SQL queries can contain ? in other places such as literals. Presumably use of SQL interface placeholders are determined by some level of parsing, else literal use of ? is substituted. Similar regular expressions and LIKE (Where ? is a plain character). This may or may not be the intent. What do these interfaces do in this situations? > or any chance to get '$' symbol accepted as a synonym for '?' symbol in > the BRQL spec? The doc does not define the syntax. It just gets used in examples.
