Hi All,
i'm use the OrientDb batch rest api to interact with my OrientDB database.
Now i have a specific need.
i want create a vertex only if this vertex not exists.
Then i write this lines of code with the IF condition but the statement in
the if condition is never executed. How is possible test if the root_node
not exist and then create it? This is my postData code
var postData = JSON.stringify({ "transaction" : true,
"operations" : [
{
"type" : "script",
"language" : "sql",
"script" : [
"LET root_node = SELECT FROM PowerSolution WHERE
Site_User ='" + message.Site_User + "' AND uuid = '"+ message.StartTime +
"'",
"IF($root_node IS NULL){",
"LET new_root_node = CREATE VERTEX PowerSolution SET
Site_User ='" + message.Site_User + "', uuid = '"+ message.StartTime + "'",
"}"
]
}
]
});
Also with $root_node == NULL condition the result don't change
Any suggestion will be appreciated.
Thanks in advance.
Best regards and happy new year
Leo
