Method Summary

Modifier and Type	Method	Description
long	currVal()	Get the current value of the sequence (CURRVAL) Returns the last value generated by NEXTVAL
String	getComment()
Instant	getCreatedTime()	When this sequence was created, as SHOW SEQUENCES reports it.

long	nextVal()	Get the next value in the sequence (NEXTVAL)
long	peekNextValue()	The value the NEXT call to nextVal() will return, without consuming it — the catalog's NEXT_VALUE.
void	setComment(String comment)
void	setCurrentValue(long value)	Set the current value (used by ALTER SEQUENCE)

 String comment)

Method Details

nextVal

public long nextVal()

Get the next value in the sequence (NEXTVAL)

currVal

public long currVal()

Get the current value of the sequence (CURRVAL) Returns the last value generated by NEXTVAL

getCurrentValueRaw

public long getCurrentValueRaw()

Get the current internal value (for cloning purposes) This does not check if NEXTVAL was called

peekNextValue

public long peekNextValue()

The value the NEXT call to nextVal() will return, without consuming it — the catalog's NEXT_VALUE. On a sequence nothing has drawn from yet this is its START value.

setCurrentValue

public void setCurrentValue(long value)

Set the current value (used by ALTER SEQUENCE)

getName

public String getName()

getOwner

public String getOwner()

setOwner

public void setOwner(String owner)

getStartValue

public long getStartValue()

getIncrement

public long getIncrement()

setIncrement

public void setIncrement(long increment)

Change the step applied by future NEXTVAL calls (ALTER SEQUENCE … SET INCREMENT).

getCreatedTime

public Instant getCreatedTime()

When this sequence was created, as SHOW SEQUENCES reports it.

isOrder

public boolean isOrder()

getComment

public String getComment()

setComment

public void setComment(String comment)

getObjectType

public String getObjectType()

toString

public String toString()

Overrides:
