def
fromClause
: scala.List[scala.dbc.statement.Relation]
Defines the relations from which the query will obtain its data. |
abstract

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 noticeSQL'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 noticeSome 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
