How to filter a dataview
I have a dataview that contains a list of tables. I am reading in a list of values that I then want to apply as a filter to this dataview. The list of values is actually in the form of "table1, table2, table3". So I thought I would be able to use this as a filter on my dataview.
SqlOp.CommandText = "select name from dbo.sysobjects where xtype='u'";
SqlOp.ExecuteDataReader();
DataView dv = SqlOp.GetDataAsDataView();
SqlOp.CloseConnection();
Returns a list of all the tables in a dataview. Any help on how to filter this dataview?
Edit:
Not sure if I was completely clear in what I seek to accomplish. To clarify, I am trying to figure out how/if.RowFilter
will help me in filtering this dataview. S开发者_StackOverflowomething like:
dv.RowFilter = "name IN (table1, table2, table3)" // I know this doesn't work
You have to use like statement
"select name from dbo.sysobjects where xtype like 'u%'"
As well use Parameters collection

I figured out the .RowFilter
issue:
dv.RowFilter = "name IN ('table1', 'table2', 'table3') // missing the single quote surrounding table names
