Returns:

the ordering

Throws:

InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test

column

Column column(java.lang.String selectorName,
              java.lang.String propertyName,
              java.lang.String columnName)
              throws InvalidQueryException,
                     RepositoryException

Identifies a property in the specified selector to include in the tabular view of query results.

The query is invalid if:

• selectorName is not the name of a selector in the query, or
• propertyName is specified but does not evaluate to a scalar value, or
• propertyName is specified but columnName is omitted, or
• propertyName is omitted but columnName is specified, or
• the columns in the tabular view are not uniquely named, whether those column names are specified by columnName (if propertyName is specified) or generated as described above (if propertyName is omitted).

If propertyName is specified but, for a node-tuple, the selector node does not have a property named propertyName, the query is valid and the column has null value.

Parameters:

selectorName - the selector name; non-null

propertyName - the property name, or null to include a column for each single-value non-residual property of the selector's node type

columnName - the column name; must be null if propertyName is null; must be non-null if propertyName is non-null.

Returns:

the column; non-null

Throws:

InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
