Method Detail

init

public void init(java.lang.Object newObjectName,
                 java.lang.Object resultColumns,
                 java.lang.Object queryExpression,
                 java.lang.Object checkOption,
                 java.lang.Object qeText,
                 java.lang.Object orderCols,
                 java.lang.Object offset,
                 java.lang.Object fetchFirst,
                 java.lang.Object hasJDBClimitClause)
          throws StandardException

Initializer for a CreateViewNode

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

newObjectName - The name of the table to be created

resultColumns - The column list from the view definition, if specified

queryExpression - The query expression for the view

checkOption - The type of WITH CHECK OPTION that was specified (NONE for now)

qeText - The text for the queryExpression

orderCols - ORDER BY list

offset - OFFSET if any, or null

fetchFirst - FETCH FIRST if any, or null

hasJDBClimitClause - True if the offset/fetchFirst clauses come from JDBC limit/offset escape syntax

Throws:

StandardException - Thrown 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

statementToString

public java.lang.String statementToString()

Specified by:

statementToString in class StatementNode

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

getCheckOption

public int getCheckOption()

getProviderInfo

public ProviderInfo[] getProviderInfo()

getColumnInfo

public ColumnInfo[] getColumnInfo()

bindStatement

public void bindStatement()
                   throws StandardException

Bind this CreateViewNode. This means doing any static error checking that can be done before actually creating the table. For example, verifying that the ResultColumnList does not contain any duplicate column names.

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

bindViewDefinition

private ProviderInfo[] bindViewDefinition(DataDictionary dataDictionary,
                                          CompilerContext compilerContext,
                                          LanguageConnectionContext lcc,

                                          ResultSetNode queryExpr,
                                          ContextManager cm)
                                   throws StandardException

Bind the query expression for a view definition.

Parameters:

dataDictionary - The DataDictionary to use to look up columns, tables, etc.

Returns:

Array of providers that this view depends on.

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
