Tyvärr ger Oracle JDBC-drivrutinen inte åtkomst till PL/SQL RECORD
typ, varken för IN
inte heller för OUT
parametrar.
Lösning för ett enda proceduranrop:
Men du kan kringgå denna begränsning genom att använda ett anonymt PL/SQL-block i JDBC (eller Spring JDBC) direkt:
DECLARE
rec MY_PACKAGE.MY_RECORD;
BEGIN
-- Replace these by your actual record attributes:
rec.first_name := ?;
rec.last_name := ?;
...
p_insertclient(rec);
END;
Detta fungerar alldeles utmärkt för ett enda proceduranrop.
En solid lösning för många av dessa samtal:
Om du gör ovanstående ganska ofta är det värt att generera stubbar som producerar de anonyma PL/SQL-strängarna automatiskt, snarare än att skriva dem manuellt hela tiden. Du kan automatiskt upptäcka alla PL/SQL RECORD
skriver in ditt schema med följande fråga:
SELECT
x.TYPE_OWNER, x.TYPE_NAME, x.TYPE_SUBNAME, a.ARGUMENT_NAME ATTR_NAME,
a.SEQUENCE ATTR_NO, a.TYPE_OWNER ATTR_TYPE_OWNER,
nvl2(a.TYPE_SUBNAME, a.TYPE_NAME, NULL) package_name,
COALESCE(a.TYPE_SUBNAME, a.TYPE_NAME, a.DATA_TYPE) ATTR_TYPE_NAME,
a.DATA_LENGTH LENGTH, a.DATA_PRECISION PRECISION, a.DATA_SCALE SCALE
FROM SYS.ALL_ARGUMENTS a
JOIN (
SELECT
a.TYPE_OWNER, a.TYPE_NAME, a.TYPE_SUBNAME,
MIN(a.OWNER) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) OWNER,
MIN(a.PACKAGE_NAME) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) PACKAGE_NAME,
MIN(a.SUBPROGRAM_ID) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) SUBPROGRAM_ID,
MIN(a.SEQUENCE) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) SEQUENCE,
MIN(next_sibling) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) next_sibling,
MIN(a.DATA_LEVEL) KEEP (DENSE_RANK FIRST ORDER BY a.OWNER ASC, a.PACKAGE_NAME ASC, a.SUBPROGRAM_ID ASC, a.SEQUENCE ASC) DATA_LEVEL
FROM (
SELECT
lead(a.SEQUENCE, 1, a.SEQUENCE) OVER (
PARTITION BY a.OWNER, a.PACKAGE_NAME, a.SUBPROGRAM_ID, a.DATA_LEVEL
ORDER BY a.SEQUENCE ASC
) next_sibling,
a.TYPE_OWNER, a.TYPE_NAME, a.TYPE_SUBNAME, a.OWNER, a.PACKAGE_NAME,
a.SUBPROGRAM_ID, a.SEQUENCE, a.DATA_LEVEL, a.DATA_TYPE
FROM SYS.ALL_ARGUMENTS a
WHERE a.OWNER IN ('MY_SCHEMA') -- Possibly replace schema here
) a
WHERE (a.TYPE_OWNER IN ('MY_SCHEMA') -- Possibly replace schema here
AND a.OWNER IN ('MY_SCHEMA') -- Possibly replace schema here
AND a.DATA_TYPE = 'PL/SQL RECORD')
GROUP BY a.TYPE_OWNER, a.TYPE_NAME, a.TYPE_SUBNAME
) x
ON ((a.OWNER, a.PACKAGE_NAME, a.SUBPROGRAM_ID) = ((x.OWNER, x.PACKAGE_NAME, x.SUBPROGRAM_ID))
AND a.SEQUENCE BETWEEN x.SEQUENCE AND next_sibling
AND a.DATA_LEVEL = (x.DATA_LEVEL + 1))
ORDER BY x.TYPE_OWNER ASC, x.TYPE_NAME ASC, x.TYPE_SUBNAME ASC, a.SEQUENCE ASC
