QueryInterpolator

String interpolation using the "b" prefix to build SQL statements. In general, the generated string is passed to "sqlBuilder.+=". When preceded by '', the following characters have special meaning:

• '(': if(!skipParens) sqlBuilder += '('

• ')': if(!skipParens) sqlBuilder += ')'

• '[': Add a '(' plus newline and increase indentation

• '[': Decrease indentation and add a newline plus ')'

• '{': Like '[' but only if(!skipParens)

• '}': Like ']' but only if(!skipParens)

• 'n': Add a newline plus indentation

If 'slick.sqlIndent' is not set in application.conf, no newlines are inserted and indentation is replaced by a single space character.

Variables inside the string can be prefixed by another symbol before the standard '$' escape character to modify their meaning:

• '`' (before a String variable s): sqlBuilder += quoteIdentifier(s)

• '`' (before a Symbol variable s): sqlBuilder += symbolName(s)

• '!' (before a Node variable n): expr(n, true)

• no prefix (before a Node variable n): expr(n)

• no prefix (before a String variable s): sqlBuilder += s

• no prefix (before an AnyVal variable v): sqlBuilder += String.valueOf(v)

The identifiers sqlBuilder, skipParens, expr, quoteIdentifier and symbolName are resolved dynamically at the call site.
