NamedParameterJdbcTemplate不支持SUM（）嗎？

Question

我使用的是NamedParameterJdbcTemplate，下面的SQL在Oraclie SQL Developer中運行良好。

從LICENSEPRINTRECORD中選擇sum（PRINTEDLICNUM），sum（PRINTEDLICCOPYNUM），PRIPID，其中（'370212230027855'）GROUP BY PRIPID中的PRIPID；

但是此代碼在NamedParameterJdbcTemplate中不起作用

Map namedParameters = Collections.singletonMap("pripids", pripIds);
StringBuffer recordQueryString = new StringBuffer();
recordQueryString.append("SELECT SUM(PRINTEDLICNUM), SUM(PRINTEDLICCOPYNUM), PRIPID from LICENSEPRINTRECORD where PRIPID in (:pripids) GROUP BY PRIPID");
List<PreviousPrintRecords> records = template.query(recordQueryString.toString(), namedParameters, new RowMapper<PreviousPrintRecords>());

下面是我的RowMapper類：

public class PreviousPrintRecords implements Serializable{

/**
 * 
 */
private static final long serialVersionUID = -3763072257141955974L;
private int printedLicNum;
private int printedLicCopyNum;
private String pripId;  

public PreviousPrintRecords() {
    super();
}

public PreviousPrintRecords(int printedLicNum, int printedLicCopyNum, String pripId) {
    super();
    this.printedLicNum = printedLicNum;
    this.setPrintedLicCopyNum(printedLicCopyNum);
    this.pripId = pripId;
}

public int getPrintedLicNum() {
    return printedLicNum;
}

public void setPrintedLicNum(int printedLicNum) {
    this.printedLicNum = printedLicNum;
}

public String getPripId() {
    return pripId;
}

public void setPripId(String pripId) {
    this.pripId = pripId;
}

public int getPrintedLicCopyNum() {
    return printedLicCopyNum;
}

public void setPrintedLicCopyNum(int printedLicCopyNum) {
    this.printedLicCopyNum = printedLicCopyNum;
}

}

它將發生錯誤，嵌套異常是java.sql.SQLException：無效的列名

下面是詳細的跟蹤：

NamedParameterJdbcTemplate不支持sum函數嗎？ 如果我想使用sum函數，有什么方法可以實現？

Answer 1

java.sql.SQLException：無效的列名

足夠明顯的例外。 您用錯誤的方式正確命名了表列名稱。

您正在使用rowMapper類，但未定義列名稱。

如下更改代碼

recordQueryString.append("SELECT SUM(PRINTEDLICNUM) AS printedLicNum, SUM(PRINTEDLICCOPYNUM) AS printedLicCopyNum, PRIPID from LICENSEPRINTRECORD where PRIPID in (:pripids) GROUP BY PRIPID");
