This package is necessary because normal SQL functions do not operate on RAWs, and PL/SQL does not allow overloading between a RAW and a CHAR datatype. UTL_RAW also includes subprograms that convert various COBOL number formats to, and from, RAWs. UTL_RAW is not specific to the database environment, and it may actually be used in other. RAW is a variable-length datatype like the VARCHAR2 character datatype, except Oracle Net Services which connects user sessions to the instance and the Import and Export utilities do not perform character conversion when transmitting RAW or LONG RAW data. In contrast, Oracle Net Services and Import/Export automatically convert CHAR, VARCHAR2. Note: Oracle discourages the use of the CONVERT function in the current Oracle Database release. The return value of CONVERT has a character datatype, so it should be either in the database character set or in the national character set, depending on the datatype. CAST does not support LONG, LONG RAW, or the Oracle-supplied types. When you use CAST to convert a CLOB value into a character datatype or a BLOB value into the RAW datatype, the database implicitly converts the LOB value to character or raw data and then explicitly casts the resulting value into the target datatype.
