Split String

Is it possible to pick values ​​between SELECT and FROM (String) and use the code in Apex?

Example: the user informe = SELECT casenumber,subject,Contact.Name,status FROM Case WHERE ClosedDate=TODAY
The Apex code uses only: casenumber, subject, Contact.Name, status to build a CSV::::

...
string titre= 'casenumber,subject,Contact.Name,status'+'\n';

...

for(Case a: (List<case>)database.query(caseTT) )
{
   string contenu = a.casenumber + ',' + a.subject+ ',' +a.Contact.Name+ ',' + a.status +'\n';
   contenuCSV = contenuCSV + contenu ;
}

....

Thank you!!!

Hello Veronica,


maybe you can use the get() method for Case records. Something like:

List<Case> listCases = database.query(caseTT);

String[] listFields = calculateListFields(caseTT); //calculateListFields would be a method returning String[], where each element will be a field API name: 
                                                                            //casenumber, subject, contact.name....
String contenuCSV = '';
for(Integer i = 0; i<listCases.size(); i++){
     String csvRow = null;
     for(String s : listFields){ //Build a row of the csv file
        if(csvRow == null){
             csvRow = listCases[i].get(s);
        }
        else{
             csvRow += ',' + listCases[i].get(s);
        }
     }
     csvRow += '\n';
     contenuCSV += csvRow;
}

Best regards,

Gonzalo.

Hi veronica,

You can split by using 

substringAfter and substringBefore methods.

eg:
string query = 'SELECT casenumber,subject,Contact.Name,status FROM Case WHERE ClosedDate=TODAY';
string First =query.substringAfter('SELECT');                // SELECT is caps because its case- sensitive
First =  First.substringBefore('WHERE');                    // WHEREis caps because its case- sensitive
system.debug('~~~~~~~~'+First);

Mark this as solution if you got a answer.

Thanks.

Thank you my friends!
I will try...
marys pindamarys pinda
I tried using a regular expression, but it is giving errors!
Any tips?

Thank you

....
//Value informed into Visualforce Page
public string caseTT {get; set;}

....

public void planifier(){
//string titre= 'Id, Subject,Demandeur,Status'+'\n';
string contenuCSV = '';
Matcher pm = Pattern.compile('(?<=select)(.*)(?=from)').matcher( caseTT );
List<Case> listCases = database.query(caseTT);
String[] listFields = pm;

for(Integer i = 0; i<listCases.size(); i++){
     String csvRow = null;
     for(String s : listFields){ 
        if(csvRow == null){
             csvRow = listCases[i].get(s);
        }
        else{
             csvRow += ',' + listCases[i].get(s);
        }
     }
     csvRow += '\n';
     contenuCSV += csvRow;
}

Hi ,

You can use substringAfter and substringBefore methods as Praveen mentioned.
They are a lot easier to use and no need to maintain expressions.

Thanks
marys pindamarys pinda
It really is easier ... but how do I do the following next step?

for(Case a: (List<case>)database.query(caseTT) )
{
   string contenu = a. casenumber  + ',' + a.subject+ ',' +a.Contact.Name+ ',' + a.s tatus +'\n';
   contenuCSV = contenuCSV + contenu ;
}

Thank you!

Hi,

If I understood question correctly, my answer is 

String fieldValues = '';
        SObjectType objectType = Schema.getGlobalDescribe().get(case);
        DescribeSObjectResult objDesc = objectType.getDescribe();
        Map<String, SObjectField> fields = objDesc.fields.getMap();
        Set<String> fieldSet = fields.keySet();
        for(String f : fieldSet)
        {
            fieldValues += f +',';
        } 
        if(fieldValues.endsWith(','))
        fieldValues= fieldValues.substring(0,fieldValues.length()-1);

// here field values will hole the all the field in Object Case.

Thanks

Hi veronica,

The object name should be in single quotes and if its a custom object you need add __c at the end.

Eg.

String contenuCSV = '';
        SObjectType objectType = Schema.getGlobalDescribe().get('caseTT__c');
        DescribeSObjectResult objDesc = objectType.getDescribe();
        Map<String, SObjectField> fields = objDesc.fields.getMap();
        Set<String> fieldSet = fields.keySet();
        for(String f : fieldSet)
        {
            contenuCSV += f +',';
        }
        if(contenuCSV .endsWith(','))
        contenuCSV = contenuCSV.substring(0,contenuCSV .length()-1);

Mark this as solution if you got a answer.

Thanks.

Hi,

I think the error is coming from some other place,

I have checked through developer console with account object.

String contenuCSV = '';
        SObjectType objectType = Schema.getGlobalDescribe().get('Account');
        DescribeSObjectResult objDesc = objectType.getDescribe();
        Map<String, SObjectField> fields = objDesc.fields.getMap();
        Set<String> fieldSet = fields.keySet();
        for(String f : fieldSet)
        {
            contenuCSV += f +',';
        }
        if(contenuCSV .endsWith(','))
        contenuCSV = contenuCSV.substring(0,contenuCSV .length()-1);
system.debug('~~~~~~~~'+contenuCSV);

Its worked fine.

I do not know what's wrong with my code ...
I'm trying to figure out!

Thank you
marys pindamarys pinda
Is it possible to do this part to be dynamic and not static?


for (Case a: (<case> List) database.query (caseTT))
{
    a.casenumber string contenu = + ',' + a.subject + ',' + a.Contact.Name + ',' + a.status + '\ n';
    contenuCSV = contenuCSV + contenu;
}

something like:

for(ValueInformedInputTexVisualforcePage a: (List<ValueInformedInputTextVisualforcePage>)database.query(caseTT) )
{
   string contenu = a.ValueInformedInputTexVisualforcePage + ',' + a.ValueInformedInputTexVisualforcePage + ',' +a.ValueInformedInputTexVisualforcePage+ ',' + a.ValueInformedInputTexVisualforcePage +'\n';
   contenuCSV = contenuCSV + contenu ;
}

Thank you!

Hi,

String contenuCSV = '';
        SObjectType objectType = Schema.getGlobalDescribe().get('Account');
        DescribeSObjectResult objDesc = objectType.getDescribe();
        Map<String, SObjectField> fields = objDesc.fields.getMap();
        Set<String> fieldSet = fields.keySet();
        for(String f : fieldSet)
        {
            contenuCSV += f +',';
        }
        if(contenuCSV .endsWith(','))
        contenuCSV = contenuCSV.substring(0,contenuCSV .length()-1);
Messaging.EmailFileAttachment csvPJ = new Messaging.EmailFileAttachment();
blob csvBlob = Blob.valueOf(contenuCSV);
string csvNom = 'cases_fermes.csv';
csvPJ.setFileName(csvNom);
csvPJ.setBody(csvBlob);
Messaging.SingleEmailMessage email =new Messaging.SingleEmailMessage();
String[] adressMail = new list<string> {'ppraveenm@gmail.com'};
String subject = 'CSV';
email.setSubject(subject);
email.setToAddresses( adressMail );
email.setPlainTextBody('mail .....');
email.setFileAttachments(new Messaging.EmailFileAttachment[]{csvPJ});
Messaging.SendEmailResult [] envoyer = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});

I have tested this code with developer console and i have received mail. if you see here mail address is manually entered.

So I think the issue is on public String mailSouhaite {get; set;}
public string caseTT {get; set;}  pls check this.

I do not understand where you wrote your request.
I need a Visualforce page to get the request from the input text (caseTT).
Where will you inform your request to use within Apex code?

Thank you!!!
