Question
How is the & symbol handled in the following query in oData?
/vendordataservice.svc/vDataMapper_SourceMapVendor?&$filter=startswith(ParentName,'AT&T')&$top=7&$skip=0
I'm using EF3.5 and SQL2008. When I send that to my oData service I get no data back.
Solution 2
Here is a list of characters that should be encoded prior to sending to SQL server over HTTP:

Yes, the '&' symbol is one of them.
OTHER TIPS
Do not use the “JavaScript String replace() Method”. It will replace the first occurrence of the special characters. if you have 2 occurence of the same special characters in the filtering parameter, it will fail. So use the regular expression to replace the characters.
function replaceSpecialCharacters(attribute) {
// replace the single quotes
attribute = attribute.replace(/'/g, "''");
attribute = attribute.replace(/%/g, "%25");
attribute = attribute.replace(/\+/g, "%2B");
attribute = attribute.replace(/\//g, "%2F");
attribute = attribute.replace(/\?/g, "%3F");
attribute = attribute.replace(/#/g, "%23");
attribute = attribute.replace(/&/g, "%26");
return attribute;
}
Also pay attention, since the replacements also contains %
then %
it self should be replaced at beginning
