Question
%ngql INSERT VERTEX table(name) VALUES 'abc':('abc');
%ngql INSERT VERTEX column(name) VALUES 'column_xyz':('xyz');
%ngql CREATE EDGE IF NOT EXISTS has_column(has_column STRING);
%ngql INSERT EDGE has_column() VALUES "abc"->"column_xyz": ();
UsageError: unrecognized arguments: ->"column_xyz": ();

I had tried with multiple syntaxes can you please provide me a solution related to this.

Hello @wey-gu,

From your question, it seems like you're having trouble with the syntax for inserting an edge in ngql. The error message you're seeing typically indicates that the arguments provided to a function or method do not match the expected parameters.

Based on the ngql commands you've provided, it seems like you're trying to insert an edge between two vertices. The correct syntax for inserting an edge in ngql is as follows:

INSERT EDGE edge_type(prop_name) VALUES start_vertex_id -> end_vertex_id: (prop_value);

In your case, the command should look something like this:

INSERT EDGE has_column(has_column) VALUES 'abc' -> 'column_xyz': ('value');

Please replace 'value' with the actual value you want to insert.

Also, please ensure that the vertices 'abc' and 'column_xyz' exist before you try to insert an edge between them. If they don't exist, you'll need to create them first using the INSERT VERTEX command.

I hope this helps! If you have any other questions, feel free to ask.

Sorry looks like a iPython-ngql bug triggerred, you could mitigate this via %%ngql for multiple queries for now.

%%ngql
INSERT EDGE has_column() VALUES "abc" -> "column_xyz": ();

I'll fix this later in wey-gu/jupyter_nebulagraph#5

Thanks!
