在 JOOQ 中使用 PL/SQL 函数
Use PL/SQL Function in JOOQ
我需要调用 PL/SQL 函数，return 一个 table 形式的对象类型。
基本上像：
select * from TABLE(get_druck_variablen(123456);
到目前为止，我在 JOOQ 中使用本机查询并且有效：
final Result<Record> result = create.fetch("select * from TABLE(myschema.get_druck_variablen(" + id + "))");
但我想在 JOOQ 中正确地完成它。
1) 我来到这里：
final GetDruckVariablen getDruckVariablen = new GetDruckVariablen();
getDruckVariablen.setPId(id);
getDruckVariablen.execute();
但后来我遇到了这个异常
Method threw 'java.lang.NullPointerException' exception. Cannot evaluate de.company.jooq.routines.GetDruckVariablen.toString()
2) 然后我尝试了这个：
final TabOtDruckVariablenRecord getDruckVariablen = Routines.getDruckVariablen(create.configuration(), id).;
然后我得到了这个异常：
Caused by: org.springframework.jdbc.BadSqlGrammarException: jOOQ; bad SQL grammar [select "array_table"."COLUMN_VALUE" from table ("MYSCHEMA"."GET_DRUCK_VARIABLEN"(?)) "array_table"]; nested exception is java.sql.SQLSyntaxErrorException: ORA-00904: "array_table"."COLUMN_VALUE": ungültiger Bezeichner
有关信息，这是我的 PL/SQL 函数：
create or replace FUNCTION get_druck_variablen(p_id IN vk_types.t_id) RETURN myschema.tab_ot_druck_variablen
PIPELINED
IS
....
BEGIN
END get_druck_variablen;
对象类型：
create or replace TYPE ot_druck_variablen FORCE AS OBJECT
(
ob_id NUMBER(9, 0),
ob_txv_name VARCHAR2(100),
ob_txv_wert VARCHAR2(2000)
)
Table类型：
create or replace TYPE tab_ot_druck_variablen AS TABLE OF myschema.ot_druck_variablen
我真的很希望有人能帮助我。
提前致谢。
此致
伊万
为以下问题的答案添加了 Stake 跟踪：
final GetDruckVariablen getDruckVariablen = new GetDruckVariablen();
getDruckVariablen.setPId(id);
getDruckVariablen.execute(dslContext.configuration());

我怀疑您 运行 遇到了错误（现在可能已修复）。一旦我知道您使用的是哪个 jOOQ 版本，我将用 link 更新我对相关 GitHub 问题的回答。
关于 1) 和 NullPointerException
您尝试 1 中出现 NPE 的可能原因：
final GetDruckVariablen getDruckVariablen = new GetDruckVariablen();
getDruckVariablen.setPId(id);
getDruckVariablen.execute();
... 可能是因为您没有将 Configuration 传递给 execute() 方法。 Configuration less 方法假定您的例程调用以前是 "attached" 到 Configuration。但最好明确地传递它：
getDruckVariablen.execute(configuration);
关于您的本机查询用法的旁注：
你肯定知道这一点，但我不得不为未来的读者提及它。您对 jOOQ plain SQL API 的使用暴露了一定的 SQL 注入风险，此外还会给游标缓存带来压力：
final Result<Record> result = create.fetch(
"select * from TABLE(myschema.get_druck_variablen(" + id + "))");
最好使用绑定变量，这对于普通 SQL 也是完全可能的：
final Result<Record> result = create.fetch(
"select * from TABLE(myschema.get_druck_variablen(?))", id);
