2. MySQL
Set of My-SQL functions was decided in the previous workshop(s) should continue !

1. CONCAT(str1,str2..)
2. LOWER(str.) , UPPER(str.)
3. LENGTH(str.)
4. LTRIM(str.) , RTRIM(str.) ,TRIM(str.)
5. LEFT(str., len) , RIGHT(str., len) , MID(str, pos, len) and SUBSTRING()

3. MySQL Date functions :- Numeric functions :-
1. NOW() , TIME(expr) and CURDATE()
2. DAY(date) , MONTH(date) and YEAR(date)
3. DAYNAME(date) and MONTHNAME(date)
4. DATE(expr)
Numeric functions :-
1. ABS(x) 2. EXP()
3. POW() 4. MOD()
5. ROUND() 6. SQRT()

4. MySQL Aggregate or Summary or Group functions:-
COUNT() : For counting number of the rows of the specified column.
SUM() : For summing of the non null values in the specified column.
AVG() : For averaging of the non null values in the specified column.
MIN() : For finding minimum of the non null values in the specified column.
MAX() :For finding maximum of the non null values in the specified column.

5. MySQL In the previous years patterns:-
Marking scheme of all five units in annual exam. paper.
Five units of the syllabus (80 marks paper): (=16x5)
Five units of the same syllabus (annual pattern) marks : ( =12x5)
Now in the current semester based system of
Five units of Sem-V (60 marks)+ Sem-VI (60 marks)
Total 120 marks : (=24x5) with out options.
With 50 % options 180 marks : (=36x5)

6. MySQL Total marks for MySQL is 10+10+4 =24 and with options 15+15+6=36
Marking scheme of MySQL in Question Paper:-
Q 2. A) Attempt any two sub-questions from a, b, c in MySQL
a) MySQL (5)
b) MySQL (5)
c) MySQL (5)
Q 3. A) Attempt any two sub-questions from a, b, c in MySQL
Q 4.
B) Attempt any four sub-questions from d, e, f, g, h, i in MySQL (Multiple Choice) (4)
d) MySQL
e) MySQL
f) MySQL
g) MySQL
h) MySQL
i) MySQL
Total marks for MySQL is =24 and with options =36

7. MySQL Five marks six questions can be 1. Create table question :-
(This question must be carefully designed so that no variation in marking schemes at the paper assessment. )
2. Simple queries, sorting queries, queries with condition(s), queries with calculating results with new heading(s) using existing columns.
3. Group/ Summary Queries using Group by clause (& using group functions : COUNT(), SUM(), AVG(), MAX() & MIN()
4. Multi table queries: Simple joins (INNER JOIN) only
5. Nested queries ( Only up to two levels) : Subqueries.

8. MySQL
6. i) Changing table structure ( Alter table…add/drop/change/ modify/rename …etc )
ii) Adding / deleting /updating rows/ row contains in the existing table.
iii) Renaming /Removing databases, tables.
Displaying list of existing databases, tables in a existing database.
iv) Simple transaction:- START, COMMIT & ROLLBACK.
v) Queries using MySQL functions.

9. MySQL Discussion with reference to MySQL :-
To define exact set of MySQL functions.
Queries using limit clause can be included as scope of syllabus.
To define exact marking scheme of multi-table queries. (Since in some question papers one query 5 marks or in some papers its carry 2 marks.)
In multi-table queries Self Join discuss or not?
