I am running jooq 3.10.1
Here is a code snippet with your SELECT statement and its output. As you
will see, the ALTER from the DDL print out do not have the names of the
constraints. But, as you have noted, with your select statement, clearly
the names of the constraints are in the DB system tables. We agree that
the generated java code has the constraint names. *However, the SQL
generated from the DSLContext ddl() method is not capturing the constraint
names.*
******* code *****
List<Schema> schemas = create.meta().getSchemas();
Queries ddl = null;
for (Schema s : schemas) {
if (s.getName().equals("APP")) {
ddl = create.ddl(s);
break;
}
}
for (Query query : ddl.queries()) {
System.out.println(query);
}
String sql = "SELECT
fc.constraintname,ft.tablename,fs.schemaname,fg.descriptor,pc.constraintname,ps.schemaname
FROM sys.sysconstraints fc JOIN sys.sysforeignkeys f ON f.constraintid =
fc.constraintid JOIN sys.sysconglomerates fg ON fg.conglomerateid =
f.conglomerateid JOIN sys.systables ft ON ft.tableid = fg.tableid JOIN
sys.sysschemas fs ON ft.schemaid = fs.schemaid JOIN sys.sysconstraints pc
ON pc.constraintid = f.keyconstraintid JOIN sys.sysschemas ps ON
pc.schemaid = ps.schemaid WHERE cast(fc.type as varchar(32672)) = 'F'";
System.out.println(create.resultQuery(sql).fetch().format());
****** end code ****
