Wrote some unittests today and thought, this feature is useful when one wants easy sql statements (in, e.g. unittests). string typeName="Employee"; int[] ids=executeVector!int("select ID from Objects where type='\{typeName}'");

Meh, I find the placeholders to be much better (safer too): db.query("select id from objects where type = ?", typeName); I generally feel the same way about all the interpolated strings. Plain old format("%s", var); works for me.

I use it too, but found it hard to maintain/check ordering and meaning of parameters when you edit the query, add or remove parameters.

It's also non-trivial to implement such functionality, since MS (and Oracle, afaik) require named parameters.

Isn't that a small price to pay to avoid SQL injection attacks? Best, Graham

Yes. Ruby has that to: var = 42 puts "The value of var plus 7 is #{var + 7}" Actually, that's pretty common in scripting languages. Although, I'd be happy at least with a a good string templating lib. Something like: auto str1 = "The value of $name$ is $val$".render( ["name":"myVar", "val":"17"] ); auto str2 = "Alternate delimiters are ::what::".render( ["what":"useful"], "::" ); That'd be more general anyway.

std.conv.text can do this job just fine, bar the "uuu not found" bit. -- = Tomek
