oracle - cat a file value in plsql

Question

I am just wondering is there any way that we can print the values of a file in plsql

thing is:

I select 5 columns from a table and one of the column is a path/file.
I want to print the contents of the file

I know its complex but will be good if someone shows me a way.

Answer 1

一种方法是使用UTL_FILE读取文件，并使用dbms_output打印它。
请注意，您必须告诉 ORACLE 哪些路径可以保存文件（请参阅此处）

另一种方法可能是使用 java 存储过程，请参阅此AskTom

Answer 2

这取决于您想要实现什么或上下文是什么。您可能对“外部表”或 utl_file 包或 CLOB 数据类型感兴趣。http://docs.oracle.com/cd/B19306_01/server.102/b14220/schema.htm#sthref777
