FK Constraints Failing on Merge in MS-SQL
-----------------------------------------
Key: DDLUTILS-50
URL: http://issues.apache.org/jira/browse/DDLUTILS-50
Project: DdlUtils
Type: Bug
Environment: WinXP Pro, SQL Server 2000, Java 1.4.2
Reporter: Colin Ritchie
Assigned to: Thomas Dudziak
Re-running the writeSchemaToDatabase task on an existing MS-SQL database causes
errors on all the foreign-key nodes, reporting the error "There is already an
object named 'name' in the database".
Snippet of my schema:
<table name="oci_schedules">
<column name="schd_m_id" primaryKey="false" required="true" type="INTEGER"
default="0" autoIncrement="false"/>
<foreign-key foreignTable="oci_schedule_modes">
<reference local="schd_m_id" foreign="schd_m_id"/>
</foreign-key>
</table>
<table name="oci_schedule_modes">
<column name="schd_m_id" primaryKey="true" required="true" type="INTEGER"
autoIncrement="true" description="auto_increment"/>
</table>
Error:
[ddlToDatabase] SQL Command ALTER TABLE "oci_schedules"
[ddlToDatabase] ADD CONSTRAINT
"oci_schedules_FK_schd_m_id_oci_schedule_modes" FOREIGN KEY ("schd_m_id")
REFERENCES"oci_schedule_modes" ("schd_m_id") failed with [Microsoft][SQLServer
2000 Driver for JDBC][SQLServer]There is already an object named
'oci_schedules_FK_schd_m_id_oci_schedule_modes' in the database.
I have tried this using the open source JTDS 1.1, with the same error message.
I have also tried specifying the foreign key name in the XML node, with the
same result.
