oracle export stored procedure

Oracle is one of the relational database management systems currently widely used in enterprise application systems. In daily database management, we often need to export stored procedures for backup or deployment. This article will introduce how to export Oracle stored procedures.

1. What is Oracle stored procedure?

In Oracle database, stored procedures (Stored Procedures) can be regarded as an encapsulated database object. Its complete definition contains multiple SQL statements and can be regarded as a block-level program unit. , consisting of a series of SQL statements and other program structures written in PL/SQL as the basic language. Stored procedures can provide us with an independent processing process, which facilitates unified operations on large amounts of data, and can also improve the efficiency and security of the database.

2. How to export Oracle stored procedures

Oracle provides a variety of ways to export stored procedures, and the most commonly used ones are to use SQL*Plus tools and Oracle SQL Developer. Next, this article will focus on these two tools.

1.SQL*Plus tool export

SQLPlus is an Oracle database management tool. It can execute Oracle commands through the command line and also has batch functions similar to file processing. processing mode. In SQLPlus, you can use the following command to export stored procedures:

SQL> SET SERVEROUTPUT ON

SQL> SET LONG 20000

SQL> SPOOL /home/backup/procedure.sql

SQL> SELECT TEXT FROM ALL_SOURCE

      WHERE TYPE ='PROCEDURE'

      AND OWNER ='my_user_id'

      AND NAME ='my_proc_name';

SQL> SPOOL OFF

Analyze this code:

• SET SERVEROUTPUT ON: You can control the execution The results returned by the SQL statement are output to the SQL*Plus window;
• SET LONG 20000: Define the length of each field in the generated output line;
• SPOOL /home/backup/ procedure.sql: Define the output file name and storage directory;
• SELECT TEXT FROM ALL_SOURCE...: Use the SELECT statement to obtain the complete definition of the stored procedure;
• SPOOL OFF: End Spooling output, The export file is completed.

Through the above steps, we can easily export the stored procedures in the Oracle database to the local disk.

2.Oracle SQL Developer export

In addition to using the SQL*Plus tool to export, you can also use the export function in Oracle SQL Developer. SQL Developer is a free, powerful graphical database development and management tool. It can provide an object-oriented user interface for database management, and also supports stored procedure export.

In SQL Developer, to export a stored procedure, you can follow the steps below:

• In SQL Developer, connect to the database instance where you want to export the stored procedure;
• Right-click the "Procedures" directory and select the "Export" option;
• In the pop-up window, select the object to be exported, such as a schema name or a specified Stored procedure name;
• Set export options, including export format, file name, directory and encoding, and other required options;
• After completing the settings, click "Finish" ) button to start exporting the stored process.

3. Summary

This article mainly introduces how Oracle exports stored procedures, specifically involving the two main tools of SQLPlus tool and Oracle SQL Developer. Although the SQLPlus tool is not beautiful enough, its simplicity, fewer account permission issues, and better compatibility make it more advantageous in certain scenarios; while Oracle SQL Developer is more complicated, but it provides Many rich options allow you to manage database objects more granularly. As the saying goes, there are no good or bad tools, they just have different uses. The specific choice should be based on the actual scenario.
