In Oracle database, stored procedure is an important database object that allows users to define their own logical processing in the database. Stored procedures can contain a series of PL/SQL codes, can call other stored procedures and functions, and can use variables, conditional statements and loop control structures, and are very powerful. When we need to obtain Oracle stored procedures, we generally need to perform the following steps.
The first step is to log in to the Oracle database
We need to use Oracle SQL Developer or other database clients to connect to the target database.
Second step, query all stored procedures
In the connected database, run the following SQL statement to query all stored procedures and their corresponding SQL codes.
SELECT * FROM all_source WHERE type = 'PROCEDURE';
This SQL statement will return all stored procedure definitions, including the stored procedure name, creation time, modification time, and SQL code of the stored procedure.
The third step is to query specific stored procedures
If we only want to obtain specific stored procedures, we can run the following SQL statement:
SELECT * FROM all_source WHERE type = 'PROCEDURE' AND name = '存储过程名';
This SQL statement will return Specify the stored procedure definition and SQL code for the stored procedure name.
The fourth step is to export the stored procedure as a script file
If we want to export the stored procedure as a script file, we can use the Export function in Oracle SQL Developer. Open Oracle SQL Developer, select "Connections" in the left navigation bar, then right-click the target database, select "Export" -> "Database Objects", check "Procedures", and then specify the export path and file name. .
The fifth step, export the DDL script of the stored procedure
If we want to obtain the DDL script of the stored procedure, we can run the following SQL statement:
SELECT dbms_metadata.get_ddl('PROCEDURE','存储过程名','OWNER') FROM dual;
This SQL statement will The specified stored procedure DDL script will be returned, which can be saved as a text file.
Summary
The method to obtain Oracle stored procedures is relatively simple. You can use SQL to query all stored procedures, or query specific stored procedures. We can also export the stored procedure as a script file, or obtain the DDL script of the stored procedure. Using these methods can help us better understand and manage stored procedures in Oracle database.
