Function sql::plan::plan

pub fn plan(
    pcx: Option<&PlanContext>, 
    catalog: &dyn SessionCatalog, 
    stmt: Statement<Raw>, 
    params: &Params
) -> Result<Plan, Error>

Produces a Plan from the purified statement stmt.

The returned plan is tied to the state of the provided catalog. If the state of the catalog changes after planning, the validity of the plan is not guaranteed.
