Method Detail

init

public void init(java.lang.Object newObjectName,
                 java.lang.Object tableElementList,
                 java.lang.Object properties,
                 java.lang.Object lockGranularity)
          throws StandardException

Initializer for a CreateTableNode for a base table

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

newObjectName - The name of the new object being created (ie base table)

tableElementList - The elements of the table: columns, constraints, etc.

properties - The optional list of properties associated with the table.

lockGranularity - The lock granularity.

Throws:

StandardException - Thrown on error

init

public void init(java.lang.Object newObjectName,
                 java.lang.Object tableElementList,
                 java.lang.Object properties,
                 java.lang.Object onCommitDeleteRows,
                 java.lang.Object onRollbackDeleteRows)
          throws StandardException

Initializer for a CreateTableNode for a global temporary table

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

newObjectName - The name of the new object being declared (ie temporary table)

tableElementList - The elements of the table: columns, constraints, etc.

properties - The optional list of properties associated with the table.

onCommitDeleteRows - If true, on commit delete rows else on commit preserve rows of temporary table.

onRollbackDeleteRows - If true, on rollback, delete rows from temp tables which were logically modified. true is the only supported value

Throws:

StandardException - Thrown on error

init

public void init(java.lang.Object newObjectName,
                 java.lang.Object resultColumns,
                 java.lang.Object queryExpression)
          throws StandardException

Initializer for a CreateTableNode for a base table create from a query

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

newObjectName - The name of the new object being created (ie base table).

resultColumns - The optional column list.

queryExpression - The query expression for the table.

Throws:

StandardException - Thrown on error

tempTableSchemaNameCheck

private java.lang.Object tempTableSchemaNameCheck(java.lang.Object objectName)
                                           throws StandardException

If no schema name specified for global temporary table, SESSION is the implicit schema. Otherwise, make sure the specified schema name for global temporary table is SESSION.

Parameters:

objectName - The name of the new object being declared (ie temporary table)

Throws:

StandardException

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

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 to indent the sub-nodes

statementToString

public java.lang.String statementToString()

Specified by:

statementToString in class StatementNode

bindStatement

public void bindStatement()
                   throws StandardException

Bind this CreateTableNode. This means doing any static error checking that can be done before actually creating the base table or declaring the global temporary table. For eg, verifying that the TableElementList does not contain any duplicate column names.

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

referencesSessionSchema

public boolean referencesSessionSchema()
                                throws StandardException

Return true if the node references SESSION schema tables (temporary or permanent)

Overrides:

referencesSessionSchema in class QueryTreeNode

Returns:

true if references SESSION schema tables, else false

Throws:

StandardException - Thrown on error

makeConstantAction

public ConstantAction makeConstantAction()
                                  throws StandardException

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

Overrides:

makeConstantAction in class QueryTreeNode

Throws:

StandardException - Thrown on failure

acceptChildren

void acceptChildren(Visitor v)
              throws StandardException

Accept the visitor for all visitable children of this node.

Overrides:

acceptChildren in class QueryTreeNode

Parameters:

v - the visitor

Throws:

StandardException - on error
