Allow standard SQL syntax: ALTER TABLE ALTER [COLUMN] <col> SET DEFAULT
<default>
---------------------------------------------------------------------------------
Key: DERBY-4013
URL: https://issues.apache.org/jira/browse/DERBY-4013
Project: Derby
Issue Type: Improvement
Components: SQL
Affects Versions: 10.4.2.0, 10.4.1.3, 10.3.3.0, 10.3.2.1, 10.3.1.4,
10.2.2.0, 10.2.1.6, 10.1.3.1, 10.1.2.1, 10.1.1.0, 10.0.2.1, 10.0.2.0
Reporter: Dag H. Wanvik
Priority: Minor
Presently, the Derby syntax is ALTER TABLE ALTER [COLUMN] <col> [WITH] DEFAULT
<default>.
The "SET" keyword is not accepted, only an optional "WITH". It would be good to
accept the standard syntax here as well.
Cf. SQL 2003, section 11.12 <alter column definition> and section 11.13 <set
column default clause>.
Repro on trunk:
$ java org.apache.derby.tools.ij
ij version 10.5
ij> connect 'jdbc:derby:wombat;create=true';
ij> create table t(i int default 0, j int);
0 rows inserted/updated/deleted
ij> alter table t alter column j with default 1;
0 rows inserted/updated/deleted
ij> insert into t values (default, default);
1 row inserted/updated/deleted
ij> select * from t;
I |J
-----------------------
0 |1
1 row selected
ij> alter table t alter column j default 2;
0 rows inserted/updated/deleted
ij> insert into t values (default, default);
1 row inserted/updated/deleted
ij> select * from t;
I |J
-----------------------
0 |1
0 |2
2 rows selected
ij> alter table t alter column j set default 3;
ERROR 42X01: Syntax error: Encountered "set" at line 1, column 30.
