[SalesForce] How to get object Prefix from string type of object name

I have following code to return prefix of any object based on API name of object passed as string. :

private static String  getObjectPrefixID(String objName){

        Schema.DescribeSObjectResult r = genericObject.sObjectType.getDescribe();
        String keyPrefix = r.getKeyPrefix();
        return keyPrefix;
    }

I am getting error as:

Initial term of field expression must be a concrete SObject: String

Not sure how to get the prefix ID in this case.

You can do something like

Map<String, Schema.SObjectType> m  = Schema.getGlobalDescribe() ;
system.debug('==>m is==>'+m);
Schema.SObjectType s = m.get('Account') ;
system.debug('==>Sobject Type is ==>'+s);
Schema.DescribeSObjectResult r = s.getDescribe() ;
String keyPrefix = r.getKeyPrefix();
return keyPrefix;

Replace Account with your Object API name.

[SalesForce] Loop through collection

The way that your code reads here

List matchingDataGrid = [Select Id, Name, CreatedById, CreatedDate where Id = :defaultUserID];

    for (List<myData> i :matchingDataGrid.Count)

You are assuming that matchingDataGrid is a list of lists, which it is not. You want to loop over each object within the list, so the format for doing that would be

for(myData i : matchingDataGrid)

The full code would look something like this.

public String matchingDataGridIDs {get;set;}

    public void GetData(string defaultUserID)
    {
        //retrieve data for selected user
        List<myData> matchingDataGrid = [Select Id, Name, CreatedById, CreatedDate where Id = :defaultUserID];

        for (myData i :matchingDataGrid)
        {   
            matchingDataGridIDs += i.Id + ',';
        }
}

[SalesForce] record type name insert in test class

You get record type Id, you cannot extract name from it.

RecordType rt = [SELECT Id FROM RecordType WHERE sObjectType = 'Assignment__c' AND Name = 'Lead_Opportunity_Rule'];
...
objass.RecordType = rt;
// OR
objass.RecordTypeId = rt.Id;
