I have a problem with "types"

Warning: pg_exec(): Query failed: ERROR: UNION types text and integer cannot be matched in /var/www/site/admin/php/db_pgsql.inc on line 75
Database error: Invalid SQL: SELECT * FROM doc_reference WHERE doc_ref_cod = -2 union all select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22
PostgreSQL Error: 1 (ERROR: UNION types text and integer cannot be matched)
Session halted.


Code:
union all select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22


"UNION types text and integer cannot be matched"

Since I solve it?

Best Regards

PostgreSql is bit*hing about data types ...

Try to substitute some numbers with version(), like:

Code:

union all select 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,version()


You must find (via trial and error) exactly what columns need which data type. And of course, there is casting possibility:

,14,15,16::text,17,18
