Examples of com.sun.jdo.spi.persistence.support.sqlstore.RetrieveDesc.addConstraint()

com.sun.jdo.spi.persistence.support.sqlstore.RetrieveDesc.addConstraint()
Adds a constraint on the persistent field specified by name. The valid values for operation are defined in ActionDesc. The parameter value specifies the constraint value.
By default, multiple constraints are implicitly ANDed together. If the applications want to OR together the constraints, it can explicitly add OP_OR constraints. For example, to OR together two constraints, an application can do the following:
```
 addConstraint("field1", ActionDesc.OP_EQ, "field1Value"); addConstraint("field2", ActionDesc.OP_EQ, "field2Value"); addConstraint(null, ActionDesc.OP_OR, null); 
```
The important thing to note about the above example is that the constraints are processed in postfix order, so the above example should be read as
```
 (field1 == "field1Value") OR (field2 == "field2Value") 
```

        // The entire filter consists of a boolean field only.
        // Map this to 'booleanField <> FALSE'. Note, the runtime will
        // create a JDBC parameter for the literal FALSE and call 
        // setBoolean to bind the value.
        RetrieveDesc rd = expr.getRetrieveDesc();
        rd.addConstraint(null, RetrieveDesc.OP_VALUE, Boolean.FALSE);
        expression(expr);
        rd.addConstraint(null, RetrieveDesc.OP_NE, null);
        break;
        default:
        expression(expr);
