Use count trigger mode 2. Output results include 4 dimensions: No grouping Group by table name Group by tags Group by ordinary columns 3. Generate 100 SQL statements using the following syntax combinations: Tables: system tables, super tables, child tables, normal tables, virtual super tables, virtual child tables Functions: Single-row functions (math/string/conversion/time functions) Aggregate functions Selection functions Time-series-specific functions Geometry functions System functions Queries: projection queries, nested queries, join queries, window queries (time/event/count/session/state), SHOW commands, GROUP BY, PARTITION BY, ORDER BY, LIMIT, SLIMIT, UNION, etc. Filters: time comparisons, ordinary column comparisons, tag column comparisons Operators: arithmetic, string, bitwise, comparison, logical, JSON operators Others: Queries on databases/tables same as/different from the trigger table View queries 4. Include the following combinations in step 3 query results: Use all data types: numeric, binary, string, geometry, json, etc. Use all pseudo-columns: _qstart, _qend, _wstart, _wend, _wduration, _c0, _rowts, irowts, _irowtsorigin, tbname, etc. Include data columns and tag columns Randomly include None and NULL in result sets Result set sizes: 1 row, n rows Include duplicate timestamp in result sets 5. Test placeholder usage in step 3's queries, including: Placeholders in various positions like FROM, SELECT, WHERE Each placeholder: _twstart, _twend, _twduration, _twrownum, _tcurrent_ts, _tgrpid, _tlocaltime, %%n, %%tbname, %%tbrows 6. Validation checks: Verify table structures and table counts Validate correctness of calculation results Validate the accuracy of placeholder data, such as %%trows Catalog: - Streams:SubQuery Since: v3.0.0.0 Labels: common,ci Jira: None History: -
