class Select

abstract class Select
extends scala.dbc.statement.Relation
with scala.ScalaObject
A statement that when executed on a database will return a relation. The returned relation will be a subset of a table in the database or a jointure between such subsets.

Constructor Summary

Def Summary
def fromClause : scala.List[scala.dbc.statement.Relation]
Defines the relations from which the query will obtain its data.
def groupByClause : scala.Option[scala.List[scala.dbc.statement.Expression]]
Defines the grouping of the returned relation's tuples. One tuple is returned for every group. The value of selectList must use aggregate functions for calculation.
def havingClause : scala.Option[scala.dbc.statement.Expression]
Defines conditions that must be true in the returned relation's tuples. The value expression must return a boolean can only refer to fields that are grouped or to any field from inside an aggregate function.
def selectList : scala.List[scala.dbc.statement.DerivedColumn]
Defines the output fields that a tuple in the returned relation will contain, and their content with respect to the tables in the database. If the fields are not specified (that is the list is empty), all possible input fields will be returned.

Compatibility notice

SQL's qualified asterisk select sublist is not available.

def setQuantifier : scala.Option[scala.dbc.statement.SetQuantifier]
Defines if duplicated tuples should be removed from the returned relation.

Compatibility notice

Some DBMS (PostgreSQL) allow uniqueness constrains on an arbitrary field instead of the entire tuple.

def sqlInnerString : java.lang.String
A SQL-99 compliant string representation of the relation sub- statement. This only has a meaning inside a query.
def sqlString : java.lang.String
A SQL-99 compliant string representation of the select statement.
def whereClause : scala.Option[scala.dbc.statement.Expression]
Defines condition that must be true in the returned relation's tuples. This value expression must return a boolean or boolean-compatible value. This condition is applied before any GROUP BY clause.
