Pass Output Of A Function To Another Function As Input
Jan 7, 2014
I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.
hi all i am using VS 2005 with SQL Server 2005 and i faced a problem that need to be solved urgently... i want to make a function that take a table as input parameter which is the output of a stored procedure (Record set)... first i found that to make w table be as input parameter you must create type of that table first but i found that sql server 2005 doesn't have the 'table' as a type... please any help will be appreciated thanks in advance
i want to make a function that will take a table as input parameter. this table will be the output of a stored procedure. while i were writing the function i have an error and when i read about it i found that i can not send a table as input parameter to a function till i create a new TYPE of this table with its columns and data types as UDT but i found that sql server 2005 does not support the type 'table'... my question now is it possible technically to make this function? is it possible to write something like that :
SELECT dbo.MyFunction(exec dbo.MystoredProc)
and in my function i am using CLR-Integration as this : create function MyFunction ( @TempTable table ( ContractID int, ContractNumber nvarchar(20), Name_En nvarchar(80), Name_Ar nvarchar(80), ContractAmount money, CurrencyID nchar(3), DateStart smalldatetime, DateEnd smalldatetime, Currency_En nvarchar(30), Currency_Ar nvarchar(30) ) ) returns table( ContractNumber nvarchar(20), Name_En nvarchar(80), Name_Ar nvarchar(80), ContractAmount decimal, Currency_En nvarchar(30), Currency_Ar nvarchar(30), [Year] int, [Month] int, DomesticAmount decimal ) as external name [AssemblyName].[PathOfTheFunctionInTheAssembly].[FunctionNameInAssembly]
please help me in this code as i need it urgently... thanks in advance, best regards, Moustafa
I am trying to use a Execute SQL task in which I call a query and get back a scalar value. I THINK I have it set up correctly, yet I am getting a very unhelpful error message of:
Error: 0xC002F210 at Determine Previous Trade Date, Execute SQL Task: Executing the query "SELECT[Supporting].[dbo].[fGetOffsetTradeDate](?, -1) AS [PreviousTradeDate]" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The Parameter Mapping has a single INPUT entry of data type DATE mapped to parameter 0.
The Result Set property (in General) is set to Single Row and there is a single entry in the Result Set config which maps [PreviousTradeDate] to a variable.
Odd thing is, if I replace the ? in the query with a date (say '03/24/2006') everything works fine. This would indicate that my query syntax is fine.
i have on table temp and it has column name fhID, now that column name and table name comes as parameter in stored procedure from c#. now stored procedure has code somthing like below @column nvarchar(50) @tbname nvarchar(50) -- both are parameter comes from c# decalre @maxid select @maxid=max(@column) from @tbname rather than prints the maximum values of "fhid" it prints column name itself. now i how can i achive actual working of max function using parameter. is there any other way to pass parameter in aggregate function or it is not allowed to pass.??? plz help me, thanks vishal parekh 'fhid' now how can
Hi Friends,Is it possible to pass a table as a parameter to a funtion.whos function declaration would look some thing like this....ALTER FUNCTION TempFunction (@TempTable TABLE, @nPId INT)my problem is: i have to access a temporary table created in an SP ina functionALTER PROCEDURE MySPBEGIN....DECLARE @TmpTable TABLE(...)....TempFunction(@TmpTable)....ENDThanksArunDhaJ
In the snippet below, ExecuteSqlString is a stored procedure that accepts one parameter. SelectChangeDropdownRowsource is a function in my code behind page that generates the string I want to pass. I can't seem to find the correct syntax to get it to work. The way it is show below, the error comes back about incorrect syntax near ')' . Is this doable? <asp:SqlDataSource ID="ChangeInfo" runat="server" ConnectionString="<%$ ConnectionStrings:xxx %>" DataSourceMode="DataReader" ProviderName="<%$ ConnectionStrings:xxx %>" SelectCommandType=StoredProcedure SelectCommand="ExecuteSqlString"> <selectparameters> <asp:parameter name="sqlString" Type=String DefaultValue=SelectChangeDropdownRowsource()/> </selectparameters> </asp:SqlDataSource>
I created a custom function that accepts an array of strings as a input. I need to pass several fields from the dataset to this function as an array. How can I do this?
I want to change decimal precision dynamically without rounding value
For example
10.56788 value for 2 decimal precision is 10.56. 10.56788 value for 3 decimal precision is 10.567. ---CASE 1 without dynamic parameter--------- DECLARE @DECIMALVALUE AS tinyint SELECT CONVERT(DECIMAL(10,2),500000.565356) As Amount
[Code] ....
I am getting error as follows......
Msg 102, Level 15, State 1, Line 3 Incorrect syntax near '@DECIMALVALUE'
This decimal precision format value will vary company to company ...
Hi I need a function which gets 3 parameters and input and returns 4 integers as output. I don't know how to return 4 integers as output any idea is appreciated.
I would like to wrap the following code in a function and reuse it. I use this code in many triggers.
DECLARE @Action as char(1); SET @Action = (CASE WHEN EXISTS(SELECT * FROM INSERTED) AND EXISTS(SELECT * FROM DELETED) THEN 'U' -- Set Action to Updated. WHEN EXISTS(SELECT * FROM INSERTED) THEN 'I' -- Set Action to Insert. WHEN EXISTS(SELECT * FROM DELETED) THEN 'D' -- Set Action to Deleted. ELSE NULL -- Skip. It may have been a "failed delete". END)
Is it possible to write a function and pass the INSERTED and DELETED logical tables to it?
I used the MERGE function for the first time. Now I have to create a pipe-delimited delta file for a 3rd party client of any deltas that may exist in our database.
What is the best way to do this? I have OUTPUT to a result set of the deltas...but I have to send over the entire table to the 3rd party via a pipe-delimited file.
I have this function in access I need to be able to use in ms sql. Having problems trying to get it to work. The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String Dim strReturn As String If IsNull(strField) = True Then strReturn = "" Else strReturn = strField Do While Left(strReturn, 1) = "0" strReturn = Mid(strReturn, 2) Loop End If TrimZero = strReturnEnd Function
I started with an inline table returning function with a hard coded input table name. This works fine, but my boss wants me to generalize the function, to give it in input table parameter. That's where I'm running into problems.
In one forum, someone suggested that an input parameter for a table is possible in 2012, and the example I saw used "sysname" as the parameter type. It didn't like that. I tried "table" for the parameter type. It didn't like that.
The other suggestion was to use dynamic sql, which I assume means I can no longer use an inline function.
This means switching to the multi-line function, which I will if I have to, but those are more tedious.
Any syntax for using the inline function to accomplish this, or am I stuck with multi-line?
A simple example of what I'm trying to do is below:
Create FUNCTION [CSH388102].[fnTest] ( -- Add the parameters for the function here @Source_Tbl sysname ) RETURNS TABLE AS RETURN ( select @Source_Tbl.yr from @Source_Tbl )
Error I get is:
Msg 1087, Level 16, State 1, Procedure fnTest, Line 12 Must declare the table variable "@Source_Tbl".
If I use "table" as the parameter type, it gives me:
Msg 156, Level 15, State 1, Procedure fnTest, Line 4 Incorrect syntax near the keyword 'table'. Msg 137, Level 15, State 2, Procedure fnTest, Line 12 Must declare the scalar variable "@Source_Tbl".
I need to create an output from a T-SQL query that picks a numeric variable and uses the print function to output with leading zeroes if it is less than three characters long when converted to string. For example if the variable is 12 the output should be 012 and if the variable is 3 the output should be 003.
Presently the syntax I am using is PRINT STR(@CLUSTER,3) . But if @CLUSTER which is numeric is less than three characters I get spaces in front.
Can anybody know ,how can we add builtin functions(ROW_NUMBER()) of Sql Server 2005 into database library. I get this error when i used into storeprocedure : ROW_NUMBER() function is not recognized in store procedure. i used MS SQL SERVER 2005 , so i think "ROW_FUNCTION()" is not in MS SQL SERVER 2005 database library. I need to add that function into MS SQL SERVER 2005 database library. Can anbody know how we can add that function into MS SQL SERVER 2005 database library?
I want to write function to call another function which name isparameter to first function. Other parameters should be passed tocalled function.If I call it function('f1',10) it should call f1(10). If I call itfunction('f2',5) it should call f2(5).So far i tried something likeCREATE FUNCTION [dbo].[func] (@f varchar(50),@m money)RETURNS varchar(50) ASBEGINreturn(select 'dbo.'+@f+'('+convert(varchar(50),@m)+')')ENDWhen I call it select dbo.formuła('f_test',1000) it returns'select f_test(1000)', but not value of f_test(1000).What's wrong?Mariusz

I want to run a sql script that creates some views using "osql". The views in turn refer to user defined functions which need a two-part name reference(MyUser.MyFunction). Is there a way to do this without hardcoding the value of the "MyUser" in the script?
Example..
I want to run a script called myscript.sql using OSQL. The file myscript.sql looks like this..
CREATE view V1 AS SELECT *, UserOwner1.MyFunction1(5) FROM MyTable go
CREATE view V11111 AS SELECT *, UserOwner1.ScalarFunction11111(7) FROM MyTable go
-----
I do not want to hardcode the username (UserOwner1) since it varies from database to database. So when I run this script from command prompt using "osql" I want the ability to supply the value for the username (UserOwner1) which owns the user defined function. How to do this?
This problem would go away if SQLServer 2000 was not so adamant about requiring two part reference to a user defined function.
I am sure this has been asked a thousand times before in a thousand different ways, but here goes...
I am in need of the ability to prompt users for a From Date and To Date to insert into a WHERE clause in SQL queries. What is the easiest least painful way of accomplishing this? A great many of our customers utilized SQL Server Express or MSDE, so they do not have the full gambit of SQL tools handy. Believe me when I say that I have searched high and low across the internet for this solution. I was hoping I might be able to accomplish this through VB Script or J Script. Or, anything reasonable.
Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't... I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it. So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need. Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like: DECLARE @table table@table=EXEC sp_pkeys MyTable That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great. Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out... SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT) Syntax Error. Ugh. Eventually, I even try: SELECT *FROM Split(substring('abc,def',2,6),DEFAULT) Syntax Error. Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function? SELECT *FROM Split('bc,def',DEFAULT) works just fine. So my questions are: Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it? Is there any way to pass a scalar-valued function as a parameter into a table-valued function? Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround: DECLARE @tmp varchar(8000) SET @tmp=(SELECT dbo.fn_pkeys('MyTable')) SELECT * FROM Split(@tmp,DEFAULT)
Yesterday Peso was gracious enough to help me with creating function/views/sp's
I took those examples and extended what had from excel into function in SQL
however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function?
Here are excerpts two functions I have:
We'll call this function UserUsage() ------------------------------------ RETURN( SELECT ut.LastName, ut.FirstName, CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)], Max(hu.time_stamp) AS [Last Log Date], pct.Title, cat.topic_name FROM ZSRIVENDEL.dbo.UserTable ut, ZSRIVENDEL.dbo.history_usage hu, ZSRIVENDEL.dbo.pc_CourseTitles pct, ZSRIVENDEL.dbo.cam_topics cat WHERE ut.student_id = hu.student_id AND hu.course_id = pct.CourseID AND hu.topic_id = cat.topic_id AND ((ut.ClientID=@ClientID) AND (pct.ClientID=@ClientID) AND (ut.GroupID=3400) AND (hu.time_stamp>= @StartDate And hu.time_stamp< @EndDate) AND (hu.session_time<21600000)) GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name )
and will call this function UserSummary(): ----------------------------------------- RETURN ( SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)] FROM ZSRIVENDEL.dbo.UserTable AS ut INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu ON hu.Student_ID = ut.Student_ID WHERE ut.ClientID = @ClientID AND ut.GroupID = 3400 AND hu.Time_Stamp >= @StartDate AND hu.Time_Stamp < @EndDate AND hu.Session_Time < 21600000 GROUP BY ut.LastName, ut.FirstName )
As you can see the first part of the both query are simlar. In particular the:
SELECTut.LastName, ut.FirstName, CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
and also the variables @StartDate and @EndDate.
In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?
