Oracle 存储过程分页 + Sqlsugar调用

一、Oracle 存储过程分页

create PROCEDURE GetPatientVisitData(
    p_HospId IN VARCHAR2, -- 院区编码
    p_strDate IN VARCHAR2, -- 开始日期
    p_endDate IN VARCHAR2, -- 结束日期
    p_page_size IN NUMBER, -- 每页记录数
    p_page_number IN NUMBER, -- 当前页码
    p_result OUT SYS_REFCURSOR, -- 结果集
    p_total_count OUT NUMBER   -- 总记录数
) AS
BEGIN
    -- 计算总记录数
    SELECT COUNT(*)
    INTO p_total_count
    FROM (
         SELECT * FROM 表名
    );
    -- 分页查询数据
    OPEN p_result FOR
    -- 你的查询语句
    SELECT 字段1，字段2，ROW_NUMBER() OVER (ORDER BY 排序字段) AS rn FROM 表名 AS A
    --分页
    WHERE A.rn BETWEEN (p_page_number - 1) * p_page_size + 1 AND p_page_number * p_page_size ;
END GetPatientVisitData;
/

二、Sqlsugar 调用

//设置参数
                var parameters = new List<SugarParameter>
                {
                    new SugarParameter("p_HospId", HospId),
                    new SugarParameter("p_strDate", strDate),
                    new SugarParameter("p_endDate", endDate),
                    new SugarParameter("p_page_size", pageSize),
                    new SugarParameter("p_page_number", page),
                    new SugarParameter("p_result", "")
                        { IsRefCursor = true, Direction = System.Data.ParameterDirection.Output },
                    new SugarParameter("p_total_count", 0)
                        { Direction = System.Data.ParameterDirection.Output }
                };
                //执行存储过程
                var resultList = db.Ado.SqlQueryAsync<OutpatientReportStatistics>("BEGIN GetPatientVisitData(:p_HospId, :p_strDate, :p_endDate, :p_page_size, :p_page_number, :p_result, :p_total_count); END;", parameters).Result.ToList();
                //总行数
                var totalItem = Convert.ToInt32(parameters[6].Value);
