Commented Issue: Dynamic queries and combining existing queries [13998]

jrath — Wed, 17 Apr 2013 06:31:22 GMT

First of all, thanks so much for the library. It's been immensely helpful for many projects so far, much better than dealing with CAML strings for sure.

So I'm expecting I'm doing something silly here, but here's the story anyway. Working on CAMLEX 3.3.
I've a pretty typical use case - a simple enough query with a bunch of derivatives. To reduce code, I'm using the dynamic queries syntax to add to the existing query.

So an example base query:
```
var simple = CamlexNET.Camlex.Query()
.Where(
p => p["Hello"] != null
);
```
... and another query to combine:
```
var success = CamlexNET.Camlex.Query()
.WhereAny(
simple.ToString(),
p => p["Test"] != null
);

Console.WriteLine(success.ToString());
```
Which gives you an output like this:
```
<Where>
<Or>
<IsNotNull>
<FieldRef Name="Test" />
</IsNotNull>
<IsNotNull>
<FieldRef Name="Hello" />
</IsNotNull>
</Or>
</Where>
```
However, this technique doesn't seem to work for more complex queries, such as the following:
```
var expiryDate = "ExpiryDate";
var commenceDate = "Commence";
var docFolder = "DocFolder";
var ret = CamlexNET.Camlex.Query()
.Where(
p => (p[expiryDate] == null
|| p[expiryDate] > (CamlexNET.DataTypes.DateTime)CamlexNET.Camlex.Today) &&
(p[commenceDate] == null
|| p[commenceDate] <= (CamlexNET.DataTypes.DateTime)CamlexNET.Camlex.Today)
)
.GroupBy(p => p[docFolder]);
Console.WriteLine(ret.ToString());
```
You'll see that this generates CAML XML just fine, but when you go to add to it using the same method:
```
var problem = CamlexNET.Camlex.Query().WhereAny(
ret.ToString(),
p => p["Test"] != null
);
Console.WriteLine(problem.ToString());
```
The last code chunk returns a "IncorrectCamlException", siting that "Caml specified for tag 'Where' can not be translated to code". I'd suggest it's a bug in the CAML to IQuery translation, because throwing the following XML into camlex-online also fails (yet this is the CAML that is generated by the "ret" query above).

```
<Where>
<And>
<Or>
<IsNull>
<FieldRef Name="ExpiryDate" />
</IsNull>
<Gt>
<FieldRef Name="ExpiryDate" />
<Value Type="DateTime">
<Today />
</Value>
</Gt>
</Or>
<Or>
<IsNull>
<FieldRef Name="Commence" />
</IsNull>
<Leq>
<FieldRef Name="Commence" />
<Value Type="DateTime">
<Today />
</Value>
</Leq>
</Or>
</And>
</Where><GroupBy>
<FieldRef Name="DocFolder" />
</GroupBy>
```

Example inner join List in SharePoint in MSDN

http://msdn.microsoft.com/en-us/library/ee539975.aspx

This will give a huge opportunity, but if use lin-q then problem with large list

Hi

this is excellent framework for CAML.
i got a small problem while i implement Camlex.

var exp = new List<Expression<Func<SPListItem, bool>>>();

exp.Add(x => ((CamlexNET.DataTypes.WorkflowStatus)x[status] == (CamlexNET.DataTypes.WorkflowStatus)ddlStatus.SelectedValue));

the dropdown list values are 2, 16, 17

in run time its giving the error

camlex cannot be translated into caml workflow status

Expression 'x => (Convert(x.get_Item(value(List_View_Filter_WebPart.VisualWebPart1.VisualWebPart1UserControl+<>c__DisplayClass0).status)) = Convert(Convert(value(ASP._controltemplates_list_view_filter_webpart_visualwebpart1_visualwebpart1usercontrol_ascx).ddlStatus.SelectedValue)))' can not be translated into CAML

Comments: hi you need to use string-based syntax - see here. I.e. in your example it should be like this: ``` string s = CamlexNET.Camlex.Query().Where(x => (x["status"] == (CamlexNET.DataTypes.WorkflowStatus)ddl.SelectedValue)).ToString(); ``` It will produce the following Caml: ``` <Where> <Eq> <FieldRef Name="status" /> <Value Type="WorkflowStatus">1</Value> </Eq> </Where> ```

Closed Issue: Add ToSPQuery() [13997]

sadomovalex — Sun, 30 Dec 2012 20:35:08 GMT

Hello,
I really like Camlex and I integrated it into my list based repository I am working on.
Would be really helpfull if you could add ToSPQuery() function.
i.e.:
var q = Camlex.Query().Where(p=>(int)p[ID]==1);
var items = List.GetItems(q.ToSPQuery);

This would save time of declaring new SPQuery and passing query string in.
Thanks for consideration.
Comments: Implemented in version 3.3

Closed Issue: Expression 'x => (ToString(x.get_Item("Тип контента")) = "Заявка")' can not be translated into CAML [13992]

sadomovalex — Sat, 15 Dec 2012 19:31:48 GMT

This is my code:

string caml = Camlex.Query().Where(x => Convert.ToString( x["Тип контента"]) == "Заявка").ToString();

When it comes to its execution I get the following exception:

Expression 'x => (ToString(x.get_Item("Тип контента")) = "Заявка")' can not be translated into CAML

What's wrong with my code?

Closed Issue: Multiple Where clauses on IQuery object are not supported ? [13994]

sadomovalex — Sat, 15 Dec 2012 19:31:32 GMT

The following query with 2 'Where' clauses:
string xml = Camlex.Query()
.Where(x => ((string)x["Title"]).Contains("Visual"))
.Where(x => ((DateTime)x["Created"]) > new DateTime(2010, 09, 01))
.ToString();

creates an XML string containing only the last Where which is not correct!
<Query><Where><Gt><FieldRef Name=\"Created\" /><Value Type=\"DateTime\">2010-09-01T00:00:00Z</Value></Gt></Where></Query>

It should be:
<Query><Where><And><Gt><FieldRef Name=\"Created\" /><Value Type=\"DateTime\">2010-09-01T00:00:00Z</Value></Gt><Contains><FieldRef Name=\"Title\" /><Value Type=\"Text\">Visual</Value></Contains></And></Where></Query>

Please fix this

int[] data = new int[] { 1, 3, 5, 10 };

int[] data2 = data
.Where(i => i < 5)
.Where(i => i > 1)
.ToArray();

// data2[0] = 3
data2.Dump();

Consider the following query. Customer is a field that allows multiple SPUser
<Query>
<Where>
<Or>
<Contains>
<FieldRef Name='Customer' />
<Value Type='UserMulti'>foo</Value>
</Contains>
<Eq>
<FieldRef Name='Requestor' LookupId='TRUE' />
<Value Type='User'>12</Value>
</Eq>
</Or>
</Where>
