resetQuery method
void
resetQuery()
Drops every clause accumulated so far, leaving the table, alias and connection in place so the builder can be reused for a fresh query.
A builder never clears itself after executing — paginate depends on
that, since it runs count() and get() off the same clauses. But a
builder that outlives one query (a Model held on a relation, say)
would otherwise carry its old WHEREs into the next one.
Implementation
void resetQuery() {
conditions.clear();
bindings.clear();
selectColumns = [];
joins = [];
unions = [];
}
