SQL INSERT QUERY - The Coding Shala

Home >> Learn SQL >> SQL INSERT Query

SQL INSERT INTO STATEMENT

SQL 'INSERT INTO' Statement is used to insert a new row of data into the table. There are two basic statements to insert a new row into the table. First is by specifying columns names in which we want to insert data. The second way, if we want to add values in all the columns then we don't need to specify column names.
SQL INSERT INTO QUERY - The Coding Shala

SQL INSERT INTO Syntax 

The following is SQL INSERT INTO syntax with specifying columns name - 
INSERT INTO TABLE_NAME (column1, column2, column3,...columnN)   
                   VALUES (value1, value2, value3,...valueN);

We can use SQL INSERT INTO syntax without specifying columns names. In that case values for every column need to be inserted. 

INSERT INTO TABLE_NAME VALUES (value1,value2,value3,...valueN);

SQL INSERT INTO Examples - 

We have created the 'Persons' Table that is currently empty. The following query will insert data into the table - 

insert into Persons(PersonID, LastName, FirstName, Address, City)   
       values(1, 'Saini', 'Akshay', 'A-101', 'Pune');

Output -- 

PersonID     LastName     FirstName     Address     City  
 1            Saini         Akshay        A-1       Pune

  • We can write this query like this also -

insert into Persons values(1, 'last', 'first', 'A-101', 'Pune'); 
  
 PersonID     LastName     FirstName     Address     City  
 1             Saini       Akshay        A-101     Pune  
 1              last          first        A-101     Pune

  • If we want to insert into 'PersonID', and 'FirstName' then -

insert into Persons(PersonID, FirstName)    
     values(2, 'Akshay'); 
  
 PersonID     LastName     FirstName     Address     City  
 1          Saini         Akshay          A-101     Pune  
 1          last          first           A-101     Pune  
 2          null          Akshay          null     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) { ...

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; ...

LeetCode - Shuffle the Array Solution - The Coding Shala

Home >> LeetCode >> Shuffle the Array  In this post, we will learn how to solve LeetCode's Shuffle the Array problem and will implement its solution in Java. Shuffle the Array Given the array nums consisting of 2n elements in the form [x1,x2,...,xn,y1,y2,...,yn]. Return the array in the form [x1,y1,x2,y2,...,xn,yn]. Example 1: Input: nums = [2,5,1,3,4,7], n = 3 Output: [2,3,5,4,1,7]  Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7]. Example 2: Input: nums = [1,2,3,4,4,3,2,1], n = 4 Output: [1,4,2,3,3,2,4,1] Practice this problem on LeetCode: Click Here. Shuffle the Array Java Solution Approach 1: Using a new Array.

Java Program to Find GCD or HCF of Two Numbers - The Coding Shala

Home >> Java Programs >> Find GCD of Two Numbers  Hey there, welcome back to another post. In this post, we will learn how to find GCD or HCF of Two Numbers in Java. Java Program to Find GCD or HCF of Two Numbers The GCD (Greatest Common Divisor) or HCF (Highest Common Factor) of two numbers is the largest number that divides both of them. For example:  Number1: 6 (2 * 3) Number2: 9 (3 * 3) GCD or HCF of 6 and 9 is: 3 Find GCD of Two Numbers in Java using for Loop As we already know, GCD is the largest number that divides both numbers. We can start a for loop from 1 (because 1 divides all the numbers) to both numbers and if it divides both numbers then update GCD. Java Program:  import java.util.Scanner; /** * https://www.thecodingshala.com/ */ public class Main { public static void findGCD( int num1, int num2) { int gcd = 1; if (num1 == 0) { gcd = num2; } if (num2 == 0) { ...
