我有这样的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;
}
和pQuery是,
public PlanQuery(DataSource dataSource)
{
super();
setDataSource(dataSource);
BQueries bQueries = new BQueries();
setSql(bQueries.getSelectStandardCaseTypeQuery());
declareParameter(new SqlParameter("caseIdNumber",
Types.NUMERIC));
compile();
}
其中getSelectStandardCaseTypeQuery是
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。控件返回到DAO,在DAO中,sysout被打印,但之后我得到了异常,
[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

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DB conenction架构的一切都是正确的指向。但是为什么它在DAO中的finObject中失败了。任何输入?
答案 0 :(得分:0)
看起来你必须使用:
select * from schema.table_name
