Arguments

This document lists only arguments pertaining to SQL graph. For a full list and description of supported arguments, see CREATE TABLE (Transact-SQL)

database_name
Is the name of the database in which the table is created. database_name must specify the name of an existing database. If not specified, database_name defaults to the current database. The login for the current connection must be associated with an existing user ID in the database specified by database_name, and that user ID must have CREATE TABLE permissions.

schema_name
Is the name of the schema to which the new table belongs.

table_name
Is the name of the node or edge table. Table names must follow the rules for identifiers. table_name can be a maximum of 128 characters, except for local temporary table names (names prefixed with a single number sign (#)) that cannot exceed 116 characters.

NODE
Creates a node table.

EDGE
Creates an edge table.

Remarks

Creating a temporary table as node or edge table is not supported.

Creating a node or edge table as a temporal table is not supported.

Stretch database is not supported for node or edge table.

Node or edge tables cannot be external tables (no polybase support for graph tables).

Examples

A. Create a NODE table

The following example shows how to create a NODE table

 CREATE TABLE Person (
        ID INTEGER PRIMARY KEY, 
        name VARCHAR(100), 
        email VARCHAR(100)
 ) AS NODE;

B. Create an EDGE table
