Besides all the other solutions my colleagues gave you you can use EXTFILE
too and count with a variable file name.

Sorry - forgot the into

It helps if you know the library, (table_schema)

select number_rows
into :count
from qsys2.systablestat
where table_name = trim(upper(:thefile))
and table_schema = trim(upper(:thelibrary));

However, you can use system catalog:

select number_rows
from qsys2.systablestat
where table_name = trim(upper(:thefile));

It helps if you know the library, (table_schema)

select number_rows
from qsys2.systablestat
where table_name = trim(upper(:thefile))
and table_schema = trim(upper(:thelibrary));

You cannot do a dynamic select like that.
Dynamic selects are for cursors.
You need to define a cursor and fetch the cursor result into your field.
'Execute immediate' does not return data it updates/deletes/drops/inserts
etc.

The program log says COUNT is not defined or usable. Any idea's?

Dcl-s stmt char(100) ;
Dcl-s x char(2) inz('10') ;
Dcl-s count zoned(5) ;
Dcl-s thefile char(10);

thefile = ('co' + x);

stmt = 'select count(*) into :count' +
' from ' + %trim(thefile) ;

exec sql execute immediate :stmt ;

if count > 0 ;
endif ;
