I'm attempting to create a new GUI for an existing MySQL database I have. I would like to program this application using Visual Studio 2005 using the Visual C++ or C# language.
I'm having trouble connecting to the database though. When I attempt to add it as a data source I get the following error: "Could not retrieve schema information for table or view"
I'm using the MySQL ODBC driver version 3.51 and MySQL versoin 5.0. Visual Studio 2005 Professional Edition.
Can someone help me get this project started? How do I connect to my database?
I 'm trying to get countNumber from a select statement in MySQL source. Something likes this:
select @countNumber = count(*) from tableName where condition_1 = xxx
I use ExecuteSQLTask to get the result set with result name @countNumber along with ADO.NET connection type. I 've installed mysql-connector-net-5.0.5 cause the source is MySQL 5x.
And I got a task failed error which is described below:
[Execute SQL Task] Error: An error occurred while assigning a value to variable "new_process": "Result binding by name "@new_process" is not supported for this connection type. ".
I am testing an application that uses mysql that works 100% fine with Microsoft Windows XP on Windows Vista Premium Home Edition.
Using Vista's ODBC Data Source Administrator I have set up and successfuly tested the DSN Connection to the Database.
However, when I call the set up DSN with the application I get [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
I am using the mysql-connector-odbc-3.51.12-win32.
I have tried editing the registry DSN files - the problem still persists.
I need to see inside a SSIS 2012 project a new SSIS installed component, but in the SSDT 2010 I cannot see the SSIS Data Flow Items tab for adding data source/data destination respect to the choose toolbox items pane.
I am working on mysql (linux). I cant add forign key to my tables. ALTER TABLE test ADD CONSTRAINT ldf_fk FOREIGN KEY(lead_code) REFERENCES source(lead_code)
I have a package that hangs in the designer after I change the sql statement in a DataReader Source from a 'select' to a 'call stored procedure'. The stored procedure takes 2 date parameters. I use an expression to build the 'call stored proc' statement and the 2 date strings. The data reader source uses an ADO.Net connection manager. The ADO.Net connection manager uses the provider for MySQL (Connector/.Net 5.1) which I installed from MySQL.com (http://dev.mysql.com/downloads/connector/net/5.1.html). Before creating the stored procedure I had been using an expression to build a 'select' statement with two date variables as follows:
The sql for the data reader source is set via the sql command property of the data flow component.
After testing the sql, I created a stored proc from this sql and then changed the expression (using the sql command property of the the data flow component) to build the 'call stored proc' statement, like this.
then when I tried to switch to the data flow tab, the editor froze, with the status bar saying "validating datareader source". The data flow tab says "Loading...". I don't know how to troubleshoot this. Each time I have tried I have had to kill the application. Any ideas/suggestions?
Two connections ==> one is using OLEDB connecting to SQL server 2005 and the other using ADO.NET's ODBC option to connect to mysql;
Two "Execute SQL Task" ==> one gets maximum ID(bigint) from a SQL server table and the other gets the maximum ID(unsigned) from a mysql's table and bind them to two variables ID1(string) and ID2 (int 64). http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1902297&SiteID=17&mode=1 ;
And one DataFlow whose data source is DataReader Source which queries mysql "select * from table where ID > cast(@ID1 as signed) and ID <= cast(@ID2 as signed) ". To debug, I put a DataViewer between Data Flow Source and Data Flow Destination.
Run the package, I found no data coming into DataViewer and no error message as well. However if I remove the "<=" sign and change the DataReader Source query to "select * from table where ID > cast(@ID1 as signed)", It works perfectly. Initially I thought it's variable @ID2's issue. But if I replace "<=" sign with ">=" sign in the query ==> "select * from table where ID >= (cast(@ID2 as signed) -100)", there is no problem. After tried many times, I found that query just doesn't work with "<" sign or "between". Plus the result of running package tells it's successful but just no records got inserted into Data Flow Destination.
I was wondering if it was possible to add an identity column to a flat file data source as it is being processed in a data flow. I need to know the record number of each row in the file. Can this be done with the derived column task or is it possible to return the value of row count on each row of the data?
, Hi In this code how can I create a new data source and new data source view and model and structure that it run dynamic. In this code I have a lot of errors, that they are about server and database don€™t have in current code, In this code, first I should definition server or no?
How can I create data source and data source view and model and structure? Please say code of that, and guide me. databasename and srv is unknown. Do I add other reference with analysis services? Please explain about these codes: ************************************************************************ 1) RelationalDataSource dsNew = new RelationalDataSource( datasourceName, Utils.GetSyntacticallyValidID( datasourceName, typeof(RelationalDataSource)));
I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
What is the best way to deal with a flat file source when you need to add a new column? This happens constantly in our Data Warehouse, another field gets added to one of the files to be imported, as users want more data items. When I originally set the file up in Connection Managers, I used Suggest File Types, and then many adjustments made to data types and lengths on the Advanced Tab because Suggest File Types goofs a lot even if you say to use 1000 rows. I have been using the Advanced Tab revisions to minimize the Derived Column entries. The file is importing nightly. Now I have new fields added to this file, and when I open the Connection Manager for the file, it does not recognize the new columns in the file unless I click Reset Fields. If I click Reset Fields, it wipes out all the Advanced Tab revisions! If I don't click Reset Fields, it doesn't seem to recognize that the new fields are in the file?
Is it a waste of time to make Advanced Tab type and length changes? Is it a better strategy to just use Suggest Types, and not change anything, and take whatever you get and set up more Derived Column entries? How did the designers intend for file changes to be handled?
Or is there an easy way to add new fields to this import that I am overlooking? I am finding it MUCH more laborious to set up or to modify a file load in SSIS than in DTS. In DTS, I just Edit the transformation, and add the field to the Source and Destination lists, and I'm good to go. My boss isn't understanding why a "better" version is taking so much more work!
Hi all, I saw a couple of other posts here on this topic, but none quite got to my issue. I'm trying to add error output to a custom source component (not a script, a custom component). The samples all seem to deal with transform components, and my issues seem to be unique to source components.
I have the following code related to error handling ...
Public Overloads Overrides Sub ProvideComponentProperties()
...
Dim output As IDTSOutput90 = ComponentMetaData.OutputCollection.New
Dim errorOutput As IDTSOutput90 = ComponentMetaData.OutputCollection(ERRORCOLUMNNAME)
Dim errorColumn As IDTSOutputColumn90 = errorOutput.OutputColumnCollection.New
errorColumn.Name = outColumn.Name
errorColumn.SetDataTypeProperties(DataType.DT_I4, 0, 0, 0, 0) ... End Sub
The confusions I have are: a) the stock advanced properties editor (I haven't provided a custom one) doesn't seem to "realize" that I have an error output, so provides no method to configure. I am believing it would need to know which Output columns can have their error/truncation redirected. I'd have thought setting ErrorRowDisposition on my output column would have been enough to trigger this ?? b) since I don't have any means of configuring, not surprisingly, when I try to connect my error output, designer complains that, "Ths error output cannot receive any error rows. This occurs for several reasons: Input columns or output columns are not yet defined. Error handling is not supported by the component. Error handling is not configured for the component." c) UsesDispoistions would seem to be appropriate only for a transform component
Thanks for reading, and appreciate any help or pointers. Bill
hi everybody, i want to create data source and data source view for data mining, with using C Sharp. i have create data source and data source view and export to XML file, but when i change to another computer, run those XML file, it return error, when i run statement to create and biuld mining model, what can i change on xml or how to run XML on another computer sucessfully, and have i build data source and data source view, how to do it.?
Today I was making a few reports. When I tested the reports in Visual Studio, they worked great: I got the expected result. But when I deployed the reports to our reportserver the problem started. When I click on the directory in which my reports are deployed, I got my 4 reports. Till now everything worked correct. But when I click on a report to view the results it went wrong. I got an error: "Cannot create a connection to data source 'Live'" (Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work. I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works. The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server. Maybe that is the problem?
I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?
Has anyone successfully used cherry's oledb provider for MYSQL to create a linked server from MS SQLserver 2005 to a Linux red hat platform running MYSQL.

I am looking for a way to migrate my data from a MySQL database to a SQL2005 Express data base. All of my MySQL Schemas only have 1 or 2 tables in them so I would imagine that it isn't that hard to do. I treid just exporting it to a CSV file with the intention of just using import/export in MSSQL but in the express edition, it ain't there. Like I stated all of my schemas are only 1 or two tables none are linked in any way they are independant table and the most records any one of the tables contain is around 250. Any suggestions?
Hi All, We will replace our website which currently build in php and mysql into .net and sql server 2005. What is the best way to migrate all the user account from current database in mysql into sql server, also considering that there is different database table and fields? Thanks in advance.
If this has been discussed before i apologise as i am fairly new to the asp forum and was not sure where to search for threads. I am upgrading to a new web plan that supports asp and i noticed that godaddy supports all of the above databases. I was curious if there are any advantages to using one db over the others as far as web is concerned? What i am looking to do is handle guestbook, logins for registered users which would control access to certain downloads and possibly pages as well. And it was also advised that i look into using a database to store and display dynamic information in my master page to only show the updated information instead of a complete new page each time. This would save on having to manage so many pages. So i would really appreciate any advice on the databases as i will be making my decision to go with a specific web host based on this. I would also appreciate any advice on a good web host for asp and database support. Thank you Jeff
problem is I don't have unfettered access to the MS SQL Server(7), so I need to send instructions on how to do it to a client.
After reading up a little, I figured "select view into ##tmp_table", and then dump the table, which, if I'm right, means I'll have an SQL dump that I can quite easily import into MySQL.
Problem,: What's the syntax to dump that temp table, or is there a better way to import the data into MySQL
I'm trying to import data from mySQL database to SQL server 2005. I installed mySQL odbc driver (3.51) and configured system DSN. However when I start SQL server import/export wizard mysql is not an option in data source dropdown. What do I miss?
Hi everyone, here is my situation and what I am hoping to accomplish. I want some data from my msSQL to be seen on my website but I do not want a website to access the msSQL database due to performance etc (the database is not intended for website use). Innitially I was thinking of exporting the data every 24hours to a text file that the website would access, but now I am thinking it would be better to have some data sent to a mySQL database that I have from my webhost.
I am not really sure what the best way to do this is, any help please? thank a lot
I'm trying to use linked server to import big amount of data(around 9 million rows) from mysql to a sql 2005 table.
I plan to create a stored procedure and use job agent to run it at off-peak time everyday. The SP is like:
.....
Truncate table sqltblA;
Insert Into sqltblA(col1, col2, col3) Select col1, col2, col3 From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB')
.....
But when I tried to CREATE the above SP from management studio, seems the sql server was trying to get all data from table mytblB and ended up with failure after several minutes hang. The error message is sth. like "running out memeory". BTW, during that several minutes hang, I can't query mytblB using mysql's tool as well. it seems to me that table got locked.
However if i try to change the returned result to 100,000 rows by changing script to
Insert Into sqltblA(col1, col2, col3) Select col1, col2, col3 From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB Limit 100000')
The SP could be created without any problem and running the SP could get the data in table sqltblA.
But that's not what I want, I need all rows instead of a certain amount of rows.
Does anyone know what's going on there when I try to CREATE that SP and any solution to it?
Plus I tried to use SSIS as well. When I'm configuring the DataReader source, which uses ADO.NET's ODBC option to connect to mysql, if its sqlcommand is "select * from mytblB" without the Limit key word, then the configuration page will hang there as well and table mytblB is not accessible by using mysql tool. I'm just sick of wasting time on that and that's why I chose to use SP istead of SSIS. But same result. :-(
Hello group,i am relatively new to SQL-Server database, but i have lots ofexperience with DB2 and Oracle Database. One of my tasks is setting upa replication between a Mysql-Database running on Linux and one of ourSQL-Servers.How do i achieve this ?If i understand the documentation correctly you have to program thereplication mechanism for yourself or you have to use some third partytool.Could anyone please outline, how to set up the replication mechanism(pointing me to some web-site should be enough) and also tell me ifthere is any third party tool.Thanks in advance and greetings from ViennaUli
Hi all.I need to set a oneway replication of some data from MSSQL (running underWindows 2000 server) to MYSQL (running under Linux).Do you have some ideas to solve the problem?Thank youLuca
Please help - I am dealing with data transfer from multiple tables to multiple tables - what is the best practice to get this done? So far I have my connection to MySql figured out and I am using a DataReader source to get the data. What is the approriate Data Flow Transformation to pump data into three different tables in MS Sql 2005 database from three different tables in MySlq database? So far I was able to figure out how to do this for one table only...
I need to export tables to a MySQL database. I created an ODBC data source for the MySQL database however not sure how to develop a package to export SQL Server data to MySQL.
