Integer Variable Usage In SqlStatement Expression
Apr 27, 2007
I have an integer variable which i had to cast as a string in order for it to show as an integer in the sql expression which is a string in order for it to INSERT as an integer? Read that 5 times fast!!!
"INSERT INTO Table( SourceFileName, ProcessStartTime, ProcessEndTime, Processed, RowCountFlatFile, RowCountCleanInsert, RowCountDataConversionErrors, RowCountPKViolation, RowCountDuplicateInvoiceIDInSourceFile, RowCountISNULLCase1, RowCountISNULLCase2, RowCountConditionalSplit)
VALUES( '"+ @[User:aymentFileName] +"',
'"+ (DT_STR, 20, 1252)@[System:tartTime]+ "',
'"+ (DT_STR, 20, 1252)@[System:tartTime]+ "',
1,
"+(DT_STR, 4, 1252)@[User::rcSourceFile]+",
"+(DT_STR, 4, 1252)@[User::rcCleanInserts]+",
"+(DT_STR, 4, 1252)@[User::rcDataConversionErrors]+",
"+(DT_STR, 4, 1252)@[User::rcPKViolation]+",
"+(DT_STR, 4, 1252)@[User::rcExistingInvoiceID]+",
"+(DT_STR, 4, 1252)@[User::rcISNULLCase1] +",
"+(DT_STR, 4, 1252)@[User::rcISNULLCase2] +",
"+(DT_STR, 4, 1252)@[User::rcConditionalSplitErrors]+"
)"
all the variable beginning with rc are Int32 variables being loaded using the Row Count task. they are being inserted into an integer field in the table. Is this whack or what???
I was trying to cast is using DT_I4 but couldn't find any samples nor could I get it to work. The above is successful!!!

Can anyone tell me why this won't work, and what the right way is to do it:
<code>
DECLARE @DBNAME
SET @DBAME = 'TESTDB'
ALTER DATABASE @DBNAME...
</code>
It doesn't like me using the variable there, I get:
Msg 102, Level 15, State 1, Line 3
Incorrect syntax near '@dbname'.
Is there a way around this?

I have a stored procedure that uses containstable and want to make it a little dynamic so I was going to add a parameter that consist of the column names that needed to be search. But when I add a variable I get an error saying incorrect syntax....
Can you not use a variable as a column list?? I have a variable for search criteria and it works fine...
Here is my syntax
containstable([tablename],@columnlist,@srch)
I have been looking online and can't seem to find anything that says I can or cannot use a variable.

Looking for the way to convert a datetime field to only show the date (no time) in a gridview that is dynamically created by the statement.
string sqlStatement = "SELECT [column1], [column 2], [column 3]... FROM tbl WHERE ... I am trying to convert column 2 to the date without the time.

Hello,
I have a DateTime variable called CurrentDate that needs to reflect the current date, but the date portion only. I checked several functions in the Expression Builder to use with GETDATE() so that I could just get the date portion, but I didn't see anything that really fit. In a SQL query I would normally use CONVERT to do this.
Any ideas?
Thank you for your help!

What would be the correct syntax if I wanted to add the following lines into a variable using an expression? The lines should be the first two rows before my XML.

Hi all of you,
That's an easy one. I've got a Send Mail task which might send a message in plain text along with a SSIS variable.
Something like that:
'La tabla "' + SUBSTRING( @[System:ackageName], 3,20) + "' se ha cargado correctamente'
TIA for that,

Hi
I have some SSIS variables of type System.Object (they have to be this
type because they are used to hold the results of a single row result
set in an Execute SQL task which is querying an Oracle database.
Although I know the Oracle table columns are Numeric, this was the only
SSIS type that worked).
My problem is that I want to use these variables in expressions, but
can't - I get the error "The data type of variable "User::varObjectVar"
is not supported in an expression".
The only workaround I can think of is to use a script to assign
the numeric values (integers, in fact) that these variables hold to
other variables of type Int32.
Is that my only option, or am I missing something?
thanks

I have been successful using comments (to help remind me that the SQL is coming from a varaible which is set via an expresion) within the variable expression passed to a Source or Destination. I have been unable to get this to work in an ExecuteSQL control flow task when parameters are used within the query. I am not sure what is causing this not to work the fact that it is an ExecuteSQL control flow task or that the SQL has parameters (or perhaps that it also uses an OUTPUT parameter).
Any thoughts to share? Am I missing something?

I'm trying to do something very simple, and having a tough time with it.
I've got a Global Variable that gets a string value assigned to it in a Script Task, and then I need to access that value in Execute Process Task Expression. When running, by the time it gets to the Process Task, the global variable's value in the expression is still blank, even though a breakpoint on the task shows that it does have a value.
What am I doing wrong? This seems too simple to give me this much problem.

Greetings my SSIS friends
I am attempting to create an expression as follows:
"Select * from someTable where someColumn >= " + (dt_str, 25, 1252) @[User::DateTimeVariable]
The problem is that my variable is a Datetime field and when I convert it to string, the string will not execute correctly.
How to solve this problem?

First and foremost, I'm officially and thoroughly confused between Variable, Expression and settings. I need help clearify this up for me.
I'm going to use the Flat File Connection as an example.
I have:
> A global variable named: FileToImportFullPath (string) that stores the full path of the file I want to import. Note: the file path will change has the package executes (the location of the file depends on a number of conditions, namely the Date and Time of the package execution)
> A Flat File Connection Manager used by a Flat File source in the package's main Data Flow
So ideally, I want the Flat File Connection Manager's ConnectionString to be set to whatever the value of FileToImportFullPath variable is at the time. To accomplish this, I set the ConnectionString Expression to equal to FileToImportFullPath. First question, if I set the ConnectionString Expression, is it okay for me to leave the ConnectionString property (i.e. in the Editor or the Property Editor) blank? Second, whenever I leave the ConnectionString property blank, I will get a warning stating: "A valid file name must be selected". Since this is a warning, I ignored, but during exeuction, the value really is blank. Also, I'm 100% certain that the FileToImportFullPath variable is set correctly before the Data Flow step is executed.
All in all, I'm just confused if an object's property must be set if there is already an express for it (e.g., in the file move task, the source and the destination properties).
Thanks,
Jason

I have created a variable in a SQL Task and assigned it to a string variable. When I debug the container with a breakpoint, I can see the correct date value being assigned to the variable.
I have an ADO Net source setup to an Oracle connection. I need to pull the Oracle data down that has an updated date greater than the updated date in my ODS.
My issue is that the variable is not being passed through to my expression that I use for an ADO Net source.
"SELECT * FROM BI_EDW.GL_JE_HEADERS WHERE LAST_UPDATE_DATE > To_Date('" + (DT_WSTR, 19) @[User::varLastUpdateDate] + "','yyyy-mm-dd hh24:mi:ss')"

I have tried with this thing for hours and I can't get it to parse.
Trying to get last year so the expression should evaluate today as of "12/31/2014"
I looked all over on Google and couldn't find an expression to copy so I've been playing with it.
Here is what it is in SQL Server:
SELECT DATEADD(dd,-1,DATEADD(yy, DATEDIFF(yy,0,GETDATE()),0))
Absolutely could not get it to parse..even with DT tags, etc...

I'm using a file Task to rename files to include a Month and Year in the FIle. Part of the requirement in the file name is a two digit month. I have the following query built which will return a two digit month regardless if it's a one or two digit month.
SELECT REPLACE(STR(MONTH(DATEADD("Month", -1,GETDATE())), 2), ' ', '0')
This works perfect when running in T-SQL, but when attempting to define a variable in the expression
REPLACE(STR(MONTH(DATEADD("Month", -1,GETDATE())), 2), ' ', '0') expression keeps failing the evaluation?
Anyone run into a simliar issue or have a suggested work around?

Greetings once again SQL friends,
Sorry to bug you with my silly questions but this little problem has been driving me crazy for the last hour or so!
I am attempting to change the data type of a variable in an expression but I keep getting an error saying that the expression can not be evaluated.
The syntax I am using is as follows :
(dt_str) @[User::MAX_OFFER_PRICE_ID]
My variable MAX_OFFER_PRICE_ID is type int32 and I am attempting to cast it as a string.
What am I doing wrong?!
Thanks for your help in advance.

I have one package that executes 4 child packages (5 total). All 5 packages are set to log information using a connection string with a variable set at runtime for the location. The child packages use a parent variable to get the log connection string from the parent package.
The parent package logs fine, but a strange behavior occurs with the child packages.
The child packages all log data to the location used in the configuration file variable during runtime (like it's supposed to). However, I would get an error right before the first child package finishes execution saying path not found. Just for giggles, I created the folder I use in my development environment on the production environment. The error goes away, but the log file is created in that folder with no data in it. Subsequently, the log file with the data is created in the location set in the configuration file. Now I have two log files!!!!
Anybody know how to fix this?!

Hi
We have set up an SSIS package which goes to an FTP site and downloads files.
Everything is fine... EXCEPT (lol) when there are no files to download. This then fails the task.
However, I want the package to continue to run.
Is there away of assigning the error message given to an expression and then using the expression in the precedence contraint?
thanking you in advance
David

I have been using SSIS for a while now, originally in SQL 2008 but more lately SQL 2012.
I discovered the GETDATE() function in SSIS so I thought I would use this in a variable expression in a Master/Driver package with the child parameters mapped to this variable. A big mistake. The value is not persisted, it gets updated each time the variable is read, so it's back to setting the variable value using a script task in the Master/Driver package.

Working on a new database where the Date and Time are stored in a Date Time Field.
Then working on an OLDER database file within the same SQL Database contains these 2 items as integers:
transDate = "71615" (July 16, 2015)
transTime = "12345" (01:23:45 AM)
How do we convert both of them into a single SQL DateTime field such as "2015-07-16 01:23:45.000" so that it can be used in a join restricting to a date time in a different SQL File that properly has the DateTime in it?
This works well for converting the transDate Part in the select statement:
Β Β dbo.IntegerToDate(at.transDate) as transDate
Β Β * That returns: "2015-07-16 00:00:00.000"
* The resulting data must work directly in a Microsoft SQL Server Management Studio Query using either using the "on" statement or part of the "where" clause. In other words, NOT as a stored procedure!
Also must be able to be used as a date difference calculation when comparing the 2 files Within say + or - 5 seconds.

I have created a heat map and it is working pretty well. The only issue I am having is that the expression for the fill is using "DataSet1"
=Code.GetHeatmapColor(sum(Fields!AnnualPremium.Value),Min(Fields!AnnualPremium.Value,"DataSet1",Recursive),
Max(Fields!AnnualPremium.Value,"DataSet1",Recursive))
This is making the heatmap look at the whole dataset instead of just what I am grouping by. Within the Dataset there are Regions and Credit Unions. Since the Dataset is looking at an entire region, the heatmap is coloring based on all data for the region. I need to heatmap to color based on the Credit Unions in that region. The Credit Unions are a group. I need the group to be the value it is referencing in the heat map and not "DataSet1". I have been told to use scope or a variable but cannot get it to work correctly.

Has anyone encountered this before?
My colleague opens up an SSIS package with variables, many of which use expressions built with the Expression Builder. She cannot bring up the Expression Builder by clicking the ellipsis (...) in the "Expression" Property of the Property Window, regardless of whether "EvaluateAsExpression" is set to True or False.
I can open up this same package and use the Expression Builder just fine. Any ideas?
Apologies if this has been answered already, I did many searches to try to find the solution before posting here.
Thanks much!

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 = \test?, Folder = test? and JobNumber = 12345?. 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 Im 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 = \LiveServer?, Folder = Job? and JobNumber = 33091?.
After series of consequent executions I have got following log file:
¦ Execute Process Task 1¦ Executing the process \LiveServerJob_33091date.bat?
¦ Execute Process Task 2¦ Executing the process \Test est_12345 ime.bat?
¦ Execute Process Task 1¦ Executing the process \Test est_12345date.bat?
¦ Execute Process Task 2¦ Executing the process \LiveServerJob_33091 ime.bat?
¦ Execute Process Task 1¦ Executing the process \LiveServerJob_33091date.bat?
¦ Execute Process Task 2¦ Executing the process \Test est_12345 ime.bat?
¦ Execute Process Task 1¦ Executing the process \LiveServerJob_33091date.bat?
¦ Execute Process Task 2¦ Executing the process \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 default? 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) youll 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 cant 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.

Hi,
I have a data flow task within a foreach file loop. My problem occurs when I tried to make up an expression for the connection string of the Excel connection manager. Somehow I can see only system variables and none of the variables which I set up within the scope of the foreach file loop.
Can anyone provide me any insight into this mystery? As far as I can see, all the variables I created in the foreach file loop are still showing on the variable windows (without the Show All Variable button clicked).
Thank you very much and hope to hear from someone soon!

Hello,
I am having a hard time setting the executable path for an Execute Process Task in SSIS. I have a variable that is initialized at package statup which holds the path to an executable in Windows. When I set the property "Executable" Path in an expression, I get a warning that the path for the executable is not set. One workaround was to try and initialize the variable with a bogus path with the hopes that the "correct" value will be written on run-time. NO LUCK. I still get the error and I cannot run the package until I put a static path.
Does anyone have a clue as to what is going on??
