SQL Create Table - The Coding Shala

Home >> Learn SQL >> SQL Create Table

SQL CREATE Table Statement

SQL CREATE TABLE statement is used to create new tables in the database. CREATE DATABASE statement is used to create the database. The important thing here is SQL keywords are not case sensitive means create is the same as CREATE. Below is the SQL CREATE TABLE statements and its examples are given.
SQL CREATE Table - The Coding Shala

CREATE DATABASE Syntax

The following is the statement is used to CREATE DATABASE -  
 CREATE DATABASE database_name;


SQL CREATE DATABASE Example

 CREATE DATABASE mydb;
  • This query will create a new database in SQL and name the database as mydb.

CREATE TABLE Syntax

The following CREATE TABLE statement is used to create tables in the database - 
 CREATE TABLE table_name  
        (        
         column1 datatype(size),  
         column2 datatype(size),  
         column3 datatype(size),  
         ..  
         ..  
         );



SQL CREATE TABLE Example

 CREATE TABLE Persons  
 (  
 PersonID int,  
 LastName varchar(255),  
 FirstName varchar(255),  
 Address varchar(255),  
 City varchar(255)  
 );
  • This query will create a table in the database named Persons.
  • By using the 'DESC' command we can verify if the table is created or not.
Syntax
 DESC table_name;

Example
 > desc Persons;  
       Field         Type         Null       Key       Default     Extra  
 1     PersonID      int(11)         YES          NULL       
 2     LastName     varchar(255)     YES          NULL       
 3     FirstName     varchar(255)     YES          NULL       
 4     Address         varchar(255)     YES          NULL       
 5     City             varchar(255)     YES          NULL

Java Program to Convert Binary to Decimal - The Coding Shala

Home >> Java Programs >> Convert Binary to Decimal  Hey there, welcome back to another post. In this post, we will learn how to convert Binary to Decimal in Java. Java Program to Convert Binary to Decimal You have given a binary number, convert it to a decimal number. Example:  Input: 101 Output: 5 Input: 111 Output: 7 Binary to Decimal Conversion in Java Approach We will the below formula to convert binary to decimal: decimal number = (2^0) * (rightmost digit) + (2^1) * (second rightmost digit) + ...  for example:  binary number = 110 decimal number = 2^0 * 0 + 2^1 * 1 + 2^2 * 1 = 1 * 0 + 2 * 1 + 4 * 1 = 0 + 2 + 4 = 6 Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void printDecimal( int num) { int decimal = 0; int twos = 1; // 2^0 = 1 initial value while (num > 0) { int temp = num

N-th Tribonacci Number Solution - The Coding Shala

Home >> Programming >> N-th Tribonacci Number  Hey there, welcome back to another post. In this post, we will learn how to solve the N-th Tribonacci Number problem and will implement its solution in Java. N-th Tribonacci Number Problem Statement The Tribonacci sequence Tn is defined as follows: T0 = 0, T1 = 1, T2 = 1, and Tn+3 = Tn + Tn+1 + Tn+2 for n >= 0. Given n, return the value of Tn.  Example 1:  Input: n = 4 Output: 4 Explanation: T_3 = 0 + 1 + 1 = 2 T_4 = 1 + 1 + 2 = 4 N-th Tribonacci Number Java Solution using Bottom-Up DP This problem is similar to the Fibonacci series. We can solve it using the Bottom-Up approach of dynamic programming. Time Complexity: O(n) Space Complexity: O(n) The space complexity can be reduced to O(1) by using variables to store the previous three values instead of using an array. Java Program:  class Solution { public int tribonacci( int n) { if (n == 0) return 0; if (n == 1 || n == 2

Java Program to Convert Decimal to Binary - The Coding Shala

Home >> Java Programs >> Convert Decimal to Binary  Hey there, welcome back to another post. In this post, we will learn how to convert decimal to binary in Java. Java Program to Convert Decimal to Binary You have given a decimal number. Write a Java program to convert decimal to binary. Example 1:  Input: 7 Output: 111 Input: 10 Output: 1010 Decimal to Binary Conversion using Array Approach To convert decimal to binary we can follow the below steps: Store the remainder in the array when we divide the number by 2. Divide the number by 2. Follow the above two steps until the number is above 0. Print the array in reverse order. For example:  4 % 2 = 0 => 4/2 = 2 2 % 2 = 0 => 2/2 = 1 1 % 2 = 1 => 1/2 = 0 Binary of 4 is: 100 Java Program:  import java.util.ArrayList; import java.util.List; import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void printBinary( int num) {
