CreateSequenceConstantAction
public CreateSequenceConstantAction(java.lang.String schemaName, java.lang.String sequenceName, DataTypeDescriptor dataType, long initialValue, long stepValue, long maxValue, long minValue, 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 createddataType
- Exact numeric type of the new sequenceinitialValue
- Starting valuestepValue
- Increment amountmaxValue
- Largest value returned by the sequence generatorminValue
- Smallest value returned by the sequence generatorcycle
- True if the generator should wrap around, false otherwise
