Directly executing SQL may lead to unexpected results, corrupted data, security vulnerabilities and other issues. **Signature:** ```typescript execute(command: Command, parameters?: NamedParameters | PositionalParameters, options?: Options): Promise<AnyObject>; ``` ## Parameters <table><thead><tr><th> Parameter </th><th> Type </th><th> Description </th></tr></thead> <tbody><tr><td markdown="1"> command </td><td markdown="1"> Command </td><td markdown="1"> A parameterized SQL command or query. </td></tr> <tr><td markdown="1"> parameters </td><td markdown="1"> NamedParameters \| PositionalParameters </td><td markdown="1"> _(Optional)_ List of parameter values to use. </td></tr> <tr><td markdown="1"> options </td><td markdown="1"> Options </td><td markdown="1"> _(Optional)_ Additional options, for example `transaction`. </td></tr> </tbody></table> **Returns:** Promise<AnyObject> A promise which resolves to the command output. The output type (data structure) is database specific and often depends on the command executed. ## Example ```ts // MySQL const result = await db.execute( 'SELECT * FROM Products WHERE size > ?', [42] ); // PostgreSQL const result = await db.execute( 'SELECT * FROM Products WHERE size > $1', [42] ); ```
