| ResultColumn | | public class ResultColumn extends ValueNode implements ResultColumnDescriptor,Comparable(Code) | | A ResultColumn represents a result column in a SELECT, INSERT, or UPDATE
statement. In a SELECT statement, the result column just represents an
expression in a row being returned to the client. For INSERT and UPDATE
statements, the result column represents an column in a stored table.
So, a ResultColumn has to be bound differently depending on the type of
statement it appears in.

| bindExpression | | public ValueNode bindExpression(FromList fromList, SubqueryList subqueryList, Vector aggregateVector) throws StandardException(Code) | | Bind this expression. This means binding the sub-expressions.
In this case, we figure out what the result type of this result
column is when we call one of the bindResultColumn*() methods.
The reason is that there are different ways of binding the
result columns depending on the statement type, and this is
a standard interface that does not take the statement type as
a parameter.
Parameters:
fromList - The FROM list for the query thisexpression is in, for binding columns.
Parameters:
subqueryList - The subquery list being built as we find SubqueryNodes
Parameters:
aggregateVector - The aggregate vector being built as we find AggregateNodes The new top of the expression tree.
exception:

| bindResultColumnByName | | public void bindResultColumnByName(TableDescriptor tableDescriptor, int columnId) throws StandardException(Code) | | Bind this result column by its name and set the VirtualColumnId.
This is useful for update statements, and for INSERT statements
like "insert into t (a, b, c) values (1, 2, 3)" where the user
specified a column list.
An exception is thrown when a columnDescriptor cannot be found for a
given name. (There is no column with that name.)
NOTE: We must set the VirtualColumnId here because INSERT does not
construct the ResultColumnList in the usual way.
Parameters:
tableDescriptor - The descriptor for the table beingupdated or inserted into
Parameters:
columnId - The ordinal position of the columnin the table, starting at 1. (Used toset the VirtualColumnId.)
exception:
StandardException - Thrown on error |
| bindResultColumnByPosition | | void bindResultColumnByPosition(TableDescriptor tableDescriptor, int columnId) throws StandardException(Code) | | Bind this result column by ordinal position and set the VirtualColumnId.
This is useful for INSERT statements like "insert into t values (1, 2, 3)",
where the user did not specify a column list.
If a columnDescriptor is not found for a given position, then
the user has specified more values than the # of columns in
the table and an exception is thrown.
NOTE: We must set the VirtualColumnId here because INSERT does not
construct the ResultColumnList in the usual way.
Parameters:
tableDescriptor - The descriptor for the table beinginserted into
Parameters:
columnId - The ordinal position of the columnin the table, starting at 1.
exception:
StandardException - Thrown on error |
| bindResultColumnToExpression | | public void bindResultColumnToExpression() throws StandardException(Code) | | Bind the result column to the expression that lives under it.
All this does is copy the datatype information to this node.
This is useful for SELECT statements, where the result type
of each column is the type of the column's expression.
exception:
StandardException - Thrown on error |
| checkStorableExpression | | public void checkStorableExpression(ResultColumn toStore) throws StandardException(Code) | | This verifies that the expression is storable into the result column.
It checks versus the given ResultColumn.
This method should not be called until the result column and
expression both have a valid type, i.e. after they are bound
appropriately. Its use is for statements like insert, that need to
verify if a given value can be stored into a column.
exception:
StandardException - thrown if types not suitable. |
| checkStorableExpression | | public void checkStorableExpression() throws StandardException(Code) | | This verifies that the expression is storable into the result column.
It checks versus the expression under this ResultColumn.
This method should not be called until the result column and

appropriately. Its use is for statements like update, that need to
verify if a given value can be stored into a column.
exception:
StandardException - thrown if types not suitable. |

exception:
StandardException - Thrown on error |

The variant type can be:
VARIANT - variant within a scan
(method calls and non-static field access)

CONSTANT - constant
The variant type for the underlying expression.

|
| getTableNumber | | public int getTableNumber() throws StandardException(Code) | | Search the tree beneath this ResultColumn until we find
the number of the table to which this RC points, and
return that table number. If we can't determine which
table this RC is for, then return -1.
There are two places we can find the table number: 1) if
our expression is a ColumnReference, then we can get the
target table number from the ColumnReference and that's
it; 2) if expression is a VirtualColumnNode, then if
the VirtualColumnNode points to a FromBaseTable, we can
get that FBT's table number; otherwise, we walk the
VirtualColumnNode-ResultColumn chain and do a recursive
search.
