The community member is asking if anyone has created or has knowledge of a "RetrySQLQueryEngine" - a tool that can retry generating a proper SQL statement if the initial statement errors out. In the comments, another community member suggests exploring a workflow example for "Text-2-sql" from the llama_index project, which may help in the same direction. The community members discuss the use of workflows in the llama_index project and the need to explore them further, but there is no explicitly marked answer to the original question.
