Multiples statements where clause with differents values in Sql using JPA - sql

Question

Hi guys I´m doing a native query for my project using JPA, but i don´t know how can I do a type of if and else
in a where clause, my ?0 can be 4 values: 10,20,30 and 40, when ?0 is 10, 20, 30 I should use CI.QTD <=
and when ?0 is 40, the condition should be >= . How can I do this?
Follow my code with one condition:
SELECT rownum AS id,
x.*
FROM (
SELECT ci.text,
ci.lenght
FROM ci_table CI
WHERE (?0 IS NULL OR ci.qtd <= ?0)
GROUP BY ci.text,
ci.lenght
ORDER BY ci.text) x ,
nativequery = true);
ADD THE QUERY AFTER THE ADJUSTMENT:
#Query(value =
"SELECT rownum as ID, X.* FROM (SELECT " +
" CI.PARAM1 " +
" CI.PARAM2, " +
" CI.PARAM3, " +
" CI.PARAM4, " +
" CI.PARAM5" +
" FROM " +
" CM_PARAMS CI " +
" WHERE " +
" (?1 is null or CI.PARAM6 = ?1) " +
" AND (?2 is null or CI.PARAM7 = ?2) " +
" AND (?3 is null or CI.PARAM8 = ?3) " +
" AND (?4 is null or CI.PARAM9 = ?4) " +
" AND (?5 is null or CI.PARAM10 = ?5) " +
" AND (?6 is null or CI.PARAM11 = ?6) " +
" AND (?7 is null or CI.PARAM12 = ?7) " +
" AND (?8 is null or CI.PARAM13 = ?8) " +
" AND (CASE WHEN ?9 >30 THEN CI.PARAM14 > 30 " +
" CASE WHEN ?9 <31 THEN CI.PARAM15 <= ?9 END) = 1 " +
" GROUP BY " +
" CI.PARAM1, " +
" CI.PARAM2, " +
" CI.PARAM3, " +
" CI.PARAM4, " +
" CI.PARAM5" +
" ORDER BY " +
" CI.PARAM1 ASC) X " , nativeQuery = true)

Try:
SELECT rownum AS id,
x.*
FROM (
SELECT ci.text,
ci.lenght
FROM ci_table CI
WHERE (CASE WHEN ?0 IN (10,20,30) THEN CI.QTD <= ?0
WHEN ?0 = 40 THEN CI.QTD > ?0 END) = 1
GROUP BY ci.text,
ci.lenght
ORDER BY ci.text) x ,
nativequery = true);
