This is because the database into which the table is to be imported is not specified. If you directly click the file in the upper left corner of the database->Open->File, the query bar in the upper left corner of the database is gray, and you cannot click execute to import the table into the newly created database. When a file is generated after the tables are successfully exported from PowerDesigner, we need to create a new database to receive these tables. A tag is automatically generated when a table has a primary key, so the problem may be that the primary key box was not checked when the table was created, which led to this error. The foreign key of PowerDesigner is automatically generated based on the table connected by the primary key, so there is a problem with the primary key. The table and the table are connected through the primary key and foreign key.
This type of error is reported because the referenced connection does not exist, that is, the connection between the table and the table is invalid. After the errors are automatically corrected, the database can be re-exported. At this time, the fourth item will have an Automatic Correction, which will automatically correct the error according to the template in the system. We first select the place where the error is reported and click the right button. The system has a solution for this problem. As the name implies, it is a conflict caused by the same names in some fields of the table. This error Chinese translation is to restrict the uniqueness of the name.
There are several common types of errors below.
