[英]Importing SQL Server SQL_VARIANT data type to OrientDB vertex - which property type should I use?
I am evaluating OrientDB as a replacement for MS SQL Server. 我正在评估OrientDB作为MS SQL Server的替代品。 One of the SQL Server tables I need to import into OrientDB contains time-series data with the value column using a SQL_VARIANT data type.
我需要导入OrientDB的SQL Server表之一包含使用SQL_VARIANT数据类型的value列的时间序列数据。 I'm struggling to identify the best data type to use for the equivalent property in a new OrientDB vertex.
我正在努力确定最佳的数据类型,以用于新的OrientDB顶点中的等效属性。 I'm hesitant to convert it a STRING, but I don't see an equivalent variant type.
我不愿意将其转换为STRING,但没有看到等效的变体类型。 Any recommendations?
有什么建议吗?

但要注意:在社区版中,您可以迁移源关系数据库,但不能享受仅在企业版中可用的同步功能。
