SUFFIX
SUFFIX
Syntax
128
– Bigger than 0 and the column’s row data exceeds the column’s SQL width, the
function returns the substring.
• If length is not specified, the function returns the substring from start_pos to the end
of the literal.
• The function returns the end of the column’s row data if the length of the substring is not
bigger than the column’s SQL width. Otherwise, the function returns the substring
truncated to the column’s SQL width.
Compatibility
ODBC compatible
Returns the substring of a character string starting after the position specified by start_pos and
the second char_expression, to the end of the string.
SUFFIX (char_expression , start_pos , char_expression )
char_expression
Evaluates to a character string, typically a character-string literal or column name. If the
expression evaluates to NULL, SUFFIX returns NULL.
start_pos
Evaluates to an integer value. SUFFIX searches the string specified in the first argument
starting at that position. A value of 1 indicates the first character of the string.
char_expression
Evaluates to a single character. SUFFIX returns the substring that begins with that
character. If SUFFIX does not find the character after start_pos, it returns NULL. If the
expression evaluates to more than one character, SUFFIX ignores all but the first character.
Example This example illustrates two ways to use the SUFFIX function:
