How to select all fields from SObject thro SOQL?

Hi All,

I need to select all the fields ( like accountName, accountNumber etc ) of Account ( or any sobject ) through SOQL.

I constructed the select qurey as follows.

DescribeSObjectResult res = binding.describeSObject( "Account" );
Field[] fields = res.getFields();
String expr = "";
for( int i=0; i < fields.length-1; i++ )
{
expr += fields[i].getName() + ", ";
}
expr += fields[ fields.length - 1 ].getName();

String qry = "Select " + expr + " from Account";
QueryResult res = binding.query( qry );

While executing this, I am getting following exception.

Is there any easier way to achieve this!

Kindly help me solve this problem!

Regards,
Ganesh Kumar N.S.A

Hi ganesh,

Looks like the error is on the client side serializer.  First, though, there is no select * syntax available.  You are approaching the problem correctly by creating a comma delimeted list of fields from the describe call.

I would put a debug statement to print the entire SOQL statement.  Then examine it closely to make sure that it is correct.  (I'm fairly confident that you statement is well formed based on your code snippet.)

I would also like to know which soap stack you are using and find out if there are any string length limitiations being imposed.  It may be that the length of the SOQL statement is causing the soap stack to gack.  (seems silly, but could happen).  Try doing half the fields and see if you get the same exceptions.

If you have the option, I would use Axis 1.1 libs.

Cheers

Any updates on the "SELECT * FROM..." syntax? This would be a very helpful feature.

No, you still need to explictly indicate which fields to want to query.

Could be useful if you promote this idea (if you haven't done it yet):

Alo again.... Im in the same, just saw solution, Ill do it then...but, tell me why there's no select * from... just to keep my peace of mind.

 

thank u

This is utterly ridiculous, select * should have been implemented day one.

Abused or not, governors are enough pain/limitation considering the costs to build a platform on force.com

Maybe, i am posting a reply here after a long time. Anyhow, wanted to share the reason i think why "select *" is not available..

 

As far as i know each Sobject(Account,Contact etc) is not a actual database table. Each table that you actually query using SOQL is actually a VIEW of the master table..  So, basically one MASTER TABLE and many VIEWS (each per org per Sobject)..

 

Dat's the reason you cannot have a Select *. I dont know if there is a way to overcome this even if Salesforce likes to.

I posted a workaround for this on my blog using Apex. Perhaps something similar can be done in Java.  The method involves using the Schema.getGlobalDescribe() method to get fields on an object and then dynmically generate a query string with all the fields.

 

Hope this is helpful,

Hi I hope this will help.

/*
* @description: A code snippet that mimics the popular Select * SQL syntax in force.com's Apex language.
*/

// Initialize setup variables
String objectName = 'Contact';  // modify as needed
String query = 'SELECT';
Map<String, Schema.SObjectField> objectFields = Schema.getGlobalDescribe().get(objectName).getDescribe().fields.getMap();

// Grab the fields from the describe method and append them to the queryString one by one.
for(String s : objectFields.keySet()) {
   query += ' ' + s + ', ';
}

// Manually add related object's fields that are needed.
query += 'Account.Name,'; // modify as needed

// Strip off the last comma if it exists.
if (query.subString(query.Length()-1,query.Length()) == ','){
    query = query.subString(0,query.Length()-1);
}

// Add FROM statement
query += ' FROM ' + objectName;

// Add on a WHERE/ORDER/LIMIT statement as needed
query += ' WHERE firstName = \'test\''; // modify as needed
 
try {
        List<Contact> contacts = database.query(query);
} catch (QueryException e){
        //perform exception handling
}

Hi Ganesh,

To achive this you can use like this

DescribeSObjectResult res = binding.describeSObject( "Account" );
Field[] fields = res.getFields();
String expr = "";
for( int i=0; i < fields.length-1; i++ )
{
expr += fields[i].getName() + ", ";
}
expr += fields[ fields.length - 1 ].getName();

String qry = "Select " + expr + " from Account";

QueryResult res = binding.query( qry );

For the second question

You cant do in direct way. As Ramu's saidf you should use  dynamic query.

Thanks,

Praveen Murugesan

Use the Schema Browser in the Force.com IDE to quickly construct a    SOQL query that will return all fields.
Mark ThomsonMark Thomson
An easy way to get the field list in an SOQL object is to use the extract feature of the Apex Data Loader.  When you build an extraction and select all fields a select query is built for you.

Hi Praveen,
Can you please explain what is DescribeSObjectResult res = binding.describeSObject( "Account" ); ?
and how to create DescribeSObjectResult res = binding.describeSObject( "Account" ); in scala+spark.

Thanks

You can try: 
Account acc = Database.query('SELECT ' + String.join(new List<String>(Schema.getGlobalDescribe().get('Account').getDescribe().fields.getMap().keySet()), ',') + ' FROM Account');
By this way, you get all the fields of your object.
BraneBrane
Starting from Spring '21 Release (API v51+) adds new SOQL FIELDS function can select all fields of an object. Refer to documentation
Knowing that new FIELDS function must have a LIMIT of at most 200.

Example: 
SELECT FIELDS(ALL) FROM Account LIMIT 200
