Transact SQL :: Table Trigger To Delete All Rows Before Inserting Rows
Jul 24, 2015
I have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2
select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.
USE [BB]
GO
/****** Object: Trigger Script Date: 24/07/2015 3:41:38 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
I had created a trigger which sees that whether a database is updated if it is its copy the values of the updated row into another control table now I want to read the content of control_table into BIzTalk and after reading I want to delete it.Can any one suggest the suitable ay to do this?
Question pls. I have an MS SQL local package where it exports data from SQL table to Excel file. My question is, how can erase all the records in my excel file before i export the new data from SQL table?
What i want is to delete the rows in the destination file before inserting new records.
I write a insert trigger on my table LeaveRegister(1000 rows) and inserting rows in audit table, but when i inserting a row in LeaveRegister table. In audit table 1000 + 1 rows are inserting every time.
I have created a table Table with name as Varchar and id as int. Now i have started inserting the rows like, insert into Table values ('arun',20).Yes i have inserted a row in the table. Now i have got the values " arun's ", 50. insert into Table values('arun's',20) My sqlserver is giving me an error instead of inserting the row. How will you solve this problem?
I am trying to insert some new rows into an existing SQL table. The table name is Agt_table, and I want to add some data for some new agents into existing columns: Agent name, agent code, phone number, fax number
Example - I want to add the following record to my existing table Agt_table Agent name: ABC Company Agent code: 012345 Phone #: 555-555-5555 Fax#: 555-555-5555
Is it possible to insert multiple rows in a table using one INSERT statment. If yes, how can I do that ? I tried doing this using the substitution method.
Using Substitution Method - This is how,I proceeded.
I have a DataTable in memory and I want to write a C# code to dump the data into a SQL database. Is there a faster way of dumping millions of rows into a SQL table besides running INSERT INTO row by row?
Using the the NumId from TitleData, I would like to delete thecorresponding row in Bookdata using pure SQL. I want it to delete allrows in bookdata where the Titledata.NumID is a match to bookdata.idThe two tables are linked in that the NumId of table Titledata isidentical to the Id of table bookdata. I can, using ADO, loop thrudeleting one by one but I would like to do this in a pure SQLstatement. Is this possible? Any help is appreciated.I was thinking something like this way :"Delete from Bookdata where Titledata.NumID = Bookdata.id"But of course it will error.My current code is:(frmlogon.tablename is really Titledata)Dim rstry As New ADODB.RecordsetDim values As VariantSQLQuery = "Select Numid from " & frmLogon.TablenameSet rstry = frmLogon.cnConnection.Execute(SQLQuery)values = rstry.GetRowsSet rstry = Nothing'now loop thruDim xx As Integerxx = 0Do Until xx > UBound(values, 2)SQLQuery = "Delete from Bookdata where bookdata.Id = '" & values(0,xx) & "'"frmLogon.cnConnection.Execute (SQLQuery)xx = xx + 1Loop'create statements for 2 tables involved areconn.Execute "CREATE TABLE TitleData" & _"(Id INT IDENTITY (1, 1) NOT NULL PRIMARY KEY," & _"NumId INT DEFAULT 0 )"conn.Execute "CREATE TABLE BookData" & _"(Id INT IDENTITY (1, 1) NOT NULL," & _"Titles TEXT DEFAULT ''," & _"GeneralNote TEXT DEFAULT ''," & _"Author VARCHAR(100) DEFAULT ''," & _"Imprint VARCHAR(100) DEFAULT ''," & _"ISBN VARCHAR(100) DEFAULT ''," & _"Description VARCHAR(100) DEFAULT ''," & _"CallNumberPre VARCHAR(5) DEFAULT ''," & _"CallNumber VARCHAR(25) DEFAULT '',LOCNumber VARCHAR(30) DEFAULT '',"& _"Accession VARCHAR(25) DEFAULT ''," & _"Bibliography VARCHAR(100) DEFAULT ''," & _"Series VARCHAR(100) DEFAULT ''," & _"MyStatus VARCHAR(70) DEFAULT ''," & _"Barcode VARCHAR(50) DEFAULT ''," & _"LocalData VARCHAR(100) DEFAULT ''," & _"CheckoutPeriod VARCHAR(10) DEFAULT ''," & _"CatalogCard TEXT DEFAULT ''," & _"Summary TEXT DEFAULT ''," & _"MyCount VARCHAR(10) DEFAULT ''," & _"ItemDate DATETIME DEFAULT ''," & _"MyUser VARCHAR(50) DEFAULT ''," & _"MarcData TEXT DEFAULT ''," & _"SdlsRecord TEXT DEFAULT '', LOSC VARCHAR(5) DEFAULT '', LOSNDecimal(14,6) DEFAULT 0," & _"Edits Char(1) DEFAULT '', TitleDuplicate VARCHAR(50) DEFAULT '')"
Suppose you have a simple DML "execute as..." trigger that looks like this:
CREATE TRIGGER dbo.myTrigger ON dbo.myTable WITH Execute As Owner AFTER INSERT AS
[code]...
which runs as "owner" so that the user inserting into "myTable" won't have the privs to edit the audit table.How does one capture the identity of the user whose insert statement caused the trigger to fire? I've tried "current_user" and "system_user" without success when "execute as ..." is used: they each return a value not related to the identity of the user running the original insert.without an "execute as" clause, what prevents a user from adding to or editing the audit table directly?
I am using the below SQL to insert a table. The problem is after I run this, I run another script to populate the table (see below). The population script will work if I run it as INSERT INTO ... SELECT TOP 99.9999999 PERCENT ..., but if I put 100 PERCENT, or just use no percent limiter I get the following error: Msg 8624, Internal SQL Server error.
It is weird b/c once something is inserted in the table, i can run the populate script without any problems. Any idea as to why this is happening?
Thanks,
Dave

Hello all,my first post here...hope it goes well. I'm currently working onstored procedure where I translated some reporting language into T-SQLThe logic:I have a group of tables containing important values for calculation.I run various sum calculations on various fields in order to retrievecost calculations ...etc.1) There is a select statement which gathers all the "records" whichneed calculations.ex: select distinct Office from Offices where OfficeDesignation ='WE' or OfficeDesignation = 'BE...etc.As a result I get a list of lets say 5 offices which need to becalculated!2) A calculation select statement is then run on a loop for each ofthe returned 5 offices (@OfficeName cursor used here!) found above.Anexample can be like this(* note that @WriteOff is a variable storing the result):"select @WriteOff = sum(linecost * (-1))From Invtrans , InventoryWhere ( transtype in ('blah', 'blah' , 'blah' ) )and ( storeloc = @OfficeName )and ( Invtrans.linecost <= 0 )and ( Inventory.location = Invtrans.storeloc )and ( Inventory.itemnum = Invtrans.itemnum )"...etcThis sample statement returns a value and is passed to the variable@WriteOff (for each of the 5 offices mentioned in step 1). This is donearound 9 times for each loop! (9 calculations)3) At the end of each loop (or each office), we do an insert statementto a table in the database.
To anyone that is able to help....What I am trying to do is this. I have two tables (Orders, andOrderDetails), and my question is on the order details. I would liketo set up a stored procedure that essentially inserts in the orderstable the mail order, and then insert multiple orderdetails within thesame transaction. I also need to do this via SQL 2000. Right now ihave "x" amount of variables for all columns in my orders tables, andall Columns in my Order Details table. I.e. @OColumn1, @OColumn2,@OColumn3, @ODColumn1, @ODColumn2, etc... I would like to create astored procedure to insert into Orders, and have that call anotherstored procedure to insert all the Order details associated with thatorder. The only way I can think of doing it is for the program to passme a string of data per column for order details, and parse the stringvia T-SQL. I would like to get away from the String format, and gowith something else. If possible I would like the application tosubmit a single value per variable multiple times. If I do it this waythough it will be running the entire SP again, and again. Anysuggestions on the best way to solve this would be greatlyappreciated. If anyone can come up with a better way feel free. Myonly requirement is that it be done in SQL.Thank you
Now say I got two sellers (1 & 2), and only one article (1, offered by seller 1). The delete query should delete seller 2 because he is not offering articles anymore.
This probably is dead simple in SQL, something like DELETE FROM seller WHERE COUNT(article.SellerID=seller.ID)==0 but honestly, my SQL books leave me guessing here, and I found no online ref for cases like this.
I'm working on a database for a financial client and part of what i need to do is calculate a value from two separate rows in the same table and insert the result in the same table as a new row. I have a way of doing so but i consider it to be extremely inelegant and i'm hoping there's a better way of doing it. A description of the existing database schema (which i have control over) will help in explaining the problem:
id metric_id metric_type_id metric_name 1 80 2 Fiscal Enterprise Value Historic Year 1 2 81 2 Fiscal Enterprise Value Current Fiscal Year 3 82 2 Fiscal Enterprise value Forward Fiscal year 1 4 83 2 Fiscal Enterprise Value Forward Fiscal Year 2 5 101 3 Calendar Enterprise value Historic Year 1 6 102 3 Calendar Enterprise Value Current Fiscal Year 5 103 3 Calendar Enterprise value Forward Year 1 6 104 3 Calendar Enterprise Value Forward Year 2
Table Name: metric_type_details
id metric_type_id metric_type_name 1 1 Raw 2 2 Fiscal 3 3 Calendar 4 4 Calculated
The problem scenario is the following: Because a certain number of the securities have a fiscal year end that is different to the calendar end in addition to having fiscal data (such as fiscal enterprise value and fiscal earnings etc...) for each security i also need to store calendarised data. What this means is that if security with security_id = 3 has a fiscal year end of October then using rows with ids = 1, 2, 3 and 4 from the metrics_ladder table i need to calculate metrics with metric_id = 83, 84, 85 and 86 (as described in the metric_details table) and insert the following 4 new records into metrics_ladder:
Metric with metric_id = 101 (Calendar Enterprise value Historic Year 1) will be calculated by taking 10/12 of the value for metric_id 80 plus 2/12 of the value for metric_id 81.
Similarly, metric_id 102 will be equal to 10/12 of the value for metric_id 81 plus 2/12 of the value for metric_id 82,
metric_id 103 will be equal to 10/12 of the value for metric_id 82 plus 2/12 of the value for metric_id 83 and finally
metric_id 104 will be NULL (determined by business requirements as there is no data for forward year 3 to use).
As i could think of no better way of doing this (and hence the reason for this thread) I am currently achieving this by pivoting the relevant data from the metrics_ladder so that the required data for each security is in one row, storing the result in a new column then unpivoting again to store the result in the metrics_ladder table. So the above data in nmetrics_ladder becomes:
-- Dummy year variable to make it easier to use MONTH() function -- to convert 3 letter month to number. i.e. JAN -> 1, DEC -> 12 etc... DECLARE @DUMMY_YEAR VARCHAR(4) SET @DUMMY_YEAR = 1900;
with temp(security_id, metric_id, value) as ( select ml.security_id, ml.metric_id, ml.value from metrics_ladder ml where ml.metric_id in (80,81,82,83,84,85,86,87,88,etc...) -- only consider securities with fiscal year end not equal to december and ml.security_id in (select security_id from company_details where fiscal_year_end <> 'dec') ) insert into @calendar_averages select temppivot.security_id -- Net Income ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[80]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[81]) as [101] ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[81]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[82]) as [102] ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[82]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[83]) as [103] ,NULL as [104] -- Share Holders Equity ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[84]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[85]) as [105] ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[85]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[86]) as [106] ,(CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR))/12*[86]) +((12 - CONVERT(DECIMAL, MONTH(cd.fiscal_year_end + @DUMMY_YEAR)))/12*[87]) as [107] ,NULL as [108] -- Capex -- Sales -- Accounts payable etc... .. .. from temp pivot ( sum(value) for metric_id in ([80],[81],[82],[83],[84],[85],[86],[87],[88],etc...) ) as temppivot inner join company_details cd on temppivot.security_id = cd.security_id
********* END SQL *********
The result then needs to be unpivoted and stored in metrics_ladder.
And FINALLY, the question! Is there a more elegant way of achieving this??? I have complete control over the database schema so if creating mapping tables or anything along those lines would help it is possible. Also, is SQL not really suited for such operations and would it therefore be better done in C#/VB.NET.
Below is a simplified table & dataset to illustrate a problem I'm experiencing with a more complex one.
Code Block
create table #test( recno smallint PRIMARY KEY, value decimal (18,2))
insert into #test values (1, 3.57) insert into #test values (2, 5.32) insert into #test values (3,6.29) insert into #test values (4, 9.25) insert into #test values (5, 0.84)
Method 1: I tried inserting rows from #test into a temp table (#table) as follows
Code Block
declare @n as nvarchar(3) set @n = 1 while @n <= (select count(recno) from #test) begin exec (' insert into ##table select *, originalrecno = (select recno from #test where recno = '+@n+') from #test' ) set @n = @n + 1 end However, this yields an error message:
Code Block
Server: Msg 208, Level 16, State 1, Line 2 Invalid object name '##table'. Note - you can comment out the insert into ##table line above to view the results that I'm trying to put into ##table.
Method 2: next I tried explicitly creating ##table & rerunning the loop containing the insert
declare @n as nvarchar(3) set @n = 1 while @n <= (select count(recno) from #test) begin exec (' insert into ##table select *, originalrecno = (select recno from #test where recno = '+@n+') from #test' ) set @n = @n + 1 end This worked - it inserted the data from the select statements in the loop into ##table.
How to I return the row count as result of deleting some rows from a table? This this script correct below?? Here's my stored procedure script..
Code:

Hi there, I have a simple data flow from OLE DB to OLE DB that writes data from a view into a table. Is it possible to delete the table or the rows within the table before wirting the new data???
Hi All, I have a program which shows some manipulate data from 2 tables on a datagrid. I'm using another program to delete rows from both tables. (The second program activate from the PC using the RAPI dll). I have sometimes a problem deleting records. Actually the Datagrid is not suppose to be shown when the user use the second program, but since I'm not able to determine whether my first program is still running or not, is there an option to force the delete even if other program is using it? If not, is there a way to stop the first program?
I have two tables that are related by keys. For instance,Table employee {last_name char(40) not null,first_name char(40) not null,department_name char(40) not null,age int not null,...}Employee table has a primary key (combination of last_name and first_name).Table address {last_name char(40) not null,first_name char(40) not null,street char(200) not null,city char(100) not null,...}Address table has a primary key (combination of last_name, first_name andstreet in which (last_name, first_name) reference (last_name, first_name) inemployee table.Now I want to delete some rows in Address table based on department_name inEmployee table. What is sql for this delete?I appreciate your help. Please ignore table design and I just use it for myproblem illustration.Jim
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times WHERE EXISTS ( SELECT 1 FROM Users WHERE (A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND ((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
