Method Details

distinct

public SelectQuery distinct()

Specify the query's projection to be distinct

Returns:

this

See Also:

• Projection.distinct()

distinct

public SelectQuery distinct(boolean isDistinct)

Specify if the query's projection should be distinct or not

Parameters:

isDistinct - if this query's projection should be distinct

Returns:

this

See Also:

• Projection.distinct(boolean)

all

public SelectQuery all()

Specify that this query's projection should select all in-scope expressions

NOTE: setting this takes precedence over any expressions added to the projection via select(Projectable...) or select(Projection) when printing

Returns:

this

See Also:

• Projection.all()

all

public SelectQuery all(boolean selectAll)

Specify if this query's projection should select all in-scope expressions or not.

NOTE: if called with true, this setting will take precedence over any expressions added to the projection via select(Projectable...) or select(Projection) when converting to string via OuterQuery.getQueryString()

Parameters:

selectAll - if all in-scope expressions should be selected

Returns:

this

See Also:

• Projection.all(boolean)

select

public SelectQuery select(Projectable... projectables)

Add expressions to the query's projection

NOTE: if SELECT * has been specified (by all() or calling all(boolean) with true), that will take precedence over specified expressions when converting to string via OuterQuery.getQueryString()

Parameters:

projectables - expressions to add

Returns:

this

See Also:

• Projection.select(Projectable...)

select

public SelectQuery select(Projection select)

Set this query's projection

NOTE: if SELECT * has been specified (by all() or calling all(boolean) with true), that will take precedence over specified expressions when converting to string via OuterQuery.getQueryString()

Parameters:

select - the Projection to set

Returns:

this

getQueryActionString

protected String getQueryActionString()

Specified by:

getQueryActionString in class Query<SelectQuery>
