To delimit a command or statement name from its parameters, use a space or a comma. For example, you can specify ATTACH,FILESERVER or ATTACH FILESERVER.
To delimit parameters from their values, use an equal sign or parentheses. For example, specify REUSE=YES or REUSE(YES).
When you specify multiple values for a parameter, always enclose the values in parentheses and separate them with commas or spaces. For example, specify OPTION(TRIM,DEFER).
