Class IQueryDefProxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.geodatabase.IQueryDefProxy

All Implemented Interfaces:

IQueryDef, Externalizable, Serializable

Direct Known Subclasses:

IQueryDef2Proxy

public class IQueryDefProxy
extends com.esri.arcgis.interop.Dispatch
implements IQueryDef, Serializable

Provides access to members that control attribute based queries.

Description

IQueryDef sets the parameters needed to create an attribute query. The name of the table and a string defining the where clause are required. An optional list of columns may be included to specify the columns to be retrieved. If no columns are specified, all columns will be returned.

IQueryDef only can be used with ArcSDE, Personal and File Geodatabase data sources. QueryDef cursor are not supported on historical representations of datasets.

Remarks

The IQueryDef interface allows the definition of an attribute query based on one or more tables. Multiple table joins may be defined through the use of this interface.

In order to access the geometry of a feature returned by the query the shape field must be included in the SubFields definition.

If multiple feature classes are specified in the IQueryDef.Tables property it is the application developer's responsibility to ensure that only one shape attribute is specified in the IQueryDef.SubFields property.

getTables

public String getTables()
                 throws IOException,
                        AutomationException

The comma delimited list of table names for the query.

Description

Get or put a comma delimited string of tables for use in the query from the Tables data member.

Remarks

Returns a string containing the name of a single table (or a list of table names when used in a join). When used with an ArcSDE datasource, the table name will be prefixed with the owner name (owner.mytable) if the table is not owned by the current workspace.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getTables in interface IQueryDef

Returns:

The tables

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSubFields

public String getSubFields()
                    throws IOException,
                           AutomationException

The comma delimited list of field names for the query.

Description

SubFields returns or sets a comma delimited list of fields.

Remarks

The following formats are used for the SubFields property of a QueryDef against an ArcSDE datasource:

Format 1: "*"
This returns all fields on all tables. If duplicate column names are found, the field names will be prefixed with the table name (table.field_name).

Format 2: "field1,field2,field3"
Returns only the fields requested. (Separate field names by commas but do not add a space after or before the comma)

Format 3: "table1.*,table2.field1,table3.field2"
Returns all of the fields from table1, field1 from table2 and field 2 from table3.
