insert!clj
(insert! modelable row-or-rows-or-queryable)(insert! modelable columns row-vectors)(insert! :conn connectable modelable row-or-rows)(insert! modelable k v & more)(insert! :conn connectable modelable columns row-vectors)(insert! :conn connectable modelable k v & more)Insert a row or rows into the database. Returns the number of rows inserted.
This function is pretty flexible in what it accepts:
Insert a single row with key-value args:
(t2/insert! :models/venues :name "Grant & Green", :category "bar")
Insert a single row as a map:
(t2/insert! :models/venues {:name "Grant & Green", :category "bar"})
Insert multiple row maps:
(t2/insert! :models/venues [{:name "Grant & Green", :category "bar"}
{:name "Savoy Tivoli", :category "bar"}])
Insert rows with a vector of column names and a vector of value maps:
(t2/insert! :models/venues [:name :category] [["Grant & Green" "bar"]
["Savoy Tivoli" "bar"]])
As with other Toucan 2 functions, you can optionally pass a connectable if you pass :conn as the first arg. Refer to
the :toucan2.insert/args spec for the complete syntax.
Named connectables can also be used to define the rows:
(t2/define-named-query ::named-rows
{:rows [{:name "Grant & Green", :category "bar"}
{:name "North Beach Cantina", :category "restaurant"}]})
(t2/insert! :models/venues ::named-rows)
Insert a row or rows into the database. Returns the number of rows inserted.
This function is pretty flexible in what it accepts:
Insert a single row with key-value args:
```clj

```
Insert a single row as a map:
```clj
(t2/insert! :models/venues {:name "Grant & Green", :category "bar"})

Insert multiple row maps:

Insert rows with a vector of column names and a vector of value maps:
```clj
(t2/insert! :models/venues [:name :category] [["Grant & Green" "bar"]
["Savoy Tivoli" "bar"]])
```
As with other Toucan 2 functions, you can optionally pass a connectable if you pass `:conn` as the first arg. Refer to
the `:toucan2.insert/args` spec for the complete syntax.
Named connectables can also be used to define the rows:
```clj
(t2/define-named-query ::named-rows

Returns the inserted object as a map.
Like [[insert-returning-instances!]], but for one-row insertions. Returns the inserted object as a map.

Like [[insert!]], but returns a vector of maps representing the inserted objects.

(insert-returning-pk! modelable row-or-rows-or-queryable)(insert-returning-pk! modelable columns row-vectors)(insert-returning-pk! :conn connectable modelable row-or-rows)(insert-returning-pk! modelable k v & more)(insert-returning-pk! :conn connectable modelable columns row-vectors)(insert-returning-pk! :conn connectable modelable k v & more)Like insert-returning-pks!, but for one-row insertions. For models with a single primary key, this returns just the
new primary key as a scalar value (e.g. 1). For models with a composite primary key, it will return a single tuple
as determined by model/primary-keys (e.g. [1 "Cam"]).
Like [[insert-returning-pks!]], but for one-row insertions. For models with a single primary key, this returns just the new primary key as a scalar value (e.g. `1`). For models with a composite primary key, it will return a single tuple as determined by [[model/primary-keys]] (e.g. `[1 "Cam"]`).

inserted. The primary keys are determined by model/primary-keys. For models with a single primary key, this
returns a vector of single values, e.g. [1 2] if the primary key is :id and you've inserted rows 1 and 2; for
composite primary keys this returns a vector of tuples where each tuple has the value of corresponding primary key as
returned by model/primary-keys, e.g. for composite PK [:id :name] you might get [[1 "Cam"] [2 "Sam"]].
