java - 使用 Java Ucanaccess 在 ms-Access 中恢复数据和存储的查询

Question

我有一个 Access 数据库。该数据库包含表和存储的查询。我的目标是使用 Java Ucanaccess(一个 JDBC 连接器)来使用 Access 文件中存储的数据并使用 Jaspersoft 创建报告。

在普通表上查询有效:

Connection conn = ConnexionUtils.getConnection();
        Statement stmt = conn.createStatement();
        String query = "select * from Tab_BOUT";
        ResultSet rs = stmt.executeQuery(query);
        int cpt = 0;
        while ( rs.next() ) {
            int numColumns = rs.getMetaData().getColumnCount();
            for ( int i = 1 ; i <= numColumns ; i++ ) {
                if (i > 1) System.out.print(",  ");
                String columnValue = rs.getString(i);
                System.out.print(columnValue + " " + rs.getMetaData().getColumnName(i));
            }
        }

但问题是我有一些对象在 Access 中使用其他查询。因此，当我尝试调用查询时，它不起作用:

例如，“RQT_STORED”包含:

"SELECT Tab_STO_livraisons.[LIV-TIE_num], Req_BOUT_articles_tous.ART_code_EAN FROM (Tab_STO_livraisons INNER JOIN Tab_STO_détails ON (Tab_STO_livraisons.LIV_num = Tab_STO_détails.[STO-LIV_num]) AND (Tab_STO_livraisons.[LIV-TIE_num] = Tab_STO_détails.[STO-TIE_num])) INNER JOIN Req_BOUT_articles_tous ON Tab_STO_détails.[STO-ART_id] = Req_BOUT_articles_tous.ART_code ORDER BY Tab_STO_livraisons.[LIV-TIE_num], Tab_STO_livraisons.LIV_num, Tab_STO_détails.[STO-ART_id]";

该查询在 Access 中有效，但在 Java 中无效。有人知道如何做到这一点或有更好的解决方案吗？

编辑:以下是一个查询示例:Select * from Req_VENT_lirairie_nouvelles_pages_analysis

access中的真实查询:

SELECT Tab_STO_livraisons.[LIV-TIE_num], Tab_STO_livraisons.LIV_num, Tab_STO_livraisons.LIV_date_livraison, Tab_STO_livraisons.LIV_type_facturation, Tab_STO_détails.[STO-ART_id], Req_BOUT_articles_tous.ART_code_EAN, Tab_STO_détails.STO_nombre, Tab_STO_livraisons.LIV_bdc, Tab_STO_livraisons.LIV_fact_51, Tab_STO_livraisons.LIV_fact_31
FROM (Tab_STO_livraisons INNER JOIN Tab_STO_détails ON (Tab_STO_livraisons.LIV_num = Tab_STO_détails.[STO-LIV_num]) AND (Tab_STO_livraisons.[LIV-TIE_num] = Tab_STO_détails.[STO-TIE_num])) INNER JOIN Req_BOUT_articles_tous ON Tab_STO_détails.[STO-ART_id] = Req_BOUT_articles_tous.ART_code
ORDER BY Tab_STO_livraisons.[LIV-TIE_num], Tab_STO_livraisons.LIV_num, Tab_STO_détails.[STO-ART_id];

和错误消息:

some of my views are querying a MySQL database. Would that be a big problem?

是的。 UCanAccess 可以使用 Access 链接表(指向另一个 Access 数据库中的表的链接表)，但不能使用 ODBC 链接表(指向 ODBC 数据源(如 MySQL 或 SQL Server)中的表的链接表)。
