Can Anyone Explain What The Pre-execute Phase Is Doing For OLE DB Data Sources Using Sql Commands?
Nov 3, 2006
I have a project which spans multiple servers and aggregates literally billions of rows of data into a much smaller and manageable result set which I store on another server. There are two stored procedures which take up 99.9% of the processing time. Each one of these SPs are estimated to run over 3 hours a piece (gives you an indication of how much data there really is). With in this SSIS package, I have two control flows, one for each SP. When I run the SSIS package from VS2005, I can see that there is a pre-execute phase which takes about an hour abnd a half to complete, and then move on to executing. My question is, what the heck is this, and what is it doing? I know it validates the sql in the procedure, but does it actually run the SP during that pre-execute phase? If it does, is there any way to get around that?
Any help would be appreciated.

What happens during the pre-execute phase?
Is there anything I can do to optimize it's execution?
I have a package that takes data from 2 SQL Server sources, unions them, and writes to a sql table.
The pre-execute takes 20 minutes, and the execution takes 45 seconds.
Thanks

Does anyone know why SSIS sometimes just sits in the Pre-Execute phase of a data flow and does nothing? It doesn't matter how elaborate the data flow is or the volume of data. It can sometimes take 80% of the task's run time.

Hi,
I have a SSIS package which pumps data from one server to other without any additional steps. There are 11 tables for which data is transferred. And this packages runs fine on two different environments but fails in one environment i.e. on SIT.
It doesn't throw any error and every time stops at the below step
[DTS.Pipeline] Information: Pre-Execute phase is beginning.
Progress: Pre-Execute - 0 percent complete
Progress: Pre-Execute - 1 percent complete
Progress: Pre-Execute - 2 percent complete
Progress: Pre-Execute - 3 percent complete
Progress: Pre-Execute - 4 percent complete
Progress: Pre-Execute - 5 percent complete
Progress: Pre-Execute - 6 percent complete
Progress: Pre-Execute - 7 percent complete
It doesn't complete neither throws an error. Any pointers on what the problem could be
Thanks

Hi all,
I have a monster SQL query (SQL Server connection) that I'm trying to export to flat file. My package appears to just stick on the "Pre-Execute phase is beginning" stage. (I left it running overnight, and it's still going... no error message, I think it's just hung. If I include a "Top 10" in the my source query it completes without a problem. I'm wondering if it's an out-of-memory issue, but when I've run into this in the past there have been error messages generated. I've tried using both a Data Reader and an OLEDB Datasource. Does anyone have any ideas of what's going on and how I might fix it?
Thanks!!!Jess

Any help or clues as to why this is happening on my server is greatly appreciated.

Hi,
I wanted to know if there is a way to execute sql commands on the operating system's command line. If it is possible, then how do we do it ? For example to execute a SELECT * from Table statement what are we supposed to do ?
Thanks

Ive got a List<sqlCommand> and I want to execute all the commands in it, but only using one trip to the database. I dont need any return values from any of these commands. Most of the commands are update/insert/delete. Sometimes after a insert command there may be a command "set @NEWID =identity_insert" to facilitate the next insert to a related table, but thats the only other type of command to insert/update/delete.I am using microsofts enterprise data application block. I want to execute all the commands in the list with just one trip to the database. Would the following code achieve this : db = DatabaseFactory.CreateDatabase("wlmAdmin"); foreach (SqlCommand sc in saveCommands) { db.ExecuteNonQuery(sc); }or would this make multiple trips to the database? Im not 100% on whats going on behind the db object. If I create the db Item in the constructor of my class using "db = DatabaseFactory.CreateDatabase("wlmAdmin");" would this mean that every instance of that class would maintain an open database connection throughout its scope/lifetime?Ive created the class to retrieve all data using a single stored procedure and then when saving, the class builds a List of SqlCommands which as Ive mentioned I want to execute in one trip, to make the number of trips to the database as small as possible. Because of this I don't need the db object maintain an open connection to the database all the time. However It doesnt seem to have any dispose methods so Im not clear on how it operates.In the case that the code above opens a connection for each command, how would I got about batch executing the queries in one trip?Thanks,C

Hello,
I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".
To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.
The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).
I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.
Why the process could be so long during this phase?
There is a way to optimised my package to avoid that?
Any idea is welcome.
Thanks.
Guillaume

I'm building a simple webform, except Visual Studio and my service provider have combined to drive me nutty.
First, I MUST use an ODBC connection to my remote SQL Server do to some unknown configuartion problem. I've been playing with Visual Studio for only a month, so normally when something goes wrong I can go look in the mirror and find the culprit. This is different. I've got a totally functional web form with a SQL Connection, but when I try to change it to an ODBC Connection, I get the following error.
An OdbcParameter with ParameterName '@CertHolder' is not contained by this OdbcParameterCollection
My coding is fine because I stole it straight from the walkthrough and it works. But the specifications that Visual Studio provide are quite suspect. Please note the failure to include some key "@" signs.

I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios:
Some of the records in the external data source may not exist in SQL.Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server.Some of the records in the external data source may be the same in SQL.
Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 above). In fact case 2 is the most critical.
I thought of making a query with a left outer join between the data in the external data source table (SOURCE) and the data in the SQL Server table (DESTIN). The join is done on the respective primary keys (composed keys of up to 10 columns) and one of the WHERE conditions will be that the value in SOURCE is different from the value in DESTIN.
The result of this query would be exactly what I need to import.
How to do this in SSIS??? I couldn't figure out how to join tables in different data sources yet.
In fact I cannot write a stored procedure to do that, since one of the sources is in a datasources not SQL Server.
I have seen the Lookup transformation in this article http://www.sqlis.com/default.aspx?311 but this is not exacltly what I want to do.
Another possibility is to use the merge join, but due to the sorting I believe its performances would be terrible!
Thanks in advance for your suggestions!

Hi,
I am pretty new to SSIS. I am trying to create a package which can accept data in any of several formats. i.e. CSV, Excel, a SQL Server database/table and import the data into my destination database.
So far i've managed to get this working OK. However I am now TOTALLY stuck. I'm currently trying to just concentrate on the data sources being a CSV (using a Flat File Data Source) and/or an Excel Spreadsheet.
I can get the data in and to my destination using a UNION ALL component and mapping the data sources to it so long as both the CSV file and the Excel spreadsheet exist.
My problem is that I need my package to handle the possibility that only the CSV file might exist and there is no Excel spreadsheet. In which case i'd like the package to ignore the Excel datasource completely. Currently either of my data sources do not exist I get errors and the package terminates.
Is there any way in SSIS that I can check all my data sources to see which ones exist (i.e. are valid). If they exist I want to use them. If it doesn't exist i'd like to disgard it (without error - as long as there is a single datasource the package should run)
I've tried using the AcquireConnection method in a script task on each of my connections, hoping that it would error if the file/datasource did not exist. It doesn't though (in the case of an Excel datasource it just creates a empty excel file for me).
The only other option I can come up with are to have seperate packages depending on the type of data we want to import and then run a particular package depending on the format of the source data. This seems a bit long winded. I am pretty sure I must be able to do what I want to achieve but I can't work out how.
I'll be grateful to anyone who can send me any tips/hints/links on how I can achieve this.
Many thanks

Hi, i'm wondering which is the best way to search data in a SQL Server.
I reach data using Data Sources and Data Views and also with OLE DB Source with a Data access mode: Named query.
I have to write the data into a Flat File. So, does any one knows which is the best practice for this? Or any one of the two are good choices?
Thanks for your help.

Hi,
In my project i want a report. In that report data is getting from more than one data sources(systems). While creating data source view i used named query for both primary and secondary data source. But at the time of crating "Report Model" i am getting below error.
An error occurred while executing a command.
Message: Invalid object name 'Table2'.
Command:
SELECT COUNT(*) FROM (SELECT SerialNum, ModelNum AS com_model

Is there any way to create a report with multiple data sources?

Hi all :)
I'm wondering if SSIS will be the solution to the problem I'm working on.
Some of our customers give us an Excel sheet with data they want to insert or update in the database.
I've created a package that will take an Excel sheet, do some data conversion so the data types match up and after that I use a Slowly Changing Data component to create the insert/update commands.
This works great. If a customer adds a new row to the Excel sheet or updates an existing row changes are nicely reflected in the database.
But now I€™ve got the following problem. The column names and the order of the columns in the Excel sheet are not standard and in the future it could happen a customer doesn't even use an Excel sheet but something totally different.
Can I use SSIS for this? Is it possible to let the user set the mappings trough some sort of user interface? I€™ve looked at programmatically creating the package but I€™ve got to say that€™s quit hard to do€¦ It would be easier to write the whole thing myself than to create the package trough code ;)
If not I thought about transforming the data in code before I pass it on to the SSIS package in something like XML. That way I can use standard column names and data types.
So how should I solve this problem? Use SSIS or not?
Thnx :)

Hi i have data on a Server in a different database which i like to access from within my ssis job.
I just need to look up information from one table on this database so i can references it. Is there a way of doing this is SSIS. Rather then me having to load the data from one database to another as the data may change.
i tried having 2 sources of data feed into a look up but that does not work..

Hi there,
On my home page I have several different folders to reports which require different data sources. the problem is that within these folders there are multiple copies of the same datasource. is it possible to store all of the datasources in one folder, one location? it would certainly be easier when changes to usernames and passwords need to be modified!
Thanks,
Rhonda

I searched and read about Data Sources and I'm seeing that there is no advantage in using it, which is what I found from playing around with it.
I expected that you would set a global connection in Data Sources and somehow link this to the things in your Connection Manager, giving you one place to switch from one environment to another. But reading the discussions here and playing around with it, this is not the case.
So, why is it there?
Next question.... another thing I gathered so far is something called "Configurations" that will do what I was describing above. Where do I do this?

I'm trying to combine two reports I've created into a form letter. The goal is to have a letter that indicates the students maximum UBSCT score for Math, Reading and Writing. Also in the letter we want to include the student's total number of credits awarded and overall GPA. I not sure if I need to try and combined the two queries or use two different data sources in Reporting Services. I've tried creating one sql statement but the grouping are giving me fits. I fairly new to Reporting Services.

I have an OLAP server and would like to use my Chart FX software without having to purchase the OLAP extensions on the server due to budget restraints (ouch).
I've heard that it is possible (although limited) to attach toan OLAP cube using SQL select statements (not MDX).
Basically, I would like to pull the OLAP data in the relational sense.
Is this possible? If so, are any good articles on this subject?
I'm new to OLAP and would like to transition slowly.
Thanks in advance :)

Hi guys,
I manage to get the SSIS working. Now I would need to do these tasks.
I first want to get data from 2 different sql servers. What would be the best method to accomplish this? Both are in Sql Server 2005.
Secondly I want to make sure if any of the servers couldn't be found on the network or in any case the getting data task failed for any one of them the package won't continue and an email should be send to an email address.
Thirdly If everything is ok then I should combine both and generate one sequence no for them and save them on to another location and then generate a file with modified values.
Can anyone help me regarding these tasks?
Thank you
Gemma

In brief, here is my quandary… I have a GridView on a page with some radio buttons, a couple of check boxes, some drop downs etc. And depending on what the user selects the Grid View needs to show different columns from the database…
The easiest way I have found to do this is to have a separate Data Object for each “view�, i.e. each variation of the checkboxes and radio buttons (which determine which dropdowns to use for the variables) and then bind the GridView to the specific Data Source at runtime…
It seemed like a good idea at the time, but now I have over 7 different data connections cluttering up the design view, and more to come and I feel like I am missing a better way to achieve the same results…
Does anyone have some advice for a major novice?
Here’s the beginning of a large set of nested ifs, if this is the way it’s done that’s fine too, I’ll just keep creating data sources, I just get the feeling there must be an easier way to do this..
protected void Button1_Click1(object sender, EventArgs e)
{
if (RadioButtonList1.SelectedValue == "Vendor") {
if (CheckBox1.Checked == true) {
GridView2.DataSourceID = "ObjectDataSource4";
GridView2.DataBind();
TextBox1.Text = "Search";
} else {
GridView2.DataSourceID = "ObjectDataSource1";
GridView2.DataBind();
TextBox1.Text = "Search";
}
} else if (RadioButtonList1.SelectedValue == "Store Number")
{ GridView2.DataSourceID = "ObjectDataSource2";
GridView2.DataBind();}
else {
GridView2.DataSourceID = "ObjectDataSource3";
GridView2.DataBind();
TextBox1.Text = "Search";
}
}
Any advice for a major novice would be greatly appreciated! Thanks!

I'm just wondering if it is bad programming practice to have many data sources on one page. I need a "Matrix" type of page that grabs data from many tables and so far I have 5 data sources. Is this common or is there something I should be doing to make it more efficient?

Is it possible to create a recordset from two different datasources?
Such as
SELECT * FROM DataSource1.TableName WHERE ColumnName IN (SELECT Column FROM Datasource2.TableName)
Thanks.

Can I import in my query a file from other sources (in this case it's a job that has elaborated server database data, but I could be in the need of using for instance Excel files or others) and compare its fields with the tables in my query?
Thank you.

Not sure if this is possible, here is the scope:
I have a vb program that calls a sp. My vb program connects to DataSource1, Catalog1 and to DataSource2, Catalog2. My sp resides in Catalog1 using a table from catalog1 and a table from catalog2.
Is this possible to do?

If I were to change a data source that many packages use (say, from box "SQL-2" to "SQL-1"), would I have to re-upload the packages that used that data source? Or would the packages already on the server receive that change somehow?
(currently realizing that most of the packages use package-local data connections instead of project-wide data sources...)
Thanks!

I am attempting to pull in data from a flat file data source that contains dates in the following format "01012007 10:22" which translates to Month Day Year and Military Time. I want to turn this into a DateTime format so that I can insert it into the proper column. I have a SQL statement which will do this (see bellow), but I can't figgure out how to run the statement on the data before it reaches its destination.
Can anyone help?
The code is:
Code Block
cast(convert(varchar(16),(substring( REPORT_RUN_DATE,1,2 ) + '/' + substring( REPORT_RUN_DATE,3,2 ) + '/' + substring( REPORT_RUN_DATE,5,10 )),1) as datetime) AS REPORT_RUN_DATE

Hey all,
I'm coming from ASP and I used to have a global connection string accessible to all of my ASP pages that I'd use for all of my data access. This was really convenient because I could easily switch to a backup or local data source for testing/debug by changing the connection string in one place.
Now, I'm using ASP.NET with Web Matrix and I love the drag and drop functionality but its dropping my connection string all over the place. How can I do this and keep my connection string in one spot so I can have the same convenience of switching data sources.
Thanks in advance!
Larry
