Problem with Mysql result set, if there is 0 row on main query produce result from sub-query

Question

I have a query that checks the value of some case from DB and finds the rank in witch that value resides in table BOD :

        SELECT DISTINCT bod_bod, (SELECT REPLACE(predf_VPS,'.','') as vps FROM PREDMETIFView WHERE
     predf_nas_br=?) as vps_baza FROM BOD WHERE (SELECT REPLACE(predf_VPS,'.','') as vps
 FROM PREDMETIFView WHERE predf_nas_br=?) BETWEEN bod_od AND bod_do ORDER BY bod_bod ASC
                  LIMIT 1

Table BOD is:

| bod_id | bod_od    | bod_do    | bod_bod | bod_dodan           |
| ------ | --------- | --------- | ------- | ------------------- |
| 0      | 0.00      | 2500.00   | 25      | 0000-00-00 00:00:00 |
| 1      | 2500.01   | 5000.00   | 50      | 0000-00-00 00:00:00 |
| 2      | 5000.01   | 10000.00  | 75      | 0000-00-00 00:00:00 |
| 3      | 10000.01  | 100000.00 | 100     | 2020-04-10 13:06:53 |
| 4      | 100000.01 | 250000.00 | 250     | 0000-00-00 00:00:00 |
| 5      | 250000.01 | 500000.00 | 500     | 2020-04-08 23:04:30 |

Current SQL for the sub-query value 11899 from PREDMETIFView table select gives me result:

bod_bod     vps_baza    
100     11899

because number 11899 is between 10000.01 and 100000.00 .

I later do some calculations with that number in PHP.

But here is the problem: When the number is bigger then 500000.00, result set from query is 0 rows (because there is no rank that matches). But I still need that number vps_baza to do calculations in PHP.

So is there a way to say if there is no ranked matches that it still produces one result row (without altering table BOD) of for example for vps_baza 511899 value:

bod_bod     vps_baza    
null    511899

MySQL version is 5.6

I have made an DBfiddle:

If you change value on line 98 from 511899 to for example 899 , i get the row, but bigger values then 500000 it fails.

Answer 1

You can use left join :

select x.vps_baza, . . .
from (select 11899 as vps_baza) x left join
     bods b
     on x.vps.baza between b.bod_od and b.bod_do;

Note: This answer is based on your question and sample data. It is quite unclear to me what the query has to do with either of those.
