Quick start

from exonware.xwquery import XWQuery

data = {'users': [
    {'name': 'Alice', 'age': 30, 'city': 'NYC'},
    {'name': 'Bob', 'age': 25, 'city': 'LA'},
    {'name': 'Charlie', 'age': 35, 'city': 'NYC'},
]}

result = XWQuery.execute("""
    SELECT name, age
    FROM users
    WHERE age > 25 AND city = 'NYC'
""", data)
# result.data → [{'name': 'Alice', 'age': 30}, {'name': 'Charlie', 'age': 35}]

Convert between formats: XWQuery.convert(sql_string, from_format='sql', to_format='graphql').
Parse only: XWQuery.parse("SELECT * FROM users", source_format='sql').

What you get

Area	Description
Execution	Run queries on any Python data (node or table). Parse → plan → execute; one engine, one contract.
Grammars	35+ formats (SQL, GraphQL, Cypher, SPARQL, MQL, PromQL, JQ, JMESPath, …) via xwsyntax. Parse, generate, validate.
Operations	CRUD, filtering, aggregation, graph (MATCH, PATH), JOIN, UNION, WINDOW, PIPE, and more.
Integration	Consumed by xwstorage, xwaction, xwbase. One universal script (XWQS); zone execution (e.g. S3) converts to XWQS first.

Current phase: Alpha. Executor refactor and doc alignment in progress. Status: REF_22_PROJECT.
