# CALL statement (FB 6.0)
`CALL` statement is similar to `EXECUTE PROCEDURE`, but allow the caller to get specific output parameters, or none.
When using the positional or mixed parameter passing, output parameters follows the input ones.
When passing `NULL` to output parameters, they are ignored, and in the case of DSQL, not even returned.
In DSQL output parameters are specified using `?`, and in PSQL using the target variables or parameters.
## Syntax
```
<call statement> ::=
CALL [<package name> .] <procedure name> (<arguments>)
<arguments> ::=
<positional arguments> |
[ {<positional arguments>,} ] <named arguments>
<positional arguments> ::=
<value or default> [ {, <value or default>}... ]
<named arguments> ::=
<named argument> [ {, <named argument>}... ]
<named argument> ::=
<argument name> => <value or default>
<value or default> ::=
<value> |
DEFAULT
```
## Examples
```
create or alter procedure insert_customer (
last_name varchar(30),
first_name varchar(30)
) returns (
id integer,
full_name varchar(62)
)
as
begin
insert into customers (last_name, first_name)
values (:last_name, :first_name)
returning id, last_name || ', ' || first_name
into :id, :full_name;
end
```
```
-- Not all output parameters are necessary.
call insert_customer(
'LECLERC',
'CHARLES',
?)
```
```
-- Ignore first output parameter (using NULL) and get the second.
call insert_customer(
'LECLERC',
'CHARLES',
null,
?)
```
```
-- Ignore ID output parameter.
call insert_customer(
'LECLERC',
'CHARLES',
full_name => ?)
```
```
-- Pass inputs and get outputs using named arguments.
call insert_customer(
last_name => 'LECLERC',
first_name => 'CHARLES',
last_name => ?,
id => ?)
```
```
create or alter procedure do_something_and_insert_customer returns (
out_id integer,
out_full_name varchar(62)
)
as
declare last_name varchar(30);
declare first_name varchar(30);
begin
call insert_customer(
last_name,
first_name,
out_id,
full_name => out_full_name);
end
```
