Question

我有一个调用Oracle数据库包函数所需的Grails应用程序。

该函数的返回值是RECORD Oracle数据类型。

RECORD映射到的Java Oracle数据类型是什么？

我找到了this page，但是，我要么失明，要么没有我需要的信息。

示例代码：

包类型声明

TYPE subjectDuration IS RECORD (
  min_duration PLS_INTEGER,
  max_duration PLS_INTEGER
);

功能

FUNCTION getSubjectDuration(
  subject_code IN PACKGE.SUBJ_CODE%type,
  course_number IN PACKGE.CRSE_NUMB%type,
  term_code IN PACKGE.EFF_TERM%type
)
RETURN subjectDuration
IS
  record_rowid ROWID;
  subject_duration subjectDuration;
BEGIN
  ...
  /*function code */

  RETURN(subject_duration);
END;

调用上述函数的Grails代码

String packageCheck = "BEGIN packge.getSubjectDuration(:subjectCode, :courseNumber, :termCode); END; "

sql.call(packageCheck, [subjectCode: subjectCode, courseNumber: courseNumber, termCode: termCode],
    // OracleTypes.OTHER is the wrong type. I need the correct type for RECORD, which doesn't exist in OracleTypes.
    Sql.resultSet(OracleTypes.OTHER)) { cursorResults ->         
    if (cursorResults.next()) {
        def result = cursorResults.getAt(0)
        log.debug(result)
    }
}

我的解决方案如下：

import oracle.jdbc.driver.OracleTypes
...
try {
    String packageCheck = "BEGIN csu.swrtcbs.getSubjectDuration(?, ?, ?, ?, ?); END; "

    sql.call(packageCheck, [subjectCode, courseNumber, termCode, Sql.out(OracleTypes.NUMBER), Sql.out(OracleTypes.NUMBER)]) { minDur, maxDur ->

        //log.debug("From Banner: Min duration: ${minDur}, Max duration: ${maxDur}")
        minDuration = (minDur == null) ? 1 : ((java.math.BigDecimal) minDur).toString()
        maxDuration = (maxDur == null) ? null : ((java.math.BigDecimal) maxDur).toString()
    }

    // Do something with the output: minDuration and maxDuration

} catch (Exception e) {
    log.error("Something failed.", e)
}

输出在sql.call中指定为Sql.out()并指定OracleType。
