SQL Server 2012 :: How To Cancel A Query If A Condition Is Not Met
Apr 23, 2015
Is it possible to stop a query from running if a condition is not met?
I have a stored procedure that returns some email addresses. A condition is that a load of new data should have happened in the current month.
If a load of new data hasn't happened I want the stored procedure to stop and return an error message instead of returning the email addresses.
I have a variable that finds the maximum data load date and I thought I could use an IF... ELSE... to check if new data had been loaded. Like this:
DECLARE @MaxLoadDate as date = (select max(load_date)
from #table)
IF @MaxLoadDate<Dateadd(month, Datediff(month, 0, Getdate()), 0) --First Day of Current Month
<Something here to kill the query>
ELSE
SELECT email_address
FROM... etc
I've tried a couple of things like PRINT 'Error', and SET NO EXEC ON, but the query seems to happily carry on past the IF condition and return the email addresses. I know that data hasn't been loaded this month, so it should fail.

Now, on the above query I want to insert three extra columns with the name (status, location and contact) where the results in the extra three columns would be based on the conditions I want to define in the query based on the above results…
Something for example (I am not trying to write a condition: my question is how to write it),
if column_code1 = RO1 and column_description2 = PDF/ECOPY on status column it should return a value ‘ONLINE’ & on location column it should return ‘WEB’ and on contact column it should write ‘BOB’.
Also, if column_code1 = RO5 and column_description1 = JOURNAL on status column it should return a value ‘ON PRESS FOR PRINT’ & on location column it should return ‘S.R STREET, LONDON’ and on contact column it should write ‘SMITH’ like below result…so the final output should be the top four columns and the extra three columns…
See the attachment for better formatting...
--------------------------------------------------------------------------------------------- status location contact --------------------------------------------------------------------------------------------- ONLINE WEB BOB ON PRESS FOR PRINT S.R STREET, LONDON SMITH
I want to identify rows that go negative but only for 2 cents or more as well as identify rows that 2 or more.
I have this expression that does not work how I want it to work:
CASE WHEN (SUM(FavUnfavCostChange) < (2/100) THEN 'Less' WHEN SUM(FavUnfavCostChange) > (2/100) THEN 'More' ELSE NULL END AS 'Flag'
But I get:
0.00000815000000000000More -- this is not more than 2 cents, is just a positive number -0.00094700000000000000Less -- this is not less than 2 cents, is just negative number -0.00222000000000000000Less -- this is not less than 2 cents, is just negative number -0.00012250000000000000Less -- this is not less than 2 cents, is just negative number 0.00000000000000000000NULL -- this is zero so null is fine 0.01188576000000000000More -- this is not more than 2 cents, is just a positive number
I want to write a query that will cycle through the results and if it comes across another record that has a matching Table.ID I want to exclude that row from the result set.
I am not all too familiar with how to use either a Case or If..Else Statement within a Sql statement that would accomplish this.
I am trying to add a where condition on an ID column(type - INT) with values coming from a variable (type - STRING). i am using cast to cast the ID as Varchar and then apply the condition, but i am not getting any results back. following is an example of what i am trying to do.using temp table in the example , so you can copy the t-sql and run as is.
I want to join 2 tables, table a and table b where b is a lookup table by left outer join. my question is how can i generate a flag that show whether match or not match the join condition ?
**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a id country area 1 China Asia 2 Thailand Asia 3 Jamaica SouthAmerica 4 Japan Asia
example table b id country area 1 China Asia 2 Thailand SouthEastAsia 3 Jamaica SouthAmerica 5 USA America
Expected output id country area Match 1 China Asia Y 2 Thailand SouthEastAsia Y 3 Jamaica SouthAmerica Y 4 Japan Asia N
I have to write a select query which need some logic to be implemented. Query is like select name,number,active, if active ="true" then select @days=days from tbl_shdsheet else @days='' end from tbl_emp In the above query there will be days row for that employee if active is true else there won't be any data for that emp in the tbl_shdsheet So how can i write queery for this.
I wish to make a query with if condition Implemented in a database sql server 2008 R2.
I would like to set up a system FEFO (first expired first out) based on batch number based on the dates of Lapsed but since I struggle to put my request in place. The principle of my request is:
if amount of movement (QTEMVT)> = amount entered by the user via a user interface then withdraws the amount entered by the user in the batch (NUMLOT) the amount of movement of the item that lapses the first (execution of my request). else if amount of movement (QTEMVT) <amount entered by the user then the difference between the amount entered by the user and the amount of movement (QTEMVT) (execution of my request) and the following conditions: the amount of movement (QTEMVT) = the amount of movement (QTEMVT) of this item stored in my database and the amount of movement (QTEMVT) <> 0 by taking the difference of the item requested directly from the batch (NUMLOT) of the item directly after lapses.
Basically I want to set up an item management query based on batch number and expiration dates.
ps: QTEMVT = quantity of the item stored in my database NUMLOT = batch number items DATFABRIC = manufacturing date items DATPEREMP = expiry date items
Here is my request:
SELECT f.NUMLOT,f.DATFABRIC,f.DATPEREMP,f.QTEMVT FROM FAIRE f INNER JOIN mouvement m ON f.CODMVT = m.CODMVT INNER JOIN TYPE_MOUVEMENT tm ON tm.CODTYPMVT = m.CODTYPMVT INNER JOIN SOUS_SITE ss ON ss.CODSOUSIT = m.CODSOUSIT INNER JOIN SITE s ON s.CODSITE = ss.CODSITE
I only want to UniqIds that only have the CODE of ABC... and if it contains ANYTHING other than ABC then It doesnt return that UniqID... Now keep in mind there's multiple different codes.. I'm just looking for a bit of code that drops any ID's that don't have my criteria.
I have a table where I need to concatenate and sum based on conditions given below .
CREATE TABLE #DimOrder ( [ID] [INT] IDENTITY(1,1) NOT NULL, [OrderID] [INT] NOT NULL, [SalesRegion] [VARCHAR](5) NULL, [OrderType] [INT] NOT NULL,
[Code] ....
Example SELECT 1296 AS OrderID, 2547 AS ProjectID,364 AS ProductID,6 AS FormatID,66 AS MEdiaTypeID,'Fast Track,Fast Track' AS ProductComment,'sq mi' AS UOM,'Y' AS FormatName,'LTO4_800' AS MEdia ,41.67000 AS aPPLIEDRATE
IF OrderID,PrjectID,ProductID,FormatID,MediaTypeID AND AppliedRate AND ProductComment IS different , THEN I want TO concetenate ProductComment AND sum AppliedRate
Example SELECT 1207 AS OrderID, 2351 AS ProjectID,364 AS ProductID,6 AS FormatID,32 AS MEdiaTypeID,'no charge,final volume' AS ProductComment,'sq mi' AS UOM,'Y' AS FormatName,'3590E' AS MEdia ,55.56000 AS AppliedRate
I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.
I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.
I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).
So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.
Create table #table (id int identity , from_country varchar(20) , to_country varchar(20),noofdays int, datetravel datetime ) insert into #table(from_country,to_country,noofdays,datetravel) values ('Malaysia','India',2,getdate()-99), ('India','Singapore',4,getdate()-88), ('Singapore','China',5,getdate()-77), ('China','Japan',6,getdate()-66), ('Japan','USA',7,getdate()-55) select * from #table
I want to insert data to another table based on "noofdays" columns. If "noofdays" is 4 then 4 rows should inserted to new table with 1 day increment in "datetravel" column.
Ex : #table 1MalaysiaIndia22015-02-09 02:04:09.247 2IndiaSingapore42015-02-20 02:04:09.247
[code]...
In #table , 1st row noofdays is 2 , so in new table #table_new first 2 rows should inserted with 1 day increment in "datetravel" column.
Hello,I have a gridview bound to a sqldatasource control. I have an emptydatatemplate setup. In the selecting event, I make sure that an actual select has been performed (and not on null data); however, I have cancelselectonnullparameters set to true to stop it, because initially it will be null.However, the selecting event runs, even when I cancel it, the emptydatatemplate shows up. How do I prevent that from occuring?
I have canceled a update statement that was running against a very large table. Now it is attempting to rollback all of the changes. Is there any way to cancel this? The table contains test data I would just like to drop it and recreate it, however I am getting an error when I attempt to drop the table because it is attempting a rollback.
I've execute a wrong sql request from an ETL. This request is inserting lots of rows in a table. I want to cancel that process, is it possible to do this? If yes, how can I cancel that request?
However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.
how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120)) insert into #temptable SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10 --column name declare @cname varchar(30)
I am creating a stored procedure which takes a few paramaters. One of which is a string of comma separated codes. At the end of my select query the codes will be used in the where clause.
What I'm doing is parsing the comma separated string and populating a temp table called #codes. So my query will look something like this:
select * from tableA where tableA.col1 = 'something' and tableA.code in (select * from #codes) and....
However, the code paramater can be null and if this is the case I want the query to be called for all codes - i.e. I effectively want to remove the and tableA.code in (select * from #codes) part of the where clause.
Is there any clever way of doin this other than having a if... else... and writing 2 queries - one with the and and one without it?
Hello all, I've got some problem with the following query: select subscriber_id, sum(convert(int,n_inboundcalls)) as totalinbound from calldiversityratedaily where totalInbound < 10 group by subscriber_id
The error message provided is: Server: Msg 207, Level 16, State 3, Line 1 Invalid column name 'totalInbound'.
I'm using MSSQL server 2000, version 8.00.194 and it appears that I can't use the name I give to the sum in the where clause. Could anyone help me please?
I have a SQL Server 2005 Compact Edition database that synchronizes with a SQL Server 2005 Standard database via merge replication.
The problem I have is when I cancel a synchronization, the database is left in such a state that I cannot add any new records. I dug around a bit and have found that in the INFORMATION_SCHEMA.COLUMNS view, AUTOINC_MAX has been incorrectly set to the same value as AUTOINC_MIN for the primary keys, which explains the 'out of range' error I get in my program when running off such a database.
In contrast, a non-corrupted database has AUTOINC_MAX set to AUTOINC_MIN + 999, presumably because of my subscriber identity range of 1000.
If this is the only thing that has gone wrong, all I need to do is programmatically set the AUTOINC_MAX values to AUTOINC_MIN + 999, however I can't find out where to do this (and INFORMATION_SCHEMA.COLUMNS is a view so it can't be updated obviously.)
I have also heard that 'compacting' the database may help, but I don't know how to do this either!
Now I should issue a sql which should extract the CustomerID where UserID in (‘U2’,’U4’) or (U2 or U4) in OtherUsers. i.e I should get the CustomerIDs C2,C4,C6,C8
I have trouble in coming out with the sql. Does anyone have idea how to achieve this?
From this I have to form the where clause like "Name like'3X5900' ".This will be dynamic , as the search may vary on the next call for search.
How I have to implement this dynamic query in the below mentioned code.I have add the dynamic query where i have mentioned as '---- Where clause has to be added '. Sometime the table input will be having all the value for search. How I can implement this in my query with good performance.
DECLARE @Where varchar(4000); Select @where = 'v.Name LIKE ''3X5900''' SELECT * from (SELECT Row_number()Over(Order By V.ProjectId) Rownum, v.Firstname,
