示例1: Retrieve
public List<Cosa> Retrieve(int pageSize, int page, out long totalRows, string filtro, string filtro2 )
{
List<Parameter> parametros = new List<Parameter>();
var db = new Db();
var sqlDataFields = " SELECT * ";
var sqlScalarField = "SELECT COUNT(datakey) ";
var sqlDataFrom = new StringBuilder(" FROM toomuchdata ");
bool first = true;
var parmList = new List<object>();
if(filtro!=null)
{
sqlDataFrom.AppendFormat(first ? " WHERE " : " AND ");
sqlDataFrom.AppendFormat(" fielddata1 LIKE :fielddata1");
parmList.AddRange(new[] { ":fielddata1", filtro });
parametros.Add(new Parameter());
first = false;
}
if (filtro2 != null)
{
sqlDataFrom.AppendFormat(first ? " WHERE " : " AND ");
sqlDataFrom.AppendFormat(" fielddata1 LIKE :fielddata2");
parmList.AddRange(new[] { ":fielddata2", filtro2 });
first = false;
}
//Se saca el scalar
var sqlScalar = string.Format("{0}{1}", sqlScalarField, sqlDataFrom);
var limit = " LIMIT " + pageSize + " OFFSET " + (page - 1);
sqlDataFrom.Append(limit);
totalRows = (long)db.Scalar(sqlScalar,parmList.ToArray());
return db.Read(string.Format("{0}{1}", sqlDataFields, sqlDataFrom), Make2, parmList.ToArray()).ToList();
}
