…ueries (#768) Replace strings.containsStr/hasPrefix/hasSuffix with regexp.compile + =~/!~ operators for CONTAINS, NOT_CONTAINS, STARTS_WITH, ENDS_WITH, and LIKE filters. Regex is compiled into a separate variable before from() so InfluxDB can push the filter down to the storage engine. Add container tests for all partial search operators against both InfluxDB 2 and InfluxDB 3. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>
Add (?i) flag to Flux regex patterns and use ILIKE instead of LIKE in SQL queries for CONTAINS, NOT_CONTAINS, STARTS_WITH, ENDS_WITH, and LIKE operators. Add case-insensitive container tests for both engines. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>
…nflux2 (#768) Add new integration tests organized into @nested classes covering filters ($eq, $ne, $or), pagination (limit/offset), and edge cases (empty results, no-match count, expression aliases). Fix InfluxEngine to return a default row with zeros for ungrouped aggregation queries that produce empty results, aligning with SQL-standard behavior and InfluxDB 3.

…r across sub-queries (#768) The aggregation query builder was dropping the preamble (regex variable declarations like _re0 = regexp.compile(...)) when combining sub-queries, causing invalid Flux queries when using partial string filters (starts_with, contains, etc.) with aggregations. Also made the regex counter shared across all sub-queries to avoid variable name collisions. Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>
