当我尝试执行此JDBC查询时,为什么我获得此"SQLSyntaxErrorException:ORA-00933:SQL命令未正确结束"？

Question

尝试在Java应用程序中实现简单的JDBC查询时遇到了一些问题.

所以我有以下查询:

SELECT   D.*
FROM   coda_tx c, documenti_tx d
WHERE   C.FK_TIPO_DOC = 99
        AND C.FK_STATO = 1
        AND C.FK_PIVA_MITTENTE = '05779711000'
        AND C.PK_CODA = D.PFK_CODA
        AND C.CANALE='STA'

如果我将它运行到Oracle SQL Developer中,它运行良好,我获得了2条记录.

所以我必须将此查询实现到我的应用程序的DAO类中,其中我定义了以下方法:

public void getListaFatturePDF(String partitaIva) {
    System.out.println("INTO ottieniListaFatturePDF()");

    Blob blobPdf;
    String sql;

    StringBuffer sb = new StringBuffer();
    sb.append("SELECT D.*");
    sb.append("FROM coda_tx c, documenti_tx d");
    sb.append("WHERE C.FK_TIPO_DOC = 99");
    sb.append("AND C.FK_STATO = 1");
    sb.append("AND C.PK_CODA = D.PFK_CODA");
    sb.append("AND C.CANALE='STA'");
    sb.append("AND C.FK_PIVA_MITTENTE = '");
    sb.append(partitaIva);
    sb.append("';");

    sql = sb.toString();

    try {
        statment = connection.createStatement();
        ResultSet rs = statment.executeQuery(sql);
        System.out.println("ResultSet obtained");
    } catch (SQLException e) {
        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    }

}

问题是当我尝试执行前面的方法时抛出以下SQLException:

java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended

    at DAO.FatturaDAO.getListaFatturePDF(FatturaDAO.java:43)
    at mainPkg.Main.main(Main.java:74)

为什么？我认为这可能是SQL语法中的错误但我不确定(因为如果我执行查询到Oracle SQL Developer它工作正常)我缺少什么？我该如何解决？

executeQuery() 执行时自动在语句中添加分号.

将行更改sb.append("';");为sb.append("'");.

此外,您还需要在每行的末尾或开头添加空格,否则您的语句无效.
