Together with Gudu Software, we have created an Open Source SQL 2 jOOQ parser that takes native SQL statements as input and generates jOOQ code as output.
Gudu Software Ltd has been selling enterprise quality SQL software to hundreds of customers to help them migrate from one database to another using the General SQL Parser. Now you can take advantage of their knowledge to parse your SQL statements and transform them directly into jOOQ statements using a free trial version of SQL 2 jOOQ!
It's as simple as this!
- Create a JDBC connection
- Create a new SQL2jOOQ converter object
- Convert your SQL code
- Get the result
See it in action:
package gudusoft.sql2jooq.readme;
import gudusoft.gsqlparser.EDbVendor;
import gudusoft.gsqlparser.sql2jooq.SQL2jOOQ;
import gudusoft.gsqlparser.sql2jooq.db.DatabaseMetaData;
import gudusoft.gsqlparser.sql2jooq.tool.DatabaseMetaUtil;
import java.sql.Connection;
import java.sql.DriverManager;
public class Test {
public static void main(String[] args) throws Exception {
// 1. Create a JDBC connection
// ---------------------------
String userName = "root";
String password = "";
String url = "jdbc:mysql://localhost:3306/guestbook";
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection(url, userName, password);
// 2. Create a new SQL2jOOQ converter object
// -----------------------------------------
DatabaseMetaData metaData = DatabaseMetaUtil
.getDataBaseMetaData(conn, "guestbook");
SQL2jOOQ convert = new SQL2jOOQ(metaData,
EDbVendor.dbvmysql,
"select first_name, last_name from actor where actor_id = 1;");
// 3. Convert your SQL code
// ------------------------
convert.convert();
if (convert.getErrorMessage() != null) {
System.err.println(convert.getErrorMessage());
System.exit(-1);
}
// 4. Get the result
// -----------------
System.out.println(convert.getConvertResult());
}
}
If all goes well, the above program yields:
DSLContext create = DSL.using(conn, SQLDialect.MYSQL);
Result<Record2<String, String>> result = create.select( Actor.ACTOR.FIRST_NAME, Actor.ACTOR.LAST_NAME )
.from( Actor.ACTOR )
.where( Actor.ACTOR.ACTOR_ID.eq( DSL.inline( UShort.valueOf( 1 ) ) ) ).fetch( );
SQL 2 jOOQ is a joint venture by Gudu Software Limited and Data Geekery GmbH. We will ship, test and maintain this awesome new addition with our own deliverables. So far, SQL 2 jOOQ supports the MySQL and PostgreSQL dialects and it is in an alpha stadium. Please, community, provide as much feedback as possible to make this great tool rock even more!
Please take note of the fact that the sql2jooq library is Open Source, but it depends on the commercial gsp.jar parser, whose trial licensing terms can be seen here:
https://github.com/sqlparser/sql2jooq/blob/master/sql2jooq/LICENSE-GSQLPARSER.txt
For more information about the General SQL Parser, please refer to the product blog.
Please report any issues, ideas, wishes to the jOOQ user group or the sql2jooq GitHub project.
