public class Table
Esri Table object.
A Table object has one or more columns, referred to as fields, and contains an unordered collection of rows. Each row has for each field exactly one value in the data type of the field.
A Table is a Dataset and properties such as the name of the table, the persistable name object for the table, and the workspace containing the table, may be obtained via the IDataset interface. In relational terms, a Table object represents an RDBMS table or view. In objected-oriented terms, a Table object represents an ObjectClass or a RelationshipClass in a geodatabase. A Table object hands out Row objects which themselves support application callable methods depending on the type of data stored in the table.
The Name property of a Table, accessible via the IDataset interface, returns its fully qualified name. The level of qualification may vary depending on the host DBMS. For example, a table named ‘pipes’, owned by a user named ‘gas’ may be called ‘pipes’ in and Access or File Geodatabase, ‘gas.pipes’ on Oracle and ‘mydb.gas.pipes’ on SQLServer. The ParseTableNamemethod on the ISqlSyntax interface supported by the table’s workspace can be used to split the fully qualified name into its components.

public IRow createRow()
throws IOException,
AutomationException
The CreateRow method creates a new row in the underlying database with a system assigned object id value. A row object representing the created row is returned to the caller. The row object returned has the system assigned object ID as the value of the OIDField. All other fields are initialized to null values if they can be made null and to built-in default values appropriate to the type of the field if they cannot be made null.
The caller is responsible for setting the desired field values into the row and calling the Store method on the row. If the table represents an object class with subtypes, then it is the caller’s responsibility to set the default subtype code into the row and call the InitDefaultValues method on the row before storing, if that is the desired result. For tables without object behavior, insert cursors offer a more efficient way for inserting new rows.
createRow in interface ITableIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IRow getRow(int oID)
throws IOException,
AutomationException
The GetRow method returns an existing row object, given its object ID value. The caller can query the returned row object for additional object specific interfaces. The retrieved row may be modified; calling Store on the row object after changing it will trigger messages to related objects and will mark the row for committing to the database.

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ICursor getRows(Object oids,
boolean recycling)
throws IOException,
AutomationException
The GetRows method returns a cursor that may be used to retrieve a set of rows specified by the input array of object id values. See the description of the Search method to understand the meaning of the recycling parameter. It is far more efficient to retrieve a set of rows using the GetRows method than it is to retrieve each individual row using the GetRow method. The retrieved rows may be modified; Store should be called on the row objects after changing them.
The oids parameter should be passed an integer array. For example:
// Get a recycling cursor for the OID array.
int[] oids = new int[] { 10844, 10853, 10871 };
ICursor cursor = table.getRows(oids, true);

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IRowBuffer createRowBuffer()
throws IOException,
AutomationException
The CreateRowBuffer method creates a new row buffer object in memory and returns it to the caller. No row is created in the database. The returned row buffer does not have an object ID value. The caller can set values into the row buffer and use it as an argument to the InsertRow method on an insert cursor; the latter is obtained by calling the Insert method on the Table.
createRowBuffer in interface ITableIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public void updateSearchedRows(IQueryFilter queryFilter,
IRowBuffer buffer)
throws IOException,
AutomationException
This method will edit the rows matching the query filter's constraints. The values in each row will be replaced with the corresponding field's value in the provided row buffer. The fields being edited should be specified in the query filter's SubFields property. If the row buffer contains null values, and the SubFields property is not properly set, the row's values will be overwritten with the row buffer's null values.

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ICursor update(IQueryFilter queryFilter,
boolean recycling)
throws IOException,
AutomationException
The Update method returns an update cursor that can be used to update or delete rows. It offers somewhat faster performance than multiple calls to Store or Delete on row objects fetched using a non-recycling search cursor for tables storing simple rows and simple features. There is no difference in performance for complex objects and features.
When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ICursor insert(boolean useBuffering)
throws IOException,
AutomationException
The Insert method returns an insert cursor that can be used to bulk insert rows. It offers significantly faster performance than multiple calls to CreateRow and Store for tables storing simple rows and simple features (that is, for tables whose CLSID is esriGeoDatabase.Row, esriGeoDatabase.Object, or esriGeoDatabase.Feature).
Insert cursors on tables containing complex objects use the CreateRow and Store methods to achieve polymorphism, and there is no difference in performance in these cases.
When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.
insert in interface ITableuseBuffering - The useBuffering (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ISelectionSet select(IQueryFilter queryFilter,
int selType,
int selOption,
IWorkspace selectionContainer)
throws IOException,
AutomationException
The Select method returns a selection set that holds either row IDs or row objects from the Table depending on the selection option. Multiple selection sets can be created on the same table. It is up to a client application or object to keep a reference on created selections and use them as appropriate. For example, a FeatureLayer creates and uses selections on a FeatureClass (a type of Table).
The selType parameter determines the type of selection set that will be created: an ID set, a snapshot, or a hybrid. See the ISelectionSet interface for a comparison of the three types.
When calling Select the selectionContainer parameter is no longer required. A null value should be passed as this parameter.

public void addField(IField field)
throws IOException,
AutomationException
Prior to adding a new field to a class, an exclusive schema lock should be obtained using the ISchemaLock interface.
Attempting to add a new field that does not allow null values will fail, if the class already has data in it. The only solution is to recreate the class with the non-nullable field, then copy the rows from the original class into the new class.

public String getCategory()
throws IOException,
AutomationException
IDataset::Category returns a description of the category of the dataset. The description returned from the Category property is the same value that is displayed in the Type column within the Contents tab in ArcCatalog. The value will contain a description of the dataset such as "Topology" prefixed with a description of the type of workspace containing the dataset such as "File Geodatabase".
The description returned from IDataset::Category may change between releases of ArcGIS. In addition to this, returned strings are localized, meaning that code relying on a specific string being provided may fail when deployed with a different version of ArcGIS than it was developed with, or when deployed to a client using a different language than it was developed with.

public IPropertySet getPropertySet()
throws IOException,
AutomationException
The PropertySet property is used to return any additional intrinsic properties (but not metadata properties) that may apply to the dataset. One use of this property is to distinguish between the types of File Geodatabase datafile formats. If called on a Feature Class or Table in a File Geodatabase the Datafile Format property can either be esriFGDBStandardDatafile or esriFGDBCompressedDatafile.
Most datasets do not implement this property and will either raise an error or return a null value if it's called. There are a handful of exceptions that will return property sets; these include the datasets from file geodatabases (as mentioned above) and coverages.
Examples of intrinsic properties for which explicit methods exist include the SpatialReference and the Extent methods available on the IGeoDataset interface. In most cases this PropertySet will be empty.
IDataset::PropertySet is not supported for Graph objects such as a Geometric Network.
getPropertySet in interface IDatasetIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public boolean canCopy()
throws IOException,
AutomationException
The CanCopy, CanDelete, and CanRename properties are meant to be used in conjunction with the Copy, Delete, and Rename methods and signify whether a dataset is supported by these methods. For example, you may not delete a network feature class nor can you use the Copy method on a Geodatabase feature class. To copy Geodatabase datasets, including feature classes, geometric networks, topologies, etc., use the IGeoDBDataTransfer interface.
The CanCopy method is supported by:
