NamedParameterJdbcTemplate NOT SUPPORT SUM（）？

标签： java spring jdbctemplate

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");
