Most database system do a specific job. For example, a simple system might immediate the customer for an worker wide range, then upgrade series in the EMP and DEPT platforms. In this situation, you know the cosmetics of the UPDATE declaration at precompile time. That is, you know which platforms might be modified, the restrictions described for each desk and line, which content might be modified, and the datatype of each line.

1. What Is The Rule of Oracle Parse SQL
Most database system do a specific job. For example, a
simple system might immediate the customer for an worker
wide range, then upgrade series in the EMP and DEPT
platforms. In this situation, you know the cosmetics of the
UPDATE declaration at precompile time. That is, you know
which platforms might be modified, the restrictions described
for each desk and line, which content might be modified, and
the datatype of each line.

2. However, some applications must agree to (or build) and
procedure a number of SQL statements at run time. For
example, a general-purpose review author must develop
different SELECT statement for the various reviews it
produces

3. Advantages and Drawbacks of Powerful SQL
Host applications that agree to and procedure dynamically
described SQL statement are handier than simply included
SQL applications. Powerful SQL statement can be designed
interactively with feedback from customers having little or no
understanding of SQL.

4. However, some dynamic concerns require complicated
development, the use of special information components, and
more playback handling. While you might not find the
additional handling time, you might find the development
difficult unless you completely understand dynamic SQL
ideas and methods.

5. Use Powerful SQL
Written text of the SQL declaration (commands, conditions, and so on)
The range of wide range variables
The datatypes of wide range variables
Sources to databases things such as content, indices, series, platforms, usernames,
and views
Requirements for Powerful SQL Statements
To signify an energetic SQL declaration, a personality sequence must contain the
writing of a real SQL declaration, but not contain the EXEC SQL stipulation, or the
declaration terminator, or any of the following included SQL commands:

6. How Powerful SQL Claims are Processed
Typically, a program encourages the consumer for the writing of an SQL declaration and of the
variety factors used in the statement. Oracle then parses the MySQL declaration to make sure it
satisfies format guidelines.
Next, Oracle holds the variety factors to the SQL declaration. That is, Oracle gets the details of the
variety factors so that it can study or create their principles.
