I am trying to link an Access 2003 DB to tables in a SQL Server 2008 database using ODBC. When I try to link to tables that have Primary Key established I get the following error message.
" 'Pk_dbo.Batch_Claims' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not to l开发者_JS百科ong. "
Pk_dbo.Batch_Claims is the key value I see when looking at the table through SSMS. I have used Access for awhile but am somewhat new to SQL Server and connections using ODBC. Any help would be appreciated.
Thanks
You need to rename the primary key by opening your SQL Server (or Azure) database in SQL Server Management Studio. See the section "Working Around Invalid Primary Key Names" at this blog post: Linking Microsoft Access 2010 Tables to a SQL Azure Database
I have create a stored procedure what do the job for you. first we have to remove all foreign keys otherwise we can't drop the primairy key constraint. Alter that we loop to the keys drop and recreate them
Create procedure proc_changepk
As
--first drop all references
declare @sql nvarchar(max)
declare cursRef cursor for
SELECT
'ALTER TABLE [' + OBJECT_SCHEMA_NAME(parent_object_id) +
'].[' + OBJECT_NAME(parent_object_id) +
'] DROP CONSTRAINT [' + name + ']' as ref
FROM sys.foreign_keys
open cursRef
fetch next from cursRef into @sql
while @@fetch_status = 0 begin
exec(@sql)
fetch next from cursRef into @sql
end
close cursRef
deallocate cursRef
--drop and recreate primairy keys
declare @pktable table (constraintname nvarchar(255),tablename nvarchar(255),colname nvarchar(255))
insert into @pktable(constraintname,tablename,colname)
SELECT CONSTRAINT_NAME,TABLE_NAME,COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA + '.' + QUOTENAME(CONSTRAINT_NAME)), 'IsPrimaryKey') = 1
declare @pkname nvarchar(255),@tablename nvarchar(255),@cols nvarchar(255)
declare Mycurs cursor for
--maybe more than one col for primairy key
SELECT
p.constraintname,p.tablename,
STUFF((SELECT '. ' + colname from @pktable where constraintname=p.constraintname
FOR XML PATH('')), 1, 1, '') [cols]
FROM @pktable p
GROUP BY constraintname,tablename
open mycurs
fetch next from mycurs into @pkname,@tablename,@cols
while @@fetch_status = 0 begin
--drop key
set @sql='alter table ' + @tablename + ' drop CONSTRAINT [' + @pkname + ']'
print @sql
exec(@sql)
--create key
set @sql='alter table ' + @tablename + ' add CONSTRAINT [pk_' + @tablename + '] primary key NONCLUSTERED (' + ltrim(@cols) + ')'
print @sql
exec(@sql)
fetch next from mycurs into @pkname,@tablename,@cols
end
close MyCurs
deallocate MyCurs
GO
