How to use DataTable.Select() when the DataColumn.ColumnName contains a space?
I have a DataColumn that contains an space and I just couldn’t get the DataTable.Select(“Column Name=value) function to work.
So i found a solution on some other guys wordpress blog here.
The answer should be obvious to those who use SQL. In SQL to use a space, it often adds square brackets around the column names. [Column Name]. Yes, using square brackets is the solution.
String colName = "Column Name";
String Value = "some data";
DataTable.Select("[" + colName + "]='" + value + "'");
can anyone help me how to fix this… i should get records because id is greater than 1
Dim d As New DataSet2
Dim table As DataTable = d.Tables(“ClientsPersonal”)
‘ Presuming the DataTable has a column named Date.
Dim expression As String
expression = “id > 1”
Dim foundRows() As DataRow
‘ Use the Select method to find all rows matching the filter.
foundRows = table.Select(expression)
MsgBox(foundRows.Count)
Dim i As Integer
‘ Print column 0 of each returned row.
For i = 0 To foundRows.GetUpperBound(0)
MsgBox(foundRows(i)(0))
Next i
Where are you populating the table from? Are you populating from a database or elsewhere? Can you verify that the table is populated?
I see that you run Table.Select(), but that doesn’t populate the table, it queries an already populated table.
Assuming your table is populated, I cannot see a problem with the syntax, though I am a C# more than vb guy.
