pub fn union<Q: HasCompounds>(query: impl IntoExpr) -> impl Mod<Q>Expand description
UNION <select-core> — rows of either, duplicates removed.
The operand is written bare: a parenthesised select is not a compound operand in
SQLite. Pass a SelectQuery directly, or
query for one built elsewhere — not
subquery, which adds the parentheses that would make this a
syntax error.
