Yes, there is a scenario we support for Execute that isn't supported for Query, specifically: to run the same operation sequentially with a range of different parameter values. This makes sense for Execute, but for query it probably means you should be looking at a different query using in....
创建一个参数对象(Parameter Object)来传递多个参数的值。参数对象可以是一个匿名对象或者是一个自定义的类。例如,我们可以创建一个匿名对象来存储多个参数的值: 代码语言:txt 复制 var parameters = new { param1 = value1, param2 = value2, param3 = value3 }; 使用Dapper的Query或Execute方法来执行SQL查询...
parameter.Add("@Id", con.Id, dbType: DbType.Int32, direction: ParameterDirection.InputOutput); parameter.Add("@FirstName", con.FirstName); parameter.Add("@LastName", con.LastName); parameter.Add("@Company", con.Company); parameter.Add("@Title", con.Title); parameter.Add("@Email", ...
QueryParameter qp = new QueryParameter(); qp.listWhere = pageWhere.queryWhere.listWhere; pageWhere.queryWhere.dicWhere.ForEach(item => { qp.dynamicParameter.Add(item.filed, item.value); }); return _prerecordBLL.GetList(qp, pageWhere.pageSize, pageWhere.pageIndex, pageWhere.filedOrder); 调...

parameter.DbType = DbType.String; } public override Point Parse(object value) { if (value is string strValue) { var parts = strValue.Trim('(', ')').Split(','); if (parts.Length == 2 && double.TryParse(parts[0], out double x) && double.TryParse(parts[1], out double y)) ...
3、SugarParameter[] 或者List<SugarParameter > 2、根据Sql查询单条 Dapper根据Sql查询单条 /// ///查询第一个数据 /// /// /// ///<returns></returns> publicstaticT QueryFirst(stringsql,objectparam) { using(SqlConnection con =newSqlConnection(connectionString)) { returncon.QueryFirst...
GetPageList():新增分页查询 另新增数据库环境支持Oracle 三.举栗子 这里用上面的方法来简单的测试一下。 1 using System; 2 using System.Collections.Generic; 3 using System.Data; 4 using System.Data.SqlClient; 5 using System.Linq; 6 using System.Text; ...
vars=newSugarParameter("@p",value); s.TypeName="dtTableName"; 四、类型转换:在Dapper中很多类型做了兼容处理。 比如:数据库中是string,但值是int SELECT CAST( id as nvarchar) id FROM users Dapper中Query实体时,id允许定义为string, 答:Sqlsugar中类型只支持int转string,不支持string转int ...
