I have a requirement that if in a table update happened based on 1st condition then it should insert in one way and if update happened on second condition the insert statement will differ. That is it should insert the deleted records i.e., previous records existed in a table.The syntax is like
CREATE TRIGGER [dbo].[tr_a] on [dbo].[A]
AFTER UPDATE
AS
BEGIN TRY
IF NOT EXISTS
[code]....
I m getting some syntactical errors.
Assuming I should be using values from temp inserted to insure correct record...
Need help coding IF...THEN INSERT statements in following After TRIGGER:
Create TRIGGER trg_insertItemRows
ON dbo.a_form
AFTER INSERT
AS
SET NOCOUNT ON
-- Checkbox Driven:
IF a_form.missingCheckbox = -1 THEN
Insert into b_items (form_ID, parent_ID, ItemTitle)
Values (Select Distinct i.form_ID,i.parent_ID from inserted i)', '+ 'User checked Missing Data')
-- Textbox Driven:
IF a_form.incorrectTxtbox <> 'na' THEN
Insert into b_items (form_ID, parent_ID, ItemTitle)
Values (Select Distinct i.form_ID,i.parent_ID from inserted i)', '+ Correction: Replace '+ incorrectTxtbox + ' with '+replaceWithTxtbox)
Sample code below:
-- Source table the Trigger acts on
Create Table a_form (
form_ID int Not Null,
parent_ID int,
missingCheckbox bit,
missingNote varchar(100),
incorrectTxtbox varchar(50),
replaceWithTxtbox varchar(50)
)
--Target table Trigger inserts into
Create Table b_items (
items_ID int Not Null,
form_ID int Not Null,
parent_ID int,
ItemTitle varchar(150)
)
I am trying to create a logon trigger. As I am testing this, I discovered that each time I do a connection, I get 19 rows, inserted into my audit table. I ran profiler, and I see it is going through the logon trigger multiple times, for a single connection. So, what am I doing wrong? The code is fairly simplistic, and the profiler doesn't give a clue, as to what is going on. When I look at the output, I see the spid for the first couple of connections are different, then a spid, that is different from those 2 is in the next 17 rows. But, when I do an sp_who2, that spid does not exist.
This issue was noticed on a 2012 version, that I was first testing on, then had the same issue on a 2008 R2. I am currently testing on a 2014 version, that is doing the same thing. Is the logon trigger itself, firing, and causing this?
I also tried using the After Logon option, and got the same issue.
Here is the code:
CREATE TRIGGER LogonAuditTrigger
ON ALL SERVER WITH EXECUTE AS 'sa'
FOR LOGON
AS
BEGIN
DECLARE @Body NVARCHAR(2000),

I've got a package that needs to do various single-row inserts/updates throughout the flow of the package. Each insert/update will use values from variables.
What is the best practice for doing this? I was going to use a DFT with my source being a derived column transformation, but it expects a true data source.
I've also thought about just using the obvious -- a SQL command task -- by my experience with doing commands using single values is that it's very quirky and hard to get the data types and mappings to cooperate.
I'm betting the SQL command task is my only option, but I wanted to check here first to see if others had other ideas.
Thanks in advance.

I am trying to create a trigger on a table. Let's call it table ABC. Table looks like this:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[ABC](
[id] [uniqueidentifier] NOT NULL,
[Code] ....
When someone updates a row on table ABC, I want to insert the original values along with the current date and time getdate() into table ABCD with the current date and time into the updateDate field as defined below:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[ABCD](
[id] [uniqueidentifier] NOT NULL,
[Code] .....
The trigger I've currently written looks like this:
/****** Object: Trigger [dbo].[ABC_trigger] Script Date: 4/10/2015 1:32:33 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER [dbo].[ABC_trigger] ON [dbo].[ABC]
[Code] ...
This trigger works, but it inserts all of the rows every time. My question is how can I get the trigger to just insert the last row updated?
I can't sort by uniqueidentifier in descending as those can be random.
Hi, I'm trying to create a form where new names can be added to a database.

MyConnection = New SqlConnection("server=databaseserver;database=db;uid=uid;pwd=pwd") MyCommand = New SqlDataAdapter("insert into certifications (name) values ('" & newName.Text & "'); select * from certifications", MyConnection)
DS = New DataSet MyCommand.Fill(DS, "Titles")

Iam in a situtation where i have a query Which Inserts into a table from Select statement. But there is another table which is dependent on the Primay key of the inserted table.
Since the insert is multiple iam not able to use the @@Identity.
Can some one suggest me How can i over come this situtation.
Also Triggers cant be used as the the records are of huge numbers.
Eg:-
INSERT INTO Users (FirstName, SecondName) SELECT FirstName, SecondName From Old_Users
INSERT INTO UserDependent(UserID,OtherFields)
VALUES(@@Identity,'SomeOtherValue')

hi I was just writing for some general advice. If I am to do many updates on a table is it okay to keep updating with many insert statements inside of a loop closing the connection each time? Here is some pseudo code to give you an idea:
cnn.open();
cmd = "insert into Cats values (red,4994,homer)";
for(int i=0; i<10000; i++)
{
cmd.executenonquery();
cnn.close();
}
I need to insert multiple rows for input rows that meet certain conditions.
My input data is as follows.
ZIPCode, Plus 4, Range, City, State
What I need to happen is that if there is a value in the range column that is > 0 then I need to insert a row for every range item.
For instance say I have the following data.
54952, 1001, 10, Menasha, WI
What I need imported is :
54952, 1001, Menasha, WI
54952, 1002, Menasha, WI
54952, 1003, Menasha, WI
54952, 1004, Menasha, WI
54952, 1005, Menasha, WI
54952, 1006, Menasha, WI
54952, 1007, Menasha, WI
54952, 1008, Mensaha, WI
54952, 1009, Mensaha, WI
54952, 1010, Mensaha, WI
54952, 1011, Mensaha, WI

Hello all,
I'm working on a project for fun with some friends and have run into an issue with stored procedures. I've dealt with SQL quite a bit at my current job, but always from the perspective of somebody querying the database. The database was always managed by someone else and I never had to worry about the underlying code. Now, with my own project at home, I'm trying to deal with a situation and would like to use one, but I'm not sure if it is the best option and if so, exactly how to go about it.
Imagine a site that tracks movies. I have 3 tables:
Movies ( MovieID, Title, DirectorID, ActorID )
Actors ( ActorID, Name )
Director (DirectorID, Name)
This is an overly simple example, but it gets to the heart of my problem.
Okay, now what I'm wanting to do is to be able to write a procedure that would let me create my entries from just one call -- for instance
create_movie( 'Super Movie', 'directorJoe', 'actorJohn' )
that would do the following things:
-Look and see if the given director and actor already exist (from previous films)
-If they do, grab their ID values and use those in the new movie entry
-If they do not, create new entries and get THOSE ID values to use in the new movie entry
Can this be done in a stored procedure (I'm pretty sure it can be) and what sort of commands should I look into -- I'm not looking for a complete solution, cause I want to learn, but I am having trouble finding examples that fit my scenario.
Thanks.
Hello,
I have a stored procedure that updates my table with values entered in a datatable in my windows app.
An error occurs 1/2 way through the update process. I assumed that by implementing the rollback transaction command that the inserted lines would not be saved to my db. This is not the case.
I will elaborate a little more on what I need. From my windows app I have a datatable with 100 new rows that need to be written to my db. This I can do. However, a problem crops up should there be an error during the transfer. Let's say I have 100 rows in my datatable in my windows app, and row 57 causes an error, what is happening is that rows 1-56 are committed and 57-100 are not. What I need is for 1-100 to NOT be committed to my DB should there be a snag along the way. I need a code sample as I'm having way too much difficulty with this as is.
The basic code that copies to my db(sans rollback):
BEGIN
SET NOCOUNT ON
INSERT INTO userprofile (uid, uname, ustatus)
VALUES @userid, @username, @userstatus;
END
Thank You.
I am trying to insert a message into my database for every "league" I have in the database. I would like to do this in one sproc but am not sure how this would be done. Here is the loop if it has to be done outside of sql

leagues[] = getAllLeaguesInSite()

Hi all,
I am writing a portion of an app that is of intensely high online eCommerce usage. I have a question about identity columns and locking or not.
What I am doing is, I have two tables (normalized), one is OrderDemographics(firstname,lastname,ccum,etc) the other is OrderItems. I have the primary key of OrderDemographics as a column called 'ID' (an Identity Integer that is incrementing). In the OrderItems table, the 'OrderID' column is a foreign key to the OrderDemographics Primary Key column 'ID'.
What I have previously done is to insert the demographics into OrderDemographics, then do a 'select top 1 ID from OrderDemographics order by ID DESC' to get that last ID, since you can't tell what it is until you add another row....
The problem is, there's up to 20,000 users/sessions at once and there is a possiblity that in the fraction of a second it takes to select back that ID integer and use it for the initial OrderItems row, some other user might have clicked 'order' a fraction of a second after the first user and created another row in OrderDemographics, thus incrementing the ID column and throwing all the items that Customer #1 orders into Customer #2's order....
How do I lock a SQL table or lock the Application in .NET to handle this problem and keep it from occurring?
Thanks, appreciate it.

Hi,
I have multiple columns in a Single Table and i want to search values in different columns. My table structure is
col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))
I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1
ON
TBL.col1=TBL1.[key]
INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result = 1 row
But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4
FROM
TBL
INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON
TBL.col1=TBL1.[key]
Result=0 Row
Any idea how i can write second query to get result?
Here is some data that will explain what I want to do:

How to insert single row/multiple rows into multiple tables by using single insert statement.
View 1 Replies View RelatedI want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks

So, I know, after searching these forums, that it is possible to disable a trigger before updating a table and then enabling it again afterwords, for instance, from a stored procedure.
I might be dealing with hypotheticals here, but when I do a ...
ALTER TABLE table
{ ENABLE | DISABLE } TRIGGER
{ ALL | trigger_name [ ,...n ] }
... from a stored procedure, will it not be database wide?
Should I worry about another change to the table happening in the timespan in which the trigger is disabled (which it would be for during a single update), which the trigger should have caught?

I have this table:
CREATE TABLE Workspaces (
AreaNr CHAR(2)
CONSTRAINT ck_a_areanr REFERENCES Areas(AreaNr)
ON DELETE CASCADE
[Code] ....
Now I want to create a trigger that prevents a delete on a single row (randomly chosen) from the table Workspaces. At the moment I have the following trigger, but this trigger still allows removal of single rows.
Current trigger:
CREATE TRIGGER deleteWorkspace ON Workspaces
FOR DELETE AS
BEGIN
DECLARE @Count int
SET @Count = @@ROWCOUNT;

Desired result: I want to be able to prevent a delete on a single row on the table above.

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob

Hi everyone,
Im having a hard time deciding what approach should I take. The scenario is this: I have developed various systems (inventory, HR, accounting, etc.). All this systems are (and should be) tightly integrated with one another. At present, for all these systems, i've used a single DB prefixing the tables with the systems name (eg. Inventory.Items).
My question is: did I did the right (and practical) thing? Or should I create a DB for each system to organize them? The problem with multiple DBs is some system uses the other system's table(s). Example, if i created a separate DB for accounting, and a separated DB for inventory, and another for HR, how am I going to relate inventory and HR's accounts to the accounting DB's table? I want a single instance for each table; I don't want to create another account table for inventory or HR so I can enforce integrity. And if different DBs, is there a performance impact on this?
Or is there another way? My concern is performance and manageability. Please help. Thanks!
