Looking for a smarter way to code the following. I have a stored
procedure I will be passing several variables to. Some times, some of
the fields used in a WHERE clause will not be passed, and I would like
to avoid having to code a bunch of if statements to set the executing
code. For example, below I would only like to execute the LIKE
conditions only when the variable in question is not NULL. I did a
test and if the variable is set to null, obviously the select does not
return what I'm expecting.
if @switch = "B"
SELECT * from ikb where
ikbtitle like @ins1 and
ikbtitle like @ins2 and
ikbtitle not like @ins3 and
ikbbody like @ins1 and
ikbbody like @ins2 and
ikbbody not like @ins3
end
I have a data model with 7 tables and I'm trying to write a stored procedure for each table that allows four actions. Each stored procedure should have 4 parameters to allow a user to insert, select, update and delete a record from the table.
I want to have a stored procedure that can accept those 4 parameters so I only need to have one stored procedure per table instead of having 28 stored procedures for those 4 actions for 7 tables. I haven't found a good example online yet of conditional logic used in a stored procedure.
Is there a way to add a conditional logic IF statement to a stored procedure so if the parameter was INSERT, go run this statement, if it was UPDATE, go run this statement, etc?
I am new to trying to do IF/THEN logic in a stored procedure. I want to return one query if @property=1 and another if @property=0. Can anyone give me a hint in how to do this correctly. Here's the basic idea of what I am doing:
Create Procedure "get_orders_by_date_and_card" @property int =0 as
if @property=0 begin SELECT stores FROM shops_master_Table end else begin SELECT restaurants FROM restaurant_master_table end return
is there a way of checking if the component is already in the data base if it is then just get the CompID and attach that CompId in the AppsComponents link table and put that in the AppComponents table. the snapdate field is to be the current datetime when the data is collected. Is there a current date function in SQL server? Is it possible to do this in a stored procedure?
I am working with stored procedures to provide conditional business logic for a customer based on triggers. Is it possible for a stored procedure to execute an external program ie opening or distributing a crystal report?
I have a stored procedure using UNION joins on three SQL queries. Sadly, I'm only now learning how to use Stored Procedures, so if this is a really dumb question, please forgive me. I'm not used to big UNION statements like this either... usually I'm just programming websites to serve information out pretty simply :) I need to return one result set, sorted by date... one complete result per day. eg: 5/15/2007 | XX | XX | XX | XX | XX | XX |5/16/2007 | XX | XX | XX | XX | XX | XX |5/17/2007 | XX | XX | XX | XX | XX | XX | Currently, when I run the query, I'm getting three separate date values for each date... eg:5/15/2007 | XX | XX | 00 | 00 | 00 | 00 |5/15/2007 | 00 | 00 | XX | XX | 00 | 00 |5/15/2007 | 00 | 00 | 00 | 00 | XX | XX |5/16/2007 | XX | XX | 00 | 00 | 00 | 00 |5/16/2007 | 00 | 00 | XX | XX | 00 | 00 |5/16/2007 | 00 | 00 | 00 | 00 | XX | XX |etc How do I fix this? I've looked through my query ad naseum and don't see anything that sets me off as "wrong". Here is the stored procedure if you can help. I'd really really love the help!

Is there any way to use conditional SQL in the SELECT clause of a stored procedure, i.e., use an IF-THEN to SELECT either COUNT(*) or a column-list based on the value of a parameter passed to the stored procedure? (I'd like to avoid having two sets of queries with the same WHERE clause).
I need to create a stored procedure for a report Web page which allows the user to specify different criteria. Is there a way to conditionally add different WHERE clauses as needed to a SQL SELECT statement?
I need to create a stored proc which has a conditional WHERE clause depending on the value of a passed parameter. I'm having trouble handling the condition. I'm missing something here.
I need to create a conditional if or case statement in SQL Server 2000 for a stored procedure. Basically if the value passed in is 1,2 or 3 then it will order by either NEWID(), a text field or a datetime feild.
Not done much dynamic sql so any help would be appreciated.
I want to return a subset of data from my 'items' table using a stored procedure based on a number of parameters as follows :
customer code varchar(8) userid varchar(10) status tinyint
where the customer code can be any valid customer code OR blank, the userid can be any valid userid or blank and the status can be 1 (item is open), 2 (item is closed) or 3 (item is open or closed, i.e. no filter on status)
Is there a better way to achieve this than the following disaster:
IF LEN(RTRIM(LTRIM(@custcode))) = 0 BEGIN IF LEN(RTRIM(LTRIM(@userid))) = 0 BEGIN IF @status = 1 BEGIN -- SELECT Query here !! END ELSE BEGIN IF @status = 2 BEGIN -- SELECT Query here !! END ELSE BEGIN -- SELECT Query here !! END END ELSE BEGIN IF @status = 1 BEGIN -- SELECT Query here !! END ELSE IF @status = 2 BEGIN -- SELECT Query here !! END ELSE BEGIN -- SELECT Query here !! END
END
END ELSE BEGIN IF LEN(RTRIM(LTRIM(@userid))) = 0 BEGIN IF @status = 1 BEGIN -- SELECT Query here !! END ELSE IF @status = 2 BEGIN -- SELECT Query here !! END ELSE BEGIN -- SELECT Query here !! END
END ELSE BEGIN IF @status = 1 BEGIN -- SELECT Query here !! END ELSE IF @status = 2 BEGIN -- SELECT Query here !! END ELSE BEGIN -- SELECT Query here !! END
I have a table that has incremental values, so the maximum value is the current total, however on occassion the value is reset and the increment begins anew. What I need to do is get the total the maximum value each time it is reset.
ie.
Value Date ----- ----- 12 1-1 14 1-2 100 1-8 35 1-10 50 1-12 5 1-15
Hi all, I created a stored procedure which perfoms a simple select like this: CREATE PROCEDURE Reports_Category ( @loc varchar(255), @pnum varchar(255) ) AS declare @vSQL nvarchar(1000) set @vSQL = 'SELECT ' + @loc + ', ' + @pnum + ' FROM Category ' exec sp_executesql @vSQL RETURNGO It takes field names as parameters. What happens is that when I supply value to only one parameter, the procedure gives error as it is expecting both values. Is there a way to make these parameters work like an 'OR' so that the procedure returns a dataset even if there is only one value supllied. Please help, Thanks, bullpit
I'm converting some direct SQL queries into stored procedures. The original queries have conditional parts appended depending on certain parameters like this:
Sql = "First part" If certain condition then Sql &= "Second part" Endif
How could I do this in a stored procedure? So far I have made them like this:
IF @condition > 0 Fist part Second part ELSE First part
You can see that I have to maintain 'First part' in two locations. What is a better way of dealing with this?
Created a stored procedure which returns Selected table from database. I pass variables, according to conditions
For some reason it is not returning any result for any condition
Stored Procedure
ALTER PROCEDURE dbo.StoredProcedure ( @condition varchar(20), @ID bigint, @date1 as datetime, @date2 as datetime )
AS /* SET NOCOUNT ON */ IF @condition LIKE 'all' SELECT CllientEventDetails.* FROM CllientEventDetails WHERE (ClientID = @ID)
IF @condition LIKE 'current_events' SELECT ClientEventDetails.* FROM ClientEventDetails WHERE (ClientID = @ID) AND (EventFrom <= ISNULL(@date1, EventFrom)) AND (EventTill >= ISNULL(@date1, EventTill))
IF @condition LIKE 'past_events' SELECT ClientEventDetails.* FROM ClientEventDetails WHERE (ClientID = @ID) AND (EventTill <= ISNULL(@date1, EventTill))
IF @condition LIKE 'upcoming_events' SELECT ClientEventDetails.* FROM ClientEventDetails WHERE (ClientID = @ID) AND (EventFrom >= ISNULL(@date1, EventFrom))
IF @condition LIKE '' SELECT CllientEventDetails.* FROM CllientEventDetails
RETURN
Also I would like to find out if I can put only "where" clause in if condition as my select statements are constants
I'm trying to convert the query immediately below into a function with the conditional logic to return a VARCHAR value with the gender: male, female or unknown.
SELECT empid, firstname, lastname, titleofcourtesy, CASE WHEN titleofcourtesy IN('Ms.', 'Mrs.') THEN 'Female' WHEN titleofcourtesy = 'Mr.' THEN 'Male' ELSE 'Unknown' END AS gender FROM HR.Employees; GO
Below is the conditional logic function I'm trying to create to replicate the logic above.
CREATE FUNCTION dbo.Gender ( @male AS VARCHAR(10), @female AS VARCHAR(10), @unknown AS VARCHAR(10) ) RETURNS VARCHAR(10)
I am writing a stored procedure that takes in a customer number, a current (most recent) sales order quote, a prior (to most current) sales order quote, a current item 1, and a prior item 1, all of these parameters are required.Then I have current item 2, prior item 2, current item 3, prior item 3, which are optional.
I added an IF to check for the value of current item 2, prior item 2, current item 3, prior item 3, if there are values, then variable tables are created and filled with data, then are retrieved. As it is, my stored procedure returns 3 sets of data when current item 1, prior item 1, current item 2, prior item 2, current item 3, prior item 3 are passed to it, and only one if 2, and 3 are omitted.I would like to learn how can I return this as a one data set, either using a full outer join, or a union all?I am including a copy of my stored procedure as it is.
Hey guys,I have to import a csv file to my database and then add some values to other fields based on these values. At present I use a store procedure that does a bulk insert and then I use an update and fetch inside the sql to perform these updates. I am not sure if this is the best way. Is this bad, since some amount of busniess logic is in the store procedure?If it is, how can I do this better?Thanks for the answer.
Hello,I stuck in a delimma.Where to put the business logic that involves only one updatebut N number of selects from N tables........with N where conditions
Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie exec dbo.DeriveStatusID 'Created' returns an int value as 1 (performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie: exec dbo.AddProduct_Insert 'widget1' which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) I want to simply the insert to perform (in one sproc): SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example). My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?
I have a table (currently with no constraints or relationships) with two columns:

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?

Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.
I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.
How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?
Has anyone encountered cases in which a proc executed by DTS has the following behavior: 1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio 2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+) The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query) The Update ad-hoc query will finish in 2 minutes
