SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill enables building complex, dynamic query filters for BKND data operations, empowering developers to express advanced criteria succinctly and correctly.

Core Features & Use Cases

Operator coverage: supports all filter operators ($eq, $ne, $gt, $lt, $like, $ilike, $in, $nin, $isnull, $between) for precise comparisons.
Logical grouping: supports $or and $and combinations for complex decision trees, including cross-entity joins.
Dynamic query building: enables programmatic construction of WHERE clauses and join-based filters for data-rich applications.

Quick Start

Example: build a filter to retrieve posts with status 'published' and category 'news' using a join on author.

FAQPage Schema

How do I build dynamic query filters with multiple operators in BKND?▼

Dynamic query filters in BKND are built using operators like $eq, $ne, $gt, $lt, $like, $ilike, $in, $nin, $isnull, and $between to construct precise comparison conditions for data operations. Logical groupings with $and and $or allow composing complex WHERE clauses.

Can I combine AND and OR conditions when filtering related fields via joins in BKND?▼

Yes, combining AND and OR conditions for joined entities is supported in BKND. You can group criteria using $and and $or operators to create complex decision trees, enabling cross-entity joins to filter records by related fields across multiple connected collections.

What is the best way to use $like and $ilike operators for pattern matching in BKND queries?▼

The $like and $ilike operators in BKND queries enable pattern matching for string values, with $ilike providing case-insensitive matching. These operators are applied within filter objects to retrieve records where specific fields match desired textual patterns.

Does BKND support filtering by a list of values or checking for null fields?▼

BKND supports filtering by value lists using the $in and $nin operators, and checks for null fields using the $isnull operator. This allows queries to include or exclude records matching any value within a specified array or identify missing data.

How do I filter records within a specific range using BKND query operators?▼

To filter records within a specific range in BKND, use the $between operator. This operator allows queries to match values that fall inside a defined minimum and maximum boundary, useful for numerical or date-based data retrieval.

Why are my dynamic readMany queries not returning expected results with complex filters?▼

Complex dynamic readMany queries may fail if filter operators are incorrectly nested or if logical groupings like $and and $or are improperly structured. Ensure all operator conditions and joined entity filters are correctly composed within the WHERE clause.
