我收到了一个错误的逗号错误，我似乎无法弄清楚可能导致它的原因，任何帮助都会受到赞赏。
表创建SQL：
CREATE TABLE APPOINTMENTS (APP_ID NUMBER(38) NOT NULL, I_ID NUMBER(38), DATE_TIME VARCHAR2(50), INSPECTION_TYPE VARCHAR2(30), PRICE VARCHAR2(10), HST VARCHAR2(10), TOTAL VARCHAR2(10), CLIENT_NAME VARCHAR2(40), CLIENT_NUMBER VARCHAR2(15), CLIENT_EXT VARCHAR2(10), CLIENT_EMAIL VARCHAR2(50), CLIENT_NAME2 VARCHAR2(40), CLIENT_NUMBER2 VARCHAR2(15), CLIENT_EXT2 VARCHAR2(10), CLIENT_EMAIL2 VARCHAR2(50), ADDRESS VARCHAR2(100), INTERSECTION VARCHAR2(100), CITY VARCHAR2(40), AGENT_ID NUMBER(38), REF_SOURCE VARCHAR2(30), BUILDING_TYPE VARCHAR2(30), SQUARE_FEET NUMBER(38), LIST_PRICE VARCHAR2(15), LOCKBOX VARCHAR2(40), VACANT VARCHAR2(10), NOTES VARCHAR2(255), BILL_TO VARCHAR2(20), PICTURES_REQUESTED VARCHAR2(10), FLAG VARCHAR2(10), APPROVED VARCHAR2(10), BUILDING_PREMIUM VARCHAR2(10), TRAVEL_PREMIUM VARCHAR2(10), SIZE_PREMIUM VARCHAR2(10), HOLIDAY_PREMIUM VARCHAR2(10), MISC_PREMIUM VARCHAR2(10), INSPECTOR_PAID VARCHAR2(10), COMPANY VARCHAR2(10) NOT NULL, SUGGESTED_RETAIL VARCHAR2(10), SUGGESTED_HST VARCHAR2(10), SUGGESTED_TOTAL VARCHAR2(10), PRIMARY KEY (APP_ID));
要插入和执行的Java代码：
dc.query = "INSERT INTO HR.APPOINTMENTS (APP_ID,I_ID, DATE_TIME,INSPECTION_TYPE, PRICE, HST, TOTAL, CLIENT_NAME, CLIENT_NUMBER, CLIENT_EXT, CLIENT_EMAIL,CLIENT_NAME2, "
+ "CLIENT_NUMBER2, CLIENT_EXT2, CLIENT_EMAIL2, ADDRESS, INTERSECTION, CITY, AGENT_ID, REF_SOURCE, BUILDING_TYPE, SQUARE_FEET, LIST_PRICE, LOCKBOX, VACANT,"
+ "NOTES, BILL_TO, PICTURES_REQUESTED, FLAG, APPROVED, BUILDING_PREMIUM, TRAVEL_PREMIUM, SIZE_PREMIUM, HOLIDAY_PREMIUM, MISC_PREMIUM, INSPECTOR_PAID,"
+ "COMPANY, SUGGESTED_RETAIL, SUGGESTED_HST, SUGGESTED_TOTAL)"
+ ""
+ "VALUES (" + hNum + "," + inspector + ",'" + date1 + "','" + inspectionType + "','" + price + "','" + hst + "','" + total + "','" + clientName + "','" + clientNumber + "','"
+ clientExt + "','" + clientEmail + "','" + clientName2 + "','" + clientNumber2 + "','" + clientExt2 + "','" + clientEmail2 + "','" + address + "','" + cMIntersection
+ "','" + city + "'," + hNum2 + ",'" + rSource + "','" + bType + "', 1000 ,'" + listPrice + "','" + lockbox + "','" + vacant + "','" + sInformation + "','" + billTo + "','"
+ pRequested + "','" + flagged + "', 'No', 'No', '0' , '0', '0', '0', '0', 'No','" + company + "','" + suggestedPrice + "','" + suggestedhst + "','" + suggestedTotal + "')";
dc.rset = dc.stmt.executeQuery(dc.query);
答案 0 :(得分：0)
这是一种更通用的方法。您只需要担心下面的Oracle类，并且可能为Factory方法添加一些新条目，因为我只为您定义了一对。
我还在Row类中编写了PreparedStatement的实际执行，但是我从未测试过那么远。让我知道它是否适合您（不要忘记设置您的数据库凭据和东西）...
