[Bug 1294568] [NEW] Unable to create the Neutron network net_local because of constraints for db2

Sender: bounces@xxxxxxxxxxxxx
Public bug reported:

CREATE TABLE subnets (tenant_id VARCHAR(255),id VARCHAR(36) NOT NULL,
name VARCHAR(255),network_id VARCHAR(36), ip_version INT NOT NULL, cidr
VARCHAR(64) NOT NULL,gateway_ip VARCHAR(64),enable_dhcp SMALLINT,shared
SMALLINT,ipv6_ra_mode VARCHAR(16), ipv6_address_mode VARCHAR(16),PRIMARY
KEY (id), FOREIGN KEY(network_id) REFERENCES networks (id),CHECK
(enable_dhcp IN (0, 1)), CHECK (shared IN (0, 1)), CONSTRAINT ipv6_modes
CHECK (ipv6_ra_mode IN ('slaac', 'dhcpv6-stateful',
'dhcpv6-stateless')),CONSTRAINT ipv6_modes CHECK (ipv6_address_mode IN
('slaac', 'dhcpv6-stateful', 'dhcpv6-stateless')))


for db2, this fails because the name ipv6_modes is used twice for a contraint name.  In db2, A constraint-name must not identify a constraint that was already specified within the same CREATE TABLE statement. (SQLSTATE 42710).

Title:
  Unable to create the Neutron network net_local because of constraints
  for db2

Status in OpenStack Neutron (virtual network service):
  New

Bug description:
  CREATE TABLE subnets (tenant_id VARCHAR(255),id VARCHAR(36) NOT NULL,
  name VARCHAR(255),network_id VARCHAR(36), ip_version INT NOT NULL,
  cidr VARCHAR(64) NOT NULL,gateway_ip VARCHAR(64),enable_dhcp
  SMALLINT,shared SMALLINT,ipv6_ra_mode VARCHAR(16), ipv6_address_mode
  VARCHAR(16),PRIMARY KEY (id), FOREIGN KEY(network_id) REFERENCES
  networks (id),CHECK (enable_dhcp IN (0, 1)), CHECK (shared IN (0, 1)),
  CONSTRAINT ipv6_modes CHECK (ipv6_ra_mode IN ('slaac',
  'dhcpv6-stateful', 'dhcpv6-stateless')),CONSTRAINT ipv6_modes CHECK
  (ipv6_address_mode IN ('slaac', 'dhcpv6-stateful',
  'dhcpv6-stateless')))

  
  for db2, this fails because the name ipv6_modes is used twice for a contraint name.  In db2, A constraint-name must not identify a constraint that was already specified within the same CREATE TABLE statement. (SQLSTATE 42710).
