Question 1

How do I query nested JSON objects with jsonql?

Accepted Answer

jsonql supports dot notation for accessing nested fields, but the README doesn't explicitly demonstrate it. You'll need to refer to the linked gojq documentation for detailed syntax on navigating complex JSON structures, as the library builds on that foundation.

Question 2

jsonql vs jq for Go projects?

Accepted Answer

jsonql is a Go library with SQL-like syntax ideal for embedding in applications, while jq is a command-line tool with a more powerful but different query language. Choose jsonql for simplicity in Go code, but jq if you need richer features or cross-platform usage.

Question 3

Can jsonql handle arrays of objects efficiently?

Accepted Answer

Yes, it can query arrays of objects using operators like contains for array values and standard comparisons, as shown in the example JSON array. However, performance may degrade with large arrays due to linear scanning without indexes.

Question 4

How to install jsonql in a Go project?

Accepted Answer

Use go get -u github.com/elgs/jsonql, as per the README. Then import the package and create a parser instance with NewStringQuery or similar methods to start querying your JSON data directly in code.

Question 5

Does jsonql support case-insensitive regex matching?

Accepted Answer

The README shows ~= for regex matching but doesn't specify case sensitivity. You likely need to use standard regex patterns within the query string, such as name ~= '(?i)e.*' for case-insensitive matches, and check the gojq docs for confirmation.

Question 6

What error handling does jsonql provide?

Accepted Answer

Errors are returned from the Query method, as seen in examples where err is checked. Handle parsing errors for invalid JSON or malformed queries, but note that the library offers limited diagnostic details for query failures.
