About embedded-sql
A skill for developers writing, reviewing, or modernizing SQL in ADVPL/TLPP. It explains `BeginSQL` macros, query patterns, safety constraints, and when to use `TCSqlExec` for data changes.
Key features
- 01`BeginSQL` syntax and macros
- 02JOIN, aggregation, and subquery patterns
- 03Safe variable binding and row filters
- 04Migration from concatenated `TCQuery` SQL
- 05DML guidance with `TCSqlExec`
Use cases
- 01Writing a new ADVPL/TLPP query
- 02Reviewing SQL for safety and correctness
- 03Converting legacy `TCQuery` strings
- 04Choosing an approach for INSERT, UPDATE, or DELETE

Details
From the project READMEEmbedded SQL in ADVPL/TLPP
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.
Activate this skill whenever the user is writing a new query, reviewing an existing one for correctness/safety, or converting old concatenated-string SQL to the modern BeginSQL syntax. It also covers the restrictions and gotchas of BeginSQL (no * at line start, always include %notDel% and filial filtering, use GetNextAlias(), close aliases) and when to use TCSqlExec instead for INSERT/UPDATE/DELETE.
It does not cover general native function lookups unrelated to SQL (see protheus-reference), business-process context for which tables/fields to query (see protheus-business), or generating documentation for a routine that happens to contain SQL (see documentation-patterns).
