Joining tables through views in Navicat enables convenient data access and query: create views and use SQL statements to join the required fields together from different tables. To connect the view, drag and drop the created view into the query editor. Execute the query, enter the SQL query and execute it to view the connected data.
Use views to connect tables in Navicat
In the Navicat data management tool, you can connect different tables through views Connect to easily access and query data. The following are the specific steps:
1. Create a view
- Right-click the database name and select "New" > "View".
- In the "View Editor", enter the following SQL statement:
CREATE VIEW 视图名称 AS SELECT 字段1, 字段2, ... FROM 表名1 LEFT JOIN 表名2 ON 表名1.字段1 = 表名2.字段2 ...
- Modify field 1, field 2, etc. as the fields to be connected, modify table names 1, Table name 2 and so on are the tables to be connected.
2. Connect the view
- Expand the database in the database tree and find the created view.
- Drag and drop the view into the query editor.
- The view will be joined as a table in the new query.
3. Execute query
- Enter the SQL query to be executed.
- For example:
SELECT * FROM 视图名称
4. View the results
- After executing the query, Navicat will display all the data contained in the view .
Example
Suppose there are the following two tables:
- Employee table (Employee): ID, name, department
- Department table (Department): ID, department name
To create a view connecting these two tables, you can use the following SQL statement:
CREATE VIEW EmployeeDepartment AS SELECT e.ID, e.Name, e.DepartmentID, d.DepartmentName FROM Employee e LEFT JOIN Department d ON e.DepartmentID = d.ID
Then, You can drag and drop the EmployeeDepartment view in the query editor and execute the query to view the joined data.
