Sourceval linear_param_length : ?env:(string -> Caqti_query.t) -> Caqti_query.t -> int

linear_param_length templ is the number of linear parameters expected by a query represented by templ.

Sourceval linear_param_order : ?env:(string -> Caqti_query.t) -> Caqti_query.t -> int list list * (int * string) list

linear_param_order templ describes the parameter bindings expected for templ after linearizing parameters and lifting quoted strings out of the query:

  • The first is a list where item number i is a list of linear parameter positions to which to bind the ith incoming parameter.
  • The second is a list of pairs where the first component is the position of the linear parameter taking the place of a quoted string, and the second component is the quoted string to bind to this parameter.

All positions are zero-based.

Sourceval linear_query_string : ?env:(string -> Caqti_query.t) -> Caqti_query.t -> string

linear_query_string templ is templ where "?" is substituted for parameters and quoted strings.
