Using Case Expression In Exec SP Parameters

Jul 17, 2007

Hi,

 Maybe this is just totally wrong but this is what I'm trying to do.  I want to dynamically insert a value using a CASE expression while executing an external SP from my current SP.

 EXEC uspAddMessage @UserId,
CASE @MyAction
WHEN 'DELETE' THEN 'DELETED TRANSACTION.'
WHEN 'APPROVE' THEN 'TRANSACTION APPROVED.'
WHEN 'REJECT' THEN 'TRANSACTION REJECTED.'
END,
@DateStamp

 Keep in mind that this is in my stored proc that is doing the processing.  I'm calling this common proc when I complete my transactions.

 Thanks,

S

Problem Exec SP With Parameters In SQL Task

Jan 12, 2008

Hello,
I am trying to use an Execute SQL Task to execute a stored procedure with parameters in SSIS but it keeps giving me errors, for example I type in 'exec someproc ?, ?, ?' in SQL Task it wouldnt parse correctly and when I set the bypassPrepare to 'true' the package runs but gives me error at the destination saying couldnt find stored procedure 'someProc'.

Does anybody know how I can solve this problem?

Also how do I pass the results of the queries in the Execute SQL Task into the Data Flow Task? The proc is supposed to retrieve data and transform them into XML format to be placed at a XML file. I am not sure if I should used an OLEDB source or an XML source since the data has been transformed into XML. Any help will be greatly appreciated.

Problem With Case Expression

Sep 30, 2005

In the Portal1 case expression in the script at the bottom I would liketo replace where the result 1 is returned, with the substring functionreturned as Portal{SUBSTRING(Field1, CHARINDEX('tonep', Field1) + 4, (CHARINDEX('.txt',Field1) - 8) - (CHARINDEX('tonep', Field1) + 4))}However, I am experiencing errors. I think it is because The substringfunction will not return a number as the case expression expects so Imust incorporate cast or convert, but do not know how. Can you help???SELECT portal1 = CASE WHEN len(Field1) > 5 THEN 1 ELSE '' END,SUBSTRING(Field1, CHARINDEX('tonep', Field1) + 4, (CHARINDEX('.txt',Field1) - 8)- (CHARINDEX('tonep', Field1) + 4)) AS portal,Table.*FROM Table

Anyone know how to combine that into 1 expression? or is there away to work around it?
As I would like to display the month as Name, but group and sort by number.
Thx!~

Case Expression In SQL Server 2000

I have to use the Case expression in my query, so I search arround the web and got the following: SELECT title, price,        Budget = CASE price         WHEN price > 20.00 THEN 'Expensive'          WHEN price BETWEEN 10.00 AND 19.99 THEN 'Moderate'          WHEN price < 10.00 THEN 'Inexpensive'          ELSE 'Unknown'        END,FROM titles It should run OK base on my research in the internet. But my SQL Server gave me error: syntax error arround '>'.I did several search and many people can use the ">" sign or "<" sign in the Case expression, but I just can't use it in my SQL Server, I can't even use any boolean expression, I can only use values.can anyone help me out?

UPDATE Involving CASE Expression

Oct 25, 2007

I am one very frustrated beginner. If it were not for wonderful information in this forum I would have taken early retirement by now!

Table contains information about new and departing computer and phone users in several departments which we support. This is an existing table which I'm trying to clean up.
The essential part:

CREATE TABLE [dbo].[HelpDesk_NewUser](
[AutoNumber] [int] IDENTITY(1,1) NOT NULL,
[SubmittedDate] [datetime] NULL,
[FirstName] [varchar](100) NOT NULL,
[LastName] [varchar](100) NOT NULL,
[Department] [varchar](100) NOT NULL,
[StartDate] [datetime] NULL,
[DepartDate] [datetime] NULL
[RequestedBy] [varchar](100) NOT NULL,
[UpdatedBy] [varchar](16) NOT NULL,
[CurrentStatus] [varchar](10) NOT NULL ,
[DateCurrentStatus] [datetime] NULL,
[FormType] [varchar](10) NOT NULL,
) ON [PRIMARY]

There can be more than one record per FirstName, LastName. FormType can be N for new or D for departing.
I want to do this for each record:
Read the FormType and Department from the record with the most recent activity (SubmittedDate) for each user
Convert Department to a 4 character department number
Update CurrentStatus with (FormType concatenated with the 4 character dept number) in all records for that user.

I have created another table called UserMostRecent which contains the most recent record for each user.

I have written a query to do this by brute force (read a record, set local variables, update a record), but I would like learn a simpler way to do it. I don't understand the syntax of CASE because it seems to change depending on where it is used.

Here is what I have tried that does not work. Error is "Incorrect syntax near word CASE"

UPDATE HelpDesk_NewUser
SET DateCurrentStatus = b.DateMostRecent,
CurrentStatus = (b.FormType + a.Department
CASE
WHEN 'Roads Department' THEN '3000'
WHEN 'Engineering and Survey Services' THEN '1900'
WHEN 'Waste Management' THEN '8999'
WHEN 'Kern Air Pollution Control District' THEN '9149'
WHEN 'Environmental Health' THEN '4113'
WHEN 'Building Inspection' THEN '2625'
WHEN 'Animal Control' THEN '2760'
WHEN 'Planning Department' THEN '2750'
WHEN 'Community and Economic Development' THEN '5940'
WHEN 'Resource Management Agency' THEN '2730'
WHEN 'Code Compliance' THEN '2620'
WHEN 'Roads Kern Regional Transit' THEN '8998'
END)
FROM HelpDesk_NewUser a JOIN UserMostRecent b
ON (a.LastName = b.LastName and a.FirstName = b.FirstName)

Thank you, forum participants. You are the best!

Case Expression Within A Stored Proc

Jul 20, 2005

Is it possible? I have a request to create a stored proc that willdynamically add a range to a WHERE clause based on a numeric value of acomment type. If the incoming comment type request is say 10, thewhere clause needs to be set to IN(10,11,12,13,14,15,16,17,18,19)OR ifa 20 is passed in the clause would read IN(20,21.....)So I was thinking that a CASE expression within the proc would be thebest way to go, but have had no luck in finding an example or any otherrelated information regarding CASE exp in a proc.TIABill

Transact SQL :: CASE Expression In WHERE Clause?

Nov 6, 2015

I have a scenario where the End User is going to select two parameters.  @AgentID and @Location If the End User selects @AgentID parameter, in my WHERE clause, I do not want to check the location condition. By default, the agent knows their location already.

If the End User select @Location parameter, in my WHERE clause, I still want to check the Agent condition.

@AgentID parameter would populate either with "All" or their actual agent# (76754 for example).

@Location parameter would populate either with "All" or their actual location (Birmingham or Bessemer for example)Sample of my current WHERE clause:

WHERE
 
 gl.ReceiptDate >= @BeginDate and gl.ReceiptDate < DATEADD(D,1,@EndDate)
 AND gl.AgentId = CASE WHEN @AgentID = 'All' THEN gl.AgentID ELSE @AgentID END
 AND gl.Location = @Location

Execute Stored Procedure (with Parameters) With An Exec Command

Feb 21, 2004

Hi everybody, I would like to know if it's possible to execute a stored procedure, passing it parameters, using not CommandType.StoredProcedure value of sqlcommand, but CommandType.Text.

I tried to use this:
sqlCmd.CommandType = CommandType.Text
sqlCmd.Parameters.Add(sqlPar)
sqlCmd.ExecuteNonQuery()

With this sql command:
"exec sp ..."

I wasn't able to make it to work, and I don't know if it's possible.

Another question:
if it's not possible, how can I pass a Null value to stored procedure?
This code:
sqlPar = new SqlParameter("@id", SqlDbType.Int)
sqlPar.Direction = ParameterDirection.Output
cmd.Parameters.Add(sqlPar)

sqlPar = new SqlParameter("@parent_id", DBNull)
cmd.Parameters.Add(sqlPar)

doesn't work, 'cause I get this error:
BC30684: 'DBNull' is a type and cannot be used as an expression.

How can I solve this?
Bye and thanks in advance.

P.S. I would prefer first method to call a stored procedure ('cause I could call it with 'exec sp null' sql command, solving the other problem), but obviusly if it's possible...=)

Sorry for grammatical mistakes.

Converting A String Expression To Proper Case

Oct 22, 2000

How would I convert an expression like on of these to all upper case first letters with remaining letters lower case? VB has a function for that but sql doesn't seem to. I thought about having a loop go through each character to check for spaces. I've written a couple of similar pieces of code in VB when a while ago, but is there a better way? Thanks :)

Just a couple of typical examples of how the data should appear ~

payment, credit card ==> Payment, Credit Card
butcher & singer ==> Butcher & Singer

Case Expression Plus Outer Join In Ole Db Source

Oct 26, 2006

I'm trying to generate the data for a 2-column table, where both columns are defined as NOT NULL and the second column is a uniqueidentifier.

In SQL Server Management Studio, this works fine:insert into table_3(column_a, column_b)
select table_1.column_a, (case when table_2.column_b is NULL then newid() else table_2.column_b end) as column_b
from table_1 left outer join table_2 on table_1.column_c = table_2.column_c


That is, column_b of the SELECT result has no NULL values, and all 35,986 rows are successfully inserted into a previously empty table_3. (If I comment out the INSERT INTO clause and project table_2.column_b instead of "(case ... end) as column_b", the SELECT result includes 380 rows with a NULL in column_b, so I know the case expression plus the outer join are working as expected.)

But when I use the SELECT query as the SQL command in an OLE DB Source component that is connected directly to the OLE DB Destination for the result table, I get this error:There was an error with input column "column_b" (445) on input "OLE DB Destination Input" (420
The column status returned was: "The value violated the integrity constraints for the column.".


And sure enough, when I modify the result table to allow NULL in column_b, truncate it, and re-run the data flow, it inserts the exact same 380 rows with a NULL in column_b among the 35,986 rows.

So what is SSIS doing to screw up the results of the SELECT command???

Error Using Case Expression In Order By Statement

Feb 22, 2008

I have been trying to get the following Selects to work using a case expression in the order by section.

I know I can easily separate out the two statements but I want to do a select using the case statement below ;
however, I keep getting error 16 --"Order by items must appear in the select list if the statement contains a union.

If remove the case statement and put order by "internalID desc" I receive no errors. Moreover, when I take out the union statement and execute the two select statements with each including the case expression it runs as planned.

Can anyone tell what the problem is here? I have combed the web looking for an answer, but it seems that the statement is valid.


Thanks
J
declare @date
set @date = '2001'



select internalID from section_data_v3

select internalID from section_data_v4

How do you make the "Like" comparison operator ignore case in an expression??

Expression looks like this:




Code SnippetParameters!CompanyFilterOp.Value = "%",Fields!company.Value like "*" & Parameters!Company.Value & "*"





BTW, the expression above is part of a switch expression, and is at the table level.

Data contains "General Industry" in Company column from database.

User enters "indust" in Company Parameter text box, and result is no data found.

User enters "Indust" in Company Parameter text box, and data is returned.

SELECT Query Including JOIN And CASE Expression

Aug 12, 2012

An error is entered into the table, across two tables - tblErrors_ER and tblPolicyNumbers_ER - each error generates a PK (ErrorID) and can have any number of policy numbers which will be referenced by its own PK but linked to each error by its FK (ErrorID).I want to display each error in a Gridview in ASP.Net - columns included will be ErrorID, ErrorType, DateLogged from tblErrors_ER and PolicyNumber from tblPolicyNumbers_ER.If an Error has more than one policy number I only want to show the error once in the GridView with the word MULTIPLE under policy number.

tblErrors_ER
---------------
CREATE TABLE tblErrors_ER
{
ErrorID int,
ErrorType varchar(255),
DateLogged datetime,

[code]...

I have changed the Count(*) to Count(tblPolicyNumbers_ER.POlicyNUmber) which gives me the same undesired result as above. I have also left it as Count(*) and the entire CASE expression within the GROUP BY statement as suggest above which generated an error saying I can not use an expression in a group by clause.

If I leave Count(*) = 1 where it is in the original SELECT statement but swap the = for > then something happens, close to what I require but not as intended. It returns:

ErrorID ErrorType DateLogged PolicyNumber
---------------------------------------------------------------
1 Test 08/08/2012 Multiple
2 Test 08/08/2012 Multiple

this would suggest the original syntax is close to being accurate but I can not get it to work.

Wrong Evaluation Of A Variable With Expression In Case It Is Used Simultaneously By Several Tasks

Aug 22, 2007



Hi guys,

I have experienced problem while trying to use variable with expression based on several other variables in tasks running parallel.

The details are as following:

There is a SSIS package with simple Control flow: one Script Task which actually do nothing and two Execute Process Tasks, they run after Script Task in parallel. Then there are three simple (EvaluateAsExpression = False) string variables ServerName, Folder and JobNumber with values ServerName = €œ\test€?, Folder = €œtest€? and JobNumber = €œ12345€?. And there is one variable FullPath with expression @[User:: ServerName] + "\" + @[User::Folder] + "_" + @[User::JobNumber]. All the variables are of the Package scope. Then in Execute Process Tasks I have similar expressions based on FullPath variable: Execute Process Task 1 has expression @[User::FullPath] + "\date.bat" and Execute Process Task 2 has @[User::FullPath] + "\time.bat" one. As you understand these expressions define what exactly task should execute.

Then I€™m going to execute package from command line so appropriate XML configuration file has been created. The file contains following values for variables described above: ServerName = €œ\LiveServer€?, Folder = €œJob€? and JobNumber = €œ33091€?.

After series of consequent executions I have got following log file:

€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\Test est_12345date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\Test est_12345 ime.bat€?



€¦ Execute Process Task 1€¦ Executing the process €œ\LiveServerJob_33091date.bat€?

€¦ Execute Process Task 2€¦ Executing the process €œ\LiveServerJob_33091 ime.bat€?



€¦



As you can see one of Execute Process Tasks usually receive correct value of the expression (based on values of variables from the configuration file) while another - incorrect one (based on €œdefault€? values of variables set directly in package). Sometimes wrong value appears in Task 1, next time in Task 2. Situations when both expressions in tasks evaluated correctly are very rare.

Then if you add some more Execute Process Tasks with similar expressions in the package (for ex. simply by copying existing tasks) you€™ll get a good chance to catch error like this:



OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073450774,0x,Reading the variable "User::FullPath" failed with error code 0xC0047084.



OnError,,,Execute Process Task 1,,,8/17/2007 2:07:12 PM,8/17/2007 2:07:12 PM,-1073647613,0x,The expression "@[User::FullPath] + "\time.bat"" on property "Executable" cannot be evaluated. Modify the expression to be valid.



Seems variable with expression FullPath is locked during evaluation by one of the parallel tasks in such a way that another task can€™t read it value correctly. Can someone help me with the issue? Maybe there are some options I missed which could prevent such behavior of application? Please let me know how I can make the package work correctly.

Newbie Case/search Question In Derived Column Expression Syntax

Feb 6, 2008



Hi everyone,

I am a newbie to SSIS and looking for answer to a simple search/replace style question.

I am building a derived column and looking for some expression syntax that can search for several strings in one column and set a value in a new column.

A bit like a case statement:

CASE ProductLine
WHEN 'R1' THEN 'Road'
WHEN 'M1' THEN 'Mountain'
WHEN 'T1' THEN 'Touring'
WHEN 'S1' THEN 'Other sale items'
ELSE 'Not for sale'
END,


The twist is that 'R1','M1','T1','S1' could feature anywhere in the string that is ProductLine.

Thanks for all your help,

regards,

Chris

Sub-report Visibility By Expression With Two Conditions Based On Parameters

May 30, 2007



Product version : SQL Reporting Service 2005 with SQL SP2



It's a report with 3 sub-reports in it, i want to display only one of the 3 sub-reports at a time depending on 1 or 2 parameters received by the parent report. These parameters are verified by an expression into the visibility tab of each sub-report. The two parameters are 2 lists with possibles values between 1 and 2 (not query based). I have verified these values and they are correctly received by report depending on the selection of each list.



Ex.: SubReport1.expression = IIf(Parameters!Regroupement.Value = 1, True, False)



SubReport2.expression =IIf(Parameters!Regroupement.Value = 2 AND Parameters!SautPage.Value = 1, True, False)



SubReport3.expression =IIf(Parameters!Regroupement.Value = 2 AND Parameters!SautPage.Value = 2, True, False)



So here are the posibilities :

when Regroupement.Value = 1 --> SubReport1 will be shown



when Regroupement.Value = 2 AND SautPage.Value = 1 --> SubReport2 will be shown



when Regroupement.Value = 2 AND SautPage.Value = 2 --> SubReport3 will be shown



Now why that doesn't work ? I always see the same report and it's not the right one displayed even i change the selection of my 2 lists for the parameters value.

Newbie Search/replace Case Style Functionality In Derived Column Expression Syntax

Hi guys,

I am looking for some syntax to help me with a traditional search/replace style requirement. I am wanting to examine the contents of one column and populate another.

similar to this SQL case statement

WHEN 'R1' THEN 'Road'
WHEN 'M1' THEN 'Mountain'
WHEN 'T1' THEN 'Touring'
WHEN 'S2' THEN 'Other sale items'
ELSE 'Not for sale'
END,


the twist is that R1, M1 etc. can appear anywhere in the ProductLine column.

thanks for any assistance you can provide.

Where Clause To Use Case W/ Parameters

Feb 1, 2007

I have my where clause as follows, but it's not working:

WHERE (WPID LIKE @WBS1 + '.' + CASE WHEN @WBS2 = '' THEN substring([Number], 4, 2) = __ ELSE substring([Number], 4, 2) = @WBS2 END CASE)

I give the user two paramters.

The first parameter is to populate the first two characters of a string. There is a "." then another two characters. What I'm trying to do is if the user types nothing in the second parameter, then I use the underscore characters so it can be any two characters. If they do enter two characters, then I want to use them for the 2nd part of the string, hence character 4 and 5.

EXEC Inside CASE Inside SELECT

Nov 16, 2007

I'm trying to execute a stored procedure within the case clause of select statement.
The stored procedure returns a table, and is pretty big and complex, and I don't particularly want to copy the whole thing over to work here. I'm looking for something more elegant.

@val1 and @val2 are passed in


CREATE TABLE #TEMP(
tempid INT IDENTITY (1,1) NOT NULL,
myint INT NOT NULL,
mybool BIT NOT NULL
)

INSERT INTO #TEMP (myint, mybool)
SELECT my_int_from_tbl,
CASE WHEN @val1 IN (SELECT val1 FROM (EXEC dbo.my_stored_procedure my_int_from_tbl, my_param)) THEN 1 ELSE 0
FROM dbo.tbl
WHERE tbl.val2 = @val2


SELECT COUNT(*) FROM #TEMP WHERE mybool = 1


If I have to, I can do a while loop and populate another temp table for every "my_int_from_tbl," but I don't really know the syntax for that.

Any suggestions?

which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.

URGENT - My Error Or Bug? The Result Of The Expression Cannot Be Written To The Property. The Expression Was Evaluated, But

Feb 8, 2007

Error 3 Error loading MLS_AZ_PHX.dtsx: The result of the expression ""C:\sql_working_directory\MLS\AZ\Phoenix\Docs\Armls_Schema Updated 020107.xls"" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property. c:documents and settingsviewmastermy documentsvisual studio 2005projectsm l sMLS_AZ_PHX.dtsx 1 1


"C:\sql_working_directory\MLS\AZ\Phoenix\Docs\Armls_Schema Updated 020107.xls"

Directly using C:sql_working_directoryMLSAZPhoenixDocsArmls_Schema Updated 020107.xls
as connectionString works

However - I'm trying to deploy the package - and trying to use expression:
@[User::DIR_WORKING] + "\Docs\Armls_Schema Updated 020107.xls"
which causes the same error to occur

(Same error with other Excel source also:
Error 5 Error loading MLS_AZ_PHX.dtsx: The result of the expression "@[User::DIR_WORKING] + "\Docs\Armls_SchoolCodesJuly06.xls"" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property. c:documents and settingsviewmastermy documentsvisual studio 2005projectsm l sMLS_AZ_PHX.dtsx 1 1
)
