Sub query with dynamic parameters
Posted by: Allan Andrade ()

I'm needing to create a query with a subselect composed of dynamic fields, ie values that are in the selection.
, val_fk
, cmb.*
, (select cmb.campo_des from cmb.tabela where cmb.campo_id = d.val_new)
FROM w_log_evento as e
left join w_log_detalhe as d on d.fk_log_evento = e.cod_log
left join w_campos as c on c.nome_campo = d.campo and c.fk_pagina = e.fk_pagina
left join w_campos_cfg_combo as cmb on cmb.fk_campo = (select c3.cod_campo from w_campos as c3 where c3.fk_pagina = e.fk_pagina and c3.nome_campo = d.campo)

I have a table with LOG (w_log_evento), which has details (w_log_detalhe), which in turn has fields of type COMBO (select option in html), which is linked (in one to one relationship) with the configuration table combos (w_campos_cfg_combo).

It works fine without the sub-select, and returns the following:
label_campo, "val_fk", "tabela", "campo_des", "campo_id"
Rubrica, "51", "st_proj_rubrica","des_rubrica", "cod_proj_rubrica"
Fornecedor, "103650", "sv_pes_juridica","completo", "fk_pessoa"

The idea is that it mount a sub-query with the field value table, and campo_des campo_id and bring the return for each line.

Can anyone help?

Grateful to all!
