I am planning to add some new columns to an existing sql server 2012 table. I know that I need to use the alter statement to accomplish this goal. However my questions is the location of where I want to add the new columns to the table. It would make more sense to add the new columns to the middle of the table since these columns have a similar meaning as other columns in the middle of the table.
However is it better to add these new columns at the end of the table? I am asking this question since I am thinking I might need some sql to move the values of existing columns and values around?
Thus is it better to add new columns to a table in the middle of the table, at the end of the table, or at the end of the table? If so, why one location is better than another location?
I am trying to insert a single row in Temp table #InventoryItems . The temp table is mentioned in a curosor childcur_inventory. While looping through the cursor I have mentioned nested if else condition . In the Else condition where I have mentioned PRINT "Hello World" I want to insert a single row in the temp #InventoryItems. I trying to use Select Top 1 but the cursor is looping indefinitely trying to insert multiple record
I want to insert only one record with null values.
DECLARE childcur_inventory CURSOR FOR SELECT Structure_Number, State, Neighbor_State, Border_Bridge_Structure_Number FROM #InventoryItems
OPEN childcur_inventory
FETCH childcur_inventory INTO @Structure_Number, @State, @Neighbour_State, @Border_Bridge_Structure_Number

I need to add a join in my select query depending upon a variable @LoggedUser. the Join is to be there if @loggedUser is 1 else i do not need it. Currently I am using two different queries one with join and one without it under If (@LoggedUser check).
the join is like -
JOIN (SELECT CAST(CONVERT(VARCHAR(8),Analyst_Effective_date , 1) AS DATETIME) Analyst_Effective_date
FROM Users us (NOLOCK) JOIN Primary_Analysts (NOLOCK)
ON User_Count_Id = Analyst_Id_fk
WHERE User_Count_Id in ((SELECT VALUE FROM dbo.fParseString(@Analyst, ',')) )) Ana
ON dep.Departure_Code = Ana.Primary_Analyst_Departure_Code_fk
)
Any way that the join can be added conditionally in the query so i do not have to write the whole code again for one join.
I have a data output with many rows. In order to group things with flags, I do this in excel using 2 formulas which *** a flag of 0 or 1 in 2 new columns.
This takes a long long time as I have hundreds of thousands of rows and wondered of I could do it in sql?
Its transact SQL and the formulas I use in excel are:
=IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2)*($C$2:$C2>=C2-1/24)*($C$2:$C2< C2+1/24))> 1,0,1)
=IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2))>1,0,1)
How I can do this in sql??
The columns above do not relate to the actual columns I use, just an example.
I have a situation that I need to add a field to a table over linked server. The specifications of this is dynamic and it is being done in TQL / Stored procedures and this can not change. My code is generating the statement just fine and if I copy paste it to a new SSMS window and execute it WORKS.. The problem is I need to dynamically generate the statement (I am doing that just fine, I THINK). THEN I need to execute the statement IN THE SPROC, this part is not working.
Here is the code:
SET @AlterSQL = @DestinationServerName + '.[' + @DestinationDBName +'].' + @DestinationSchemaName + '.sp_executesql N'' ALTER TABLE '
+ @DestinationTableName + ' ADD ' + @TempColumn + ' int' + CHAR(39)
The above Creates this when I expose it via a PRINT statement:
addb15.[FSParallel].dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int'
After I create the statement I use:
EXEC @AlterSQL
And this returns the following error:
Msg 2812, Level 16, State 62, Procedure ETLDynamicImport, Line 244
Could not find stored procedure 'FSParallel.dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int''.
<hr noshade size='1' width='250' color='#BBC8E5'>
I have made this defination for a stored procedure:
PROCEDURE EP_Conterbalances
@Start_Date_For_Totals_Date DATETIME,
@EmpFilterAddDuty VARCHAR(500),
@CounterBalanceType_id INT,
@dateFrom DATETIME,
[Code] .....
The value of @EmpFilterAddDuty could be:
'SELECT E.EmployeeID FROM dbo.EmployeeGroupMapToEmployee E, dbo.Per_Budget B WHERE E.EmployeeID = B.PER_PERSONAL_ID AND B.PEB_Budget_id = 243 AND E.EmployeeGroupID IN (SELECT H.Id FROM dbo.EmployeeGroup H WHERE H.InstitutionsId = 22) GROUP BY E.EmployeeID '
If i Replace @EmpFilterAddDuty with this in a QUERY, it gives me the expected result, but if i try to execute the stored procedure.:
DECLARE@return_value int
EXEC@return_value = [dbo].[EP_Conterbalances]
@Start_Date_For_Totals_Date = N'20120831',
@EmpFilterAddDuty = 'SELECT E.EmployeeID FROM dbo.EmployeeGroupMapToEmployee E, dbo.Per_Budget B
[Code] .....
I get this error code:
Conversion failed when converting the varchar value 'SELECT E.EmployeeID FROM dbo.EmployeeGroupMapToEmployee E, dbo.Per_Budget B WHERE E.EmployeeID = B.PER_PERSONAL_ID AND B.PEB_Budget_id = 243 AND E.EmployeeGroupID IN (SELECT H.Id FROM dbo.EmployeeGroup H WHERE H.InstitutionsId = 22) GROUP BY E.EmployeeID ' to data type int.
I really do not understand why SQL 2012 tries to convert the value to an int, and I want to know how to pass the text string.

1) Create linked servers on all group members pointing to all other servers in the group, with names matching the hostnames they represent.
2) Ensure suitable credentials (or 'current context' impersonation) for linked servers. Also: Enable RPC and RPC OUT
3) Run the DDL code below.
4) Schedule hadr_replicate_queue on [master] to run as often as you want initial syncs to occur. Every 5-10 minutes is plenty for most purposes.
5) Connect to an availability group listener and call CREATE DATABASE :)
I use a slightly more extended version of this code at home to do things like permissions synchronization across replicas - I essentially allow applications to install direct to an availability group replica and then have all the relevant objects replicate to other nodes. I don't really like going through manually and doing things, even though there's an AddIn from SQLSkills for management studio - it still requires manual intervention.
The main use I have for this at home is that I'm using the Azure pack, and want to automatically ensure that my newly created 'SQL Server Cloud' databases are highly available, plus it means when I install a non-alwayson aware product it doesn't require any extra work afterwards to allow failover to another machine.

I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'
WHERE [Acct_Num_CH] IS NOT NULL
WHILE @@ROWCOUNT > 0
BEGIN
SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'
WHERE [Acct_Num_CH] IS NOT NULL
END
SET rowcount 0
These separate COUNT queries are very fast:
SELECT COUNT(id) as viewcount from location_views WHERE createdate>DATEADD(dd,-30,getdate()) AND objectid=357
SELECT COUNT(id)*2 as clickcount FROM extlinks WHERE createdate>DATEADD(dd,-30,getdate()) AND objectid=357
But I want to add the COUNT statements, so this is what I did:
select COUNT(vws.id)+COUNT(lnks.id)*2 AS totalcount
FROM location_views vws,extlinks lnks
WHERE (vws.createdate>DATEADD(dd,-30,getdate()) AND vws.objectid=357)
OR
(lnks.createdate>DATEADD(dd,-30,getdate()) AND lnks.objectid=357)
Turns out the query becomes immensely slow. There must be something I'm doing wrong here which results in such bad performance, but what is it?

View 4 Replies View RelatedI am getting inconsistent results when BULK INSERTING data from a tab-delimited text file. As part of my testing, I run the same code on the same file again and again, and I get different results every time! I get this on SQL 2005 and SQL 2012 R2.
We have an application that imports data from a spreadsheet. The sheet contains section headers with account numbers and detail rows with transactions by date:
AAAA.1234 /* (account number)*/
1/1/2015 $150 First Transaction
1/3/2015 $24.233 Second Transaction
BBBB.5678
1/1/2015 $350 Third Transaction
1/3/2015 $24.233 Fourth Transaction
My Import program saves this spreadsheet at tab-delimited text, then I use BULK INSERT to bring the data into a generic table full of varchar(255) fields. There are about 90,000 rows in each day's data; after the BULK INSERT about half of them are removed for various reasons.
Next I add a RowID column to the table with the IDENTITY (1,1) property. This gives my raw data unique row numbers.
I then run a routine that converts and copies those records into another holding table that's a copy of the final destination table. That routine parses though the data, assigning the account number in the section header to each detail row. It ends up looking like this:
AAAA.1234 1/1/2015 $150 First Purchase
AAAA.1234 1/3/2015 $24.233 Second Purchase
BBBB.5678 1/1/2015 $350 Third Purchase
BBBB.5678 1/3/2015 $24.233 Fourth Purchase
My technique: I use a cursor to get the starting RowID for each Account Number: I then use the upper and lower RowIDs to do an INSERT into the final table. The query looks like this:
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericTable
WHERE RowHeader LIKE '____.____%'
Results look like this:
But every time I run the routine, I get different numbers!
Needless to say, my results are not accurate. I get inconsistent results EVERY TIME. Here is my code, with table, field and account names changed for business confidentiality.
TRUNCATE TABLE GenericImportTable;
ALTER TABLE GenericImportTable DROP COLUMN RowID;
BULK INSERT GenericImportTable FROM 'SERVERGeneralAppnameDataFile.2015.05.04.tab.txt'
WITH (FIELDTERMINATOR = ' ', ROWTERMINATOR = '', FIRSTROW = 6)
ALTER TABLE GenericImportTable ADD RowID int IDENTITY(1,1) NOT NULL
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericImportTable
WHERE RowHeader LIKE '____.____%'
Hi,
Is there something equivalent to the MINUS in ORacle ?
Or a workaround ?

I have two tables CarType & Cars. Table CarType has a column CarTypeId which is the primary key (int, identity). Table Cars includes a column CarTypeId (int) which is a foreign key into the CarType table.Now I am trying to build a list of all those CarTypeId entries (from the CarType table) for which there are no Cars (i.e. there is no corresponding entry in the Cars table).I read that there is an SQL "MINUS" keyword that you can use like this:
SELECT CarTypeId FROM CarTypeMINUSSELECT CarTypeId FROM Cars..So if CarType contains records with the keys {1, 2, 3, 4, 5} and Cars contains records with the foreign keys {2, 4} (using set notation), your result should be the set {1, 3, 5}. (Note: I have tried alternate versions of this where I selected the DISTINCT CarTypeId entries from Cars, and where I sorted them; results same in both cases).I tried it in SQL Server 2005 Express. The result is just {1, 2, 3, 4, 5}.
Is the MINUS capability supported by SQL Server? I know that there are all sorts of different SQL dialects & implementations and that SQL has evolved & transmutated over the years; perhaps they opted to leave this out of SQL Server..

Employees can be at multiple locations during the two weeks. They can work at one location, stop working there, start working somewhere else, and then maybe go back to their old location. There are duplicate records here as each employee can be at the same location multiple times during the two week period. What I need to capture is the actual start and end date of an employee at each location for each 'assignment'. An assignment is defined as a continual period of employment at a location with gaps of no less than 4 days - if there is a gap of more than four days then that is classed as a new assignment.

Basically if the type code is 1 one then move the data to column phone1, if the type is 2 then move it to column phone2.
This would be fairly simple if we always have type codes 1 and 2. But sometimes we can have type 1 and not type 2, or we could have type 2 and not type1.
Right now we only have 2 type codes. But, in the future we could be adding a 3rd type. So that would add a 3rd column (phone3).
Below is my code that I have written. I move the data into a temp table then list it. I am thinking of making this a view to my table. It works just fine. My question is, is there a better and more efficient way of doing this?
CREATE TABLE #Contacts (
id INT PRIMARY KEY,
phone1 VARCHAR(15),
phone2 VARCHAR(15)
)
-- Insert the records for type 1
INSERT INTO #Contacts
SELECT id,
phone_num,
NULL
FROM test1
WHERE type_code = '1'
-- Insert the records for type 2, if the id does not exist for type 1
INSERT INTO #Contacts
SELECT id,
NULL,
phone_num
FROM test1
WHERE NOT EXISTS (
SELECT 1
FROM #Contacts
WHERE #Contacts.id = test1.id
)
AND test1.type_code = '2'
-- if the id has both type 1 and 2, update the phone2 column with the data from type 2
UPDATE #Contacts
SET phone2 = test1.phone_num
FROM #contacts
JOIN test1 ON test1.id = #Contacts.id
WHERE type_code = '2'
SELECT id, phone1, phone2
FROM #Contacts
DROP TABLE #Contacts
How I could accomplish taking several rows for one account and concatenate them into one row, for example I have account_num, invoice_date, transaction_num, msg_counter,Message_2,SQL_LAST_UPDATE the special characters &,",!,$,# are used to determine the Message_2 content for a given account_number that are supposed to be together.
I am needing to put all of that accounts_messages in one row to display on a report, the table I am pulling this data from only has a varchar(40) for the message_2, a proprietary source so can't change that length, "I'VE ASKED THEM TO DO THIS, AND THEY REFUSED". So my only option is to insert this data into my table and create a single Message_2 for that account.

In a t-sql 2012 sql script, I have the following script, that only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value or 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?

JOIN TST.dbo.LockCombination LKC ON LK.lockID = LKC.lockID

3 1 TypeB
4 NULL TypeA
5 NULL TypeB
6 26 TypeC
7 NULL TypeD
8 NULL TypeD
I would like to return all the rows except where Key=1 and Key=3 because those rows together meet the criteria of Type='TypeA'/Key2=NULL and does have a corresponding row with Type='TypeB'/Key1=Key2.
