Why is SPList.GetItems(SPQuery) returning always the same item to different SPQueries?

Question

Hi,
I have this powershell code:
$url = 'http://artemis/customers' #web URL
$ctx = Get-SPServiceContext 'http://artemis' #site URL
$scope = New-Object Microsoft.SharePoint.SPServiceContextScope $ctx
$web = Get-SPWeb $url
$listSyncZakazky = $web.Lists["bcs_Datis_t_synchronizace_Artemis_zakazky2"]; #BCS to MSSQL 2005 database table
$listMain = $web.Lists["Zakázky"]; #custom SP list
$camlQuery = New-Object Microsoft.Sharepoint.SPQuery
[Microsoft.Sharepoint.SPListItemCollection]$itemsLSyncZakazky = $listSyncZakazky.GetItems()
#foreach ($itemLSyncZakazky in $itemsLSyncZakazky) {
foreach ($itemLSyncZakazky in $listSyncZakazky.Items) {
## happens for both of the ^above^ lines
$camlQuery.Query = "<Where><Eq><FieldRef Name=`"CisloZ`" /><Value Type=`"Text`">" + ($itemLSyncZakazky["cislo_zakazky"]).TrimStart("0") + "</Value></Eq></Where>"
$camlQuery.Query
$camlItems = $listMain.GetItems($camlQuery)
foreach ($item in $camlItems) {
$item["CisloZ"]
$camlItems[0]["CisloZ"]
$web.Dispose()
This returns the following:
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">404</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">300</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">306</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">400</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">200</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">206</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">40303</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">40300</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">40301</Value></Eq></Where></Query>
404
404
<Where><Eq><FieldRef Name="CisloZ" /><Value Type="Text">5801</Value></Eq></Where></Query>
404
404
No matter what I do, from the second item in the collection I get the result from the first one although the CAML query is clearly modified. I tried to create new external content type, have the CisloZ column type as number and text and
no matter what I do I always get the same result.
I use similar code elsewhere and it is working. What could be wrong here?

Hi,
I tried removing $camlItems and it didn't help. Now I moved the $camlQuery
= New-Object
Microsoft.Sharepoint.SPQuery insided the foreach and rremove it at its end and it works now. Thanks!
However this looks like a bug in SPQuery to me.
