List of all 400+ Team scores in the cricket ODI matches

The first One-day International match was played between Australia and England on 5 January 1971. Since then the first 400+ plus was scored by the Australian team in 2006. As on January 2020, 21 scores have been chalked out in the ODI cricket by 6 teams. In this article, we have published the list of all 400+ ODI scores.

List of all 400+ Team scores in the ODI matches;

Indian team’s highest score in ODI

The first 400+ score of the Indian team was against Bermuda in world cup 2007. Indian team scored 413/5 with the help of 114 runs by Sehwag, 89 by Sourav Ganguly and 83 runs by Yuvraj Singh.

The highest score of the Indian team in ODI is 418/5. The Indian team had scored these runs with the help of a double century by Virender Sehwag. He scored his career-best 219 runs in this match played at Indore on Dec 8, 2011.

Some interesting records about 400+ score;

1. Till date, 6 teams have scored 400+ run mark in ODIs on 21 occasions.

2. South Africa is the only team that has scored 400+ runs in ODIs 6 times and winning all matches.

3. The Indian team has scored 400+ runs on five occasions and won all matches.

4. England team has scored 400+ runs on five occasions and won all matches.

5. Australian and Sri Lanka team have scored 400+ on just 2 occasions, losing one and winning one.

6. New Zealand & West Indies are the other two teams that also have scored 400+ score one time each.

So this was the complete list of all 400+ scores in the ODI matches. I hope the Indian team will supercede South Africa and register the most number of 400 plus scores in the ODI cricket.

List of universities in India

view of University of Madras from the beach

The University of Madras, established 1857, is one of the three oldest modern state universities in India, the others being the University of Calcutta and the University of Mumbai.

The higher education system in India includes both private and public universities. Public universities are supported by the Government of India and the state governments, while private universities are mostly supported by various bodies and societies. Universities in India are recognised by the University Grants Commission (UGC), which draws its power from the University Grants Commission Act, 1956. In addition, 15 Professional Councils are established, controlling different aspects of accreditation and co-ordination.

The types of universities include:

  • Central universities, or Union universities, are established by an Act of Parliament and are under the purview of the Department of Higher Education in the Union Human Resource Development Ministry. As of 12 December 2018, The list of central universities published by the UGC includes 49 central universities.
  • State universities are run by the state government of each of the states and territories of India and are usually established by a local legislative assembly act. As of 6 October 2017, the UGC lists 367 state universities. The oldest establishment date listed by the UGC is 1857, shared by the University of Mumbai, the University of Madras and the University of Calcutta. Most State Universities are affiliating universities administering many affiliated colleges (often located in small towns) that typically offer a range of undergraduate courses, but may also offer post-graduate courses. More established colleges may even offer Ph.D. programs in some departments with the approval of the affiliating university.
  • Deemed university, or “Deemed to be University”, is a status of autonomy granted by the Department of Higher Education on the advice of the UGC, under Section 3 of the UGC Act. As of 6 October 2017, the UGC lists 123 deemed universities.[12] According to this list, the first institute to be granted deemed university status was Indian Institute of Science, which was granted this status on 12 May 1958. In many cases, the same listing by the UGC covers several institutes. For example, the listing for Homi Bhabha National Institute covers the Institute of Mathematical Sciences, the Indira Gandhi Centre for Atomic Research and other institutes.
  • Private universities are approved by the UGC. They can grant degrees but they are not allowed to have off-campus affiliated colleges. As of 6 October 2017, the UGC list of private universities lists 282 universities.

These four types of universities total 821 universities together. There are universities of some kind in each of the 29 states of India as well as three of the union territories: Chandigarh, Delhi and Puducherry. The state with the most universities is Rajasthan with 76 universities, and Rajasthan has also by far the most private universities, 46 in number. Tamil Nadu is the state with the most deemed universities, numbering 28[12] and Uttar Pradesh has the most state universities, 29. Uttar Pradesh also has six central universities, the largest number of all the states and territories.

Apart from the above universities, other institutions are granted the permission to autonomously award degrees. However, they do not affiliate colleges and are not officially called “universities” but “autonomous organizations” or “autonomous institutes”. They fall under the administrative control of the Department of Higher Education. These organisations include the Indian Institutes of Information Technology, Indian Institutes of Technology, the National Institutes of Technology, the All India Institutes of Medical Sciences, the Indian Institutes of Science Education and Research, the Indian Institutes of Management (though these award diplomas, not degrees) and other autonomous institutes. These institutes are not listed below.

Also not listed are institutes which are under the control of the professional councils, without an approval of the UGC, e.g. Agricultural Universities, which are under the control of the Agricultural Education Division of the Indian Council of Agricultural Research (ICAR), one of the professional councils.

The University Grants Commission (UGC) has also released the list of 24 fake Universities operating in India. UGC has said that these 24 self-styled, unrecognised institutions functioning in contravention of the UGC Act have been declared as fake and are not entitled to confer any degrees.

List of SQL Commands

SQL, Structured Query Language, is a programming language designed to manage data stored in relational databases. SQL operates through simple, declarative statements. This keeps data accurate and secure, and it helps maintain the integrity of databases, regardless of size.

Here’s an appendix of commonly used commands.

COMMANDS

ALTER TABLE

ALTER TABLE table_name 
ADD column_name datatype;

ALTER TABLE lets you add columns to a table in a database.

AND

SELECT column_name(s)
FROM table_name
WHERE column_1 = value_1
  AND column_2 = value_2;

AND is an operator that combines two conditions. Both conditions must be true for the row to be included in the result set.

AS

SELECT column_name AS 'Alias'
FROM table_name;

AS is a keyword in SQL that allows you to rename a column or table using an alias.

AVG()

SELECT AVG(column_name)
FROM table_name;

AVG() is an aggregate function that returns the average value for a numeric column.

BETWEEN

SELECT column_name(s)
FROM table_name
WHERE column_name BETWEEN value_1 AND value_2;

The BETWEEN operator is used to filter the result set within a certain range. The values can be numbers, text or dates.

CASE

SELECT column_name,
  CASE
    WHEN condition THEN 'Result_1'
    WHEN condition THEN 'Result_2'
    ELSE 'Result_3'
  END
FROM table_name;

CASE statements are used to create different outputs (usually in the SELECT statement). It is SQL’s way of handling if-then logic.

COUNT()

SELECT COUNT(column_name)
FROM table_name;

COUNT() is a function that takes the name of a column as an argument and counts the number of rows where the column is not NULL.

CREATE TABLE

CREATE TABLE table_name (
  column_1 datatype, 
  column_2 datatype, 
  column_3 datatype
);

CREATE TABLE creates a new table in the database. It allows you to specify the name of the table and the name of each column in the table.

DELETE

DELETE FROM table_name
WHERE some_column = some_value;

DELETE statements are used to remove rows from a table.

GROUP BY

SELECT column_name, COUNT(*)
FROM table_name
GROUP BY column_name;

GROUP BY is a clause in SQL that is only used with aggregate functions. It is used in collaboration with the SELECT statement to arrange identical data into groups.

HAVING

SELECT column_name, COUNT(*)
FROM table_name
GROUP BY column_name
HAVING COUNT(*) > value;

HAVING was added to SQL because the WHERE keyword could not be used with aggregate functions.

INNER JOIN

SELECT column_name(s)
FROM table_1
JOIN table_2
  ON table_1.column_name = table_2.column_name;

An inner join will combine rows from different tables if the join condition is true.

INSERT

INSERT INTO table_name (column_1, column_2, column_3) 
VALUES (value_1, 'value_2', value_3);

INSERT statements are used to add a new row to a table.

IS NULL / IS NOT NULL

SELECT column_name(s)
FROM table_name
WHERE column_name IS NULL;

IS NULL and IS NOT NULL are operators used with the WHERE clause to test for empty values.

LIKE

SELECT column_name(s)
FROM table_name
WHERE column_name LIKE pattern;

LIKE is a special operator used with the WHERE clause to search for a specific pattern in a column.

LIMIT

SELECT column_name(s)
FROM table_name
LIMIT number;

LIMIT is a clause that lets you specify the maximum number of rows the result set will have.

MAX()

SELECT MAX(column_name)
FROM table_name;

MAX() is a function that takes the name of a column as an argument and returns the largest value in that column.

MIN()

SELECT MIN(column_name)
FROM table_name;

MIN() is a function that takes the name of a column as an argument and returns the smallest value in that column.

OR

SELECT column_name
FROM table_name
WHERE column_name = value_1
   OR column_name = value_2;

OR is an operator that filters the result set to only include rows where either condition is true.

ORDER BY

SELECT column_name
FROM table_name
ORDER BY column_name ASC | DESC;

ORDER BY is a clause that indicates you want to sort the result set by a particular column either alphabetically or numerically.

OUTER JOIN

SELECT column_name(s)
FROM table_1
LEFT JOIN table_2
  ON table_1.column_name = table_2.column_name;

An outer join will combine rows from different tables even if the join condition is not met. Every row in the left table is returned in the result set, and if the join condition is not met, then NULL values are used to fill in the columns from the right table.

ROUND()

SELECT ROUND(column_name, integer)
FROM table_name;

ROUND() is a function that takes a column name and an integer as arguments. It rounds the values in the column to the number of decimal places specified by the integer.

SELECT

SELECT column_name 
FROM table_name;

SELECT statements are used to fetch data from a database. Every query will begin with SELECT.

SELECT DISTINCT

SELECT DISTINCT column_name
FROM table_name;

SELECT DISTINCT specifies that the statement is going to be a query that returns unique values in the specified column(s).

SUM

SELECT SUM(column_name)
FROM table_name;

SUM() is a function that takes the name of a column as an argument and returns the sum of all the values in that column.

UPDATE

UPDATE table_name
SET some_column = some_value
WHERE some_column = some_value;

UPDATE statements allow you to edit rows in a table.

WHERE

SELECT column_name(s)
FROM table_name
WHERE column_name operator value;

WHERE is a clause that indicates you want to filter the result set to include only rows where the following condition is true.

WITH

WITH temporary_name AS (
   SELECT *
   FROM table_name)
SELECT *
FROM temporary_name
WHERE column_name operator value;

WITH clause lets you store the result of a query in a temporary table using an alias. You can also define multiple temporary tables using a comma and with one instance of the WITH keyword.

The WITH clause is also known as common table expression (CTE) and subquery factoring.
