BTEQ -- Enter your DBC/SQL request or BTEQ command:
show table t1;
show table t1;
*** Text of DDL statement returned.
*** Total elapsed time was 1 second.
-----------------------------------------------------------------
CREATE SET TABLE DR_DWH_LM_GH.t1 ,NO FALLBACK ,
NO BEFORE JOURNAL,
NO AFTER JOURNAL
(
a INTEGER,
b INTEGER,
c VARCHAR(6) CHARACTER SET LATIN NOT CASESPECIFIC FORMAT 'X(5)')
PRIMARY INDEX ( a );
BTEQ -- Enter your DBC/SQL request or BTEQ command:
sel * from t1;
sel * from t1;
*** Query completed. One row found. 3 columns returned.
*** Total elapsed time was 1 second.
a b c
----------- ----------- -----
1 2 xxx
BTEQ -- Enter your DBC/SQL request or BTEQ command:
alter table t1 add b compress 0;
alter table t1 add b compress 0;
*** Failure 3558 Cannot alter the specified attribute(s) for B.
Statement# 1, Info =0
*** Total elapsed time was 1 second.
BTEQ -- Enter your DBC/SQL request or BTEQ command:
alter table t1 add c compress 'a';
