independent of the database user, and you can treat the schema as a container for the object, which is not the bed, put things. Believe that the concept of container people are already familiar with, such as a new hard disk, we will divide him into N disk characters, C:,d:,e: Ah, and so on, under each drive, we have n folder folders, these are containers.

The reason for the inconsistency between conflicting and subscription data has been found before, and the number of database upgrades that have been discovered is the result of the addition of fields in the publication database and the automatic synchronization of subscriptions. At this point, if the subscription queue has data, the data will be lost. Refer to the previous note: One reason that SQL Server can update subscription data conflicts. When y

Manual repair of fields added in the release and subscription for replication of SQL Server against schema changes Due to previous requirements, the replication architecture changes are prohibited, and even adding a field to the release will not be synchronized to the subscription.

1. Definition: What is the strict mode of MySQL, in short, MySQL itself to strict data validation (format, length, type, etc.), such as an integer field we write a string type of data, in non-strict mode MySQL will not error, Similarly, if a field of char or varchar type is defined, the data that is written or updated exceeds the defined length without an error. I don't think this is any good for programming, although we try to do data validation in the code. MySQL turned on the strict mode from

When a project is under development, the database should be divided into at least two environments: The Development (TEST) database and the formal database. Some projects are even divided into three databases, such as Dev, Stg, and PRD ), how to synchronize Schemas between several databases is a big challenge. The replication function of SQL Server 2005 can synchronize data between databases, but it is difficult to synchronize DDL or
