Using SQL Statements in Error Exceptions

Question

Is there any way to include SQL statements within my catch routines (i.e.
catch (java.io.IOException ex) {
System.out.println("An error occurred whilst writing to the message buffer: " + ex);
#sql { INSERT INTO DEBUG_TBL(CURRENT_DT,PROGRAM_ID,DEBUG__MESG) VALUES (SYSDATE,'TEST',:ex) };
#sql { COMMIT };
As it stands I get the following error upon compile:
Error: Unsupported Java type for host item (at position#1): java.io.IOException
Any help would be greatly appreciated.
Thx,
Boybles

You can use SQL statements in your catch blocks, just not SQL statements that use Java types which do not map to SQL.
You cannot pass exceptions from Java to SQL. You can catch a SQL exceptions as a SQLException in Java. However, any exception that is thrown by a Java Stored Procedure (including SQLException) is rendered as an "Uncaught Java exception" in SQL.
When you receive a SQLException there is information about the originator, the error message, etc. in the exception object. See:
http://technet.oracle.com/docs/products/oracle8i/doc_library/817_doc/java.817/a83723/keyprog5.htm#1004462
While you cannot insert a Java exception per se into a table, you can extract the message string(s)/code and insert that in a table.
