Transaction operations

• Execute transaction

Transaction operations are focused on executing transactions. These operations are accessible through Transaction property in database context object.

Execute transaction

Executes specified transaction.

Applicable optional parameters available through fluent API:

• ReadCollection(string collectionName) - Maps read collection to current transaction.
• WriteCollection(string collectionName) - Maps write collection to current transaction.
• WaitForSync(bool value) - Determines whether to wait until data are synchronised to disk. Default value: false.
• LockTimeout(int value) - Determines a numeric value that can be used to set a timeout for waiting on collection locks. Setting value to 0 will make ArangoDB not time out waiting for a lock.
• Param(string key, object value) - Maps key/value parameter to current transaction.

var db = new ArangoDatabase("myDatabaseAlias");

var transactionResult = db.Transaction
    .WriteCollection("products")
    .Execute<int>(@"
    function () { 
        var db = require('internal').db; 

        db.products.save({ });

        return db.products.count(); 
    }
    ");
    
if (transactionResult.Success)
{
    var documentsCount = transactionResult.Value;
}
