Databases :: Play Around With Column's Names Filled By OleDbDataAdapter?
May 3, 2010
I tried to query an excel file which contains a lot of customers' information but my problem is most of those don't have a specific column names. E.g. it's in the following format. (Excel File)
A B C
Info1 blur blur
Info2 blur blur
Info3 blur blur
So, when I query using SqlDbDataAdapter, in my DataTable, info1 blur blur becomes column header. e.g. it's in the following format. (DataTable)
Info1 blur blur
Info2 blur blur
Info3 blur blur
I been working on it so that it actually goes down one row and Change the column name in the DataTable into some appropiate name. Something like the following format.
Is there any way that I could work around it rather than actually going back to change the excel files ? Because I have like 1,000 excel files in that kinda format and seriously giving me headache now.
What I have is a datatable being constructed from Sharepoint API. We dont need to worry about the sharepoint api.The code where it fills the data is as follows
Datatable dt = new datatable(); Sharepoint.fill(dt);
Write what I want is as the dt is being filled is to create another column called full path which has a formula col1+col2I dont want to do a for next loop after the dt is filled . very slow !
I'm using a DataSet to fill my gridview. The dataset contains several columns, like: direction - fromNumber - toNumberThe column direction can contain the values "incoming" or "outgoing". In my gridview, I would like to show only 2 columns, direction and from/to. If direction = "incoming", the values from fromNumber has to be inserted in "from/to". If direction = "outgoing", the values from toNumber has to be inserted in "from/to".I know I can use a TemplateField to show different text values in a column...But I have no idea how to do this when I want to show the values from a column...
I have the following code i found online and it works fine as long as the sheet names are simple names it seems..
If i have a excel file with a sheet name of (sheet1) the code works.. but if i have a file with a sheet name like (FileName2011_03_03_15_01_43) it fails and causes the rest of my code not work..
I have a database with two columns: Retailers or Traders. A row can have only one of them with values while the other must be 'Null'. Both are nvarchars kinds. What I am trying to do is to show data if a radio button is selected for either Retailer or Trader. So I constructed a SelectCommand statement which is getting column names of either 'Retailers' or 'Traders' as a parameter but the SelectCommand statement still returns all records. What can I do?
I am getting a datatable from the SQL Server. In SQL Server the column headers are fine (mix of Capital and Small Letters). But when i am getting it in the front end, all the column names are in lower case. How can i get the column names in original Case.
I have an ASP ListView which I am using to display some pivoted information (across years) in a table. Currently I have the ListView templates defined as:
SELECT SRFILE_1.SRCONMAE, COUNT(LBWF_1.Incidentx) AS SLAFailed, (SELECT COUNT(Incidentx) AS Expr3 FROM LBWF AS LBWF_2) AS TotalCalls FROM SRFILE AS SRFILE_1 INNER JOIN LBWFAS LBWF_1 ON LBWF_1.Incidentx = SRFILE_1.SRONUMBER WHERE (LBWF_1.KPIFailx = '1') OR (LBWF_1.Chargex > '0.00') OR (LBWF_1.LChargex > '0.00') GROUP BY SRFILE_1.SRCONMAE
What I'm trying to do is divide TotalCalls by SlaFailed and * by 100 into a new variable such as Percentage. However, everytime I try to select SLAFailed or TotalCalls I receive a 'Column Names do not exist' message.
I've created a Dynamic Data project with an Entity Framework model. It works nicely. But, right now it shows all my database tables with the db column names - which aren't always the most friendly (e.g. address_line_1). How can I got about giving these more friendly column titles that will display to the end user?
