CHAR
CHAR
Syntax
84
Returns a character string with the first character having an ASCII value equal to the argument
expression. CHAR is identical to CHR but provides ODBC-compatible syntax.
Example This example illustrates the CHAR function:
Notes • The argument to the function must be of type INTEGER, TINYINT, or SMALLINT.
CHR
Syntax
CHAR ( integer_expression )
SELECT *
FROM customer
WHERE SUBSTR (zip, 1, 1) = CHAR (53) ;
• The result is of type CHARACTER.
• If the argument integer_expression evaluates to NULL, the result is NULL.
• The CHAR and CHR functions are character-set dependent and support single-byte and
multi-byte characters. If integer_expression is a valid character encoding integer value
in the current SQL server character set, the function returns the correct character. If it is
not a valid character, the function returns a NULL value.
Compatibility
ODBC compatible

CHR ( integer_expression )
Example This example illustrates the CHR function and the SUBSTR (substring) function:
SELECT *
FROM customer
WHERE SUBSTR (zip, 1, 1) = CHR (53) ;
Notes • The argument to the function must be of type INTEGER, TINYINT, or SMALLINT.
• The result is of type CHARACTER.
• If the argument integer_expression evaluates to NULL, the result is NULL.
