INSERT VALUES Statement in Confluent Cloud for Apache Flink¶
Confluent Cloud for Apache Flink® enables inserting data directly into a Flink SQL table.
Syntax¶
[EXECUTE] INSERT { INTO | OVERWRITE } [catalog_name.][database_name.]table_name VALUES
(value1 [, value2, ...])
[, (value3 [, value4, ...])]
Description¶
Insert data into a table.
Use the INSERT VALUES statement to insert one or more rows into a table by specifying the value for each column.
For example, the following statement inserts a single row into a table named
orders that has four columns.
INSERT INTO orders VALUES (1, 1001, '2023-02-24', 50.0);
You can insert multiple rows by using a comma-separated list of values.
INSERT INTO orders VALUES
(1, 1001, '2023-02-24', 50.0),
(2, 1002, '2023-02-25', 60.0),
(3, 1003, '2023-02-26', 70.0);
Example¶
In the Flink SQL shell or in a Cloud Console workspace, run the following commands to see an example of the INSERT VALUES statement.
Create a users table.
-- Create a users table. CREATE TABLE users ( user_id STRING, registertime BIGINT, gender STRING, regionid STRING );
Insert rows into the
userstable.-- Populate the table with mock users data. INSERT INTO users VALUES ('Thomas A. Anderson', 1677260724, 'male', 'Region_4'), ('Trinity', 1677260733, 'female', 'Region_4'), ('Morpheus', 1677260742, 'male', 'Region_8'), ('Dozer', 1677260823, 'male', 'Region_1'), ('Agent Smith', 1677260955, 'male', 'Region_0'), ('Persephone', 1677260901, 'female', 'Region_2'), ('Niobe', 1677260921, 'female', 'Region_3'), ('Zee', 1677260922, 'female', 'Region_5');
Inspect the inserted rows.
SELECT * FROM users;
Your output should resemble:
user_id registertime gender regionid Thomas A. Anderson 1677260724 male Region_4 Trinity 1677260733 female Region_4 Morpheus 1677260742 male Region_8 Dozer 1677260823 male Region_1 Agent Smith 1677260955 male Region_0 Persephone 1677260901 female Region_2 Niobe 1677260921 female Region_3 Zee 1677260922 female Region_5
