Arguments

• 'character_string'
  Is a string of Unicode character data. character_string is sysname and is limited to 128 characters. Inputs greater than 128 characters return NULL.

• 'quote_character'
  Is a one-character string to use as the delimiter. Can be a single quotation mark ( ' ), a left or right bracket ( [ ] ), or a double quotation mark ( " ). If quote_character is not specified, brackets are used.

Examples

The following example takes the character string abc[]def and uses the [ and ] characters to create a valid SQL Server delimited identifier.

SELECT QUOTENAME('abc[]def')

Here is the result set.

(1 row(s) affected)

Notice that the right bracket in the string abc[]def is doubled to indicate an escape character.
