HEXTORAW converts char containing hexadecimal digits in the CHAR, VARCHAR2, NCHAR, or NVARCHAR2 data type to a raw value.
This function does not support CLOB data directly. However, CLOBs can be passed in as arguments through implicit data conversion.
See Also:
"Data Type Comparison Rules" for more information.The following example creates a simple table with a raw column, and inserts a hexadecimal value that has been converted to RAW:
CREATE TABLE test (raw_col RAW(10));
INSERT INTO test VALUES (HEXTORAW('7D'));
The following example converts hexadecimal digits to a raw value and casts the raw value to VARCHAR2:
SELECT UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('4041424344'))
FROM DUAL;
UTL_RAW.CAST_TO_VARCHAR2(HEXTORAW('4041424344'))
