Question

我有一个带有String []和Time []数组列的表。从表中读取工作正常。但是当我试图创建一个记录时......

MyTableRecord r = txJooq.newRecord(MY_TABLE);
r.setId(id);
r.setStringArr("foo", "bar");
r.setTimeArr(LocalTime.of(7, 0), LocalTime.of(10, 0));
r.store();

...我收到以下例外情况。

org.jooq.exception.DataAccessException: SQL [null]; Can't infer the SQL type to use for an instance of [Ljava.lang.String;. Use setObject() with an explicit Types value to specify the type to use.

似乎jOOQ正在生成无效的SQL语句。它创建了

values (
  ...
  ('foo', 'bar'), 
  ...
);

而不是正确的

values (
  ...
  '{"foo", "bar"}', 
  ...
);

我正在使用：

org.jooq：jooq：3.9.1
org.jooq：jooq-codegen：3.9.1
org.postgresql：postgresql：9.4.1212
postgres 9.6

Answer 1

愚蠢的我，我用错误的SQL Dialect配置了jOOQ

new DefaultConfiguration().set(SQLDialect.POSTGRES)

诀窍

无法使用jOOQ
