Use when the user needs to write, review, or migrate SQL queries in ADVPL/TLPP using BeginSQL/EndSQL blocks and macro expressions (%table%, %xfilial%, %notDel%, %exp%, %Order%) instead of raw TCQuery string concatenation -- covering INNER/LEFT JOIN patterns, aggregations (SUM/COUNT/GROUP BY/HAVING), subqueries, column type declarations, DML via TCSqlExec, and SQL-injection prevention. Also triggers on Portuguese phrasing like "consulta SQL", "query embutida", "migrar TCQuery para BeginSQL", "escrever SELECT com filial e notDel", or "montar JOIN em ADVPL".

From the source SKILL.md

This skill covers writing SQL inside ADVPL/TLPP using BeginSQL ... EndSQL blocks and their special macro expressions -- %table:TABLE% for physical table resolution, %xfilial:TABLE% for branch filtering, %notDel% for logical-deletion filtering, %exp:EXPRESSION% for safe variable binding, and %Order:TABLE% for primary-key ordering. It also covers column type declarations, JOIN and aggregation patterns, subqueries, and migrating legacy TCQuery string-concatenation code to Embedded SQL.

What this skill does

Embedded SQL is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/embedded-sql/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user needs to write, review, or migrate SQL queries in ADVPL/TLPP using BeginSQL/EndSQL blocks and macro expressions (%table%, %xfilial%, %notDel%, %exp%, %Order%) instead of raw TCQuery string concatenation -- covering INNER/LEFT JOIN patterns, aggregations (SUM/COUNT/GROUP BY/HAVING), subqueries, column type declarations, DML via TCSqlExec, and SQL-injection prevention. Also triggers on Portuguese phrasing like "consulta SQL", "query embutida", "migrar TCQuery para BeginSQL", "escrever SELECT com filial e notDel", or "montar JOIN em ADVPL".
