我正在使用NamedParameterJdbcTemplate，下面的SQL在Oraclie SQL Developer中运行良好。
选择总和（PRINTEDLICNUM），总和（PRINTEDLICCOPYNUM），来自LICENSEPRINTRECORD的PRIPID，其中PRIPID在（'370212230027855'）GROUP BY PRIPID;
但是这段代码在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类：
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;
}
}
会发生错误，嵌套异常是 java.sql.SQLException：列名无效
下面是详细的跟踪：

NamedParameterJdbcTemplate不支持sum函数吗？ 如果我想使用sum函数，有没有办法实现这个目的？
答案 0 :(得分：0)
java.sql.SQLException：列名无效
例外很清楚。您以错误的方式正确命名了表列名称。
您正在使用rowMapper类，但未定义列名。
更改您的代码如下
recordQueryString.append("SELECT SUM(PRINTEDLICNUM) AS printedLicNum, SUM(PRINTEDLICCOPYNUM) AS printedLicCopyNum, PRIPID from LICENSEPRINTRECORD where PRIPID in (:pripids) GROUP BY PRIPID");
