Detailed Description
Geodatabase is used to open and access the contents of a mobile geodatabase (.geodatabase file) that can contain geographic features, non-spatial tabular data, and data such as attachments, utility networks, field domain definitions, contingent values, and relationships between layers/tables. A geodatabase is typically an offline copy of data from an ArcGIS service, although it can be created using ArcMap or ArcGIS Pro. The geodatabase contains a number of GeodatabaseFeatureTables. Each GeodatabaseFeatureTable contains attribute data. For spatial features, it also stores the geometry and rendering information. A GeodatabaseFeatureTable can be used to create a feature layer to display on a map.
Geodatabases can contain one or more geodatabase feature tables. You can create a layer from a GeodatabaseFeatureTable tables, as follows:
- A FeatureLayer from any table returned by geodatabaseFeatureTables that contains point, polyline, or polygon features. Check that FeatureTable::hasGeometry is
true. - An AnnotationLayer from any table returned by geodatabaseAnnotationTables.
- A DimensionLayer from any table returned by geodatabaseDimensionTables.
You can generate a mobile geodatabase file from an ArcGIS feature service and downloaded it to a device using offline workflows offered by the GeodatabaseSyncTask and the OfflineMapTask. Apps can then operate offline to view and edit the features in these geodatabases. If the geodatabases are enabled for synchronization with the original feature service, edits can be synchronized when connectivity is restored.
Mobile geodatabase files can also be created with ArcGIS Pro. These geodatabases can be used offline but they do not support synchronization with the original feature service. See Build offline applications for more information.
Geodatabase adopts the loadable pattern; the geodatabase feature tables can be accessed after loaded. See Loadable for more information. By default, the Geodatabase type is automatically loaded after instantiated if a path to a geodatabase file was supplied. You can change this default behavior by declaring the autoLoad property as false.
Both the geodatabaseFeatureTablesByTableName and geodatabaseFeatureTablesByLayerId properties may be used with property binding. They are both updated when the Geodatabase has loaded.
// Display a feature layer with a Geodatabase FeatureLayer { id: gdbFeatureLayer visible: false featureTable: geodatabase.geodatabaseFeatureTablesByTableName["Trailheads"] ?? null Geodatabase { id: geodatabase path: dataPath + "geodatabase/LA_Trails.geodatabase" } }
See also Loadable and GeodatabaseFeatureTable.
Property Documentation
autoLoad : bool |
Determines if this Geodatabase instance should attempt to automatically load after it has instantiated.
By default this property is true which means a Geodatabase will attempt to load if it has a path to a mobile geodatabase file. It may be useful to declare this property as false in the case you would like to delay the loading of the Geodatabase to be controlled manually at a later time.
This property cannot be set after the Geodatabase has instantiated.

[read-only] geodatabaseFeatureTablesByTableName : jsobject |
Returns a map of geodatabase feature tables with the table name as the key (read-only).
This property is populated after the geodatabase loads.
[read-only] hasLocalEdits : bool |
Returns true if the geodatabase has local edits, false otherwise.
If the geodatabase was created by ArcGIS Pro, this method returns false because there is no concept of uploading or applying edits. If you want to determine which tables have local edits, examine GeodatabaseFeatureTable::hasLocalEditsSince(date).
See also GeodatabaseSyncTask and OfflineMapTask.
[read-only, since Esri.ArcGISRuntime 100.3] inTransaction : bool |
Returns true if a transaction is active on the geodatabase, false otherwise (read-only).
A transaction manages a series of geodatabase edits as a single unit of work. You can start a transaction by calling beginTransaction. All edits made after this call are part of the transaction.
A geodatabase transaction stays active until you end it by calling commitTransaction or rollbackTransaction. commitTransaction saves all edits in the transaction to the geodatabase and ends the transaction. rollbackTransaction discards all edits in the transaction and ends the transaction.
If the app unexpectedly disconnects from the database, any active transaction will be rolled back. If the app crashes, or the user closes the app without saving edits, the transaction will be rolled back and the edits discarded.
This property was introduced in Esri.ArcGISRuntime 100.3.
See also beginTransaction, rollbackTransaction, and commitTransaction.
[read-only] loadError : Error |
Returns the load error (read-only).
Note: load errors are also reported on the error property and emit the errorChanged signal.
See also Loadable.
[read-only] loadStatus : Enums.LoadStatus |
Returns the load status code of this Loadable object (read-only).
See also Enums.LoadStatus and Loadable.
[read-only, since Esri.ArcGISRuntime 100.6] minServerGeneration : string |
The minimum server generation number for the geodatabase (read-only).
Server generation numbers indicate the state of a geodatabase or individual layers with respect to changes which have been synced with the online service. The number increases as new changes from the online feature service are synced to the local geodatabase.
If the syncModel is Enums.SyncModelGeodatabase, the value will indicate the server generation number for the entire geodatabase. If the syncModel is Enums.SyncModelLayer, the value will be the lowest server generation number for all of the layers in the geodatabase. This property will be -1 if the geodatabase does not support sync (Enums.SyncModelNone).
This property will be -1 until the geodatabase is Enums.LoadStatusLoaded.
Note that this property is only required when using advanced workflows to manually apply pre-generated changes and not when performing a sync directly against the online service.
Note: The underlying property is represented as a 64-bit integer type. See Accessing 64-bit integer properties from QML.
This property was introduced in Esri.ArcGISRuntime 100.6.
See also minServerGenerationAsInt.
[read-only, since Esri.ArcGISRuntime 100.6] minServerGenerationAsInt : double |
The same as minServerGeneration but represented as an integer type (read-only).
Note: The underlying property is represented as a 64-bit integer type. See Accessing 64-bit integer properties from QML.
This property was introduced in Esri.ArcGISRuntime 100.6.
path : url |
The path to the mobile geodatabase file.
If the specified path points to a stand-alone mobile geodatabase created with ArcGIS Pro and contains a controller dataset, such as a utility network or parcel fabric, the feature tables on this geodatabase are read-only. The presence of utility networks can be checked using Geodatabase::utilityNetworks. Constructing a geodatabase from a path to a geodatabase file does not automatically load the geodatabase. You must load it explicitly.
You cannot set the path to the geodatabase after the instance is already loaded.
[read-only] serviceUrl : url |
Returns the URL of the service that was the source of this geodatabase (read-only).
This property is populated after the geodatabase loads.
[read-only] syncEnabled : bool |
Returns whether sync is enabled for the geodatabase (read-only).
This property is populated after the geodatabase loads.
[read-only, since Esri.ArcGISRuntime 100.2] syncId : string |
Returns the sync ID of the geodatabase (read-only).
Sync ID is available if syncEnabled is true. The sync ID is the same as the replica ID described in the REST documentation. It is used by the geodatabase service to uniquely identify when carrying out sync operations. It is also used to unregister the geodatabase using the GeodatabaseSyncTask.unregisterGeodatabaseAsync(GUID).
Note: The returned string will be empty if there is an error or if this is not a sync-enabled geodatabase or the geodatabase is not loaded.
This property was introduced in Esri.ArcGISRuntime 100.2.
See also GeodatabaseSyncTask.
[read-only] syncModel : Enums.SyncModel |
Returns the sync model defining how datasets within the geodatabase are synchronized with the originating ArcGIS feature service (read-only).
Sync model only applies to the geodatabase if syncEnabled is true.
This property is populated after the geodatabase loads.
See also Enums.SyncModel.
[read-only, since Esri.ArcGISRuntime 100.11] utilityNetworks : list<UtilityNetwork> |
The list of UtilityNetwork objects that are packaged within the Geodatabase (read-only).
The returned list will be empty if the geodatabase itself is not loaded or if no utility networks exist in the geodatabase.
This property was introduced in Esri.ArcGISRuntime 100.11.

Method Documentation
|
Starts a transaction on the geodatabase.
This method starts a new transaction on the geodatabase. The transaction fails to begin if another transaction is already active. A geodatabase cannot be synchronized while a transaction is active.
Transactions must be started and stopped on a single thread of execution. This method should only be called once per transaction. Repeatedly calling this method from the same thread will raise an error.
This method was introduced in Esri.ArcGISRuntime 100.3.
void cancelLoad() |
See also Loadable.
|
Cancel the task with the ID taskId.
Returns false if the task cannot be canceled or there is no task with the specified id taskId.
This method was introduced in Esri.ArcGISRuntime 100.14.
See also Cancelable.
|
Closes the Geodatabase by forcefully removing all internal references to it.
This is to allow for deleting a Geodatabase when you're done using it. That can be problematic in some workflows since there can be outstanding references to it and it may be difficult to track and delete them all.
You should stop using the geodatabase before you close it. For example, you should terminate geodatabase synchronization, remove feature layers from maps, and release the feature tables. Any attempt to access the geodatabase after it is closed will fail, resulting in an error. After closing a geodatabase, you can delete the geodatabase file from the device.
This method is not needed for typical workflows.
The close method has no effect on the loadStatus of the Geodatabase. Once closed, the object cannot be reloaded or used again and the loadStatus is no longer indicative of the state.
Warning: Once close is called the Geodatabase object is in an undefined state and should no longer be used.
This method was introduced in Esri.ArcGISRuntime 100.1.
|
Commits the current transaction on the geodatabase.
Commits the edits in the current transaction to the geodatabase. This will also end the transaction. An error will be thrown if a transaction has not been started on the geodatabase. Transactions must be started and stopped on a single thread of execution.
This method was introduced in Esri.ArcGISRuntime 100.3.
|
Creates a new domain in the geodatabase.
- domainDescription - The description of the domain to create.
Creating domains is only supported in mobile geodatabases (either created in Pro or via create(string)). The domain name must not already exist in the geodatabase.
Returns a string representing the task ID of the asynchronous task.
This method was introduced in Esri.ArcGISRuntime 100.14.
|
Creates a new table in the geodatabase.
- tableDescription - The description of the table to create.
Creating tables is only supported in mobile geodatabases (either created in Pro or via create(string)). The table name must not already exist in the geodatabase. For additional table name constraints, see TableDescription::tableName. Returns a string representing the task ID of the asynchronous task.
This method was introduced in Esri.ArcGISRuntime 100.14.
|
Deletes the domain with the specified name from the geodatabase.
- domainName - The name of the domain to delete.
Deleting domains is only supported in mobile geodatabases (either created in Pro or via create(string)). The domain with the specified name must exist in the geodatabase. The domain must not be in use by any fields in existing tables.
Returns a string representing the task ID of the asynchronous task.
This method was introduced in Esri.ArcGISRuntime 100.14.
|
Deletes an existing table from the geodatabase.
- tableName - The name of the table to delete.
Deleting tables is only supported in mobile geodatabases in Pro or using create(string)). Attempting further use of a deleted table, such as rendering it in a feature layer or querying it, may result in errors.
Returns a string representing the task ID of the asynchronous task.
This method was introduced in Esri.ArcGISRuntime 100.14.
void load() |
See also Loadable.
void retryLoad() |
See also Loadable.
|
Rollback the edits in the transaction from the geodatabase.
Discards the edits in the current transaction from the geodatabase. This will also end the transaction. An error will be thrown if a transaction has not been started on the geodatabase. Transactions must be started and stopped on a single thread of execution.
This method was introduced in Esri.ArcGISRuntime 100.3.
|
Returns a UtilityNetwork from the geodatabase with the specified utility network name.
- utilityNetworkName - The name of the utility network.
This method was introduced in Esri.ArcGISRuntime 100.11.
