Error- ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion

I am attempting to read a BLOB message and display it as a variable in one of my procedures, but am getting the error below:

Error - ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 9923, maximum: 2000)

I have googled and found a suggestion to trim the BLOB message as below, but I would rather display the complete BLOB message as a string.

UTL_RAW.CAST_TO_VARCHAR2(dbms_lob.substr(variable_name,2000,1))

How can I display the complete message? Is there a setting on either the database or procedure level that I can change?

Solution

  • I got this working by using the option described here:
