type of the SAS variable First: Numerical type Second: Character variable name must

What is SAS? SAS is a new generation of SCSI technology, and the popular Serial ATA (SATA)Hard DiskSimilarly, serial technology is used to achieve higher transmission speeds and improve internal space by shortening the connection lines. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the efficiency, avail

SAS hard Drive, is a serial connection to the next generation of SCSI technology, the use of serial technology to achieve higher transmission speed, and by shortening the connection line to improve the internal space. SAS is a parallel SCSI interface that develops a new interface. Improves storage system performance, availability, and scalability, and provides compatibility with SATA hard drives. Character

Disk back panel: Eclectic In the tower server where the rack server or the hard drive slot is higher, the SAS Hba/raid card is generally not connected to the hard drive directly with the SAS cable, but through the disk backplane to facilitate the hard drive Plug and unplug. Disk Backplane is also a typical internal connection application, one side of the hard drive, the other side even Hba/raid card. Drive

1:where and if the most essential differences, as well as some small differences1.1:the WHERE statement examines what was in the input page buffer and selects observations before they was loaded in the P Rogram data vector, which results in a savings in CPU operations (where to filter from buffer and then read into PDV)The subsetting IF statement loads all observations sequentially to the program data vector. If The statement finds a match and the statement are true, then the data is processed a
