| DeleteNode | | public class DeleteNode extends DMLModStatementNode (Code) | | A DeleteNode represents a DELETE statement. It is the top-level node
for the statement.
For positioned delete, there may be no from table specified.
The from table will be derived from the cursor specification of
the named cursor.

| bind | | public QueryTreeNode bind() throws StandardException(Code) | | Bind this DeleteNode. This means looking up tables and columns and
getting their types, and figuring out the result types of all
expressions, as well as doing view resolution, permissions checking,
etc.
If any indexes need to be updated, we add all the columns in the
base table to the result column list, so that we can use the column
values as look-up keys for the index rows to be deleted. Binding a
delete will also massage the tree so that the ResultSetNode has
column containing the RowLocation of the base row.
The bound query tree
exception:
StandardException - Thrown on error |
| generate | | public void generate(ActivationClassBuilder acb, MethodBuilder mb) throws StandardException(Code) | | Code generation for delete.
The generated code will contain:
o A static member for the (xxx)ResultSet with the RowLocations
o The static member will be assigned the appropriate ResultSet within
the nested calls to get the ResultSets. (The appropriate cast to the
(xxx)ResultSet will be generated.)
o The CurrentRowLocation() in SelectNode's select list will generate
a new method for returning the RowLocation as well as a call to
that method which will be stuffed in the call to the
ProjectRestrictResultSet.
o In case of referential actions, this function generate an
array of resultsets on its dependent tables.
Parameters:
acb - The ActivationClassBuilder for the class being built
Parameters:
mb - The execute() method to be built
exception:
StandardException - Thrown on error |
| getPrivType | | int getPrivType()(Code) | | |
| getReadMap | | public FormatableBitSet getReadMap(DataDictionary dd, TableDescriptor baseTable) throws StandardException(Code) | | Gets the map of all columns which must be read out of the base table.
These are the columns needed to:
o maintain indices
o maintain foreign keys
The returned map is a FormatableBitSet with 1 bit for each column in the
table plus an extra, unsued 0-bit. If a 1-based column id must
be read from the base table, then the corresponding 1-based bit
is turned ON in the returned FormatableBitSet.
Parameters:
dd - the data dictionary to look in
Parameters:
baseTable - the base table descriptor a FormatableBitSet of columns to be read out of the base table
exception:
StandardException - Thrown on error |

| init | | public void init(Object targetTableName, Object queryExpression)(Code) | | Initializer for a DeleteNode.
Parameters:
targetTableName - The name of the table to delete from
Parameters:
queryExpression - The query expression that will generatethe rows to delete from the given table |
| referencesSessionSchema | | public boolean referencesSessionSchema() throws StandardException(Code) | | Return true if the node references SESSION schema tables (temporary or permanent)
true if references SESSION schema tables, else false
exception:
