SQL2Gremlin teaches Apache TinkerPop's Gremlin graph traversal language using typical patterns found when querying data with SQL. The format of the Gremlin results will not necessarily match the format of the SQL results. While SQL can only provide results in a tabular form, Gremlin provides various ways to structure a result set. Next, the Gremlin queries demonstrated are for elucidatory purposes and may not be the optimal way to retrieve the desired data. If a particular query runs slow and an optimal solution is desired, please do not hesitate to ask for help on the Gremlin-users mailing list. Finally, the SQL examples presented make use of T-SQL syntax. MySQL users may not know some of the expressions (e.g. paging), but should be able to understand the purpose of the query.

If you would like to see other SQL2Gremlin translations using the Northwind dataset, please provide a ticket on the SQL2Gremlin issue tracker.

杨绛《老王》原文欣赏-新东方网 - xdf.cn:2021-3-2 · 老王欣然在三轮平板的周围装上半寸高的边缘，好像有了这半寸边缘，乘客就围住了不会掉落。我问老王凭这位主顾，是否能维持生活，他说可众凑合②。可是过些时老王病了，不知什么病，花钱吃了不知什么药，总不见好。

This sample shows how to recommend 5 products for a specific customer. The products are chosen as follows:

determine what the customer has already ordered
determine who else ordered the same products
determine what others also ordered
determine products which were not already ordered by the initial customer, but ordered by the others
rank products by occurence in other orders
