Root Cause

Attempting to run GRAPH.QUERY on a non-existent graph key without prior GRAPH.CREATE call.

generic

中文

尝试对不存在的图键执行 GRAPH.QUERY，而未先调用 GRAPH.CREATE。

Workarounds

  1. 95% success Create the graph first: GRAPH.CREATE mygraph. Then retry GRAPH.QUERY mygraph 'MATCH (n) RETURN n'. 
    Create the graph first: GRAPH.CREATE mygraph. Then retry GRAPH.QUERY mygraph 'MATCH (n) RETURN n'.
  2. 85% success If using RedisGraph v2.12+, enable auto-create: CONFIG SET graph.auto_create 1. Then GRAPH.QUERY will auto-create the graph. 
    If using RedisGraph v2.12+, enable auto-create: CONFIG SET graph.auto_create 1. Then GRAPH.QUERY will auto-create the graph.

中文步骤

  1. 先创建图：GRAPH.CREATE mygraph。然后重试 GRAPH.QUERY mygraph 'MATCH (n) RETURN n'。
  2. 如果使用 RedisGraph v2.12+，启用自动创建：CONFIG SET graph.auto_create 1。然后 GRAPH.QUERY 将自动创建图。

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Using GRAPH.QUERY with a non-existent graph name will auto-create it in some versions, but not in strict mode; this behavior is version-dependent and unreliable.

  2. 80% fail

    Renaming the graph key with RENAME will fail if the key doesn't exist; it doesn't solve the missing graph issue.
