NoopQueryRunner

A query runner that simulates a database connection and always returns empty results. Useful for testing or disabling execution without modifying application logic.

Supported databases

• MariaDB
• MySQL
• Oracle
• PostgreSQL
• SQLite
• SQL Server

Tip

NoopQueryRunner supports synchronous query execution. See the Synchronous query runners for more information.

Do not share connections between requests

A ts-sql-query connection object — along with the query runner instances passed to its constructor — represents a dedicated connection to the database.

Therefore, you must not share the same connection object between concurrent HTTP requests. Instead, create a new connection object for each request, along with its own query runners.

Even if the query runner internally uses a connection pool, the ts-sql-query connection still represents a single active connection, acquired from the pool. It must be treated as such and never reused across requests.

Usage Example

import { NoopQueryRunner } from "ts-sql-query/queryRunners/NoopQueryRunner";

async function main() {
    const connection = new DBConnection(new NoopQueryRunner());
    // Queries here will not hit a real database
}
