Method Detail

getSupportedFunctions

public java.util.List getSupportedFunctions()

Description copied from class: BasicConnectorCapabilities

Return null to indicate no functions are supported.

Specified by:

getSupportedFunctions in interface ConnectorCapabilities

Overrides:

getSupportedFunctions in class JDBCCapabilities

Returns:

null

See Also:

com.metamatrix.data.ConnectorCapabilities#getSupportedFunctions()

supportsInlineViews

public boolean supportsInlineViews()

Description copied from interface: ConnectorCapabilities

Support indicates connector can accept inline views (subqueries in the FROM clause).

Specified by:

supportsInlineViews in interface ConnectorCapabilities

Overrides:

supportsInlineViews in class JDBCCapabilities

See Also:

ConnectorCapabilities.supportsInlineViews()

supportsOrderByInInlineViews

public boolean supportsOrderByInInlineViews()

supportsFunctionsInGroupBy

public boolean supportsFunctionsInGroupBy()

Description copied from interface: ConnectorCapabilities

Support indicates that the connector supports functions in GROUP BY, such as: SELECT dayofmonth(theDate), COUNT(*) FROM table GROUP BY dayofmonth(theDate)

This capability requires both ConnectorCapabilities.supportsAggregates() and ConnectorCapabilities.supportsScalarFunctions() to be true as well to take effective.

Specified by:

supportsFunctionsInGroupBy in interface ConnectorCapabilities

Overrides:

supportsFunctionsInGroupBy in class BasicConnectorCapabilities

Since:

5.0

See Also:

ConnectorCapabilities.supportsFunctionsInGroupBy()

supportsRowLimit

public boolean supportsRowLimit()

Description copied from interface: ConnectorCapabilities

Gets whether the connector can limit the number of rows returned by a query.

Specified by:

supportsRowLimit in interface ConnectorCapabilities

Overrides:

supportsRowLimit in class BasicConnectorCapabilities

supportsExcept

public boolean supportsExcept()

Description copied from interface: ConnectorCapabilities

Support indicates that the connector supports the EXCEPT of two queries.

Specified by:

supportsExcept in interface ConnectorCapabilities

Overrides:

supportsExcept in class BasicConnectorCapabilities

See Also:

BasicConnectorCapabilities.supportsExcept()

supportsIntersect

public boolean supportsIntersect()

Description copied from interface: ConnectorCapabilities

Support indicates that the connector supports the INTERSECT of two queries.

Specified by:

supportsIntersect in interface ConnectorCapabilities

Overrides:

supportsIntersect in class BasicConnectorCapabilities

See Also:

BasicConnectorCapabilities.supportsIntersect()
