Question

I would like to create a sp with the next code:

select *
from document
where cod_emp='AAA'
and cod_situation in ('01','02','03');

But I would like (’01’,’02’,’03’) to be a parameter, so I thought something like this would work:

-- sp's call

call sp('"01","02","03"');

-- sp's parameter

in param_txt_cod_situation text;

-- sp's code

set @cons1=
'select *
from document
where cod_emp="AAA" ';

if length(param_txt_cod_situation)>0 then
set @param_txt_cod_situation=param_txt_cod_situation;
set @cons2='and cod_situacion in concat("(",?,")") '
else
set @param_txt_cod_situation=true;
set @cons2='and ?';
end if;

set @cons=concat(
@cons1,
@cons2);

prepare cons from @cons;
execute cons using
@param_txt_cod_situation;
deallocate prepare cons;

But it didn’t work.

Hope you guys can help me.
Thanks very much.

Answer 1

The concat function returns a string in whatever query it is in. You do not want to see if something is in a string but rather a list.

Replace

set @cons2='and cod_situacion in concat("(",?,")") '

with

set @cons2=concat('and cod_situacion in (',?,') ')

and see if that works
