For text-to-SQL generation, several SQLspecific approaches have been proposed (Zhong et al., 2017;Xu et al., 2017;Huang et al., 2018;Yu et al., 2018a;Dong and Lapata, 2018;Yavuz et al., 2018) based on WikiSQL dataset (Zhong et al., 2017).
all of them are limited to the specific WikiSQL SQL sketch, which only supports very simple queries.
