MVA SQL Server Query Assessment question

Hi Guys
I was doing a course on MVA, Querying Microsoft SQL Server Quick Start. This question came up in the assessment:
True or False: You use the INTERSECT operator to combine results from two SELECT statements. Only rows that appear in both results sets are displayed.
I answered it as TRUE but it marked it wrong.
Am I not right??
Thanks

Hi,

Sql server query

sql server query to rearrange the rows after inserting the rows in a table

You want to re-arrange the data physically?!!! Why? I believe its something impossible other than having a clustered key(there could be some strange ways of doing it) and a thing that should not worry about. Always there is a ORDER BY CLAUSE to order your
data while retrieving

From SharePoint Content Database, Using SQL-Server Query how to fetch the 'Document GUID' based on 'Content Type'

I want to get all the documents based on content type using SQL Server Query. I know that, querying the content database without using API is not advisable, but still i want to perform this action through SQL Server Query. Can someone assist ?

You're right, it's not advisable, may result in corruption of your databases and might impact performance and stability. But assuming you're happy to do that then it is possible.
Before you go down that route, have you considered using something more safe like PowerShell? I've seen a script exactly like the one you describe and it would take far less time to do it through PS than it would through SQL.

Official documents on escaping characters in SQL Server query statements

Hi,
Are there any official documents on how to escaping special characters in SQL Server query statements? I find a lot of online resources discussing about this, but there are no definitive conclusions on:
Which characters should be escaped? (Some only said single-quote needs to be escaped, double-quote does not need. While others said both need to be escaped)
How to escape characters? (Some said using two single-quote to escape a single-quote. Others said using a backslash, etc.)
So I just wonder if there is an official document from Microsoft regarding this?
Thanks
Alan

Depends on where you're using them
If its string values then single quotes(') should be escaped by putting one more single quote before it.
If its LIKE operator you can use ESCAPE keyword or use [] to escapre special characters
see

If inside SSIS expression you can escape characters like \ " etc by adding an extra \ before the characters

Converting SQL Server Query to Oracle

Hello TechFriends,
Can any one of u please tell me equivalent of following SQL Server Query?
The same query runs in Oracle but givesa same reocrds in different order!! I want such an equivalent oracle query that gives records in same order as Sql Server does.
select
ProfValue_ProfScaleFK ProfScale,
ProfValue_Value ProfValue,
isnull(ProfValueDesc.name, ProfValue_name) ProfName
from
ProfValueDesc inner join TBL_LMS_Lang
on lang_fk = lang_pk and langid = 'en'
right outer join ProfValue
on ProfValue_ProfScaleFK = ProfScale_fk and ProfValue_Value = ProfValue_FK ;
Regards & TIA.
Anand.

If you want a specific ordering why don't you add an ORDER BY clause?

Switch from MySQL to MS SQL Server, Query not working

I'm sure there is a simple setting somewhere for this, but cannot seem to find it and really would appreciate some assistance. Have an application which uses JDBC to connect to a MySQL DB to run the following query without an issue:
SELECT * FROM users
This returns the desired results. Changed to connect to MS SQL Server 2000 using the JDBC-ODBC bridge and the same query returns no results. The problem, SQL Server wants this query instead:
SELECT * FROM [users]
I don't want to have to change queries depending on the DB, as that is supposed to be one of the advantages of JDBC. Is there a setting in MySQL (or the JDBC driver) to have it work correctly if I pass table names in []? Or is there a setting in MS SQL Server (or in the JDBC, or ODBC) to have it accept queries without the []?
Or is there a different approach that I'm missing which would avoid this whole problem?
Thanks,
Matt

I suspect your database definitions are different. It has nothing to do with your java code.
The bracket syntax is used to indicate the more standard quoted identifiers in standard SQL.
Thus you could do this in oracle and in MS SQL Server...
SELECT * FROM "users"
I suspect that the above will work for your MS SQL Server database and will not work for your Oracle database. However if you created the table in oracle and specifically used "users" (with the double quotes around the name) when creating the table then it would work.
Of course if the database definitions are different it means you must use different SQL for each. Just as if the name of the table was 'other' rather than 'users'.

SQL Server Studio Management Question

Hello,
I am creating a DB using SQL Server 2005 ( Studio Management ) and I ran a few sql queries. I ran a query and got the following error message:
Here they are with Code #s:
Msg 5074, Level 16, State 1, Line 906
The object 'CK__SavedSear__Remov__5614BF03' is dependent on column 'RemoveFromSyncTime'.
Msg 4922, Level 16, State 9, Line 906
ALTER TABLE DROP COLUMN RemoveFromSyncTime failed because one or more objects access this column.
Executing Release 2.0 Script - Part 4
Msg 245, Level 16, State 1, Line 37
Conversion failed when converting the varchar value 'Script cannot be run out of order. Last ID cannot be less than ' to data type int.
Can anyone help in letting me how to resolve this issue ?
Thanks

I've got a similar issue on SQL 2000 DB, see below;
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF__CISDetail__Ccs_O__7917DB30' is dependent on column 'CCS_OP_714_VALID_TO'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN CCS_OP_714_VALID_TO failed because one or more objects access this column.
As I've only created the table as a temporary measure to import some external data, I'm going to try removing the constriants applied and then alter the columns I need, I can then re-apply my constraints afterwards.

SQL server Query to sort the Stored procedure as text

Hi
I have a requirement as below :
Stored procedure in SQL server has some 1000 lines of code where the SP uses select, insert , update ,delete and Joins on direct tables and as well as temp tables , the requirement is to get all text code from sp which is used for either select/insert
except update and delete.
for example :
Create PROCEDURE testproc
AS
Begin
/*Statement 1*/
select id from emptable
/*Statement 2*/
select address into #empAddress from empAddresstbl
/*Statement 3*/
update a
set id = 0 from usertbl a
/*Statement 4*/
Update u
set access=0 from usertbl u
inner join permissionstbl p
on u.userid = p.userid
/*Statement 5*/
select name into #empname
from empnametbl
inner join Nametbl on
empname.id = name.id
END
for the given sample sp the output of query shld be
from emptable
from empaddresstbl
from empnametbl
join nametbl
it shld not consider the table name from update/delete and the tables used for joins in updates/delete.
This has to be achieved using SQL
Thanks,

Variable database name in SQL Server query using Oracle database link

Hi All,
I have an ApEx 4.1 app running on 11g x64 (11.2.0.1) on Windows Server 2008 x64, and I have some data integration points with a SQL Server (2005 and 2008) that I need to establish. I have configured the database link with dg4odbc and it works beautifully... I can execute queries against the SQL Server database without any problems using the database link.
However, there is a scenario where the SQL Server database name is dynamic, and I need to generate it on the fly in a PL/SQL block, and then use that in a dynamic SQL query (all of this in ApEx). This is where I run into problems... when I am querying the default database based on the ODBC connection and I don't have to specify the database name, there is no issue. But when I need to access one of several other non-default databases, I keep receiving the "invalid table" error.
This runs fine:* (note that "fv" is the name of my database link)
v_query1 := 'select "ReleaseDate" from dbo.Schedules@fv where dbo.Schedules."SchedID" = :schedule';
EXECUTE IMMEDIATE v_query1 into rel_date using schedule;
I then take that rel_date variable, convert to a varchar2 (rel_date_char), and then use it as the database name in the next query...
This returns an error_ (Error ORA-00903: invalid table name)
v_query2 := 'select "PARTNO" from :rel_date_char.dbo.ProdDetails@fv where "SchedID" = :schedule and "UnitID" = :unit
and "MasterKey" = :master and "ParentKey" = :parent';
EXECUTE IMMEDIATE v_query2 into part_number using schedule, unit, master, parent;
I have also tried using all of the following to no avail:
'select "PARTNO" from ' || :rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || @rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from @rel_date_char.dbo.ProdDetails@fv where "SchedID"...
Is there a way to do this in PL/SQL?
Thanks for any help!

Now using variables to perform the select:
SQL> declare
2 val varchar2(100);
3 c integer;
4 nr integer;
5 tabname varchar2(20) :='EMP';
6 ownr varchar2(20) :='dbo';
7 dbname varchar2(20) :='gateway';
8 begin
9 c:= dbms_hs_passthrough.open_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3;
10 dbms_hs_passthrough.parse@FREETDS_DG4ODBC_EMGTW_11_2_0_3 (c, 'SELECT count(*) FROM '||dbname||'.'|| ownr || '.'||tabname||'');
11 LOOP
12 nr:= DBMS_Hs_Passthrough.fetch_row@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
13 exit when nr=0;
14 dbms_hs_passthrough.get_value@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c,1,val);
15 dbms_output.put_line(val);
16 end loop;
17 dbms_hs_passthrough.close_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
18 end;
19 /
24576
PL/SQL procedure successfully completed.
=> instead of executing the statement using "execute Immediate" we have to use PASTHROUGH package to pass the statement to the SQL Server.

Converting MS SQL Server Query to Oracle Query

Hi There,
I've a strange problem. My project uses both MS SQL Server and Oracle server at run time. I've lot of queries which are written in MS SQL Style. Now, iam planning to write a helper class whic converts MS SQL Query to Oracle Query. Please Help me if any one has that kind of Helper with you.
Thanks And Regards,
Sasi Kanth

That is why persistence applications like Hibernate or
CMP get used for apps that will use more than one DB,
but it takes upfront planning.
If you have a set of automated unit tests that work
with SQL Server, they will be a big help in getting
your Oracle code up and running.Indeed - JUnit and Ant would be a big help here.
It sounds like you have SQL in your JSPs, that will
work against you as well if so. If you are using a
DAO pattern, this will be much easier, as you can
re-implement each DAO for Oracle.If you'd layered this app properly, you might just implement an OracleDAOFactory and be done with it. Interfaces and a DAO layer would go a long way.
This is why layering is such a good idea. It isolates changes in a smaller subset of classes.
But your problem sounds pretty big. It'd be daunting even if it were well designed.

SQL server service accounts question

We created a test SQL environment using a Technet evaluation copy of Windows Server 2012 along with an evaluation copy of SQL2012. After testing, everything is working as planned so were going to enter the product keys for both Windows Server and SQL 2012.
My question is that once we have our Server licensed we’re going to start a new domain and recreate all the user accounts but I installed SQL using a local user account I created called ”sqladmin”. Once Server 2012 is the DC in the new domain will I need to
change all the service accounts for SQL in order for it to function or can I still use the local “sqladmin” user account? If I can re-use that local account are there any downside to that? What’s the best practice in this scenario

What’s the best practice in this scenario
Hi,
You can use your sqladmin account but that wont be a good security practice. You should always follow principal of least privilege and should run SQL server with domain account having least privilege.Below link will help you in this

SQL server query without indicating server name

I am writing a query in SSIS and utilize servername everytime but it drags every time
I am authorized to work in Development area and can indicate deve server
But Senior officer ask me not to use Server name and when package goes to production query can execute without indicate server name any idea
thank you very much.
Vijay
Vijay Patel

I think you're using linked server in your queries based on your description.
While working in SSIS you dont need linked server. You'll just add connection manager to connect to your dev server and database and then use it for your tasks. Inside your query you will just reference objects using schemaname.objectname convention.
You will make servername and database name configurable by adding them as configurations (parameters in SSIS 2012 if you use project deployment). Then you will be able to pass values for configurations from outside based on variety of options like through
XML file, from SQLServer table, Environment variables etc

SQL Dev 2.1 connected to a SQL Server query

I use SQL developer to query oracle db's and from the Query result, if i right click i get the following options;
Save grid as report...
Single record view...
Count Rows...
Find/Highlight...
Export Data
However when i do this against an SQL server I only get teh following;
Save grid as report...-this is grayed out and can not be used.
Single record view...
Count Rows...
Find/Highlight...
I do not get the export option, does anyone know why? or what I can do to get it?

With SQL Developer 2.1.0 the export feature was removed for all not oracle database.
In 2.1.1 the export feature is working again so if you need to export on SQL server you should upgrade to 2.1.1.
