Direct Known Subclasses:

ModifyColumnNode

public class ColumnDefinitionNode
extends TableElementNode

A ColumnDefinitionNode represents a column definition in a DDL statement. There will be a ColumnDefinitionNode for each column in a CREATE TABLE statement, and for the column in an ALTER TABLE ADD COLUMN statement.

                 Object autoIncrementInfo)
          throws StandardException

Initializer for a ColumnDefinitionNode

Overrides:

init in class QueryTreeNode

Parameters:

name - The name of the column

defaultNode - The default value of the column

type - A DataTypeDescriptor telling the type of the column

autoIncrementInfo - Info for autoincrement columns

Throws:

StandardException - Thrown on error

copyFrom

public void copyFrom(QueryTreeNode node)
              throws StandardException

Fill this node with a deep copy of the given node.

Overrides:

copyFrom in class TableElementNode

Throws:

StandardException

toString

public 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 TableElementNode

Returns:

This object as a String

getColumnName

public String getColumnName()

Returns the unqualified name of the column being defined.

Returns:

the name of the column

getType

public final DataTypeDescriptor getType()

Returns the data type of the column being defined.

Returns:

the data type of the column

setType

public void setType(DataTypeDescriptor dts)

Set the type of this column

getDefaultNode

public DefaultNode getDefaultNode()

Return the DefaultNode, if any, associated with this node.

Returns:

The DefaultNode, if any, associated with this node.

hasGenerationClause

public boolean hasGenerationClause()

Return true if this column has a generation clause.

getGenerationClauseNode

public GenerationClauseNode getGenerationClauseNode()

Get the generation clause.

isAutoincrementColumn

public boolean isAutoincrementColumn()

Is this an autoincrement column?

Returns:

Whether or not this is an autoincrement column.

getAutoincrementStart

public long getAutoincrementStart()

Get the autoincrement start value

Returns:

Autoincrement start value.

getAutoincrementIncrement

public long getAutoincrementIncrement()

Get the autoincrement increment value

Returns:

Autoincrement increment value.

getAutoinc_create_or_modify_Start_Increment

public long getAutoinc_create_or_modify_Start_Increment()

Get the status of this autoincrement column

Returns:

ColumnDefinitionNode.CREATE_AUTOINCREMENT - if this definition is for autoincrement column creatoin ColumnDefinitionNode.MODIFY_AUTOINCREMENT_RESTART_VALUE - if this definition is for alter sutoincrement column to change the start value ColumnDefinitionNode.MODIFY_AUTOINCREMENT_INC_VALUE if this definition is for alter autoincrement column to change the increment value

printSubNodes

public void printSubNodes(int depth)

Prints the sub-nodes of this object. See QueryTreeNode.java for how tree printing is supposed to work.

Overrides:

printSubNodes in class QueryTreeNode

Parameters:

depth - The depth of this node in the tree
