Question

I’m trying to get the following SQL statement to work:

UPDATE myschema.tableA update_tableA    SET field_id =     ( SELECT src.field_id           FROM myschema.srcTable src          INNER JOIN myschema.tableB tableB ON              update_tableA.id = tableB.id              AND SDO_ANYINTERACT( tableB.shape, src.shape ) = 'TRUE' ); 

When I run this statement, I get the following error:

ORA-00904: 'UPDATE_TABLEA'.'ID': invalid identifier 

Can I not use a variable scoped outside of the nested select within the nested select? Any thoughts?

P.S. The identifier is indeed valid in the database table. The problem appears to be scope, but I want to make sure that is indeed an issue.

I don’t believe you can JOIN on a column (i.e. use it in the ON clause) that’s not in one of the tables being joined. Additional predicates need to be in a WHERE clause.

Try this:

UPDATE myschema.tableA update_tableA    SET field_id =     ( SELECT src.field_id           FROM myschema.srcTable src          INNER JOIN myschema.tableB tableB ON             SDO_ANYINTERACT( tableB.shape, src.shape ) = 'TRUE'         WHERE update_tableA.id = tableB.id     );
