The previous data appearing when connecting to Navicat may be due to: 1. Previous connection cache; 2. Automatic connection; 3. The connection string specifies a specific schema. Workaround: Clear the connection cache, disable automatic connection, edit the connection string, or select the schema manually.
The reason why previous data appears when Navicat creates a new connection
When using Navicat to establish a database connection, if the connection is found contains previous data, which may be due to the following reasons:
1. Records of previous connections:
- Navicat will cache previously established connection information, including Database credentials and schema. When establishing a new connection, Navicat may automatically load previously cached data if the same database as the previous connection is used.
2. Automatic connection:
- If Navicat's automatic connection function is enabled, Navicat will automatically connect to the most recently used database. When establishing a new connection, Navicat may automatically load the previous data if the target database is the same as the automatically connected database.
3. Connection string:
- Specifies a specific schema in the connection string. If the DEFAULT_SCHEMA option is included in the connection string, Navicat will connect to this schema by default.
Solution:
- Clear the connection cache: Close Navicat, and then delete "Connections" in the Navicat installation directory folder. After restarting Navicat, the previous connection information will be cleared.
- Disable automatic connection: In Navicat's preferences, disable the "Automatic Connection" function.
- Edit the connection string: Edit the connection string to ensure that no specific schema is specified.
- Manually select schema: After establishing the connection, manually select the required schema in Navicat's connection tree.
