SQL Server 2012 :: Generating Hex On Insert?
Aug 4, 2014
I am trying to generate a hex value automatically at time of insert. The column used for the hex # is an identity column. I am getting an error that the trigger fails because the field doesn't accept nulls. My guess is that the identity column is not populated yet.
Below is the table and trigger.
CREATE TABLE [dbo].[scancode](
[scancode_id] [int] IDENTITY(1,1) NOT NULL,
[scancode] [varchar](50) NOT NULL,
[parent_object] [varchar](150) NOT NULL,
[parent_object_id] [int] NOT NULL,
[Created] [datetime] NOT NULL,
[code].....

I have installed SQL Server 2012 Express edition SP1 in my system. I have created a database in the instance. Now when I try to generate scripts of tables using Right click on database > Click on Task > Click on Generate Scripts, it is showing Error in Action 'Getting the list of objects from <database>'.

I'm trying to set up a SQL Alert to run when a Failed login error is generated. For whatever reason, I can't seem to get this working. I have it set up to run on error 18456 (Failed login), I have the server set to log failed login attempts and I can see the entry in the log file, but the alert never occurs. Basically, I want a way to detect when someone is trying to hack into my database using a brute force approach.

I am attempting to create a snapshot replication publication.
When the snapshot is generated, any table that consists of all numeric columns creates a script with SET ANSI PADDING OFF
I googled around a bit and found that if a DDL trigger is in place on the database, it will cause this to happen.
I dropped the triggers, re-created the publication and subscription, same thing.

Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?
Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.
I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.

I wonder if it possible to move data from tables on a linked server to a "normal database"?
Name linked server: Covas
Name table on linked server: tblCountries
Name field: cntCountryName
Name "normal" database: CovasCopy
Name "normal" table: Countries (or dbo.Countries)
Name "normal" field: Country
This is just a test setup. I figure that if I get this working the rest will be easier.
My current query:
select * from openquery(COVAS,'
INSERT INTO CovasCopy.dbo.Countries(Country)
SELECT cntCountryName FROM db_covas.tblCountries;')

I have a query which is primarily a victim of blocking and a blocker itself for other queries. I studied the plan for this and it shows a 42% cost on CI insert operation. The insert is happening on a table (Table A) that has a PK. This PK is not a running number. It is also a business key (primary key) in another master table (Table B).
My understanding is that the cost is heavy because -
1, this PK is not an incremental number. It could be any number not in a sequence.
2. while inserting into CI, there must be a scan happening to find out the location where the index will be inserted.
How can I reduce the cost?
1. Should I go for partitioning of this table Table A? I am trying to do this but I am not able to find any suitable partition key looking at the JOINS and filter clauses where this table is being used in the applicaiton.
2. Should I introduce a surrogate key (running number) as a primary key so that CI is faster ?

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?
UDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number
JOIN TST.dbo.Lock LK ON LKR.lockID = LK.lockID
JOIN TST.dbo.LockCombination LKC ON LK.lockID = LKC.lockID
WHERE LKC.seq = 2
A normal select statement looks like the following:
select * from TST.dbo.Locker LKR
JOIN TST.dbo.Lock LK ON LKR.lockID = LK.lockID
JOIN TST.dbo.LockCombination LKC ON LK.lockID = LKC.lockID
where LKR.number in (000,001,1237)
In case you need the ddl statements for the tables affected here are the ddl statements:
CREATE TABLE [dbo].[Locker](
[lockerID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[serialNumber] [varchar](20) NULL,
[type] [varchar](3) NULL,
[locationID] [int] NULL,

I am using an aggregate with the OVER clause.Running the script is fast less than 1 second but when I say insert into a temp table the execution plan is very different at it take 8 seconds.I have attached the execution plans. Also the Statistics IO, Time messages. I am using SQL Server 2014 with backward compatibility to 2008 R2.
if (select OBJECT_ID('tempdb..#MM')) is not null drop table #MM
CREATE TABLE #MM ([MyTableID] [int], [ParticipantID] [int], [ConferenceID] [nvarchar](50), [Points] [money], [DateCreated] [datetime], [StartPoints] [money], [EndPoints] [money], [LowPoints] [money], [HighPoints] [money])
insert into #MM ([MyTableID], [ParticipantID], [ConferenceID], [Points], [DateCreated], [StartPoints], [EndPoints], [LowPoints], [HighPoints])

CREATE TABLE #MyTable
(
Teams VARCHAR(10),
StartDate DATETIME,
Count INT
)
INSERT INTO #MyTable (Teams,StartDate,Count)
SELECT 'Team A', '01/01/2014',10
[Code] ....
'Team A' Has No records for '01/02/2014' and '01/03/2014' so I need to insert values of '01/01/2014' StartDate for Team A for the missing dates
So 'Team A' will now have 3 records
Team A2014-01-01 00:00:00.00010
Team A2014-01-02 00:00:00.00010
Team A2014-01-03 00:00:00.00010
'Team B' Has No records for '01/03/2014' so I need to insert values of '01/02/2014' StartDate for Team B for the missing date
So 'Team B' will now have 3 records
Team B2014-01-01 00:00:00.00030
Team B2014-01-02 00:00:00.00040
Team B2014-01-03 00:00:00.00040
As for 'Team C' we have values for all 3 dates, no inserts needed.

Given a Table1 with two columns 'Name' with some N rows of data and another Table2 with one column 'SeqNo' with N rows, each of which contains a unique integer which can be ordered monotonically, I want to do an INSERT into some Table3 with two columns 'Name' and 'SeqNo' such that each INSERT'd row gets one of the unique integers.
E.g. -
Table1 contains 'Fred','Tom','Mary','Larry'
Table2 contains 6000978,6000979,6000980,6000981
INSERT INTO Table3
SELECT Table1.Name
Table2.SeqNo
FROM Table1
And I want to get Table3
'Fred',6000978
'Tom'.6000979
'Mary',6000980
'Larry',6000981
How can I reference Table2 so that Table2.SeqNo will 'line up' properly? Note that the ordering of the SeqNo values isn't mandatory as long as each SeqNo is assigned to one and only one row.
On edit: Table2 isn't required, it's just the way I started thinking about it. It would be nicer to just have two integer vars, @StartSeqNo = 6000978 and @EndSeqNo = 6000981 for he example above. Either way is fine.

I am finding it difficult to find an example that allows for insertion of additional rows into a table, without dropping the table I'm inserting into. Or inserting specific values. Like this example..

I have 6 table I am formatting the data to conform to the final table as I'm inserting it into, but none of these examples gives me the example needed. I am using SQL 2012.

An SSIS task imports data from a flat file and inserts the data into a staging table. The staging table holds the data in its raw form. A second process then selects the data from the staging table, looking up the foreign key id's for raw data values, and then inserts the data into the live table.
SQL - Only key columns shown for clarity
-- Staging Table
CREATE TABLE Staging
(Information VARCHAR(10),
MachineName VARCHAR(10),
Status VARCHAR(10))
[code]...
The insert into the live table should look up the id for machine 1, and the id of status success and insert the foreign key values into the live table for the row.There could be 1000's of rows for the output of machine 1 all with different status's - (all pre set in the Status table, i.e success, failure, rerun) and the same for lots of other machines held in the machine table.
What is the best to insert this data all in one go, rather than reading each row of the staging table one by one, looking up the foreign key values depending on the machine and status values, then inserting the data.
I was thinking along the lines of:
INSERT INTO dbo.LiveTable
(Information, MachineID, StatusId)
SELECT Staging.Information, dbo.Machine.MachineId, dbo.Status.StatusId
FROM dbo.Staging
JOIN Machine ON Machine.MachineName = Staging.MachineName
JOIN STATUS ON Status.Status = Staging.Status But I notice the problem with this is, it doubles up the inserts!

I have encountered some weird behaviour. Code that has been working for "eternities" suddenly started to fail. I couldn't recreate it on any other machines.
I have written a sample script to illustrate the issue:
CREATE TABLE #t_parcels (parcel_id INT, current_pos NUMERIC(28, 0), end_pos NUMERIC(28, 0))
CREATE TABLE #t_orders (outorder INT, parcel_id INT)
CREATE TABLE #t_missing_parcels (parcel_id INT, diff INT)
INSERT INTO #t_parcels (parcel_id, current_pos, end_pos)
SELECT1, 100000000000.0, 900000000000.0
[Code] ..
The last insert crashed with :"Arithmetic overflow error converting expression to data type int", even though there are no rows that satisfies the condition!
This is due to "diff" column having wrong datatype, BUT, the insert had no hits in the database. So how can inserting 0 rows crash with incorrect datatype?
I even copied the select so it was ran before the insert, in in that case, the SELECT completed successfully.
When i changed datatype in the table, the error went away, but I'm still curious what led to the error.

In a special request run, I need to update locker and lock tables in a sql server 2012 database, I have the following 2 table definitiions:
CREATE TABLE [dbo].[Locker](
[lockerID] [int] IDENTITY(1,1) NOT NULL,
[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[lockID] [int] NULL
CONSTRAINT [PK_Locker] PRIMARY KEY NONCLUSTERED
[code]....
The locker table is the main table and the lock table is the secondary table. I need to add 500 new locker numbers that the user has given to me to place in the locker table and is uniquely defined by LockerID. I also need to add 500 new rows to the corresponding lock table that is uniquely defined in the lock table and identified by the lockid.
Since lockid is a key value in the lock table and is uniquely defined in the locker table, I would like to know how to update the lock table with the 500 new rows. I would then like to take value of lockid (from lock table for the 500 new rows that were created) and uniquely place those 500 lockids uniquely into the 500 rows that were created for the lock table.
I have sql that looks like the following so far:
declare @SchoolID int = 999
insert into test.dbo.Locker ( [schoolID], [number])
select distinct LKR.schoolID, A.lockerNumber
FROM [InputTable] A
JOIN test.dbo.School SCH ON A.schoolnumber = SCH.type and A.schoolnumber = @SchoolNumber
JOIN test.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID
AND A.lockerNumber not in (select number from test.dbo.Locker where schoolID = @SchoolID)
order by LKR.schoolID, A.lockerNumber
I am not certain how to complete the rest of the task of placing lockerid uniquely into lock and locker tables?

I have a problem described as follows: I have a table with one instead of insert trigger:
create table TMessage (ID int identity(1,1), dscp varchar(50))
GO
Alter trigger tr_tmessage on tmessage
instead of insert
as
--Set NoCount On
insert into tmessage
[code]....
When I execute P1 it returns 0 for Id field of @T1.
How can I get the Identity in this case?
PS: I can not use Ident_Current or @@identity as the table insertion hit is very high and can be done concurrently.Also there are some more insertion into different tables in the trigger code, so can not use @@identity either.

Obviously its generate error msg for conversion, is there any workaround for this. I cannot add 0 or other value as this column is used to generate some output value.

I have wrote the stored procedure to do this. But the problem is If do the update. It is reflecting in the database by changing 0 to 1. But it shows error like cannot insert the duplicate
Here is the stored Procedure what i have wrote

Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.
The initial solution is:
1 Create a table (table_b) which structur is as the same as table_a
2 Use BCP to import updated records into table_b
3 Remove outdated data in table_a:
delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields
4 Append updated or new data into table_a:
insert into table_a select * from table_b
As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?
