TO_CHAR (character) converts NCHAR, NVARCHAR2, CLOB, or NCLOB data to the database character set. The value returned is always VARCHAR2.
When you use this function to convert a character LOB into the database character set, if the LOB value to be converted is larger than the target type, then the database returns an error.
The following example interprets a simple string as character data:
SELECT TO_CHAR('01110') FROM DUAL;
TO_CH
-----
01110
Compare this example with the first example for TO_CHAR (number).
The following example converts some CLOB data from the pm.print_media table to the database character set:
SELECT TO_CHAR(ad_sourcetext) FROM print_media
WHERE product_id = 2268;
TO_CHAR(AD_SOURCETEXT)
