FTS5 virtual table
Learn FTS5 virtual table in SQLite through the exact construct, a dedicated example, a boundary case, and a mastery check.
FTS5 virtual table is an atomic SQLite lesson inside Advanced SQLite. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.
Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on FTS5 virtual table rather than on generic SQLite syntax.
Topic-specific example
CREATE VIRTUAL TABLE docs USING fts5(title,body);
SELECT rowid,title FROM docs WHERE docs MATCH 'sqlite';
Test FTS5 virtual table with an empty result, NULL/missing value, duplicate key, or concurrent operation where relevant; database behavior should be verified at the boundary shown by this example.
