Ms. Veda created a table named Sports in a MySQL database, containing columns Game_id, P_Age, and G_name.
After creating the table, she realized that the attribute Category has to be added.
Help her to write a command to add the Category column.
Thereafter, write the command to insert the following record in the table: Game_id: G42 P\_Age: Above 18 G_name: Chess Category: Senior
-- Step 1: Add the Category column to the table ALTER TABLE Sports ADD Category VARCHAR(20); -- Step 2: Insert the given record into the table INSERT INTO Sports (Game_id, P_Age, G_name, Category) VALUES ("G42", "Above 18", "Chess", "Senior");Explanation: The
ALTER TABLE
statement is used to modify the structure of an existing table. The command ADD Category VARCHAR(20)
adds a new column named Category
with a data type of VARCHAR
and a maximum length of 20 characters.
The INSERT INTO
statement is used to add a new record to the table Sports
. The column names and their corresponding values are specified.
The resulting table Sports
will now include the record:
\[
\begin{array}{|c|c|c|c|}
\hline
\textbf{Game\_id} & \textbf{P\_Age} & \textbf{G\_name} & \textbf{Category} \\
\hline
G42 & Above 18 & Chess & Senior \\
\hline
\end{array}
\]
The SELECT statement when combined with \(\_\_\_\_\_\_\) clause, returns records without repetition.
In SQL, the aggregate function which will display the cardinality of the table is \(\_\_\_\_\_\).
myStr = "MISSISSIPPI" print(myStr[:4] + "#" + myStr[-5:])
The correct IUPAC name of \([ \text{Pt}(\text{NH}_3)_2\text{Cl}_2 ]^{2+} \) is:
