Filter Collection

  • 1.  Filter Collection

    Posted 12-10-2018 21:17
    I am having issue filtering a collection that has a column name with space. I get the following error: Internal : Could not execute code stage because exception thrown by code stage: Syntax error: Missing operand after 'Name' operator.   I have attached picture for reference.

    Try enclosing First Name in single quotes as well.

    Using single quotes does not work, it does get rid of the error message but it does not give the right output result.

    Try making a new action with this as the code stage. I replaced that action with this one for ease of use long ago.

    Inputs:
    Collection - Collection
    FilterString - Text
    Column - Text

    Outputs:
    Sorted Collection - Text  

    String filter = """";
if(FilterString!="""") 
{
	filter = ""`""+Column+""`"" + "" like '%""+FilterString+""%'"";
}
else
{
	filter = ""`""+Column+""`"" + "" = ''"";
}
DataView dv = Collection.DefaultView;
dv.RowFilter = filter;
Sorted_Collection = dv.ToTable();

    Hello, Try using in this format in Filter Attribute in ""Utility - Collection Manipulation"" , as Coll1.First Name = ""White Shark"" and check it. Good Luck.

    Enclose that column name within square brackets.

    I had this problem many times until I found a simple and easy solution. When filtering with VB.net codes the column name is typically put in brackets. "[Column Name] LIKE 'text you want to filter'" The [ ] will allow you to use a space. Make sure Quotation marks are used before the [ as blue prism will think you are referring to a data item if you don't.

    Either [ ] or ` `. Basic SQL notation.

    ​Hi all,

    any Idea why ? wildcard is not working?

    eg.: [Area] like '04? AB'

    I guess I haven't ever tried using a wildcard in the middle of a filter expression. You'd think I'd need that at some point. Go figure. =)

    Blue Prism is using the Select method on the datatable to filter the results (that is, if you go all the way into the code stage), and it looks like the Select method only supports wildcards at the beginning or end of the text such as '*this*'. I suppose the other issue here is that the Select method doesn't seem to support ? as a wildcard. I haven't looked into whether there's another single character to use instead, but at least when used in Blue Prism, the ? is read as part of the string.

    Y    ou may want to use LINQ instead. It seems to be the go-to when performing queries on datatables (collections) in Blue Prism beyond what the existing actions provide.

    I was just thinkig it has same possibilities like show on this page: https://www.w3schools.com/sql/sql_wildcards.asp

    i have very small knowledge about SQL, but i will try to find some solution. I will check the LINQ. It will come handy to have a better possibilites for filtering. At least in my projects :)

    Thanks for your reply

    Because DataTable is not a real database and wildcards in the middle just doesn't work as documented.
    You can use something like this sometimes: [Area] like '04%' and [Area] like '% AB'
    But keep in mind this is not the same thing.

    Custom action filtering rows one by one with regex condition would work.

    You could always use another code stage to execute a custom query against it.

    Inputs:
    Collection - Collection
    Query - Text

    Outputs:
    Sorted Collection - Collection

    DataTable temp = Collection.Clone();
DataRow[] dr = Collection.Select(Query);
foreach(DataRow row in dr)
{
	temp.ImportRow(row);
}
Sorted_Collection = temp;​
