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.

Examples

Example 8-69 Using REMBYTES to Remove a Substring

This example shows how to remove the substring there from the text value hellotherejoe.

The statement

SHOW REMBYTES('hellotherejoe', 6, 5)

produces the following output.

hellojoe
