我有一个这样的DAO，

public String getCaseTypeById(String caseIdNumber) {
        String caseType = null;

        SqlQuery caseQuery = 
            new PQuery(getDataSource());
        System.out.println("caseIdNumber   --"+caseIdNumber);
        caseType = (String)caseQuery.findObject(caseIdNumber);
        System.out.println("before return");

        return caseType;
    }

并且 pQuery 是

public PlanQuery(DataSource dataSource)
{
    super();
    setDataSource(dataSource);
    BQueries bQueries = new BQueries();

    setSql(bQueries.getSelectStandardCaseTypeQuery());
    declareParameter(new SqlParameter("caseIdNumber",
            Types.NUMERIC));
    compile();
}

getSelectStandardCaseTypeQuery 在哪里，

public String getSelectStandardCaseTypeQuery() {

String selectCaseTypeByCaseId = null;

        selectCaseTypeByCaseId = 
            " SELECT ct.C_CODE as c_code " + 
            "  FROM  " + getSchemaName() + ".csummary cs, " + 
                getSchemaName() + ".ctype ct " +
            "   WHERE cs.c_number = ? " + 
            "   AND UPPER(ct.C_DESC_TEXT) = UPPER(cs.C_TYPE) ";

    return selectCaseTypeByCaseId;
}

现在上面的返回工作正常。控制返回到 DAO 并在 DAO 中打印 sysout 但之后我得到异常，

[从 gpt.csummary cs 中选择 ct.C_CODE 作为 c_type_code，gpt.ctype ct WHERE cs.c_number = ? AND UPPER(ct.C_DESC_TEXT) = UPPER(cs.C_TYPE) ]; 嵌套异常是 java.sql.SQLException: ORA-00942: 表或视图不存在

包装异常：org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; 错误的 SQL 语法 [ SELECT ct.C_CODE as c_type_code FROM gpt.csummary cs, gpt.ctype ct WHERE cs.c_number = ? AND UPPER(ct.C_DESC_TEXT) = UPPER(cs.C_TYPE) ]; 嵌套异常是 java.sql.SQLException: ORA-00942: 表或视图不存在。

但是当我在蟾蜍中执行相同的操作时，一切正常。我看到那个数据库连接模式一切都是正确的。但是为什么在DAO中的finObject中会失败。任何输入？

看起来你必须使用：

select * from schema.table_name
