@debugr/sql-common v3.0.0-rc.6

Common SQL interfaces and utilities

This package defines the shape of the data included in entries which represent an SQL query. Plugins which produce or consume such entries should conform to this shape. Unless you're developing a Debugr plugin or log handler, you usually don't need to worry about this package, as it will be installed and used automatically when required.

For plugin developers

The package exports the following type definitions:

export interface SqlQueryData {
  query: string;         // The SQL query
  parameters?: any[];    // Any parameters passed to the SQL query
  error?: string;        // Any error message produced by the query
  stack?: string;        // Stack trace for the call which issued a query
  affectedRows?: number; // The number of rows affected by a DML query
  rows?: number;         // The number of rows selected by a DQL query
  time?: number;         // The time the query took to execute
}

export interface SqlQueryLogEntry<
  TTaskContext extends TContextBase = TContextBase,
  TGlobalContext extends TContextShape = TContextShape,
  > extends LogEntry<TTaskContext, TGlobalContext> {
  type: 'sql.query';
  data: SqlQueryData;
}

There are also a couple of utility functions exported:

• formatQueryTime(ms: number, html: boolean = false): string - This function formats the duration of an SQL query as a fraction of seconds if the duration was over 1000ms, or as milliseconds if the duration was lower, with the numeric part optionally wrapped in a HTML <strong> tag when html is set to true. For example: 35.753241 would result in 35.75 ms or <strong>35.75</strong> ms and 5645.6768576 would result in 5.64 s or <strong>5.64</strong> s.
• createQueryFormatter(): (query: string) => string - This function attempts to load the @sqltools/formatter package and returns a preconfigured callback which converts reserved words to uppercase and inserts some strategic newlines to make the query easier to read; if the package isn't installed, it simply returns a noop callback which just returns the passed query as-is.
