How about the following if the string is not too long:
BTEQ -- Enter your DBC/SQL request or BTEQ command:
show table ts2;
*** Text of DDL statement returned.
*** Total elapsed time was 1 second.
----------------------------------------------------------------
CREATE SET TABLE RGS.ts2 ,NO FALLBACK ,
NO BEFORE JOURNAL,
NO AFTER JOURNAL,
CHECKSUM = DEFAULT
(
a INTEGER,
b VARCHAR(5) CHARACTER SET LATIN NOT CASESPECIFIC)
PRIMARY INDEX ( a );
BTEQ -- Enter your DBC/SQL request or BTEQ command:
select * from ts2;
*** Query completed. 3 rows found. 2 columns returned.
*** Total elapsed time was 1 second.
a b
----------- -----
3 abcde
1 ab
2 abc
BTEQ -- Enter your DBC/SQL request or BTEQ command:
update ts2 set b =
substring(b from 5 for 1) ||
substring(b from 4 for 1) ||
substring(b from 3 for 1) ||
substring(b from 2 for 1) ||
substring(b from 1 for 1);
*** Update completed. 3 rows changed.
*** Total elapsed time was 1 second.
BTEQ -- Enter your DBC/SQL request or BTEQ command:
