Function execute 

pub fn execute(
    query: &str,
    query_args: Option<&[Arg<'_>]>,
) -> Result<QueryResult>

Execute a one-off query using an in-memory connection.

This function creates a temporary in-memory database connection, executes the query, and returns the result. It’s suitable for queries that don’t require persistent storage.

Arguments

• query - The SQL query string to execute
• query_args - Optional array of query arguments (e.g., output format)

Returns

Returns a QueryResult containing the query output, or an Error if the query fails.

Examples

use chdb_rust::execute;
use chdb_rust::arg::Arg;
use chdb_rust::format::OutputFormat;

// Simple query with default format
let result = execute("SELECT 1 + 1 AS sum", None)?;
println!("{}", result.data_utf8_lossy());

// Query with JSON output format
let result = execute(
    "SELECT 'Hello' AS greeting, 42 AS answer",
    Some(&[Arg::OutputFormat(OutputFormat::JSONEachRow)])
)?;
println!("{}", result.data_utf8_lossy());

Errors

This function will return an error if:

• The query syntax is invalid
• The connection cannot be established
• The query execution fails
