Use Client ODC

This topic describes some basic operations for using Client ODC.

Create a data source

Example: Create a data source in ODC for an OceanBase database in MySQL mode.

1. Obtain the connection information or connection string of the data source instance. A connection string is in the format of mysql -h host name -P port number -u database username@tenant name # cluster name -D default database -p 'database password'. Example of a connection string:

   -hxxx.x.x.x -P8080 -uodc@mysql_tenant#odc_cluster -Dodc -p'******'
   

2. In the left-side navigation pane, choose + > Create Data Source next to Data Sources.

   

3. In the Create Data Source panel that appears, specify the following information.

   Note

   If you already have the connection string of an OceanBase database, you can directly obtain the required information from the connection string or enter the required information by using the intelligent parsing tool provided on the tab.

   

   Parameter	Description
   Data Source Type	OceanBase is selected by default.
   Intelligent Parsing	You can paste a connection string to the field. ODC automatically identifies the string and fills in the corresponding value.
   Type	The type of the database to be connected. ODC supports the following database types: Independent Deployment/Apsara Stack (OceanBase MySQL/OceanBase Oracle): a database instance deployed in your own environment. Public Cloud (OceanBase MySQL Cloud/OceanBase Oracle Cloud): a database instance deployed on Alibaba Cloud. Logical Database (OceanBase MySQL Sharding): a logical databases, which supports only the MySQL mode.
   Endpoint	Host IP: the IP address of the server where the target database is located. Port: the port number of the server where the target database is located. Cluster: the name of the cluster where the target database is located. This parameter is not required for logical databases. Tenant: the name of the tenant in which the target database is located. This parameter is not required for logical databases. **Note ** You can obtain the host name and port number from the details page of the tenant in which the target database is located, such as a tenant created on Alibaba Cloud or in OceanBase Cloud Platform (OCP).
   Database Account	Account: the username of an account created in the tenant. In MySQL mode, this account must have the privilege to access the default database. Password: the password of the account created in the tenant. You can click Test Connection next to the password field to test whether you can connect to the target database. Note An error will be returned if the configurations such as the username, password, and network settings are invalid. You can only connect to a database in the current tenant. Otherwise, a test failure error will be returned. Before saving the settings, you can click Test Connection to test the database connection. If the database username and password are correct, Connection succeeded is displayed. If you use ODC V4.0.0 and later, you can save the connection without setting the database account and password.
   Environment	The type of the environment. Valid values: Development, Test, and Production.

   Note

   For more information about how to configure a data source, see Data source management.

4. Click OK in the lower-right corner of the panel. In the dialog box that appears, enter a connection name.

   

Edit and execute SQL statements

Example: In the SQL window, create a table in the database of the target project.

1. In the SQL window, click Select a database to select the project database.

   

2. In the Switch Database dialog box, select the target database to which the project belongs.

   

3. In the SQL window, edit the following SQL statements to create a table named employee.

   

   CREATE TABLE odc_test.employee (
   emp_no int(120) COMMENT 'Employee ID' NOT NULL,
   birthday date COMMENT 'Birthday' NULL,
   name varchar(120) COMMENT 'Employee name' NULL,
   CONSTRAINT cons_employee_empno PRIMARY KEY (emp_no)) DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_general_ci;
   

4. After the SQL statements are edited, click Run F8 in the toolbar to run all SQL statements in the current SQL window.

   Feature	Description
   Run F8	Runs all SQL statements in the current window.
   Run the current statement F9	Runs all the selected SQL statements or the SQL statement in the line where the pointer is located.
   Abort	Aborts the statement that is being executed.

   

5. On the Results tab, view the execution records and logs.
