ExecuteNonQuery(String)
¶
Summary
Executes a SQL statement against a connection object.
Remarks
You can use ExecuteNonQuery to perform catalog operations (for example, querying the structure of a database or creating database objects such as tables), or to change the data in a database by executing UPDATE, INSERT, or DELETE statements. Although ExecuteNonQuery does not return any rows, any output parameters or return values mapped to parameters are populated with data. For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.
Return Value
Type | Description |
---|---|
Int32 | The number of rows affected. |
Parameters
Name | Type | Description |
---|---|---|
sqlStatement | String | The sqlStatement to be excuted. |
ExecuteQuery(String)
¶
Summary
Executes the query and returns the result returned by the query.
Remarks
Use the ExcuteScalar method to retrieve a single value from the database. This requires less code than use the ExcuteQuery method and then performing the operations necessary to generate the single value using the data.
Return Value
Type | Description |
---|---|
DataTable | The result set in the format of dataTable. |
Parameters
Name | Type | Description |
---|---|---|
sqlStatement | String | The SQL statement to be excuted. |
ExecuteScalar(String)
¶
Summary
Executes the query and returns the first column of the first row in the result set returned by the query. All other columns and rows are ignored.
Remarks
Use the ExcuteScalar method to retrieve a single value from the database. This requires less code than use the ExcuteQuery method and then performing the operations necessary to generate the single value using the data.
Return Value

---|---|
Object | The first column of the first row in the result set. |
Parameters
Name | Type | Description |
---|---|---|
sqlStatement | String | The SQL statement to be excuted. |
GetAllFeatures(IEnumerable<String>)
¶
Summary
This method returns all of the InternalFeatures in the FeatureSource.
Remarks
This method returns all of the InternalFeatures in the FeatureSource. It will return whatever is returned by the GetAllFeaturesCore method, along with any of the additions or subtractions made if you are in a transaction and that transaction is configured to be live. The main purpose of this method is to be the anchor of all of our default virtual implementations within this class. We as the framework developers wanted to provide you the user with as much default virtual implementation as possible. To do this, we needed a way to get access to all of the features. For example, let's say we want to create a default implementation for finding all of the InternalFeatures in a bounding box. Because this is an abstract class, we do not know the specifics of the underlying data or how its spatial indexes work. What we do know is that if we get all of the records, then we can brute-force the answer. In this way, if you inherited from this class and only implemented this one method, we can provide default implementations for virtually every other API. While this is nice for you the developer if you decide to create your own FeatureSource, it comes with a price: namely, it is very inefficient. In the example we just discussed (about finding all of the InternalFeatures in a bounding box), we would not want to look at every record to fulfil this method. Instead, we would want to override the GetFeaturesInsideBoundingBoxCore and implement specific code that would be faster. For example, in Oracle Spatial there is a specific SQL statement to perform this operation very quickly. The same holds true with other specific FeatureSource examples. Most default implementations in the FeatureSource call the GetFeaturesInsideBoundingBoxCore, which by default calls the GetAllFeaturesCore. It is our advice that if you create your own FeatureSource that you ALWAYS override the GetFeatureInsideBoundingBox. This will ensure that nearly every other API will operate efficiently. Please see the specific API to determine what method it uses. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

GetFeaturesNearestTo(BaseShape,GeographyUnit,Int32,IEnumerable<String>)
¶
Summary
This method returns a user defined number of InternalFeatures that are closest to the TargetShape.
Remarks
This method returns a user defined number of InternalFeatures that are closest to the TargetShape. It is important to note that the TargetShape and the FeatureSource must use the same unit, such as feet or meters. If they do not, then the results will not be predictable or correct. If there is a current transaction and it is marked as live, then the results will include any transaction Feature that applies. The implementation we provided create a small bounding box around the TargetShape and then queries the features inside of it. If we reach the number of items to find, then we measure the returned InternalFeatures to find the nearest. If we do not find enough records, we scale up the bounding box and try again. As you can see, this is not the most efficient method. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesNearestCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

This method returns a user defined number of InternalFeatures that are closest to the TargetShape.
Remarks
This method returns a user defined number of InternalFeatures that are closest to the TargetShape. It is important to note that the TargetShape and the FeatureSource must use the same unit, such as feet or meters. If they do not, then the results will not be predictable or correct. If there is a current transaction and it is marked as live, then the results will include any transaction Feature that applies. The implementation we provided create a small bounding box around the TargetShape and then queries the features inside of it. If we reach the number of items to find, then we measure the returned InternalFeatures to find the nearest. If we do not find enough records, we scale up the bounding box and try again. As you can see, this is not the most efficient method. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesNearestCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs.

GetFeaturesWithinDistanceOf(BaseShape,GeographyUnit,DistanceUnit,Double,IEnumerable<String>)
¶
Summary
This method returns a collection of InternalFeatures that are within a certain distance of the TargetShape.
Remarks
This method returns a collection of InternalFeatures that are within a certain distance of the TargetShape. It is important to note that the TargetShape and the FeatureSource must use the same unit, such as feet or meters. If they do not, then the results will not be predictable or correct. If there is a current transaction and it is marked as live, then the results will include any transaction Feature that applies. The implementation we provided creates a bounding box around the TargetShape using the distance supplied and then queries the features inside of it. This may not be the most efficient method for this operation. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesWithinDistanceOfCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible.

GetFeaturesWithinDistanceOf(Feature,GeographyUnit,DistanceUnit,Double,ReturningColumnsType)
¶
Summary
This method returns a collection of InternalFeatures that are within a certain distance of the TargetFeature.
Remarks
This method returns a collection of InternalFeatures that are within a certain distance of the TargetShape. It is important to note that the TargetShape and the FeatureSource must use the same unit, such as feet or meters. If they do not, then the results will not be predictable or correct. If there is a current transaction and it is marked as live, then the results will include any transaction Feature that applies. The implementation we provided creates a bounding box around the TargetShape using the distance supplied and then queries the features inside of it. This may not be the most efficient method for this operation. If your underlying data provider exposes a more efficient way, we recommend you override the Core version of this method and implement it. The default implementation of GetFeaturesWithinDistanceOfCore uses the GetFeaturesInsideBoundingBoxCore method for speed. We strongly recommend that you provide your own implementation for this method that will be more efficient. When you override the GetFeaturesInsideBoundingBoxCore method, we recommend that you use any spatial indexes you have at your disposal to make this method as fast as possible. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

GetFirstFeaturesWellKnownType()
¶
Summary
This method returns the well known type that represents the first feature from FeatureSource.
Remarks
The default implementation of GetCountCore uses the GetAllRFeaturesCore method to get WellKnownType of the first feature from all features. We strongly recommend that you provide your own implementation for this method that will be more efficient.
