BQL is a SQL-like query language specifically designed for the Bullet query engine, which provides an easy-to-use yet powerful interactive SQL-like interface.
This project contains a BQL parser built in ANTLR 4. A BQL query will be parsed, classified, validated and extracted to a Bullet Query.
Bullet-BQL is created to provide users with a friendly SQL-like layer to manipulate the power of Bullet query engine.
-
The Bullet-BQL artifact can be obtained from JCenter.
-
To run the tool from the command line, first compile:
mvn clean compileThen you can use bullet-bql to parse BQL strings into Bullet JSON queries. To run:
mvn exec:java -
Bullet-BQL is currently being integrated into Bullet-Service, and will provide a BQL endpoint directly.
-
Build a Bullet Query from a BQL string.
Simply construct a
BulletQueryBuilderand callbuildQuery(String bql). A Bullet Query is returned. -
You can change the max query length in
BQLConfigby altering the.yaml.
