CreateSequenceConstantAction (Apache Derby V10.14 Internals)

java.lang.Object
- org.apache.derby.impl.sql.execute.DDLConstantAction
- - org.apache.derby.impl.sql.execute.CreateSequenceConstantAction

All Implemented Interfaces:

ConstantAction
```
class CreateSequenceConstantAction
extends DDLConstantAction
```
This class performs actions that are ALWAYS performed for a CREATE SEQUENCE statement at execution time. These SQL objects are stored in the SYS.SYSSEQUENCES table.

                                    boolean cycle)
```
    Make the ConstantAction for a CREATE SEQUENCE statement. When executed, will create a sequence by the given name.
    
    Parameters:
    
    sequenceName - The name of the sequence being created
    
    dataType - Exact numeric type of the new sequence
    
    initialValue - Starting value
    
    stepValue - Increment amount
    
    maxValue - Largest value returned by the sequence generator
    
    minValue - Smallest value returned by the sequence generator
    
    cycle - True if the generator should wrap around, false otherwise

public void executeConstantAction(Activation activation)
                           throws StandardException
```
    This is the guts of the Execution-time logic for CREATE SEQUENCE.
    
    Parameters:
    
    activation - The execution environment for this constant action.
    
    Throws:
    
    StandardException - Thrown on failure
