Blank value coming in substring field

librasonali — Sat, 26 Feb 2022 11:22:01 GMT

Hi ,

I am getting blank values in my sbcr_ssn field when i m caluclating it from subsr_id. Can you please help me with quick fix on the substr side?? thanks !!

Also getting note in log :

NOTE: Invalid string.
NOTE: Invalid argument to function INPUT. Missing values may be generated.
NOTE: Table WORK.MEMBER_INT_CRS created, with 610173 rows and 25 columns.

FYI :Suscr_id in teradata was BIGINT i converted it into Char :

proc sql;
      connect to teradata (user="jhk" password="bhgh" server="UDWtest");
      create table member_int_crs(drop=med rx mbr_fact_mod_dt REL_CD   rename=( rel_cd1=rel_cd )) as
      select *,
             'C' as source length=1,  /* Indentify all records as CIRRUS Membership */
             'CIR'||trim(left(cust_seg_nbr)) as cust_detail_ky_char length=20,

            substr(SBSCR_ID,3,9) as sbscr_ssn length=9 ,

Your issue is not with the SUBSTR, it's with the INPUT function, so it happens here:

INPUT(REL_CD,3.) as rel_cd1

Your explicit pass-through does not deliver a column named REL_CD.

I didn't mentioned the code complete. but i m passing REL_CD, i will update the query .

my issue is my subsr_ssn are coming blank but in source subsrciber_id is populated.

This

NOTE: Invalid argument to function INPUT. Missing values may be generated.

complains about the INPUT function, so this needs to be fixed as well.

Run your code without the SUBSTR function to see which values you actually get from the DB.

I am getting below values in SBSCR_ID from table member_int_crs
Character format length 20
SBSCR_ID
2696942
488882983

and from teradata , BIGINT format length 19
SUBSCRIBER_ID
633735
201548
618887
// same type of values if in source its 633735 then in member_int_crs also its same.
and also how shd i fix this then?
NOTE: Invalid argument to function INPUT. Missing values may be generated.
for REL_CD i am getting correct value.. just the format is getting changed from char to Num

So it looks like your cast in Teradata is incorrect, as the values are changed.

no no .

SBSCR_ID

and from teradata , BIGINT format length 19
SUBSCRIBER_ID

488882983

// same type of values if in source its 633735 then in member_int_crs also its same..

issue is with sbscr_ssn , how its coming blank ? where as subs_id is coming fine .

Use

substr(left(SBSCR_ID),3,9)

and see what happens.

Casts of numeric to character are usually right-aligned.

now it's working !!
if SUBSCRIBER_ID is 633735 then subscr_ssn is 3735 , which was excepted.
