```
public CorrelatedSelectPlan(RetrieveDesc desc,
                            SQLStoreManager store,
                            ForeignFieldDesc parentField,
                            SelectQueryPlan parentPlan)
```
- Method Detail
  - processConstraints
```
protected void processConstraints()
```
    The constraints for correlated subqueries are added here. The constraints are:
    
    The correlated constraint joining this subquery with the parent plan
    
    A join constraint if the parent field uses join table
    Overrides:
    
    processConstraints in class SelectQueryPlan
  - doCorrelatedJoin
```
protected abstract void doCorrelatedJoin()
```
    Must be implemented by the sub classes.
  - addQueryTables
```
protected void addQueryTables(ArrayList columnList,
                              ClassDesc config)
```
    Adds the query tables corresponding to the columns in columnList.
    
    Parameters:
    
    columnList - List of columns.
    
    config - Class configuration corresponding to columns.
