Transact SQL :: Pass Filenames To A Loop
Aug 27, 2015
I’m working on building a file list from a directory I have and wish to loop through the filenames. I’ve worked out I can get the list using
EXEC
xp_dirtree @path, 10, 1
I’m just not sure out I pass this to my loop 1 element at a time.
E.g. Let’s say there are 10 files in my folder, I wish to loop through each name using my @Filename parameter
DECLARE @Path
varchar(50), @FileName
varchar(20)
SET @Path
= 'C:myFiles'
EXEC
xp_dirtree @path, 10, 1
[Code] ....

Hi,
I am using a foreach loop to go through the .txt files inside a folder.
Using a variable I can pickup the filenames the loop is going through.
At present there is a sql task inside the foreach loop which takes the filename as a parameter and passes this filename to a stored procedure.
Now I would like to add one extra step before this sql task. Would like to have a dataflow with flatfile source which connects to oledb destination.
The question is:
While in the loop, how is it possible to pass the filename to the flatfile source using the FileName variable which I have created?
Please note, this is a different question to my other post.
Many Thanks

Hello
I want to use a for each loop container to go through all files listed in a particular folder.
Each of those file names must be passed as a parameter to the relog.exe command utility
example:
Folder C: emp
Files in C: emp: log1.csv, log2.blg, log3.txt
The following lines must be executed:
c:
elog.exe c: emplog1.csv -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog2.blg -f SQL -o "SQL:PerfCounters!PerfCounters"
c:
elog.exe c: emplog3.txt -f SQL -o "SQL:PerfCounters!PerfCounters"
The relog utility converts the performance counter logs to sql format and pumps it in the database (DSN:PerfCounters)
The idea is that someone drops multiple counter logs in c: emp and you start a SSIS package to pump the data from all the files in the database.
I'm not sure where to start. Do I have to put a Script task inside the For Each loop container en start scripting the commands in Visual Basic.Net or is there a more simpler way to achieve this in SSIS?
Many thanks!

I have a multiselect checkbox list in my UI. I pass the list items to my stored proc as comma separated parameter and then I have a function which converts this parameter to a table with separate rows.
E.g. : a,b,c,d
Converted to result table
result
a
b
c
d
I want to insert each row of the result table into another table. How to do that.
E.g., the table after the function is :
CREATE TABLE #result
(
Subject varchar(100)
)
insert into #result values ('a')
insert into #result values ('b')
insert into #result values ('c')
insert into #result values ('d')
So the pseudo code is something like
for each row in #result
insert row into another table

In some t-sql 2012 that I am using, I am using the following on 5 separate merge statements.
USING
(select LKC.comboID,LKC.lockID,LKC.seq,A.lockCombo2,A.schoolnumber,LKR.lockerId
from
[LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
[Code] ...
What is different, is the value of LKC.seq = 1 as listed below. I am using 5 separate ctes and the only value that changes is the LKC.seq number being a value between 1 and 5. Thus can you pass a parameter value to the CTE that I just listed above? If so, show t-sql to accomplish this goal?

set @SITE_ID=1
set @txtSchedule='5,6'
select * from Schedules WHERE SITE_ID=@SITE_ID and WEEK IN(@txtSchedule .

Below is the query for my procedure
ALTER PROC [dbo].[sp_GetInvitationStatusTest]
(
@invited_by NVARCHAR (50)

AS
BEGIN
-- SELECT * FROM dbo.Merck_Acronym_Invitations WHERE invited_by=@invited_by
select distinct t1.invited_isid as 'ISID', t1.invited_name as 'NAME',t1.invitation_status as 'STATUS',
[Code] ....
If you look at the where clause i have invited by , i get the desired output if i just provide 1 name in the execution such as exec [dbo].[sp_GetInvitationStatusTest] 'marfilj' But my requirement is to make the procedure work with more than one input variable such as exec [dbo].[sp_GetInvitationStatusTest] 'marfilj','sujith' now i should get the output for 2 people but if i run this i receive the following error Procedure or function sp_GetInvitationStatusTest has too many arguments specified.
how to make my procedure work with more than 1 input variable?

My insert statement for #Data - I only need to process each @EmployeeID one time, which is why I thought a loop would be sufficient, but I let this process run for 2 hrs and it still had not completed, so I feel I must have set-up something incorrectly!
This is my syntax, I am creating a table of active users, then wanting to get data for each of those active users. But only get the data for each active user 1 time.
Declare @EmployeeID varchar(50)
CREATE TABLE #ActiveUsers

ID INT IDENTITY NOT NULL

I have a Stored Procedure, wherein I need to use a while loop. essentially the loop looks like this.
Set @Kount = 1
--TestScript
Select 'TempReqTable', * from @TempReq
WHILE Exists(Select * from @TempReq WHERE TempID = @Kount)
BEGIN
--Do stuff with values from table
Set @Kount += 1
END
The test script confirms that there is only one row in the @TempReq table. However the loop never stops running and @Kount keeps being incremented and incremented until I manually stop the execution of the SP.
Is there some rule that I am not aware of that does not allow the use of an Exists statement in the condition of a While loop?

I appear to be having an issue where the @LetterVal and @Numeric variables aren't resetting for each loop iteration, so if no results are found, it just returns the previous loops values since they aren't overwritten. Below is the stored procedure I've created:
ALTER PROCEDURE [dbo].[ap_CalcGrade]
-- Add the parameters for the stored procedure here
@studId int,
@secId int,
@grdTyCd char(2),
@grdCdOcc int,
@Numeric int output,
[Code] ....
And below is the "test query" I'm using:
-- *** Test Program ***
Declare @LetterVal varchar(2), -- Letter Grade
@Numeric int, -- Numeric Grade
@Result int -- Procedure Status (0 = OK)
Execute @Result = dbo.ap_CalcGrade 102, 86, 'QZ', 3,
[Code] ....
This is resulting in an output of:
A+ 97
A+ 97
C- 72
but it should be returning the output below due to the 2nd data set not being valid/found in the sp query:
A+ 97
No Find
C- 72
I'm sure this is sloppy and not the most efficient way of doing this, so whats causing the errant results, and if there is any better way I should be writing it. Below is the assignment requirements:
Create a stored procedure using the STUDENT database called ap_CalcGrade that does the following:
1. Accepts as input STUDENT_ID, SECTION_ID, GRADE_TYPE_CODE, and GRADE_CODE_OCCURRENCE
2. Outputs the numeric grade and the letter grade back to the user
3. If the numeric grade is found, return 0, otherwise return 1
4. You must use a cursor to loop through the GRADE_CONVERSION table to find the letter grade

I have 3 tables: Suppliers, Documents and Verification, each document may have multiple verification where I need to get the last verification according to verification date. So I just need a "Select top 1 result from Documents, Verification where doc_iddoc=ver_iddoc and result='True' order by ver_date desc" so far I get the result of the last verification, but here's the problem:
I need to get a row with the count of documents for each supplier, I mean:
Supplier Name Docs NegativeVerification
Acme Co 10 1
that is I would need to loop for each supplier and each document and get the last verification, if one of any of documents have negative verification then add it to negative results. Is it possible to achieve this with a query or do I have to do it through stored procedure?

I have a dynamic sql query where in I am comparing two tables and loading data for last 15 days. e.g today 2050921 then I am going to load till 20150906.
I pass on 2 variables @currentdate and @currentdate-1 to the query which are in date format 'yyyymmdd'
I need to do this for last 15 days how do I do this using while loop.
Note my date format is YYYYMMDD.
DECLARE @SQL VARCHAR(MAX)
@sql = ' insert into target
select from table_1_currentdate a
LEFT JOIN Table_2_currentdate-1 b
on a.col1=b.col1 where b.col1 is null '
exec(@sql)

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'm using SQL2005 and need to script a bunch of Tables (and possibly other objects) to files. I can't make one big file with all the objects in it. I need to create an indiviual file for each object and each filename needs to be something like dbo.objectname.sql. I will be checking each file (object script) into VSS. Can someone tell me how to do this withouth having to manually generate a script for each object? Is there a way to check each object you want scripted and the SSMS spit out a file per object?

I was wondering if it is possible to create a variable that holds the filename as an expression. I am using a For each loop to pick up files and i want to insert the 'Filename' as a colum in to the destination Table so that i can differentiate among the rows in my destination Table.
Using the 'Derived Colum' in DTS I can link the colum to a variable. However i do not know how to create the variable which will dynamically store the filename for each file....
Any Clues...
Would really appreciate the help.....
Or is anyone knows any other simple way of inserting the filename as a column in the destination Table ...Been stuck on this for a while...
