![]() If this is an ASCII or UTF8 platform, no conversion needed. If this is an EBCDIC platform, convert the encoded text to EBCDIC If this is a UTF16 platform, convert the encoded text to UTF16 The mime header tags are appended and prepended.įinally, the string is converted to the base character set of the database: The converted string is encoded to either quoted-printable or base64 encoded format. You can see that the first query containing WHEN NULL did not replace NULL. The mimeheader encoding process includes conversion of the buf input string to the character set specified by the encode_charset parameter. Oracle PL/SQL to Java COBOL to Oracle PL/SQL. If NULL, the database character set is selected as a default value. The value is specified as the input parameter encode_charset. If NULL, quoted-printable encoding is selected as a default value. The ENCODING input parameter accepts as valid values UTL_ENCODE.QUOTED_PRINTABLE or UTL_ENCODE.BASE64 or NULL. The value is either "Q" or "B" for quoted-printable encode or base64 encoding respectively. In Oracle version 8.1.6, Oracle introduced the CASE Statement, which allowed the. Before Oracle 8.1 version, only DECODE function was there for providing IF-THEN-ELSE functionality and this can compare only discrete values (Not in range). Decode Function and Case Statement is used to transform data values at retrieval time. The buf input parameter is the text to be encoded and becomes the. DECODE and CASE both provides IF-THEN-ELSE functionality in Oracle SQL. Reads the RAW input string and encodes it to the corresponding uuencode format string DECODE result type is first decoded expression type, all others are. Decode statement can be used with only SQL DML statements like SELECT, INSERT, UPDATE, DELETE. Reads the RAW uuencode format input string and decodes it to the corresponding RAW string Decode Function is used to compare values in the decode function and returns the result that match with comparison value. Its an alternative for the CASE statement which was introduced in Oracle 8. Reads the RAW input string and encodes it to the corresponding quoted printable format stringĭecodes a character set sensitive text stringĮncodes a character set sensitive text string The decode function can be used in SQL for and IF-THEN-ELSE construction. Reads the varchar2 quoted printable format input string and decodes it to the corresponding RAW string Reads the base 64-encoded RAW input string and decodes it to its original RAW valueĮncodes the binary representation of the RAW value into base 64 elements and returns it in the form of a RAW string Java webservice Base64-decodes the file and. I save this file before doing anything else (just for a test): as expected, the file is corrupt (it's a Base64-string, this is normal). Table 264-1 UTL_ENCODE Package Subprograms Subprogram Basically, it boils down to: PL/SQL side uploads a PDF file, then Base64-encodes this file, then sends it to my REST webservice.
