Addressing the mismatch between natural language descriptions and the corresponding SQL queries is a key challenge for text-to-SQL translation. To bridge this gap, we propose an SQL intermediate representation (IR) called Natural SQL (NatSQL). Specif
ically, NatSQL preserves the core functionalities of SQL, while it simplifies the queries as follows: (1) dispensing with operators and keywords such as GROUP BY, HAVING, FROM, JOIN ON, which are usually hard to find counterparts in the text descriptions; (2) removing the need of nested subqueries and set operators; and (3) making the schema linking easier by reducing the required number of schema items. On Spider, a challenging text-to-SQL benchmark that contains complex and nested SQL queries, we demonstrate that NatSQL outperforms other IRs, and significantly improves the performance of several previous SOTA models. Furthermore, for existing models that do not support executable SQL generation, NatSQL easily enables them to generate executable SQL queries, and achieves the new state-of-the-art execution accuracy.
the aim of the research was to use different types of
flour in terms of extraction rates (70-80-90%) and then study the
specifications of these types of flour and the specifications of the dough
and bread produced.
The research aims to study the determinants of purchase to the consumers of chicken
meat in the province of Latakia, and see how it affected the consumer when making a
purchase decision, respondents were surveyed (500) the consumer, was the distrib
ution of
a questionnaire allocated for this purpose.
Use the statistical and analytical method for the study and analysis of the data, which
used randomized complete block design, and testing of F in accordance with the SPSS
statistical program, the research found a range of results, including:
• purchasing decision influenced by a variety of factors: the level of consumer
income - Product Specifications - the price of chicken meat - other meat prices - the views
of friends.
• Low impact of consumer life and the views of the seller and the Declaration on the
purchase decision process.
This research is aimed to verify the statement of pavement structural design and construction of bituminous concrete mixture which is used on wearing layers in roads and highways in Damascus city.
It's clearly found that many of these bituminous con
crete mixtures were far - away from standards and specifications regards to flexible pavements such as aggregate gradations, Marshall Stability, bitumen content and Marshall flow. The role of highway statements authorities who deal with pavement
design and supervise the construction is quit necessity.
Finally test results of cores taken from several roads in Damascus city were analyzed and compared with the designed mix «original» test results which was done in Damascus University labs.
