如果結果集與整個行值匹配，如何獲取值？

Question

在這裏我附上我的代碼。當stateVector包含狀態名時，我需要檢查整個行，而不是所有的icd和dicd向量值。我需要怎麼做？

在我的代碼中，它檢查所有向量，一旦statename與任何其他或icdid匹配顯示它可用。

public class LCDEdits 
{ 

@SuppressWarnings("unchecked") 
public String validateICD_CPT(String cptCode, String stateName, String icdCode) throws Exception 
{ 

    /**** Variable Initialization ***/ 
    String lcdRes = null;

    DBConfig db1 = null; 
    ResultSet rs = null; 

    JSONObject JObj = new JSONObject(); 

    try 
    { 
     lcdSql = new StringBuffer(" SELECT cpt.hcpc_code, cpt.lcd_id, statepri.state_abbr, icd.icd10_id, "); 
     lcdSql.append(" dicd.icd10_id_dont FROM lcd_cpt cpt "); 
     lcdSql.append(" LEFT JOIN lcd_statepri statepri ON(cpt.lcd_id = statepri.lcd_id) ");    
     //lcdSql.append(" LEFT JOIN lcd_statesec statesec ON(cpt.lcd_id = statesec.lcd_id) ");

Answer 1

首先，將讀數從數據庫中分離出來並處理數據。

Vector stateVector = null; 

try { 
    Reading data from database 
} catch (the problems) { 
    And handle them 
} finally { 
    close the connection 
} 

然後檢查，如果你有一些數據：

if (stateVector != null { 
    // get the data you want, probably with a loop construct 
}
