今天在工作中遇到一个需要进行sql server分页数据查询的问题，但是分页数据查询的sql却忘记了，最终通过查询资料解决了该问题。现在把解决方法记下，以备查阅。
假设需要查询表为Test，Test表中有个字段为ID（我这里用的是int型），当前页pageIndex=5，页大小pageSize=10。则分页查询语句如下：
SELECT * FROM ( SELECT ROW_NUMBER() OVER (ORDER BY ID) AS ROWID,* FROM Test ) AS T WHERE T.ROWID BETWEEN (pageIndex-1) * pageSize+1 and pageIndex * pageSize;
/// <summary> /// 获取分页数据列表 /// </summary> /// <param name="strFieldList">查询字段</param> /// <param name="strWhere">查询条件</param> /// <param name="strOrderBy">排序字段</param> /// <param name="pageIndex">当前页</param> /// <param name="pageSize">页大小</param> /// <returns></returns> public DataSet GetListByPage(string strFieldList, string strWhere, string strOrderBy, int pageIndex, int pageSize) { StringBuilder strSql = new StringBuilder(); strSql.Append("select"); if (string.IsNullOrEmpty(strFieldList)) //去除null { strFieldList = strFieldList.Trim(); if (string.IsNullOrEmpty(strFieldList)) // 去除只有空格的字符串 { strFieldList = " * "; } } strSql.Append(" " + strFieldList + " "); strSql.Append(" from (select row_number() over (order by id) as rowid,"); strSql.Append(strFieldList + "from Test"); if (!string.IsNullOrEmpty(strWhere)) //去除null { strWhere = strWhere.Trim().ToLower(); if (!string.IsNullOrEmpty(strWhere)) // 去除只有空格的字符串 { strWhere = (strWhere.StartsWith("where")) ? " " + strWhere : " where " + strWhere; strSql.Append(strWhere); } } strSql.Append(") as t "); if (!string.IsNullOrEmpty(strWhere)) // 没有查询条件 { strWhere += " and t.rowId between {0} and {1}"; } else { strWhere = "where t.rowId between {0} and {1}"; } strWhere = string.Format(strWhere, (pageIndex - 1) * pageSize + 1, pageIndex * pageSize); strSql.Append(strWhere); if (!string.IsNullOrEmpty(strOrderBy)) //去除null { strOrderBy = strOrderBy.Trim().ToLower(); if (!string.IsNullOrEmpty(strOrderBy)) // 去除只有空格的字符串 { strOrderBy = (strOrderBy.StartsWith("order by")) ? " " + strOrderBy : " order by " + strOrderBy; strSql.Append(strOrderBy); } } return DbHelperSQL.Query(strSql.ToString()); }
