JOOQ insert into select syntax with specified columns

Question

Can JOOQ do 'insert into select' syntax for specified columns? I run several different tries..

The Tables:

table1 (Expected insert)

1    John      Leo        null         2012/1/28 23:32:23    (Expected insert)

table2

101  John   xxx    xxx     (from table2.col1)
102  xxx    xxx    xxx

table3

101  xxx    Leo    xxx     (from table3.col2)
102  xxx    xxx    xxx

INSERT INTO table1 ( column1, column2 )
SELECT  table2.col1, table3.col2
FROM table2 join table3 t3 on table2.id = table3.id 
where table2.id = 101;

JOOQ code:

create.insertInto(table1, column1, column2 )
      .values( create.select( table2.col1, table3.col2 )
                     .from(table2)
                     .join(table3)
                     .on( table12.id.equal(table3.id) )
                     .where( table2.id.equal(101) ))
     .execute(); //.getSQL();

JOOQ show error message:

The number of values must match the number of fields

Anyone know what problem I make and how I can fix my JOOQ code. thanks, Pay.

Answer 1

You're using the INSERT .. VALUES syntax, instead of the INSERT .. SELECT syntax. Your subquery provides values column1 but you don't provide any value for column2 . What you want to do is described further down in the manual at "Example: INSERT SELECT syntax support". In your case, this would read (jOOQ 2.x syntax, no longer available in jOOQ 3.x):

create.insertInto(table1, 
create.select( table2.col1, table3.col2 )
      .from(table2)
      .join(table3)
      .on( table12.id.equal(table3.id) )
      .where( table2.id.equal(101) ))
      .execute(); //.getSQL();

Or with a custom projection (jOOQ 3.x syntax):

create.insertInto(table1, column1, column2)
      .select(create.select(...))
      .execute();
