| Name | Description |
| AutoCache | Automatically caches the results of SELECT queries into a cache database specified by either CacheLocation or both of CacheConnection and CacheProvider . |
| CacheConnection | The connection string for the cache database. This property is always used in conjunction with CacheProvider . Setting both properties will override the value set for CacheLocation for caching data. |
| CacheLocation | Specifies the path to the cache when caching to a file. |
| CacheMetadata | This property determines whether or not to cache the table metadata to a file store. |
| CacheProvider | The name of the provider to be used to cache data. |
| CacheTolerance | The tolerance for stale data in the cache specified in seconds when using AutoCache . |
| ConnectionLifeTime | The maximum lifetime of a connection in seconds. Once the time has elapsed, the connection object is disposed. |
| FileRetrievalDepth | Specify the depth level of folders you want to query from the Root table. |
| FirewallPassword | A password used to authenticate to a proxy-based firewall. |
| FirewallPort | The TCP port for a proxy-based firewall. |
| FirewallServer | The name or IP address of a proxy-based firewall. |
| FirewallType | The protocol used by a proxy-based firewall. |
| FirewallUser | The user name to use to authenticate with a proxy-based firewall. |
| Location | A path to the directory that contains the schema files defining tables, views, and stored procedures. |
| Logfile | A path to the log file. |
| MaxLogFileCount | A string specifying the maximum file count of log files. When the limit is hit, a new log is created in the same folder with the date and time appended to the end and the oldest log file will be deleted. |

| MaxRows | Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time. |
| Offline | Use offline mode to get the data from the cache instead of the live source. |
