Case and decode are conditional expressions in PL/SQL used for data manipulation.
CASE is used for conditional logic in SQL statements, while DECODE is used for conditional logic in SELECT statements.
CASE is more flexible and can handle multiple conditions, while DECODE is limited to one condition.
CASE can be used in both SQL and PL/SQL, while DECODE is specific to SQL.
Example of CASE: SELECT CASE WHEN condition1 THEN r...
Primary key uniquely identifies each record in a table, while foreign key establishes a link between two tables.
Primary key ensures uniqueness and cannot have null values
Foreign key establishes a relationship between tables based on the primary key of another table
Example of primary key: EmployeeID in an Employee table
Example of foreign key: DepartmentID in an Employee table linking to DepartmentID in a Department tabl
Rank assigns unique ranks to each distinct row, while Dense Rank assigns consecutive ranks without gaps.
Rank may have gaps in the ranking sequence, while Dense Rank does not.
Rank assigns the same rank to rows with the same values, while Dense Rank assigns different ranks.
Rank function is non-consecutive, while Dense Rank function is consecutive.
Procedures are used to perform an action, while functions return a value.
Procedures do not return a value, while functions do.
Functions can be called from SQL queries, while procedures cannot.
Functions must return a value, while procedures do not necessarily have to.
No, a package body cannot be used without a package specification.
A package body must always be associated with a package specification.
The package specification defines the public interface of the package, while the package body contains the implementation details.
Attempting to use a package body without a corresponding package specification will result in compilation errors.
Use a SQL query with GROUP BY and HAVING clause to find duplicate values in a database.
Use GROUP BY clause to group the values that are duplicated.
Use HAVING clause to filter out the groups that have more than one occurrence.
Example: SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name HAVING COUNT(*) > 1;
Group by and having clause are used together to filter groups based on specified conditions.
Group by clause is used to group rows that have the same values into summary rows.
Having clause is used to filter groups based on specified conditions.
Example: SELECT department, AVG(salary) FROM employees GROUP BY department HAVING AVG(salary) > 5000;
Substr function extracts a substring from a string, while Instr function returns the position of a substring within a string.
Substr function syntax: SUBSTR(string, start_position, length)
Example: SUBSTR('Hello World', 7, 5) will return 'World'
Instr function syntax: INSTR(string, substring)
Example: INSTR('Hello World', 'World') will return 7
Writing a SQL query with a subquery involves nesting one query inside another to retrieve specific data.
Start by writing the main query that will retrieve the primary data
Identify the criteria for the subquery to filter the results
Enclose the subquery within parentheses and use it in the WHERE or FROM clause of the main query
Ensure that the subquery returns a single value or a single column result
Char is fixed length, varchar is variable length with max 4000 bytes, varchar2 is variable length with max 32767 bytes.
Char is fixed length and always right-padded with spaces, while varchar and varchar2 are variable length.
Varchar can store up to 4000 bytes of data, while varchar2 can store up to 32767 bytes.
Char is less efficient in terms of storage compared to varchar and varchar2.
No, it is not possible to combine two tables with differing data and columns without utilizing joins.
Joins are necessary to combine tables based on a common column or key.
Different data and columns require a join to match and merge the data properly.
Examples of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.
Yes, it is possible to update data in a view using INSTEAD OF triggers.
Views are virtual tables that display data from one or more tables.
By using INSTEAD OF triggers, you can update data in a view by specifying the logic to handle the update operation.
The trigger intercepts the update operation on the view and executes the specified logic to update the underlying tables.
For example, you can create an INSTEAD OF trigge...

They allow for flexibility in querying the database based on user input or other conditions.
Dynamic cursors can be used to handle varying result sets or conditions in a more efficient manner.
Example: Using a dynamic cursor to search fo...

A package in PL/SQL is a collection of related procedures, functions, variables, and other constructs.
A package consists of two parts: package specification and package body.
The package specification defines the public interface of the package, including declarations of variables, constants, cursors, procedures, and functions.
The package body contains the actual implementation of the procedures and functions declared i...
