Learn more about PLSQL
PLSQL is one block-structured language with which a developer can combine SQL with procedural statements. The significant advantage of this system is that all the statements are passed to the Oracle engine, decreasing traffic and increasing processing speed.
- This procedural language can provide many functions such as decision making and iteration all at once.
- In just one block, using a single command, several queries can be executed by PLSQL.
- Units of procedures, packages, triggers, functions, and types are all stored for reuse in the database.
- Another fascinating feature of PLSQL is the exception handling block which enables handling of occurring exceptional functions.
- Functions of PLSQL are very portable with computer operating systems (hardware) with Oracle present in it.
- Lastly, it also provides extensive checking of errors.
Important features of PLSQL
This procedural extension programming language has various important features such as error handling mechanism, high-performance, high security, and reduced network traffic.
- It is a portable, high-performance process language that provides an OS-independent programming environment.
- PLSQL is one high-performance transaction-processing language.
- With PLSQL, the codes can be reused, which will save time by eliminating codes repeatedly.
- Error detection and handling by this programming language are done in a user-friendly manner.
- The language also consists of conditional statements and loop statements that are difficult to understand and make the task even easier.
- The language has blocks of codes that can be nested internally and amongst each other. All the blocks have specific functionality that aids in the construction of specific logical modules.
- With the Oracle engine, simultaneous processing of multiple SQL statements as one single block is possible. This increases performance and reduces network traffic.
- Applications written within PLSQL are portable with any operating system.
