使用存储过程执行时executeUpdate不起作用

如何解决使用存储过程执行时executeUpdate不起作用

executeUpdate返回1，但是没有将值插入表中。 “ CR_SAVEHBCRPERFORMA”是插入值的过程。输出参数在执行完否则返回0后返回1，在这里返回0 ..（某些代码缺少bcoz的长度 ）

    Connection con = null;
    CallableStatement cstmt1 = null;
    DataSource ds = null;
    ResultSet rs = null;
    try {
       
        String REGNO = request.getParameter("regNo");
        String CENTERNAME = request.getParameter("center");
        String DIAGNOSISDATE = request.getParameter("firstDiag");
        RccDataSources rccDS = new RccDataSources();
        ds = rccDS.getOncoLiveDS();
        con = ds.getConnection();
        cstmt1 = con.prepareCall("{CALL CR_SAVEHBCRPERFORMA(?,?,?)}");
        cstmt1.setString(1,REGNO);
        cstmt1.setString(2,CENTERNAME);
        cstmt1.setString(3,DIAGNOSISDATE);
        cstmt1.setString(4,SOURCEREG);
        cstmt1.setString(5,SOURCEREF);
        cstmt1.setString(6,LABNO); 
        cstmt1.setString(7,FIRSTSEENDATE);
        cstmt1.setString(8,EDUCATION);
        cstmt1.setString(28,TREATMENTRITYPE);
        cstmt1.setString(29,STATUSFOLLOWUP);
        cstmt1.setString(30,DISEASESTATUS);
        cstmt1.setString(31,REMARK);
        cstmt1.registerOutParameter(32,Types.INTEGER);
        cstmt1.executeUpdate();
        int x = cstmt1.getInt(32);
  
    } 
}

}

解决方法

使用

cstmt1.execute();

例如

        stmt.setString(1,doc_number);
        stmt.setString(2,doc_type);
        stmt.setString(3,line_number);
        stmt.registerOutParameter(4,oracle.jdbc.OracleTypes.CURSOR);
        
        stmt.execute();
        cursor = stmt.getCursor(4);
