java.lang.Objectorg.eclipse.datatools.connectivity.oda.spec.ValueExpression
public abstract class ValueExpression
The abstract base class for an ODA expression
 that resolves to a value.
 It may be associated with an ExpressionVariable or
 ExpressionArguments in an ODA query specification.
 
It is the responsibility of an ODA driver to resolve an expression,
 when evaluating it with a query result spec expression.
 This may be extended to represent complex types of value expression.

odaDataTypeCode - the ODA data type code of this variable;

              throws OdaException
OdaException - if validation failed. The concrete cause is

public void validate(ValidationContext context)
              throws OdaException
context - context for validation; may be null which would limit the scope of validation
OdaException - if validation failed. The concrete cause is 
          defined by the subclass implementing this method.
