Jooq & R2DBC execute DDL
Yes, both jOOQ and R2DBC can execute DDL (Data Definition Language) statements.
jOOQ is a SQL-centric library that allows you to write type-safe SQL queries in Java. It supports executing all types of SQL statements, including DDL statements. To execute a DDL statement with jOOQ, you can use the DSLContext.execute()
method, which takes a string containing the SQL statement as an argument.
Here’s an example of how you can use jOOQ to execute a DDL statement to create a new table:
javaDSLContext context = DSL.using(connection, SQLDialect.MYSQL); context.execute("CREATE TABLE customers (id INT PRIMARY KEY, name VARCHAR(50));");
On the other hand, R2DBC is a reactive database driver that allows you to interact with databases using a reactive programming model. It also supports executing DDL statements. To execute a DDL statement with R2DBC, you can use the Connection.createStatement()
method, which returns a Statement
object that you can use to execute the SQL statement.
Here’s an example of how you can use R2DBC to execute a DDL statement to create a new table:
javaConnection connection = DatabaseClient.create() .execute("CREATE TABLE customers (id INT PRIMARY KEY, name VARCHAR(50));") .map(result -> result.getRowsUpdated()) .then(Mono.from(connectionMono)) .block(); connection.close();
In this example, we use the DatabaseClient
to execute the DDL statement, and then we use the Mono.from()
method to wrap the connection into a Mono so that we can close it when we’re done.
