Follow-up Operations

After logging in to a TaurusDB instance through DAS, you can manage your databases.

1. Create a database.

   After logging in to a TaurusDB instance, click Create Database on the home page, enter database information, and click OK.

4. Log in to the database as the created user and write data into the database.

   On the DAS development tool page, add a database login as user user. Click Log In in the Operation column to log in to the TaurusDB instance.

   Figure 14 Adding a login as user
   

   In the row containing the test database, click Query SQL Statements in the Operation column. The SQL execution window is displayed.

   Figure 15 Accessing the SQL execution window
   

   Run the following SQL statement in the SQL input box to query data in table1:

   SELECT * FROM table1;

   Figure 16 Viewing table data
   

   There is no data in table1.

   Run the following SQL statements to write several data records to table1:

   insert into table1(id, name, age) values(1, 'sam', 30);

   insert into table1(id, name, age) values(2, 'cidy', 25);

   insert into table1(id, name, age) values(3, 'lily', 27);

   Figure 17 Writing data to the table
   

   Data has been written into the table.

   Run the following SQL statement again to check whether there is data in table1:

   SELECT * FROM table1;
