Re: Find string in multiple it's files using sql services -- MIDRANGE-L

Thanks, Birgitta! I finally got a solution, similar to yours, might be the first real use I've made of LATERAL.

The problem was, I got a message from Ifs_Read that said '/YourFolder/Dir2/Dir3' was not valid for the operation - well, obviously, because it is a directory!! I did not have the named parameter Object_Type_List - now I do. Here's what I came up with using CROSS JOIN LATERAL with Ifs_Read - and a couple global variables.

This doesn't need to be run under commitment control, although that isn't usually a problem, as I recall. Performance, in any case, is probably very dependent on how many streamed files there are and their size.

-- category: Custom
-- description: Find IFS files for 2 specific values
create or replace variable typeofxml varchar(50);
set typeofxml = '<Service>';
create or replace variable testvalue varchar(32);
set testvalue = 'DGDO5778';

SELECT path_name,
       line_number,
       line
    FROM TABLE (
             qsys2.ifs_object_statistics(start_path_name => '/Lvl1/Lvl2/Guids', OBJECT_TYPE_LIST => '*STMF')
         ) a
         CROSS JOIN
             LATERAL (
                 SELECT line_number,
                        line
                     FROM TABLE (
                             qsys2.ifs_read(
                                 path_name => a.path_name, end_of_line => 'ANY', maximum_line_length => default,
                                 ignore_errors => 'NO')
                         )
             ) b
    WHERE LOCATE(UPPER(testvalue), UPPER(line)) > 0 and LOCATE(UPPER(typeofxml), UPPER(line)) > 0;

I do so appreciate the efforts of the database team at IBM for giving us these really useful tools, these SQL services. Kudos, Scott!! and all!

Cheers
Vern

Try something like this:
Select Path_Name, Get_Clob_From_File(Path_Name) "IFS File Content"
From Table (Qsys2.Ifs_Object_Statistics(Start_Path_Name => '/YourFolder/Dir2/Dir3',
Subtree_Directories => 'YES',
Object_Type_List => '*ALLSTMF')) x
Where Right(Trim(Path_Name), 5) = '.xml'
and Get_Clob_From_File(Path_Name) like '%Whatever you are looking for%'
Order By Path_Name ;

Note: GET_CLOB_FROM_FILE has to be run under Commitment Control

I know how to use grep and all, this is not another chapter in that unpublished rag, for my purposes an sql solution serves me more directly, I wanted to avoid a command line solution.

As opposed to using "grep"?

The only sensible way to do it, and if you are on IBM i and not planning to
off-platform, it's half-past time to learn grep sed tr etc. and your basic
pipeline tools.

I have XML files in a folder, I want to see which ones have a certain
value in them, such as an account code. I tried ifs_object_statistics with
start_path_name ==> set, joined to ifs_read, the path_name from
ifs_object_statistics in path_name ==>.
