REMBYTES

The REMBYTES function removes one or more bytes from a text expression and returns the value that remains.

Return Value

TEXT

Syntax

REMBYTES(text-expression start [length])

Arguments

text-expression: The TEXT expression from which REMBYTES removes bytes. When the characters to be removed from text-expression contain embedded line breaks, these breaks are also removed. Other line breaks are preserved. Removed line breaks are not counted toward the total number of characters removed.

Tip:
When you must use this function on NTEXT values, use the CONVERT or TO_CHAR function to convert the NTEXT value to TEXT.
start: An INTEGER that represents the character position at which to begin removing characters. The position of the first character in text-expression is 1. When the value of start is greater than the length of text-expression, REMBYTES simply returns text-expression.
length: An INTEGER that represents the number of characters to be removed. When length is not specified, only the character at start is removed.
