Purpose

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.

You can use this function in conjunction with any of the XML functions to generate a date in the database format rather than the XML Schema standard format.

Examples

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)
