"Incompatible data type in operation" 尝试格式化日期时间时出错
"Incompatible data type in operation" Error when trying to format datetime
在 ODI 中，我从 MS SQL 服务器中的 table 获取字段 [datetime]。
来自 MS SQL 的日期时间格式如下：2019-06-26 07:41:00.000.
我需要将其转换为这种格式：26-06-2019 10:41:00 即 DD-MM-YYYY HH:MI:SS 小时 增加 3，然后写入 JSON 文件。
JSON中对应的字段为VARCHAR(string)。
但我收到错误：原因：java.sql.SQLSyntaxErrorException：操作中的数据类型不兼容
我在 ODI 12c 映射属性表达式编辑器中给出了以下表达式：
TO_CHAR(TO_DATE(NVL(SUBSTR(L_MAILITM_EVENTS.EVENT_GMT_DT, 0, INSTR(L_MAILITM_EVENTS.EVENT_GMT_DT, '.')-1),
L_MAILITM_EVENTS.EVENT_GMT_DT ),'YYYY-MM-DD HH24:MI:SS')+ 3/24,
'DD-MM-YYYY HH24:MI:SS')
整个错误：

我哪里错了？
由于目标是文件，所以不是Oracle数据库在做转换，而是ODI Studio或ODI代理的内部HSQL数据库。这里不能使用Oracle函数，可以用HSQL函数代替。以下是可用的函数：http://hsqldb.org/doc/guide/builtinfunctions-chapt.html.
或者，可以在 L_MAILITM_EVENTS 数据存储之后的映射中添加一个表达式，以使用 MS SQL 特定函数对源数据库进行转换。这会将在 MS SQL 上执行的 SELECT 语句更改为直接应用函数。确保将表达式的执行位置更改为源。
