}

Composite query performing operations on other result sets.

Variants

UnionAll

Return the union of the specified result sets. May return duplicate results.

Fields

union_all: Vec<QuerySetOrString>

List of query sets or references to other queries.

except: Option<Vec<String>>

Exclude matching results.

limit: Option<i32>

Maximum number of results in result set.

Union

Return the union of the specified result sets, will not return duplicate results.

Note: Using UnionAll is more efficient in general.

Fields

union: Vec<QuerySetOrString>

List of query sets or references to other queries.

except: Option<Vec<String>>

Exclude matching results.

limit: Option<i32>

Maximum number of results in result set.

Intersection

Find the common elements in the returned result set.

Fields

intersection: Vec<QuerySetOrString>

List of query sets or references to other queries.

except: Option<Vec<String>>

Exclude matching results.

limit: Option<i32>

Maximum number of results in result set.
