RE: Built-in %split RPGLE function

We've Scott's gettok() procedure in our standard string handling service
program for so long that except for the missing % I would forget that it
is not a built in function.

Birgitta has supplied an example. Others have mentioned Scott's RPG
Service
routines.

Both - I strongly suspect - will be faster than the SQL approach and
certainly
easier to understand and modify.

I love these "so simple" SQL responses that end up being more code
(and in my opinion) less obvious than RPG ... <grin>

it is so simple with Sql, just create below function(you can even
create it on green screen) and you will accomplish what you need.

CREATE FUNCTION Qgpl.SPLIT (@Data VARCHAR(32000), @Delimiter
VARCHAR(5))

RETURNS TABLE (ID INT, VALUE VARCHAR(256))


LANGUAGE SQL

DISALLOW PARALLEL

DETERMINISTIC

NOT FENCED

RETURN

WITH CTE_Items (ID,StartString,StopString) AS

(SELECT 1 AS ID, 1 AS StartString,

LOCATE(@Delimiter, @Data) AS
StopString

FROM SYSIBM.SYSDUMMY1


WHERE LENGTH(@Delimiter)>0 AND
LENGTH(@Data)>0


UNION ALL


SELECT ID + 1,StopString + LENGTH(@Delimiter)


,LOCATE(@Delimiter, @Data, StopString +
LENGTH(@Delimiter))

FROM CTE_Items


WHERE StopString > 0)


SELECT ID, SUBSTRING(@Data,StartString,

CASE WHEN StopString=0 THEN LENGTH(@Data)


ELSE StopString-StartString

END)

FROM CTE_Items


This will split your record as rows and then you just have to
populate your array from each

row, be aware that the function should receive two parameters,
first
parms should be your

delimited record as one big string and second parms should be the
delimiter in your case

it will be a comma. Hope this help.

Subject: Built-in %split RPGLE function

Hello all

Is there a built-in RPGLE function to split a comma (or other
delimiter) separated record into an array?

I know it can be done by creating a suitable procedure - I'm just
being lazy.

TIA
Gad
