hello,
I'd like to know how I can grab the output of the following code and use it as variable:
declare @sql nvarchar(25)
set @sql = 'SELECT CURRENT_TIMESTAMP'
EXEC(@sql)
Thank you.
I know this has been dealt with a lot, but I would still reallyappreciate help. Thanks.I am trying to transform this tableYY--ID-Code-R1-R2-R3-R4...R402004-1-101--1--2-3-42004-2-101--2--3-4-2....2005-99-103-4-3-2-1Into a table where the new columns are the count for 4-3-2-1 for everydistinct code in the first table based on year. I will get the yearfrom the user-end(Access). I will then create my report based on theinfo in the new table. Here's what I've tried so far (only for 1stcolumn):CREATE PROCEDURE comptabilisationDYN@colonne varchar(3) '*receives R1, then R2, loop is in vba access*ASDECLARE @SQLStatement varchar(8000)DECLARE @TotalNum4 intDECLARE @TotalNum3 intDECLARE @TotalNum2 intDECLARE @TotalNum1 intSELECT SQLStatement = 'SELECT COUNT(*) FROMdbo.Tbl_Réponses_Étudiants WHERE' + @colonne + '=4 AND YY = @year'EXEC sp_executesql @SQLStatement, N'@TotalNum4 int OUTPUT', @TotalNum4OUTPUT INSERT INTO Comptabilisation(Total4) VALUES (@TotalNum4)GO
View 6 Replies View RelatedI have a procedure that executes a sql statement passed in as a parameter. The parameter variable is
@pSqlStatement.
CREATE PROCEDURE [dbo].[ProcedureTest]
@pSqlStatement nvarchar(4000)
AS
BEGIN
DECLARE @retVal int;
BEGIN TRY
EXECUTE sp_executesql @pSqlStatement, N'@ret int OUTPUT', @retVal OUTPUT;
PRINT 'try @retVal = ' + ISNULL(CAST(@retVal AS varchar), 'null');
END TRY
BEGIN CATCH
PRINT 'catch @retVal = ' + ISNULL(CAST(@retVal AS varchar), 'null');
END CATCH;
END;
Here is an example of this procedure being called:
EXECUTE [dbo].[ProcedureTest]
@pSQLStatement = N'EXECUTE @ret = [log].[Log.SetSeverityLevel] 'debug'
Note that in the sp_executesql statement, the @ret variable from the dynamic SQL gets assigned to the local variable @retVal.
Here's the problem; when the procedure [log].[Log.SetSeverityLevel] that gets dynamically executed does a RAISERROR, the code in [dbo].[ProcedureTest] falls through to the catch block in [dbo].[ProcedureTest] as it should, but the value of @retVal is null in the catch block, when the return code in [log].[Log.SetSeverityLevel] is set to -1.
If you comment out BEGIN TRY / END TRY / BEGIN CATCH / END CATCH in [dbo].[ProcedureTest], the value of @retVal is correctly seen as -1. There's something about the TRY CATCH structure that's blowing away @retVal when an error is raised and it falls through to the CATCH block.
Anybody ever seen this before? Is there a workaround?
Thanks - Dana
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.
I have a long running trigger that makes calls to several tables in order to get values for a list of parameters before doing my final INSERT statement into a different table.
One of my parameters is for a local language translation of a particular word which is stored in a table. The problem is - I do not know the name of the table until runtime when I dynamically build the name as follows:
DECLARE @SQL nVarChar(200)
SET @SQL = 'SELECT @Translation = nvcLocalEventDescription FROM Monitoring.dbo.tblSignalTemplate'
+ CAST(@MonitoringCentreID AS nVarChar) + ' WHERE nvcEventDescription = "' + @EventDescription + '"'
EXECUTE Management.dbo.usp_parmsel_LocalEventDescription @SQL, @LocalEventDescription OUTPUT
If there is a MonitoringCentreID of 1234, then there will be a table named tblSignalTemplate1234 - which will contain a nvcLocalEventDescription field containing the value that I am after. Here is the code for the stored procedure...
CREATE PROCEDURE [dbo].[usp_parmsel_LocalEventDescription]
@strSQL nVarchar(150),
@Translation nVarChar(100) OUTPUT
AS
EXECUTE sp_executesql @strSQL
GO
The error I get is "Must declare the variable '@Translation'" - which has thrown me a little as it declared on the 3rd line of the stored proc.
Anyone got any ideas where I am going wrong, or as usual, is there a simpler way ?
Steve.
Hi:
Can anyone tell me if it's possible in SQL Server 2000 to build dynamically a select statement and get some values to variables (simple not tables) from the select ?
Thanks,
Rui Ferreira
I am having a bit of trouble writing a query that dynamically outputs what I need.
I have a table that looks like this:
COL1 AAA BBB CCC
CAT 1 3 3
CAT 1 2 2
CAT 1 4 4
DOG 2 3 3
DOG 5 5 5
MICE 1 1 1
I need it to dynamically output based off COL1, the output should look like this. When there are more rows for CAT, it should output more columns. Kind of like merging the columns
COL1 AAA BBB CCC AAA BBB CCC AAA BBB CCC
CAT 1 3 3 1 2 2 1 4 4
DOG 2 3 3 5 5 5 NULL NULL NULL
MICE 1 1 1 NULL NULL NULL NULL NULL NULL
This is my table.
CREATE TABLE tpivot
([col1] varchar(80), [col2] varchar(80), [col3] varchar(80), [col4] varchar(80), [col5] varchar(80)) ;
INSERT INTO tpivot
([col1], [col2], [col3], [col4], [col5])
VALUES
[code]...
My goal is to turn the table so that the output look like this.
col1 col2 col3 col4 col5
Datum 01.12.2014 02.12.2014 03.12.2014 04.12.2014
EC -204.9 -352.9 -105 -371
Mastercard -88 0 -182 -112.9
Postfinance 0 -79.9 0 -751
VISA -19 -20 -436 -346
I need to have a dynamic pivot since i import the table from a csv that could have different amount of columns each time. I can't even get a static pivot to work.
The dynamic SQL statements with output parameters, unfortunately, in the documentation are not described.
À) Simple example of the dynamic SQL statement with output parameters
-- dynamic SQL statements expects parameter of type 'ntext/nchar/nvarchar'.
declare @SQLString nvarchar(4000), @ParmDefinition nvarchar(4000)
-- the third parameter passed in the dynamic statement as by output, returns the length of
-- the hypotenuses of a right triangle, two first parameters are lengths of legs of a triangle
declare @nHypotenuse float
select @SQLString = 'select @nHypotenuse = sqrt(square(@nLeg1_of_a_triangle)+square(@nLeg2_of_a_triangle))',
@ParmDefinition = '@nLeg1_of_a_triangle float, @nLeg2_of_a_triangle float, @nHypotenuse float out'
-- we call the dynamic statement in such a way
exec sp_executesql @SQLString, @ParmDefinition, @nLeg1_of_a_triangle = 3.0, @nLeg2_of_a_triangle = 4.0, @nHypotenuse = @nHypotenuse out
-- or in such a way
exec sp_executesql @SQLString, @ParmDefinition, 3.0, 4.0, @nHypotenuse out
select @nHypotenuse -- Displays 5.0
B) Example of usage of the dynamic statement with output parameter and the function GETALLWORDS.
The following stored procedure get all words from a field of the type text or ntext, the word length should not exceed 4000 characters.

I have a STORED PROC for dynamic T-SQL that returns a OUTPUT varaible of typevarchar . This works fine in query analyzer.
But when I try to get values in asp.net page it does not return anything. No execeptions or errors also. Below is the code snippet
HDConn = CommonMethods.BuildConnection();SqlCommand cmd1 = new SqlCommand("GenerateRowids",HDConn);cmd1.CommandType = CommandType.StoredProcedure;// add parameters for Proccmd1.Parameters.Add("@TableName",SqlDbType.VarChar,50).Value= "MetricsMaster";cmd1.Parameters.Add("@ColumnName",SqlDbType.VarChar,50).Value= "MetricId";cmd1.Parameters.Add("@rowidval",SqlDbType.VarChar,30);cmd1.Parameters["@rowidval"].Direction = ParameterDirection.Output;try{cmd1.ExecuteNonQuery();//the below line does not print the valueResponse.Write(cmd1.Parameters["@rowidval"].Value.ToString());}My stored proc looks like :CREATE PROCEDURE dbo.GenerateRowids@TableName varchar(50),@ColumnName varchar(50),@rowidval varchar(30) outputASBegindeclare @sql nvarchar(4000), @Idval varchar(50)
set @sql = N'select left(MAX(' + @ColumnName +') ,1)+ convert(varchar(5),Cast(SUBSTRING((MAX(' +@ColumnName+ ')),2,(len(MAX(' +@ColumnName+ '))))as int)+1) from ' + @TableNameexec sp_executesql @query = @sql,@params = N'@rowidval varchar OUTPUT', @rowidval = @rowidval OUTPUT ENDGO
Is there any benefit to using Output parameters:eg.[query set-up and execution goes here]

Hello,
What I'm trying to do is get an XML query from a database and use the XML to render an excel document. Can this be done using SSIS? Can I actually read a column from a database and store it in a variable and then create an excel spreadsheet with that variable in SSIS? Would this be done in the control flow using the XML task editor?
Thanks,
Phil
Hi,
I've been looking into using the ability to select the table of an OLEDB destination task based on a package variable but would like to know if this could be utilised in the following example.
I have a CSV file (potentially there are many) with a number of rows. The rows do not necessarily contain the same number of elements. Each row has an EventID and this is used to determine the database table that the row is to be inserted in.
Initially i thought about using a conditional split to send each row down the path relating to its event ID. There would be multiple destinations depending on the table. With the possibility of 60 to 70 different event ID's this is very quickly going to get out of hand in the designer. I'd like to know if it would be possible to set up a case statement (or similar) in a script component and specify the table name as a variable depending on the event ID. I'd then use this table variable to set the destination task's table property.
Does this sound like a possibility or do i have to go down the route of multiple paths?
Many thanks in advance,
Grant

Preferrably the query should also be passed as a parameter to the stored procedure...If not,it should be constructed in the SP and a Part of the where clause is dependant on the value of another variable passed to the SP.
How should the query be constructed, executed, and then the Count(*) value returned?
"WHERE <condition1> AND <condition 2> ;
"AND <condition 2> " may exist or may not exist in the query; it is dependant."
In the old DTS package, we can use Active-x script to set the variable value:
DTSGlobalVariables("MessageData").Value = "This is a test"
How do we do the same thing on the SSIS?
I am under the "control Flow" tab.
Thanks.

I have to download a file via FTP from one of our vendors, the filename is MMDDYYYY.zip, this is a weekly file and is posted between Tuesday and Thursday, so basically I never know exactly what the file is going to be called, to fix that, I added a FTP Task that will download a file if the date = today (Today = Thursday, when the job kicks off), if this fails, try a file where the name = today-1 (Wednesday), if this fails, try today-2 (Tuesday), all of that inside of a Sequence Container and with MaximumErrorCount set to 3. This is fine and it works fine, good.
Now my other issue, the .txt file inside the zip file (1080.txt), after being decompressed, needs to be renamed to MMDDYYYY.txt, where MMDDYYY = to the file I downloaded, but I never know what the file is going to named (MMDDYYYY, MMDD-1YYYY, MMDD-2YYYY).
Is it possible to output the filename of the file that I successfully download to a variable, so I can re-use name?
Any other thoughts?

Hi there,
I am working on SSIS package that gets data from SQL 2005 Database and writes that to a flat file. But I need to write the count of records as part of the header.
Here is what i am trying:
The OLE DB Source is calling a stored procedure and returning two things i.e. a resultset and an output parameter. The data access mode is SQL Command.
Code SnippetEXEC [Get_logins] ?, ?, ? OUTPUT
In the Set Query Parameters dialogbox, all the three patameters are mapped to three different user variables.
What is happening is that the user variable that is mapped to output parameter is never updated. The header property expression is written as follows
Code SnippetRIGHT("0000000000" + (DT_STR, 10, 1252)@LoginCount, 10)
I tried to watch the variable in watch window but to no avail. Any guidance if it is bug or I am missing some thing? Any thoughts, how can I accomplish this? I have also tried adding Row Count Transformation but its variable has the same behaviour. If I set the value of @LoginCount variable to some value, this initially set value is successfully written to the file header.
Thanks

Really stuck trying different ways to get a string variable (expression based) to parse and run correctly in an ExecuteSQL task. Would someone be able to advise why one of the following methods works and the other does not?
I'd really prefer to have the second currently not working method be used if possible.
WORKS:
"[audit].[up_LogEtlPackageStart]
@ETLAuditParentKey = ?,
@Description = ?,
@PackageName = ?,
@PackageGuid = ?,
@PackageVersionMajor = ?,
@PackageVersionMinor = ?,
@PackageVersionBuild = ?,
@MachineName = ?,
@ExecutionGuid = ?,
@LogicalDate = ?,
@StartTime = ?,
@Operator = ?,
@ETLAuditKey = ? OUTPUT"
FAILS:
When the variable expression is set as follows I :
Code Block
"[audit].[up_LogEtlPackageStart]
@ETLAuditParentKey = " + (DT_WSTR, 100)@[User::ETLAuditParentKey] + ",
@Description = " + (LEN( @[User::PackageDescription]) == 0 ? "' '" : @[User::PackageDescription]) + ",
@PackageName = " + @[System::PackageName] + ",
@PackageGuid = " + @[System::PackageID] + ",
@PackageVersionMajor = " + (DT_WSTR, 100)@[System::VersionMajor] + ",
@PackageVersionMinor = " + (DT_WSTR, 100)@[System::VersionMinor] + ",
@PackageVersionBuild = " + (DT_WSTR, 100)@[System::VersionBuild] + ",
@MachineName = " + @[System::MachineName] + ",
@ExecutionGuid = " + @[System::ExecutionInstanceGUID] + ",
@LogicalDate = " + (DT_WSTR, 100)@[User::LogicalDate] + ",
@StartTime = " + (DT_WSTR, 100)@[System::StartTime] + ",
@Operator = " + @[System::UserName] + ",
@ETLAuditKey = " + (DT_WSTR, 100)@[User::ETLAuditKey] + " OUTPUT"
This method generates a "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"
Any ways to get the second failing expression to work?
Is this a problem due to the OUTPUT parameter?
THANKS!
Hi guys, I have the following store procedure:PROCEDURE dbo.AddSearchColumn (@A1, @A2. @A3, @A4, @A5) ASDeclare @cElements cursor,@DocNum varchar(100)BEGIN Set @cElements = cursor for select FirstNaname rom dbo.DocTable1open @cElements fetch NEXT from @cElements into @DocNumwhile (@@FETCH_STATUS = 0) begin if (@DocNum==@A1 //Here is what I need to do: I want use @A1 at the first loop step, @A2 at the second, and so on....... // @A1, @A2 are the parameters in inputendENDclose @cElementsDEALLOCATE @cElements I hope my explanation is clear.Please, give some hints.Thanks for your time,Christian Malatesti
View 7 Replies View RelatedOk, I have a table with several column all labeled, column1, column2, etc. I need to loop through them so I have this statement which will loop through and get the first value, then go to colun2, etc
declare @score int
declare @stm nchar(500)
set @score=0
While @score<=50
Begin
Set @score=@score+1
set @stm='select column' + rtrim(convert(char(2),@score))+' from tablename'
exec sp_executesql @stm
if @score>50
Break
else
COntinue
end
My question is, how can I stuff this value from the dynamic sql into a variable such as:
set @newvalue='exec sp_executesql @stm '
Thanks,

Hi guys
I have a trigger which retrieves database names from a table.
I need to use this retrieved database name in another sql insert statement as a variable
e.g. set @mydbname = Select .... from.. (to get the database name)
then..
insert into @mydbname.dbo.emplTable
At the moment it reads @mydbname as the string "@mydbname" not the value the variable holds
I need the database name as a variable because i have to write to the correct database (there are 15)
Any help appreciated

Hi,
how to use a Dynamic variable on a function, to explan my self more here is a sample, we use this on SP but the function not allow executing.
DECLARE @SQL nvarchar(1000);set @sql=''
DECLARE @RESULT nVARCHAR(1000);SET @RESULT=''
DECLARE @mpq int;SET @mpq=0
DECLARE @FILENAME VARCHAR(40);SET @FILENAME='parm'
SELECT @RESULT =SCHEMA_NAME((SELECT SCHEMA_ID FROM SYS.TABLES WHERE NAME=@FILENAME))+'.'
SET @SQL=N'SELECT @mpq = CASE WHEN MPQ=1 THEN 10 WHEN MPQ=2 THEN 100 WHEN MPQ=3 THEN 1000 END FROM '+@RESULT+'PARM'
EXEC SP_EXECUTESQL @SQL,N'@mpq INT OUTPUT',@mpq OUTPUT
Here's the WRONG way to do what I want. I need a way to populate a variable from the output of a dynamic query.
declare @TableName sysname
set @TableName = 'Customers'
delcare @Output bigint
declare @SQL varchar(max)
set @SQL = 'select top 1 RowID from ' + @TableName
select @Output =
EXEC (@SQL)
create function udf_GetDatabaseFingerPrint(
@DBID bigint
)
begin
returns bigint
as
declare @dbname sysname
, @iBig bigint
, @tSQL varchar(2000)
select @dbName = Name from Master.Dbo.Sysdatabases where DBID = @DBID
set @tSQL = 'select sum(Rows) from ' + @dbName + '.dbo.sysindexes'
set @iBig = exec(@tSQL)
return @iBig
end
Hi,
I've a roblem with table variables in dynamic sql context.
If i use it with normal sql there is of course no problem.
Simplified it looks like this:
-- Standard SQL ----------------------------------------------------------------------------------------------------------------
DECLARE @TestTable as TABLE(MyBigInt bigint NOT NULL, Myint int NOT NULL);
INSERT @TestTable SELECT 4711,10
SELECT* FROM @TestTable
-----------------------------------------------------------------------------------------------------------------------------------------
If i do the same thing in dynamic sql, i get errors.
-- Dynamic SQL ----------------------------------------------------------------------------------------------------------------
DECLARE @DynamicTestTable as Table(MyBigInt bigint NOT NULL, Myint int NOT NULL);
DECLARE @SQLString as nvarchar(max), @Parameters as nvarchar(2000);
SET @Parameters = N'@DynamicTestTableOUT as Table(MyBigInt bigint NOT NULL, Myint int NOT NULL) OUTPUT';
SET @SQLString= N'INSERT @DynamicTestTableOUT SELECT 4711,10';
EXECUTE sp_executesql @SQLString, @Parameters, @DynamicTestTableOUT = @DynamicTestTable OUTPUT ;
SELECT* FROM @DynamicTestTable;
-----------------------------------------------------------------------------------------------------------------------------------------
What is wrong with tis code? Or are table variables not supported inside dynamic SQL?
Thanks in advance

I'm calling a procedure on a remote Server (local SQL2005, remote SQL2005) and I need the return value.
Local:
declare @value int execute ('exec mbtest1.dbo.psybcis ?', @value OUTPUT) at [REMOTESQLSERVER] select @value
Remote:
create procedure [dbo].[psybcis] (@value int OUTPUT) as begin select @value = '13' end
I do not get a value in the OUTPUT variable - just NULL. Documentation says:
Execute a pass-through command against a linked server
{ EXEC | EXECUTE } ( { @string_variable | [ N ] 'command_string [ ? ] ' } [ + ...n ] [ { , { value | @variable [ OUTPUT ] } } [ ...n ] ] ) [ AS { LOGIN | USER } = ' name ' ] [ AT linked_server_name ] [;]
There is an OUTPUT parameter, but how does it work? Is my syntax wrong?
It works when using following syntax,
declare @value int exec [REMOTESQLSERVER].mbtest1.dbo.psybcis @value OUTPUT select @value
but I need to use this procedure call in a distributed transaction to a Sybase ASE server and this syntax is not allowed for cross-system-calls.
So first I want to get it work from SQL2005 to SQL2005.
I'm trying to call a stored procedure in an Execute SQL task which has several parameters. Four of the parameters are input from package variables. A fifth parameter is an output parameter and its result needs to be saved to a package variable.
Here is the entirety of the SQL in the SQLStatement property:
EXEC log_ItemAdd @Destination = 'isMedicalClaim', @ImportJobId = ?, @Started = NULL, @Status = 1, @FileType = ?, @FileName = ?, @FilePath = ?, @Description = NULL, @ItemId = ? OUTPUT;
I have also tried it like this:
EXEC log_ItemAdd 'isMedicalClaim', ?, NULL, 1, ?, ?, ?, NULL, ? OUTPUT;
Here are my Parameter Mappings:
Variable Name Direction Data Type Parameter Name
User::ImportJobId Input LONG 0
User::FileType Input LONG 1
User::FileName Input LONG 2
User::FilePath Input LONG 3
User::ImportId Output LONG 4
When this task is run, I get the following error:
0xC002F210 at [Task Name], Execute SQL Task: Executing the query "EXEC log_ItemAdd @Destination = 'isMedicalClaim', @ImportJobId = ?, @Started = NULL, @Status = 1, @FileType = ?, @FileName = ?, @FilePath = ?, @Description = NULL, @ItemId = ? OUTPUT" failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_I4)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The User::ImportId package variable is scoped to the package and I've given it data types from Byte through Int64. It always fails with the same error. I've also tried adjusting the Data Type on the Parameter Mapping, but nothing seems to work.
Any thoughts on what I might be doing wrong?
Thanks.
