For my app users can enter a SELECT statement themselves. This can be any select statement at all, it will be mainly used for creating a quick view e.g. SELECT * from table1 LEFT OUTER JOIN table2 on table1.id = table2.id.
Whatever this select statement maybe I load it into a datatable (after checking for no nasty stuff of course) in vb.net. I want to know the table names so I can query the database again for validation purposes on things like datatypes etc.
da.SelectCommand = New SqlCommand(sqlStatement, tempDB.Connection)
da.MissingSchemaAction = MissingSchemaAction.AddWithKey
dt = New DataTable
da.Fill(dt)

Ok, the basic situation: Due to a few mixed up starts, a project ends up with not one, but three separate databases, each containing a portion of the overall project data. All three databases are the same, it's just that, say 10% of the project was run into the first, then a new DB was made due to a code update and 15% of the project was run into the new one, then another code change required another new database for the rest of the project. Again, the pertinent tables are all exactly the same across all three databases.
Now, assume I wanted to take all three of those databases - bearing in mind that they can't just be compiled into a single databases due to Primary Key issues and so on - and run a single query that would look through all three of them, select a given set of data from each, then compile those three sets into one single result and return it to the reporting page I'm working on.
I have a webbrowser control in VB 2010 Windows Form project that loads a webpage. This webpage contains select tags with a few options. I can select one option using:
Dim

But I need to be able to select more than one option (e.g. 1 and 6) in the select tag/element. Is that possible, the Select element has the multiple select option enabled..
I have a data grid view on a form which is currently filled with the following query:
SELECT TopicCode, TopicName, NoOfCourses, Lev FROM tblTopics WHERE TopicCode = @TopicCode1(Where I obviously pass a TopicCode parameter)
However, I have added two custom columns to the data grid view, and the values that i want be in here are in a different table than the query i'm using to fill the data grid view.is it possible to "nest" queries? which will allow me to select fields from two different tables?
Example:SELECT TopicCode, TopicName, NoOfCourses, Duration, Lev FROM tblTopics AND SELECT StartDate, EndDate FROM tblSubscriptions WHERE TopicCode = @TopicCode1
Possible? or not?
It is possible to check two different MySQL tables from the same sub?

What I'm trying to get is something like an "or" function. If TextBox1.Text isn't in the database, then check if TextBox2.Text or TextBox3.Text is in the database.

View 4 RepliesI have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

I have pulled information from a database into a datatable (dtCustomerInfo) then I expanded on the columns by processing the data and I can display this in a datagridview without any problem. However, the data is in detail and I want to ultimately summarize by customer name.The code below has a commented sql statement that is the statement I ultimately want but it is not working. However, the idea is that I want to Select from one datatable into another but run aggregate sum on several columns so that I will get one record per customer showing totals for each column.So I broke it down to just pull all data possible into the second table.[code]I do know the grouping in the current select * statement does nothing but my issue is more that the columns do not show up.

Tables:

I am trying to return a recordset that gives some summary information about each company. The fields in my returned recordset should look like the following.
Company.Name, NumberOfDepartments, NumberOfEmployees, NumberOfCertificationA, NumberOfCertificationACompleted, NumberOfCertificationB, NumberOfCertificationBCompleted
There are actually about 10 different Certification tables but, with Certification A and B you should get the hang of it. When an employee starts a certifaction, a record is added to the that certification table.Below is a query I wrote that works (gets me the data I need), but I am unsure if it is the most efficient way. There will be quite a lot of data so performance is an issue.

Select c, u).ToList
query (System.Collections.Generic.List(Of )) returns several rows as expected each item containing a c and a u.
How do I iterate through the queries collection?
