Using Conditional Statement In Stored Prcodure To Build Select Statement
Jul 20, 2005
hi
I need to write a stored procedure that takes input parameters,and
according to these parameters the retrieved fields in a select
statement are chosen.
what i need to know is how to make the fields of the select statement
conditional,taking in consideration that it is more than one field
added
for example
SQLStmt="select"
if param1 then
SQLStmt=SQLStmt+ field1
end if
if param2 then
SQLStmt=SQLStmt+ field2
end if
I am trying to allow a user the ability to search a database and select from various fields to search, such as Keywords and Filename. I tried building something like this: SELECT filenameFROM pictableWHERE (@searchby LIKE @searchwords) It allows me to enter the two varables (keywords and test), but returns no rows. If I simply replace @searchby with 'keywords' (ensuring no spelling errors), then I get a return of one row. So this works: SELECT filenameFROM pictableWHERE (keywords LIKE @searchwords) Can someone tell me what is going on? I have tried all sorts of quotes and parens to no avail. Thanks in advance.
Yet another puzzling question. I remember I saw somewhere a particular syntax to select a column based on a conditional predicate w/o using a user defined function. What I want to accomplish is this : SELECT (if column colA is empty then colB else colA) as colC from SomeTable. Possible ? Not possible? Have I hallucinated ?
I am trying to write a Transact-SQL statement and am having no success. I have a customers table that has some duplicate Customer Numbers in it, however the records do have a unique Reference Number. I am trying select all records that match a list of Customer Numbers but if there are more than 1 matching Customer Number I only want the one with the largest Reference Number.
My BASIC Select Statement is:
SELECT Cust_Ref_No, Customer_No, Customer_Name, Address1, Address2, Suburb, State, Postcode, Phone FROM Customers WHERE Customer_No IN (SELECT Customer_No FROM temp_Customers)
Much to my HORROR I found that what I am trying to do is simple in MS Access using the “First” Function – Such as below:
SELECT First(Cust_Ref_No) AS Cust_Ref_No, Customer_No FROM Customers GROUP BY Customer_No ORDER BY First(Cust_Ref_No), Customer_No;
There appears to be no “First” Function in Transact-SQL. Is someone able to show me how to achieve the same results in Transact-SQL as I can get with MS Access (I’d HATE to think that MS Access has more functionality in querying data than SQL Server in any way at all)?
P.S. I really need to run the select statement as one step rather than splitting it up into parts.
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 currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' FROM myTables WHERE Conditions are true ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' INTO AuxiliaryTable FROM myTables WHERE Conditions are true ORDER BY Field01 SELECT DISTINCT [Field02] FROM AuxTable The the results are:
Field02
----------------------
22810 8461760
And what I need is (without showing any other field):
Field02
----------------------
8461760 22810
Is there any good suggestion? Thanks in advance for any help, Aldo.
Hello friends, I want to use select statement in a CASE inside procedure. can I do it? of yes then how can i do it ?
following part of the procedure clears my requirement.
SELECT E.EmployeeID, CASE E.EmployeeType WHEN 1 THEN select * from Tbl1 WHEN 2 THEN select * from Tbl2 WHEN 3 THEN select * from Tbl3 END FROM EMPLOYEE E
can any one help me in this? please give me a sample query.
I have written a stored procedure which has in it a select statement. This returns a single record (I used the "top 1" line to ensure I only get a single record). I want to use a value returned by this statement (not the primary key) further on in the stored procedure - so assigning it to a variable would be handy.
Hi there, I am trying to return data from a select statement that is running a stored procedure.
I am running on SQL 2000 SP4. I have created a 'loopback' linked server as described in a technet article. (It's pointing at itself) I can then use the following select statement to get data back in the select statement from a stored procedure.
select * from openquery(loopback,'exec DWStaging.dbo.PokerStaging')
I am trying to get data back from my own Stored Procedure, but continue to get the following error:
Server: Msg 7357, Level 16, State 1, Line 1 Could not process object 'exec DWStaging.dbo.PokerStaging'. The OLE DB provider 'SQLOLEDB' indicates that the object has no columns. OLE DB error trace [Non-interface error: OLE DB provider unable to process the object:ProviderName='SQLOLEDB', Query=exec DWStaging.dbo.PokerStaging'].
If I try the same syntax with the sp_who stored procedure, it works and I get data back fine. But, If I try it with the sp_who2 stored procedure I get the same error as above.
select * from openquery(loopback,'exec sp_who') --> Works fine select * from openquery(loopback,'exec sp_who2') --> Doesn't work
Does anyone know what the difference is between the Stored Procedures that work with this syntax and those that don't? Is there a way I can change my stored procedure such that it would cause it to work?
PS: The following code was used to create the linked server, and then a security pass though as a certain account was addedDECLARE @provstr varchar (2000) SET @provstr = 'PROVIDER=SQLOLEDB;SERVER=' + @@SERVERNAME EXEC sp_addlinkedserver 'loopback', @srvproduct = 'MSSQL', @provider = 'SQLOLEDB', @provstr = @provstr
I have 3 tables, with this relation: tblChats.WebsiteID = tblWebsite.ID tblWebsite.AccountID = tblAccount.ID
I need to delete rows within tblChats where tblChats.StartTime - GETDATE() < 180 and where they are apart of @AccountID. I have this select statement that works fine, but I am having trouble converting it to a delete statement:
SELECT * FROM tblChats c LEFT JOIN tblWebsites sites ON sites.ID = c.WebsiteID LEFT JOIN tblAccounts accounts on accounts.ID = sites.AccountID WHERE accounts.ID = 16 AND GETDATE() - c.StartTime > 180
I have 5 drop down lists and 1 text box, and I need to build the WHERE portion of my SELECT statment (stored procedure). the drop down lists are named client, ptype, apptdate, inspdate, state, and the textbox is named text. they all need to be this=something AND that=another AND...AND text LIKE mytext. How would I go about building this efficiently? Would I Declare a bit value in the sp called WhereSet = 0 IF @client IS NOT NULL IF @WhereSet = 0 SET @Where = 'WHERE ClientID=@client' SET @SetWhere = 1 ELSE SET @Where = @Where + ' AND CleintID=@client' . . .... Or would this be a lot easier using adhoc SQL instead of a Stored Procedure? (note: I am using a SQL DataSource) Please help, I am going bald from pulling my hair our...

There is a stored-procedure that it has multiple select statements as returned result set. How can I use SqlCommand.ExecuteReader to get all result set?
What if the multiple select statements is " FOR XML", how can I set all xml using ExecuteXmlReader?
I tried to use ExecuteReader or ExecuteXmlReader, but seems that I can only get back the result set of the first select statement, all others are messed up.
stored procedure example: NorthWind database:
SET QUOTED_IDENTIFIER ON GO SET ANSI_NULLS ON GO
Create PROCEDURE dbo.getShippersAndEmployeesXML AS
select * from Shippers for xml auto, elements select * from Employees for xml auto, elements
RETURN @@ERROR
GO SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON GO
Is there a way to call a stored procedure within a SELECT statement?Example;-----------SELECT FirstName, LastName, (EXEC UniqueID_KEYGEN @keyval output) AS UniqueIDINTO #tNewEmployeeFROM EmployeeTable-----------SELECT *FROM #tNewEmployeeThe return from the temp table would have a unique ID ready to insert into another table. Our DBA has this stored procedure to create unique ID's and is to be used on all INSERTS. I was used to having a Identity field do this for me, I don't know why we have to do it his way. Except for the reason of sequence and easily get the next record. But we don't use URL variables, only FORM or SESSION.Thanks for your help in advance.
I have a stored procedure in an Informix-database that returns a string. Its used in a SELECT statement like this. SELECT t1.id, t2.id, sp_name(t1.id, t2.id) FROM table1 t1, table2 t2

Can a stored procedure be executed from within a select statement?
Given a store procedure named: sp_proc
I wish to do something like this:
For each row in the table execute sp_proc 'parameter1', parameter2'... end for ...but within a select statement. I know you can do this with stored functions, just not sure what the syntax is for a stored procedure.
I am trying to call a stored procedure inside a SQL SELECT statement. Has anybody had to do this in the past? I have a SELECT statement in a Microsoft Access database and I need that SELECT statement to call the stored procedure in the SQL server. Any help would be appreciated
Can this be done? I want to call a stored procedure from inside a select statement. Since you can nest select statements, I thought it might be possible but I have no idea how to do it.

I need to run a stored procedure on all the results of a select query.For a simplified example, I'd like to be able to do something likethis:SELECT JobID, QtyToAddFROM JobsWHERE QtyToAdd > 0Then for the results of the above:EXEC sp_stockadd @JobID, @QtyToAddWhere the above line ran for every result from the above select query.Anyone able to shed some light on how to do this?Many thanks,James
in my relational sql db structure I have some items and its children, grandchildren itemsto print these values do i need to build one sql statement for each tier?into my sproc i tried something as following but it returns me only the last tierSELECT * FROM AINNER JOINB ON A.field1 = B.field2INNER JOINC ON A.filed3 = C.field4WHERE A.filed1 = @myParam thanks a lot
Is it possible to have an entire sql select statement as the input variable to a stored procedure? I want the stored procedure to execute the select statement.
ie.
exec sp_SomeFunc 'select * from table1 where id=1'
It may sound weird, but I have my reason for wanting to do it this way. Is this possible? if so, how do I implement this inside the stored procedure?
If I run this statement in Query Analyzer, it properly returns 1for my testing table. But if I put the statement into a storedprocedure, the stored procedure returns NULL. What am I doingwrong? I suspect it may be related to how I defined the parametersfor the stored procedure. Perhaps my definition of TableName andColumnName don't match what COLUMNPROPERTY and OBJECT_ID expect toreceive, but I don't know where to look for the function declarationsfor those. Any pointers would be appreciated.Select statement:SELECT COLUMNPROPERTY(OBJECT_ID('Table1'), 'TestID', 'IsIdentity') ASIsIdentityTable definition:CREATE TABLE [dbo].[Table1] ([TestID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[Description] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]Stored Procedure definition:CREATE PROCEDURE spTest(@TableName varchar,@ColumnName varchar)AS SELECT COLUMNPROPERTY(OBJECT_ID(@TableName), @ColumnName,'IsIdentity') AS IsIdentity
