Oracle linesize command, oraclelinesizeYou can use the linesize command to set the number of characters that a row can accommodate. The default value is 80. If the linesize value is small,A row of data in the table may be displayed in multiple rows on the screen. If the value of linesize is larger, one row of data can be displayed inThe screen is displayed in one line.The linesize command syntax is as follows:Set linesize nWhere, n indicates that a row of data on the screen can be accommodated.N
Oracle uses the pagesize command and oraclepagesize commandYou can use the pagesize command to set the size of each page to control the data volume displayed on each page. Syntax format of the pagesize commandAs follows:Set pagesize nHere, parameter n represents a positive integer of the size of each page. The maximum value can be 50000, and the default value is 14. The page is not only output data.It consists of all the output results from SQL * plus to the screen, including the title and blank

Ii. Aggregate functions and group queries
1. Aggregate functions
Common Aggregate functions include AVG (all/distinct field name), count (all/distinct field name), max (field name), min (field name), and sum (field name)
2. query groupsGroup by statement
The group by statement is used in combination with the aggregate function to group result sets based on one or more columns.SQL group by syntax
SELECT column_name, aggregate_function
In the data warehouse, null values are used to indicate conditions in which the actual values are unknown or ambiguous. In a table, if a column in a row does not have a value, it is called null ). For any data-type column, you only need to use the non-null (not null) or primary key to finish the integer restriction, can be empty. In practice, if a null value is stored, it will become unnecessary.

F401 although the appearance is small, but the function is not weak, the body is equipped with Super ccd iii, the actual CCD painting 2.1 million, recording painting up to 4 million (2304x1728 pixels ), as Super ccd iii significantly improves noise, the effective ISO sensitivity is increased to 1600 degrees. by increasing the concentration rate of CCD, photography with a higher sensitivity can be performed than before. Its optical system uses
in the world's GHz engineering medical (ISM) frequency band and uses the Frequency Hopping (FHSS) technology ). The frequency hopping rate is 1600 times per second. A maximum of 79 1 MHz bandwidth channels can be obtained at a GHz center frequency. The Bluetooth device uses gfsk modulation. The transmission rate is 1 Mb/s. The actual effective rate is up to kb/s, and the transmission distance is 10 m. Voice Transmission uses Continuous Variable Slope
DVI interface appearance of current graphics card DVI interface is almost all using DVI-I, only need to connect a DVI-I to D-SUB adapter, you can connect the D-SUB plug. DVI-I to D-SUB adapter but in the market, we can often see that the DVI line has 18 + 4pin and 24 + 4pin these two specifications. Some people say that 18 + 4pin is a simplified version, and the performance is not as good as 24 + 4pin. Others say that some of 24 + 4pin are ground wires, and the actual effect is the same as that
pixels, and the higher the DPI value, the finer the image, the smaller the pixel to the point that the human eye cannot tell, and the image looks different from the actual one.
This is the concept of "how many thousands of pixels" for a digital camera. For example, a camera can take up to 1600 pixels * 1200 pixels of photos, the pixel value is 1600*1200 = 1.92 million, which is about 2 million. This is a 2
