# Named arguments for function and procedure calling (FB 6.0)
Named arguments allows you to specify function and procedure arguments by their names, rather than only by their positions.
It is especially useful when the routine have a lot of parameters and you want to specify them in arbitrary order or not specify some of them who have default values.
As the positional syntax, all arguments without default values are required to be present in the call.
It's currently not possible to mix positional and named arguments in the same call.
## Syntax
```
<function call> ::=
[<package name> .] <function_name>( [<arguments>] )
<procedure selection> ::=
[<package name> .] <procedure_name> [( <arguments> )]
<execute procedure> ::=
EXECUTE PROCEDURE [<package name> .] <procedure name>
[{ (<arguments>) | <arguments> }]
[RETURNING_VALUES ...]
<arguments> ::=
<named arguments>
<positional arguments>
<named arguments> ::=
<named argument> [ {, <named argument>}... ]
<named argument> ::=
<argument name> => <value>
```
## Examples
```
select function_name(parameter2 => 'Two', parameter1 => 1)
from rdb$database
```
```
execute procedure insert_customer(
last_name => 'SCHUMACHER',
first_name => 'MICHAEL')
```
```
select *
from get_customers(city_id => 10, last_name => 'SCHUMACHER')
```

the cache cleanup (MET_clear_cache). Since the current
tdbb default pool is different from the procedure's one,
it's dangerous to copy a pointer from one request to another.
As an experiment, I've decided to copy format by value
instead of copying the reference. Since Format structure
doesn't contain any pointers, it should be safe to use a
default assignment operator which does a simple byte copy.
This change fixes one serious bug in the current codebase.
I think that this situation can (and probably should) be
handled by the metadata cache (via incrementing prc_use_count)
to avoid unexpected cache cleanups, but that area is out of my
