How To Call A Function From A Column Formula In My MS SQL Table
Apr 24, 2007
Good day!
What is the syntax on calling a function from a column formula in an MS SQL table.
I created a table, one column's value will be coming from a function. And at the same time, I will pass parameters to the function. How do I do this? Is this correct?
SELECT dbo.FunctionName([Parameter1, Parameter2])
But i can't save the table, "Error validating the formula".
I am trying to figure out how to set the Description of a Column in my database table by making a SQL function call. I know that I can go into Microsoft Studio Express and type in each desciption for each column. I just have about 1000 variables and each variable's description is in an Excel spreadsheet. I want to be able to build SQL code that will set each of the 1000 variables own description.
Hi,I'm on SQL Server 2000, say, I have a table named [orders], how I findif there is any column which has a formula in it? In other words, howto identify formula column programmatically? I've looked atinformation_schema.columns view for clue but to no avail.Thanks.
Hi all, I want to use a function with a tabel object as parameter. Doessomeone know a method to do this. I have read that a table as parameteris invalid.
I'm trying extract a column from the table based on certain Conditions: This is for PowerPivot.
Here is the scenario:
I have a table "tb1" with (project_id, month_end_date, monthly_proj_cost ) and table "tb2" with (project_id, key_member_type, key_member, start_dt_active, end_dt_active).
I would like to extract Key_member where key_member_type="PM" and active as of tb1(month_end_date).
How to call a table valued functions from SSRS reports ?
Is there a way to call by selecting Dataset properties> Query >Stored Procedure radio button, If not then why our object type function is visible under this list.
This function computes the great circle distance in Kilometers using the Haversine formula distance calculation.
If you want it in miles, change the average radius of Earth to miles in the function.
create function dbo.F_GREAT_CIRCLE_DISTANCE ( @Latitude1 float, @Longitude1 float, @Latitude2 float, @Longitude2 float ) returns float as /* fUNCTION: F_GREAT_CIRCLE_DISTANCE
Computes the Great Circle distance in kilometers between two points on the Earth using the Haversine formula distance calculation.
Input Parameters: @Longitude1 - Longitude in degrees of point 1 @Latitude1 - Latitude in degrees of point 1 @Longitude2 - Longitude in degrees of point 2 @Latitude2 - Latitude in degrees of point 2
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
HI,I have a problem in formula column.I have 8 1 bit varibles in a tablefor ex: Flag1, falg2, flag3 ...Flag8Now I want to create another variable as a small integer and copy allthe flgas to that field.For ex:(flag1 << 0x80) | (flag2 << 0x40) | ..... | flag8I tried all possible ways?Let me know how to write the formula for this column.Thanks,Venkat.
Hi,I would like to create a calculated column using the formulasection for a table. I am having some trouble doing this.The table's name is ReportParameter. The calculated column's name istbcalculatedcolumn and tb1 and tb2 are boolean columns in the table.I would like to use an If then statement such as the following (inpsuedo code):If tb1 = 1 then tbcalculatedcolumn = 1Elseif tb2 = 1 then tbcalculatedcolumn = 2EndifThanks for the help,Bill
Hi,I'm struggling to get a calculated column to work in sql, the fields to be calculated are:[AdRevenue_a] money[Admissions_a] int[DoorPrice_a] smallmoney[DoorSplit_a] moneyAnd the calculation I require is:(AdRevenue_a / ( (Admissions_a * DoorPrice_a) - DoorSplit_a )) * 100This is what I think it should be but it doesn't work...convert(decimal(6,2), ((AdRevenue_a / ((Admissions_a * DoorPrice_a) - DoorSplit_a))*100) ))Any suggestions??
I have downloaded the SQL Server Books online and found the section on Computed columns. In my small banking program I have columns named Deposit/Withdrawel and Balance. If I am reading this right I need to set the Computed Column Specification of my Balance Column in order to perform the calculation. My problem now is that I have no idea how to word the formula and other than telling me what a formula is the SQL Server Books online is no help whatsoever, so any help would be awesome.
If i've misunderstood what I am meant to do somebody please please tell me. Thanks
I am trying to do the following. While inserting a record into a table I need one field to be created based on a stored procedure output.The stored procedure will create something like this, "XX-mm-yyyy-incremental number which resets to zero at the end of every month". All other field except the Identity field and the above mentioned storeproc generated field will be inputted manually. How can I do this? Thanks Hope my question is clear enough.
Is it possible to retrieve the formula associated with a computed column using t-SQL? I can use COLUMNPROPERTY( id, column, 'IsComputed') to find the computed columns, but how do I get the formula itself?
It works in a straight select query, but when I put it in the formula of the table design window, I get an error "Error validating the formula for column 'test_fci'"
I don't know if it's relevant but repl_value is itself a computed column with the formula:
(repl_value_e_g + repl_value_aux)
Is it possible to use the system functions in a computed column? If not, how would I pass those values into a udf and use it for the formula?
I'm trying to replicate client data from multiple databases into a single table. So database A, B and C replicate client data to a table in database Z. There is a settings table on A, B and C that holds the businessID and I use a function in a computed column to add this to the client table. At the moment I have just database A and Z as a test and what happens is the computed column gets replicated as a computed column with the formula.
Can I change this so that I can replicate the computed value (at db A,B,C) of this column?
I don't really want to add a businessID to the table if possible as I'm going to need to add a number of other tables to this replication which will each need to have the businessID, a computed column would be much easier and save updating a load of scripts.
If the above is not possible is there some other solution available so I can identify which database the records came from in the table on database Z?
I have written a simple DAX calculated column formula using SEARCH and got an error: It tells the text "PWP" cannot be found but as you can see the screen shows this text exsist within "Promotional Claim"The same happens when I try FIND function.
Hi,I'm sure this is a common problem.. to create a single field from awhole column, where each row would be separated by a comma.I can do this for a specified table, and column.. and I've created afunction using VBA to achieve a more dynamic (and very slow) solution..so I would like to implement it using a user defined function in sql server.The problems I'm facing are, that I can't use dynamic sql in afunction.. and I also can't use temporary tables which could build up a'standard' table from parameters given to then perform the function on.So, with these limitations, what other options do I have?Cheers,Chris
I'm running 2014 enterprise and getting an error on this form of a query...it says the multi part identifier "mns.col3" could not be bound. I'm aware that a cross apply would be more appropriate but i'm just prototyping and probably going to move to a set based approach anyway.The udf returns a table.
select mns.col1, mns.col2 from table1 mns left join dbo.udf_udf1(@firstofmonth,@lastofmonth, mns.col3) x on 1=1
Can someone help me to understand a stored procedure I am learning about? At line 12 below, the code is calling a function named"ttg_sfGroupsByPartyId" I ran the function manually and it returns several rows/records from the query. So I am wondering? does a call to the function return a temporary table? And if so, is the temporary table named PartyId? If so, the logic seems strange to me because earlier they are using the name PartyId as a variable name that is passed in.
1 ALTER PROCEDURE [dbo].[GetPortalSettings]2 (3 @PartyId uniqueidentifier,45 AS6 SET NOCOUNT ON7 CREATE TABLE #Groups8 (PartyId uniqueidentifier)910 /* Cache list of groups user belongs in */11 INSERT INTO #Groups (PartyId)12 SELECT PartyId FROM ttg_sfGroupsByPartyId(@PartyId)
I made an SQL function in MSSQL2000. This is a function that get's a calculated heat emission. When I run the Query in MSSQL2000 the function works. It calculates every emission for every row. When I call this SQL function in VS2005, it says it does not recognize the function. Does anyone know what this may cause? thank you. For the people who are bored, I added the SQL statement. The error is at the function
SELECT TOP 15 tbProducts.prod_code, tbProductProperties.prop_height, tbProductProperties.prop_length, tbProductProperties.prop_type, tbProductProperties.prop_default_emission, tbProductProperties.prop_weight, tbProductProperties.prop_water_volume, tbProductProperties.prop_n_value, GetHeatEmission(50,70,20,[prop_default_emission],[prop_n_value]) AS customEmission FROM tbProductClassification INNER JOIN tbProducts ON tbProductClassification.clprod_fk_prod_id = tbProducts.prod_id INNER JOIN tbProductProperties ON tbProducts.prod_id = tbProductProperties.prop_fk_prod_id WHERE (tbProductClassification.clprod_fk_class_id = 3327) AND (prop_height >= '030') AND (prop_height = '060') AND (prop_length
select centerid from GetChildCenter(@Centerid) union select centerid from getParentCenter(@Centerid) } as Center c
on c.Centerid = client.Centerid
Query 2
declare @Center table ( centerid int) insert into @Center
select centerid from getchildCenter(@Centerid) union all select centerid from getparentcenter(@Centerid)
Select Clinetid from clinet inner join @Center c on c.Centerid = client.Centerid
I just want to know which one is better performance wise.. because there is millions of rows for table center which is used by function getChildCenter() and GetparentCenter()
