INSERT Statements
Data can be inserted into sink tables in various ways. You can use the INSERT clause to insert the query result into a table, or you can use the VALUE clause to insert data into tables directly from SQL.
You can use the INSERT
clause with different source tables, or the
VALUES
clause. The following examples show how to use
INSERT
and VALUES
at the same time:
tableEnv.sqlUpdate("CREATE TABLE source_table (c1 STRING) WITH (...)");
tableEnv.sqlUpdate("CREATE TABLE sink_table (c1 STRING) WITH (...)");
tableEnv.sqlUpdate("INSERT INTO source_table VALUES ('foo')");
Table elements = tableEnv.fromDataStream(env.fromElements("bar"));
tableEnv.sqlUpdate("INSERT INTO source_table SELECT f0 from " + elements);
tableEnv.sqlUpdate("INSERT INTO sink_table SELECT * from source_table");
Table table = tableEnv.sqlQuery("SELECT * FROM sink_table");
tableEnv.toAppendStream(table, Row.class).printToErr();
For more information about INSERT
statements, see the Apache Flink documentation.
