Method Detail

init

public void init(java.lang.Object sequenceName,
                 java.lang.Object dataType,
                 java.lang.Object initialValue,
                 java.lang.Object stepValue,
                 java.lang.Object maxValue,
                 java.lang.Object minValue,
                 java.lang.Object cycle)
          throws StandardException

Initializer for a CreateSequenceNode

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

sequenceName - The name of the new sequence

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

Throws:

StandardException - on error

toString

public java.lang.String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class DDLStatementNode

Returns:

This object as a String

bindStatement

public void bindStatement()
                   throws StandardException

Bind this CreateSequenceNode. The main objectives of this method are to resolve the schema name, determine privilege checks, and vet the variables in the CREATE SEQUENCE statement.

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

statementToString

public java.lang.String statementToString()

Specified by:

statementToString in class StatementNode

makeConstantAction

public ConstantAction makeConstantAction()

Create the Constant information that will drive the guts of Execution.

Overrides:

makeConstantAction in class QueryTreeNode

Throws:

StandardException - Thrown on failure
