Flink SQL

As Flink SQL is used in SQL Stream Builder, you can execute the supported Flink DDL, DML and query statements directly from the SQL window in Streaming SQL Console.

Flink DDL
Flink SQL supports Data Definition Language (DDL) statements to create, modify and remove objects within a data structure.
Flink DML
Flink SQL supports Data Manipulation Language (DML) statements to manipulate the data itself with adding, deleting or modifying.
Flink Queries
Flink SQL supports querying data with SELECT statements and using different types of operations.
Other supported statements
Beside the supported DDL, DML and SELECT, the supported statements also include DESCRIBE, SHOW and SET that you can use in SQL Stream Builder.
Data Types
The logical type of a value to declare input and output types of operations in a table ecosystem is described by data types. Flink support a set of pre-defined data types that can be also used in SQL Stream Builder (SSB).
Dynamic SQL Hints
SQL hints are supported for SQL Stream Builder (SSB) that allows you to use the dynamic table options. With the dynamic table options, you can alter any option of a table on a query level.
SQL Examples
You can use the SQL examples for frequently used functions, syntax and techniques in SQL Stream Builder (SSB). SSB uses Calcite Compatible SQL, but to include the functionality of Flink you need to customize certain SQL commands.
