                  </apex:pageBlockSectionItem>

                  <apex:pageBlockSectionItem >

                        <apex:selectRadio value="{!searchCategory}" >

                              <apex:selectOption itemValue="Member__c" itemlabel="Member"/>

            </apex:pageBlockSection>

            <apex:pageBlockButtons location="bottom">

                  <apex:commandButton value="Search" action="{!find}" reRender="result"/>

            </apex:pageBlockButtons>

      </apex:pageBlock>

     

      <apex:pageBlock id="result" >

      <apex:pageBlockTable value="{!result}" var="res">

                  <apex:repeat value="{!objectFields}" var="field">

                        <apex:column value="{!res[field]}"/>

                  </apex:repeat>

      </apex:pageBlockTable>       

      </apex:pageBlock>

     

</apex:form>

</apex:page>

Apex:

public class Search
{

      public String searchKeyWord {get;set;}

      public String searchCategory;

      public List<String> objectFields {get;set;}    

      public sObject sObjectToBind {get;set;}  

      public List<sObject> result {get;set;}

     

      public search()

      {

            searchCategory = 'Member__c';

      }

     

      public void find()

      {    

            /*    Getting fields for the sObject    */

        objectFields =  new List<String>();  

        Map<String , Schema.SObjectType> globalDescription = Schema.getGlobalDescribe();   

        Schema.sObjectType sObjType = globalDescription.get(searchCategory);             

        sObjectToBind = sObjType.newSObject();  

        Schema.DescribeSObjectResult r1 = sObjType.getDescribe();  

          

        Map<String , Schema.SObjectField> mapFieldList = r1.fields.getMap();  

        for(Schema.SObjectField field : mapFieldList.values())  

        {  

            Schema.DescribeFieldResult fieldResult = field.getDescribe();  

            if(fieldResult.isAccessible())  

            {  

                objectFields.add(fieldResult.getName());

            }  

        }  

       

        /*    Building Query with the fields    */

        Integer i = 0;

        String fieldsToFetch = '';

        for(String temp:objectFields)

        {       

            Integer len = objectFields.size();

            if(i==len-1)

            {

                  fieldsToFetch = fieldsToFetch + temp;

            }

            else

            {

                  fieldsToFetch = fieldsToFetch + temp + ',';

            }

            i++;

        }

            String sql = 'Select ' + fieldsToFetch + ' From ' + searchCategory + ' WHERE Name LIKE \'%' + searchKeyword + '%\'';

            result = Database.Query(sql);

      }

     

      /*    Getting and Setting values for SearchCategory radio button    */

      public String getsearchCategory()

      {

            return searchCategory;

      }

     

      public void setsearchCategory(String searchCategory)

      {

            this.searchCategory = searchCategory;

      }
