org.apache.derby.impl.sql.compile.StaticMethodCallNode
| StaticMethodCallNode | | public class StaticMethodCallNode extends MethodCallNode (Code) | | A StaticMethodCallNode represents a static method call from a Class
(as opposed to from an Object).
For a procedure the call requires that the arguments be ? parameters.
The parameter is *logically* passed into the method call a number of different ways.
For a application call like CALL MYPROC(?) the logically Java method call is
(in psuedo Java/SQL code) (examples with CHAR(10) parameter)
Fixed length IN parameters - com.acme.MyProcedureMethod(?)
Variable length IN parameters - com.acme.MyProcedureMethod(CAST (? AS CHAR(10))
Fixed length INOUT parameter -
String[] holder = new String[] {?}; com.acme.MyProcedureMethod(holder); ? = holder[0]
Variable length INOUT parameter -
String[] holder = new String[] {CAST (? AS CHAR(10)}; com.acme.MyProcedureMethod(holder); ? = CAST (holder[0] AS CHAR(10))
Fixed length OUT parameter -
String[] holder = new String[1]; com.acme.MyProcedureMethod(holder); ? = holder[0]
Variable length INOUT parameter -
String[] holder = new String[1]; com.acme.MyProcedureMethod(holder); ? = CAST (holder[0] AS CHAR(10))
For static method calls there is no pre-definition of an IN or INOUT parameter, so a call to CallableStatement.registerOutParameter()
makes the parameter an INOUT parameter, provided:
- the parameter is passed directly to the method call (no casts or expressions).
- the method's parameter type is a Java array type.
Since this is a dynmaic decision we compile in code to take both paths, based upon a boolean isINOUT which is dervied from the
ParameterValueSet. Code is logically (only single parameter String[] shown here). Note, no casts can exist here.
boolean isINOUT = getParameterValueSet().getParameterMode(0) == PARAMETER_IN_OUT;
if (isINOUT) {
String[] holder = new String[] {?}; com.acme.MyProcedureMethod(holder); ? = holder[0]
} else {
com.acme.MyProcedureMethod(?)
}

| bindExpression | | public JavaValueNode bindExpression(FromList fromList, SubqueryList subqueryList, Vector aggregateVector) throws StandardException(Code) | | Bind this expression. This means binding the sub-expressions,
as well as figuring out what the return type is for this expression.
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 this or an AggregateNode
exception:
StandardException - Thrown on error |
| categorize | | public boolean categorize(JBitSet referencedTabs, boolean simplePredsOnly) throws StandardException(Code) | | Categorize this predicate. Initially, this means
building a bit map of the referenced tables for each predicate.
If the source of this ColumnReference (at the next underlying level)
is not a ColumnReference or a VirtualColumnNode then this predicate
will not be pushed down.
For example, in:
select * from (select 1 from s) a (x) where x = 1
we will not push down x = 1.
NOTE: It would be easy to handle the case of a constant, but if the
inner SELECT returns an arbitrary expression, then we would have to copy
that tree into the pushed predicate, and that tree could contain
subqueries and method calls.
RESOLVE - revisit this issue once we have views.
Parameters:
referencedTabs - JBitSet with bit map of referenced FromTables
Parameters:
simplePredsOnly - Whether or not to consider methodcalls, field references and conditional nodeswhen building bit map boolean Whether or not source.expression is a ColumnReferenceor a VirtualColumnNode.
exception:
StandardException - Thrown on error |
