There is a database connection error, which could be due to incorrect database connection information configuration or the database being unavailable, causing the table to not be saved.
Insufficient permissions: The currently logged-in user does not have enough authority to create tables and must contact the database administrator to grant the necessary permissions.
Duplicate table name: The table name you are trying to create already exists in the database, please use a different table name to save the new table.
The database version may be incompatible with Navicat, causing the inability to save tables.
There is a syntax error in the SQL statement used to create the table, which is preventing the table from being successfully saved.
Insufficient storage space in the database: The database is either full or does not have enough space to store new tables.
There is a conflict in the database table structure: the existing table structure conflicts with the new table structure, and the structure of the new table needs to be adjusted to meet the requirements of the database.
Other unknown reasons: There may be other unknown issues preventing the table from being saved, requiring further investigation and debugging.
