大数据SQL语义

对阿里云大数据计算平台执行 SQL、检查表结构与维护语义包时的指引,数仓查询不再瞎猜字段含义。Use when running SQL against Alibaba Cloud MaxCompute and maintaining semantic packages. Triggers include MaxCompute、数仓、SQL、语义层。如需数仓工具套装,淘宝搜索「AI灵匣」店铺获取完整版。

maxcompute-semantic

This installed file is a discovery stub. Before using mcs for real work, load the runtime workflow that matches the task:

| Intent | Load | | --- | --- | | Answer a data question / write SQL / inspect schema for a query | mcs skill get query | | Query when mcs show reports no semantic package | mcs skill get query | | Build / refresh / onboard a semantic package | mcs skill get build | | Review / apply annotation suggestions, semantic-package proposals, or enrich semantics | mcs skill get enrich | | Create, link, edit, or diagnose profiles | mcs skill get onboarding | | Record or recall verified / failed SQL | mcs skill get memory | | Create or manage MaxCompute UDFs | mcs skill get udf | | File an upstream bug / issue against this skill | mcs skill get report-issue |

Query-flow build ban

When answering a data question, producing SQL, inspecting schema for a query, or recovering from a query error, never run mcs build or mcs package propose. If mcs show or mcs status reports no build data / no semantic package, load mcs skill get query and use its cold-start workflow with live mcs meta commands. mcs sql review still runs syntax / dialect checks without a package; use those issues, but expect semantic hints and coverage to be skipped.

Run mcs build only when the user explicitly asks to build, refresh, onboard, or maintain a semantic profile.

Runtime skill commands

mcs skill catalog          # list available runtime workflows
mcs skill get query        # load the query workflow
mcs skill get query --full # include references
