CONVERT

Syntax

Purpose

CONVERT returns smallest integer greater than or equal to expr.

Converts a character string from one character set to another.

• The char argument is the value to be converted.

• The dest_char_set argument is the name of the character set to which char is converted.

• The source_char_set argument is the name of the character set in which char is stored in the database. The default value is the database character set.

Both the destination and source character set arguments can be either literals or columns containing the name of the character set.

For complete correspondence in character conversion, it is essential that the destination character set contains a representation of all the characters defined in the source character set. Where a character does not exist in the destination character set, a replacement character appears. Replacement characters can be defined as part of a character set definition.

Example

SELECT CONVERT('Groß', 'US7ASCII', 'WE8HP')
   "Conversion" FROM DUAL;

Conversion
----------
Gross
