Adopted by several works later on (Miller et al., 1996;Zettlemoyer and Collins, 2009;Suhr et al., 2018), ATIS has only a single domain for flight planning which limits the possible SQL logic it contains.
to ATIS, SParC consists of a large number of complex SQL queries (with most SQL syntax components) inquiring 200 databases in 138 different domains, which contributes to its diversity in query semantics and contextual dependencies.
