Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection settings for this provider.
| Property | Description |
| BatchSize | The maximum size of each batch operation to submit. |
| BuiltInColumnMapping | A list of column name mappings for MongoDB's built-in columns. |
| DataModel | By default, the provider will not automatically discover the metadata for a child table as its own distinct table. To enable this functionality, set DataModel to Relational . |
| DefaultDomain | This property is used for the Oracle Database Gateway for ODBC. |
| EnableForeignKeyDetection | Whether to detect the foreign keys in ODBC. |
| FlattenArrays | By default, nested arrays are returned as strings of JSON. The FlattenArrays property can be used to flatten the elements of nested arrays into columns of their own. Set FlattenArrays to the number of elements you want to return from nested arrays. |
| FlattenObjects | Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON. |
| GenerateSchemaFiles | Indicates the user preference as to when schemas should be generated and saved. |
| IncludeDualTable | Set this property to mock the Oracle DUAL table for better compatibility with Oracle database. |
| LimitKeySize | The maximum length of a primary key column. |
| MapBigintToVarchar | This property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default. |
| MapToInt | This property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default. |
| MapToLongVarchar | This property controls whether or not a column is returned as SQL_LONGVARCHAR. |
| MapToWVarchar | This property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default. |
| MaximumColumnSize | The maximum column size. |
| MaxRows | Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses. |
| NoCursorTimeout | The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that. |
| Other | These hidden properties are used only in specific use cases. |
| Pagesize | The maximum number of results to return per page from MongoDB. |
| PseudoColumns | Specify a set of pseudocolumns to expose as columns. |
| QueryPassthrough | This option passes the query to MongoDB as-is. |
| Readonly | You can use this property to enforce read-only access to MongoDB from the provider. |
| ReadPreference | Set this to a strategy for reading from a replica set. Accepted values are primary, primaryPreferred, secondary, secondaryPreferred, and nearest. |
| ReadPreferenceTags | Use this property to target a replica set member or members that are associated with tags. |
| RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
| RTK | The runtime key used for licensing. |
| ServiceKind | Specify the kind of service. |
| SlaveOK | This property sets whether the provider is allowed to read from secondary (slave) servers. |
| Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
| TypeDetectionScheme | Comma-separated options for how the provider will scan the data to determine the fields and datatypes in each document collection. |
| UpdateScheme | Sets replacing or merging target document with updating fields is performed by executing update statement. |
| UpperCaseIdentifiers | This property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway. |
| UseFindAPI | Execute MongoDB queries using db.collection.find(). |
| UserDefinedViews | A filepath pointing to the JSON configuration file containing your custom views. |
| WriteConcern | Requests acknowledgment that the write operation has propagated to the specified number of mongod instances. |
| WriteConcernJournaled | Requires acknowledgment that the mongod instances, as specified in the WriteConcern property, have written to the on-disk journal. |
| WriteConcernTimeout | This option specifies a time limit, in milliseconds, for the write concern. |
| WriteScheme | Sets whether the object type for inserted or updated objects is determined from the existing column metadata or the input value type. |
