RE: Find string in multiple it's files using sql services

Vern,

You had to use the CROSS JOIN and LATERAL because you used the IFS_READ in a way that it returned multiple rows.
I used Get_Clob_From_File(Path_Name) which returns a LOB-Locator on the IFS file. LOB locators can be used like character columns. So I used it in the WHERE Condition in composition with the LIKE predicate.
If you only want to know in which file the data is located, using GET_CLOB_FROM_FILE is the easiest way (no need of any CROSS JOIN or LATERAL).
If you exactly want to see the row and the content of the row, where you find the string, your solution is the better one.

Mit freundlichen Grüßen / Best regards

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

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I know how to use grep and all, this is not another chapter in that unpublished rag, for my purposes an sql solution serves me more directly, I wanted to avoid a command line solution.

Cheers

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 ==>.
