The column name in the OUTPUTS clause can be a quoted string (possibly multi-word and with spaces). The only illegal characters in the quoted string are single quotes, double quotes, backslashes, and the character with code zero.
The column name can also be enclosed in square brackets. Quoted identifiers surrounded by square brackets can contain any character except the following characters: single quotes, double quotes, square brackets, backslashes, and the character with code zero.
The double quotes or square brackets are not captured in the column name.
