Steps are almost similar to create an external table for MongoDB as it is for SQL and Oracle. Let us view the steps. 为MongoDB创建外部表的步骤几乎与为SQL和Oracle创建外部表的步骤相似。 让我们查看步骤。 CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password@123'; 1. CREATE DATABASE SCOPED C...

To work around this, always explicitly create the local temporary table in a query without any parameters. As a special case, the driver will then be able to execute the query directly on the connection-scoped session. The following example works: ...
