Return a new query containing the elements from both operands.
Return a new query containing the elements from both operands. Duplicate elements are preserved.
Get the "raw" table row that represents the table itself, as opposed to a Path for a variable of the table's type.
Get the "raw" table row that represents the table itself, as opposed to a Path for a variable of the table's type. This method should generally not be called from user code.
Remove duplicate elements.
Remove duplicate elements. When used on an ordered Query, there is no guarantee in which
order duplicates are removed. This method is equivalent to distinctOn(identity).
Remove duplicate elements which are the same in the given projection.
Remove duplicate elements which are the same in the given projection. When used on an ordered Query, there is no guarantee in which order duplicates are removed.

Encode a reference into this Rep.
Test whether this query is non-empty.
Test whether this query is non-empty.
Select all elements of this query which satisfy a predicate.
Select all elements of this query which satisfy a predicate. Unlike
withFilter, this method only allows Rep-valued predicates, so it
guards against the accidental use plain Booleans.
Applies the given filter function, if the boolean parameter p evaluates to true.
Applies the given filter function, if the boolean parameter p evaluates to true.
If not, the filter will not be part of the query.
Applies the given filter, if the Option value is defined.
Applies the given filter, if the Option value is defined. If the value is None, the filter will not be part of the query.
Build a new query by applying a function to all elements of this query and using the elements of the resulting queries.
Build a new query by applying a function to all elements of this query and using the elements of the resulting queries. This corresponds to an implicit inner join in SQL.

Partition this query into a query of pairs of a key and a nested query containing the elements for the key, according to some discriminator function.
Partition this query into a query of pairs of a key and a nested query containing the elements for the key, according to some discriminator function.
Join two queries with a cross join or inner join.
Join two queries with a cross join or inner join.
An optional join predicate can be specified later by calling on.
Join two queries with a full outer join.
Join two queries with a full outer join.
An optional join predicate can be specified later by calling on.
Both sides of the join are lifted to an Option. If at least one element on either side
matches the other side, all matching elements are returned as Some, otherwise a single
None row is returned.
Join two queries with a left outer join.
Join two queries with a left outer join.
An optional join predicate can be specified later by calling on.
The right side of the join is lifted to an Option. If at least one element on the right
matches, all matching elements are returned as Some, otherwise a single None row is
returned.
Join two queries with a right outer join.
Join two queries with a right outer join.
An optional join predicate can be specified later by calling on.
The left side of the join is lifted to an Option. If at least one element on the left
matches, all matching elements are returned as Some, otherwise a single None row is
returned.

Force a subquery to be created when using this Query as part of a larger Query.
Force a subquery to be created when using this Query as part of a larger Query. This method
should never be necessary for correctness. If a query works with an explicit .subquery call
but fails without, this should be considered a bug in Slick. The method is exposed in the API
to enable workarounds to be written in such cases.

Select all elements of this query which satisfy a predicate.
Select all elements of this query which satisfy a predicate. This method
is used when desugaring for-comprehensions over queries. There is no
reason to call it directly because it is the same as filter.
Return a query formed from this query and another query by combining corresponding elements in pairs.
Return a query formed from this query and another query by combining corresponding elements in pairs.
Return a query formed from this query and another query by combining corresponding elements with the specified function.

Represents a database table. Profiles add extension methods to TableQuery for operations that can be performed on tables but not on arbitrary queries, e.g. getting the table DDL.
