Constructor Detail

SQLIntervalImpl

public SQLIntervalImpl(IntervalDataType startField,
                       java.lang.Integer startFieldPrecision,
                       IntervalDataType endField,
                       java.lang.Integer secondFracs)

Method Detail

doesEqual

protected boolean doesEqual(SQLInterval another)

Specified by:

doesEqual in class org.atp.spi.TypeableImpl<SQLDataType,SQLInterval>

getStartField

public IntervalDataType getStartField()

Returns the start field type for this INTERVAL.

Specified by:

getStartField in interface SQLInterval

Returns:

The start field type for this INTERVAL.

getStartFieldPrecision

public java.lang.Integer getStartFieldPrecision()

Return the start field precision for this INTERVAL. May be null if none specified.

Specified by:

getStartFieldPrecision in interface SQLInterval

Returns:

The start field precision for this INTERVAL.

getEndField

public IntervalDataType getEndField()

Returns the end field precision for this INTERVAL. Will always be null for single datetime field intervals.

Specified by:

getEndField in interface SQLInterval

Returns:

The end field precision for this INTERVAL.

getSecondFracs

public java.lang.Integer getSecondFracs()

Returns the fraction seconds precision for this INTERVAL. Will always be null if the end field type is not IntervalDataType.SECOND, or if this is single datetime field interval, and its start type is not IntervalDataType.SECOND.

Specified by:

getSecondFracs in interface SQLInterval

Returns:

The fraction seconds precision for this INTERVAL.
