It can be done with the help of SELECT … INTO OUTFILE statement. We are illustrating it with the help of the following example − Example Suppose we are having following data from table ‘Student_info’: mysql> Select * from Student_info; +------+---------+------------+------------+ | id | Name | Address | Subject | +------+---------+------------+------------+ | 101 | YashPal | Amritsar | History | | 105 | Gaurav | Chandigarh | Literature | | 125 | Raman | Shimla ...

A character class followed by operators like '?', '*' or '+' are called repeating character classes.If you repeat a character class by using the '?', '*' or '+' operators, you will repeat the entire character class, and not just the character that it matched. The regex '[0-9]+' can match '579' as well as '333'. If you want to repeat the matched character, rather than the class, you will need to use backreferences. '([0- 9])\1+' will match '333' but not “579”. When applied to the string “922226”, it will match '2222' in the middle of this string. If you do not ... Read More
List and Tuple are called as sequence data types of Python. Objects of both types are comma separated collection of items not necessarily of same type. However, main difference between list and tuple is that list object is mutable whereas tuple object is immutable. Immutable object can not be modified once it is created in memory. Hence it is not possible to add, modify or remove item from tuple object. On the other hand these operations can be performed on a list.
To allow users who work in the SAP HANA studio to connect efficiently to multiple SAP HANA systems, you can manage a list of all systems in a centrally-accessible archive. Users can then simply link to this archive.
You ByteArrayOutputStream to write byte arrays and get the result using its toByteArray() method.import java.io.ByteArrayOutputStream; import java.io.IOException; public class Tester { public static void main(String[] args) throws IOException { byte[] a = { 1,2,3}; byte[] b = { 4,5,6}; ByteArrayOutputStream baos = new ByteArrayOutputStream(); baos.write(a); baos.write(b); byte[] c = baos.toByteArray(); for(int i=0; i< c.length ; i++){ System.out.print(c[i] +" "); } } }Output1 2 3 4 5 6
When you use export option from main menu, it also exports the list of systems and their properties (name, description, host name, instance, and so on) is exported as an XML file to the specified location.
If we run simple scripts like hello.py, its output is written on the STDOUT file, i.e., screen. There is one important and extra feature available which is the first line to be printed Content-type:text/html\r\r. This line is sent back to the browser and it specifies the content type to be displayed on the browser screen.We can write advanced CGI programs using Python. This script can interact with any other external system and even exchange information with RDBMS.
Consider a situation, when we have two persons with the same name, Piyush, in the same class. Whenever we need to differentiate them definitely we would have to use some additional information along with their name, like either the area, if they live in a different area or their mother’s or father’s name, etc.The same situation can arise in your C++ applications. For example, you might be writing some code that has a function called xyz() and there is another library available which is also having same function xyz(). Now the compiler has no way of knowing which version of ... Read More
No, you cannot create a dialog box with “yes” or “no”.
