There is no need to close this tag: it will be directly replaced by the result

Using [lookup] in your template performs an extremely fast search through the specified database and returns either the value of the returnField in the found record, or the literal text of the notFound value. The search is a case-sensitive, exact match, so "Grant" does not equal "grant." If you want more control over the search criteria, use a [search] context instead.

You can specifiy a WebDNA table, in place of a db file.For example: [Lookup table=TableName&...].



[lookup] is about 40 times faster than [search]. Using several [lookup] to recover data from your bases might be faster than a single [search]
