要从他人的Web Intelligence报告中提取SQL，可以使用Business Objects的SDK（软件开发工具包）来实现。下面是一个使用Java语言的代码示例：

import com.businessobjects.rebean.wi.DocumentInstance;
import com.businessobjects.rebean.wi.ReportEngine;
import com.businessobjects.rebean.wi.ReportEngines;
import com.businessobjects.rebean.wi.ReportInstance;
import com.businessobjects.rebean.wi.ReportSource;
import com.businessobjects.rebean.wi.Session;
import com.businessobjects.rebean.wi.SessionManager;

public class WebIntelligenceSQLExtractor {
    public static void main(String[] args) {
        String reportPath = "path_to_report.wi";
        String userName = "your_username";
        String password = "your_password";

        // 创建一个会话管理器
        SessionManager sessionManager = SessionManager.createSessionManager();

        // 创建一个会话
        Session session = sessionManager.logon(userName, password);

        try {
            // 获取报告引擎
            ReportEngines reportEngines = (ReportEngines) session.getService("ReportEngines");
            ReportEngine reportEngine = reportEngines.getService(ReportEngines.WI_REPORT_ENGINE);

            // 加载报告
            ReportSource reportSource = reportEngine.createReportSource(reportPath);
            DocumentInstance documentInstance = reportSource.getReportInstance().getDocumentInstance();
            
            // 提取SQL
            String sql = documentInstance.getSQL().getText();

            System.out.println("Extracted SQL: " + sql);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭会话
            session.logoff();
        }
    }
}

请注意，上述代码示例仅提供了从Web Intelligence报告中提取SQL的基本框架。您需要根据自己的具体需求进行适当的更改和调整。
