SQL functions for manipulating RAW datatypes.
Functions:
CAST_FROM_BINARY_INTEGER Function
Returns the binary representation of a BINARY_INTEGER (in RAW).
CAST_FROM_NUMBER Function
Returns the binary representation of a NUMBER (in RAW).
CAST_TO_BINARY_INTEGER Function
Casts the binary representation of a BINARY_INTEGER (in RAW) into a BINARY_INTEGER
CAST_TO_NUMBER Function
Casts the binary representation of a NUMBER (in RAW) into a NUMBER. If include_length is TRUE, the first byte of r encodes the number of bytes in r (
CAST_TO_RAW Function
Converts a VARCHAR2 represented using n data bytes into a RAW with n data bytes.
CAST_TO_VARCHAR2 Function
Converts a RAW represented using n data bytes into VARCHAR2 with n data bytes.
CONCAT Function
Concatenates up to 12 RAWs into a single RAW.
LENGTH Function
Returns the length in bytes of a RAW r.
SUBSTR Function
Returns len bytes, starting at pos from RAW r.
TRANSLATE Function
Translates the bytes in the input RAW r according to the bytes in the translation RAWs from_set and to_set.
TRANSLITERATE Function
Converts the bytes in the input RAW r according to the bytes in the transliteration RAWs from_set and to_set.
OVERLAY Function
Overlays the specified portion of target RAW with overlay RAW, starting from byte position pos of target and proceding for len bytes.
COPIES Function
Returns n copies of r concatenated together.
XRANGE Function
Returns a RAW containing all valid 1-byte encodings in succession, beginning with the value start_byte and ending with the value end_byte.
REVERSE Function
Reverses a byte sequence in RAW r from end to end.
COMPARE Function
Compares RAW r1 against RAW r2.
CONVERT Function
Converts RAW r from character set from_charset to character set to_charset and returns the resulting RAW.
BIT_AND Function
Performs bitwise logical and of the values in RAW r1 with RAW r2 and returns the anded result RAW.
BIT_OR Function
Performs bitwise logical or of the values in RAW r1 with RAW r2 and returns the or'd result RAW.
BIT_XOR Function
Performs bitwise logical exclusive or of the values in RAW r1 with RAW r2 and returns the xor'd result RAW.
BIT_COMPLEMENT Function
Performs bitwise logical complement of the values in RAW r and returns the complement'ed result RAW.
