### setCommand(string) {#setCommand-string-}

The string containing the database command to pass to the data provider API that will interact with the external source in order to retrieve data

```javascript
setCommand(value: string) : void;
```

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | string | The value to set. |

### getCommandType() {#getCommandType--}

Returns [OLEDBCommandType](../oledbcommandtype/) type.

```


### getSecondCommand() {#getSecondCommand--}

Specifies a second command text string that is persisted when PivotTable server-based page fields are in use. For ODBC connections, serverCommand is usually a broader query than command (no WHERE clause is present in the former). Based on these 2 commands(Command and ServerCommand), parameter UI can be populated and parameterized queries can be constructed

```javascript
getSecondCommand() : string;
```


### setSecondCommand(string) {#setSecondCommand-string-}

For ODBC connections, serverCommand is usually a broader query than command (no WHERE clause is present in the former). Based on these 2 commands(Command and ServerCommand), parameter UI can be populated and parameterized queries can be constructed

```javascript
