| Posted: 05 Jun 2013 05:56 PM PDT There is a list of servers and databases kept in the catalog DB ie the DB name and connection details. This information resides in one server. I have to iterate through each server/database and connection details, establish a connection and create a login and a user in that specified database with db_datareader role. I tired using openrowset but I get the following error declare @nameout nvarchar(max)SELECT @NameOut = nameFROM OPENROWSET ('SQLNCLI','Server=Servername;TRUSTED_CONNECTION=YES;','SELECT name FROM sys.server_principals WHERE name = ''Domain\user''')IF ISNULL(@Nameout,'')=''select @Nameout as ifnameBEGINSELECT @NameOut = nameFROM OPENROWSET ('SQLNCLI','Server=Servername;TRUSTED_CONNECTION=YES;','CREATE LOGIN [Domain\user] FROM WINDOWS')select @NameOutENDCannot process the object "CREATE LOGIN [username] FROM WINDOWS". The OLE DB provider "SQLNCLI10" for linked server "(null)" indicates that either the object has no columns or the current user does not have permissions on that object.The user i have logged in definitely has permission to create login in the target server. I have also tried to link the server but still it throws me the same error. The select with openrowset seem to return the @nameout but I am unable to create a login. Please help me with this issue. |

| Posted: 05 Jun 2013 04:35 PM PDT Hi, yesterday I was working on a scenario in which I have 3 tables Table1, Table2, Table3. Table3 contain data from table1 and table2 so instead of writing two seperate queries I write in a singled query, but ir doesn't return any rows. I dont know why ?Please find the scripts below and tell me is this possible or not ?Create table #A (ID int identity primary key, Col1 varchar(10))Create table #B (ID int identity primary key, Col2 varchar(10))Create table #C (ID int identity primary key, Col3 varchar(10))INSERT INTO #ASELECT 'A1'UNION ALLSELECT 'A2'UNION ALLSELECT 'A3'INSERT INTO #BSELECT 'B1'UNION ALLSELECT 'B2'UNION ALL SELECT 'B3' INSERT INTO #CSELECT 'A1'UNION ALLSELECT 'B2'SELECT a.Col1, b.Col2FROM #A aJOIN #C C ON c.Col3 = a.Col1JOIN #B b ON b.Col2 = c.Col3DROP TABLE #ADROP TABLE #BDROP TABLE #C |
| sp_OAGetProperty @obj, 'responseText', @response OUT cannot handle large output Posted: 13 Jul 2011 08:28 PM PDT Hi All,This is quite weird, so thought you can have some ideas, please:I use HTTP POST to send and XML file to my system and to get another XML as a response.I found out that if a response XML is bigger than X characters ( haven't found yet how much is X)my response fails. I defined @response as VARCHAR(MAX) and I use SQL 2008.I know that on a server side the created XML is of a correct structure, it just fails to pull it back if it goes over the X size.Any ideas, please?Thanks. |
