T-SQL (SS2K8) :: Insert Subset Of Self-referencing Table Into That Table
Mar 19, 2015
IF OBJECT_ID('tTable') IS NOT NULL
DROP TABLE tTable
GO
CREATE TABLE tTable
(nRow_IdINTEGER IDENTITY NOT NULL PRIMARY KEY,
nParent_IdINTEGERNULL,
[Code] ....
gives:
nRow_Id nParent_Id cGroup cValue
----------- ----------- ------- ------
1 1 One A
2 1 One B
3 2 One C
I want to insert a copy of this data, but w/ group = 'TWO', so the table will contain the additional rows
4 4 Two A
5 4 Two B
6 5 Tow C

We are in the conversion process of making the database ints.This is a change from a guid PK to an integer based PK that uses an int Identity. The program still uses the guid, and we are trying to map that guid to the databases int.We insert using TVPs passed from code. Since the identity is being set upon insert I have three things to accomplish:
1) Insert all the data into the dbo table
2) Update the parent Id in the table
3) Pass the SetsId guid, Sets_Id int, ParentSets_Id int back to the program
This is a high transaction table that will have a lot of records (millions).
--Sample table creation. There is a FK between Sets_Id to ParentSets_Id, Clustered PK on the Sets_Id
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[JSets]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[JSets](
[SetsID] [uniqueidentifier] NOT NULL,
[Sets_Id] bigint Identity (1,1) NOT NULL,
[code]...

table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process:
1. get data from an existing view and insert in temptable
2. truncate/delete contents of table1
3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted)
4. insert data in table2 which are not yet present (comparing ID in t2 and temptable)
5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.

I am trying to move data from one table to the another (staging to real time) in a stored procedure.
There are no indexes or primary keys on the target table and it is still taking ages to execute it (30 minutes approx.). There are no defaults, no constraints as well. There is one identity int column though.
There are some 500000 odd rows in the target table.
I am using the
Insert into..
Select from..
method.

I have a table called ADSCHL which contains the school_code as Primary key and other two table as
RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.
I tried using Merge Update function not sure if this is going to work.
Update dbo.ADSCHL
SET dbo.ADSCHL.SCHOOL_CODE = FD.SCHOOL_Code
FROM dbo.ADSCHL AD
INNER JOIN TESTCEP FD
ON AD.SCHOOL_NAME = FD.School_Name

I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.
Any ideas on what I am doing wrong here?

I've 2 tables as follow, --> Full script and data as attachment, Scripts.zip
CREATE TABLE [dbo].[myMenuCollection](
[menuCollection_idx] [int] NOT NULL,
[parentID] [int] NULL,
[code]....
You can see - User select 3 Menu, which is the Menu Id is 1, 4, 10.If the Parent Id for Menu is 0, there is 1 record only to insert. If the Parent Id for Menu != 0, we've to make sure the Insert statement will insert the Parent Menu automatically
Based on Photo Above, there's 3 Menu is selected. But, in back-end - Insert statement will insert 4 record. Please see Menu Id = 10. The Parent Id = 9. So, we need to insert Menu Id = 9 automatically into myInsertedMenu table

I'm beating my head up against a wall here. I have one very LARGE table called op_hist.
CREATE TABLE [dbo].[op_hist] (
[op_trnbr] [int] NOT NULL ,

[op_date] [smalldatetime] NULL ,
[op_act_setup] [decimal](38, 10) NULL ,

[op_qty_comp] [decimal](38, 10) NULL ,
[op_wkctr] [varchar] (80) ,
[op_part] [varchar] (30)
)
I need to be able to sum items grouped by op_wkctr and op_part and op_date. Here's my latest version which of course does not work.
SELECT op_wkctr, pcs, hrs.b
FROM
dbo.op_hist
INNER JOIN
(
SELECT op_part, SUM(op_qty_comp) as pcs
FROM dbo.op_hist
where op_type='BACKFLSH'
group by op_hist.op_part
UNION ALL
SELECT op_part, SUM(op_act_setup + op_act_run) as b
FROM dbo.op_hist
where op_type='LABOR'
group by op_hist.op_part
) AS hrs
ON op_hist.op_part = hrs.op_part
where (op_wkctr = 'P-P36' or op_wkctr = 'P-P38' or op_wkctr='P39') and op_date ='10/22/07'
Help me oby one - you're my only hope.

Hi,I was wondering if you guys have any nth script to reads from tableand outputs into a temp table subset of records. There was a nth toolI used to use it was GROUP1 which was written in C and it used to bevery fast on nth -in a flat file. In this program we used to pass fewparamaeters. For example if I want 30,000 records from the file of500,000. The function seams to work something like this. you dividethe 30,000 records of 500,000 which will result with .090909090909.Now we would pass only the first 7 digit (0909090) as parameter thatwould nth the file down to 30,000 records. This function allwaysworked whichever number you use as long as the read file is largerthan output fileI like to use the similar concept in Sql Server and I was wondering ifanyone has any script to do this or how to go about this?Thank you. I appreciate your feedbackagron

Hi all,
I’ve a table with production objects, and another with possible items composition of the object. I need to count how many occurrences of each standard composition appears:
Table PROD:
PROD_ID COMPONENT TYPE
--------- ----------- -----
1 AAA X1 BBB Y2 AAA X3 BBB Y4 AAA Y5 AAA X5 BBB YTable ITEM_COMPITEM_ID COMPONENT TYPE-------- --------- -----7 AAA X7 BBB Y8 AAA X9 BBB Y
The result should be:
ITEM_ID OCCURRENCES-------- ----7 28 19 1
Table PROD have millions of rows, my way is too slow (I’ve a loop where each PROD object are separately queried against the ITEM_COMP), some have an idea for a most efficient way?

DB design question
I have multiple tables with information about a user. The tables are Roles, Users, Groups and Profiles.
For a user session I need information from all those tables. Would it be better to make a table called UserSession and collect the necessary data from the above mentioned tables and stick them in one the UserSession table or should I just write a query that goes out and gets the data from the different tables.
What is better practice and what is faster?

select A.* from A inner join B on... ..... inner join C......where left(A.id, 3) = B.sid.... AND B.num between 100 and 200).
How can I do this in SSIS? Which data flow item I may need?

Hi,
I'm using MS SQL 2005 Express.
CREATE TABLE Folder (
iD int NOT NULL IDENTITY (1, 1) PRIMARY KEY,
folderName varchar(50) NOT NULL,
parentFolderID int NULL
FOREIGN KEY REFERENCES Folder (iD)
)
GO
if I add an ON DELETE CASCADE to the foreign key, then i get an error... which is annoying. If a folder is deleted, then all its sub-folders should also be automatically deleted.
The error is: 'Introducing FOREIGN KEY constraint 'FK__Folder__parentFo__7D78A4E7' on table 'Folder' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.'
Anyone got any advice?

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.

I have an Employee table that has
EmployeeID (PK)
SupervisorID (which is really just another EmployeeID)
..random junk...
Now that part makes sense, everyone gets one and only one boss.
Their boss can change, and therefore the SupervisorID would be updated.
Now I have an EmployeeEvals table that has quarterly evaluation data.
I want to relate these two tables.
Eval table has
EvalID (PK)
ReviewedEmployeeID (the one being evaluated)
SupervisorID (the one doing the evaluation)
Now I need to link this back to the employee table (at least I think I do).
So I would want to relate it by the ReviewedEmployeeID going back to EmployeeID in the employee table and I also want the SupervisorID to do the same...
But of course that won't work because that would seem to indicate that a single record on the Employees table (say EmployeeID 55) should have a matching (or could) record in the Eval table that would look like
EvalID: 12345
ReviewedEmployeeID: 55
SupervisorID: 55
which of course wouldn't happen as an employee wouldn't evaluate themself.
How do I handle the relationships for this properly?
Do I just not link the SupervisorID back to anything?

I've recently finished an application for a small company with perhaps two hundred employees. Each employee was set up in a Users table in the database, against which application logins were processed.
For just about every other table in the database, other than pure lookup tables, we created columns to indicate the user who created the entry, and the user who last modified the entry. This was done using FK references back to the Users table. Each table contains two references back to the Users table, and there are over 150 tables now that follow this scheme. At first I was not concerned, other than the fact that it makes a visual picture of the data model look very confusing (almost every table has a pair of links back to the Users table), until I encountered an issue where I could no longer delete from the Users table. Upon surpassing 253 FK references to Users, I can no longer delete users, as the Query Optimizer can't complete the query.
Now, all of that so far is really not a big deal. Deleting users was never my intent anyway. The only real question I have is whether this is the standard way of maintaining history for table records. Have others used this method? Is there a better way?

Setup:
Using SQL 2005
TableA
ID INT PK
Name VARCHAR
RefID FK
ID Name RefID
1 Test1 <NULL>
2 Test1a 1
3 Test1b 1
4 Test1b1 3
5 Test1b1a 4
CREATE TRIGGER Update_ID
ON TableA INSTEAD OF UPDATE
AS
IF UPDATE(ID)
BEGIN
DECLARE @old_ID INT
DECLARE @new_ID INT
SELECT @old_ID = ID FROM DELETED
SELECT @new_ID = ID FROM INSERTED
UPDATE TableA
SET ID = @new_ID
WHERE ID = @old_ID
UPDATE TableA
SET RefID = @new_ID
WHERE RefID = @old_ID
END
SPROC:
UPDATE TableA
SET ID=6
WHERE ID=2
RefID is the FK to ID
ID is also the PK to another table and has the relationship use cascading Delete and Update.
Problem:
"The UPDATE statement conflicted with the SAME TABLE REFERENCE constraint"
This is referring to the first UPDATE of the Trigger.
It was my understanding that Instead Of checks the constraints after it is all done yet it errs with the first Trigger UPDATE.
I was expecting to overcome the self-reference constraint issue by using Instead Of and with the first Trigger UPDATE, change the ID(PK) and then change the RefID(FK) with the second Trigger UPDATE.
Once that was done, it should have not had any constraint problems. Thoughts?
Thanks, Nathan
