3. Database Operations (taking PostgreSQL database as an example)

1 /// <summary> 2 /// batch delete 3 /// </summary> 4 [OperationContract (Name = "DeleteMdcIcdListControl")] 5 public int DeleteMdcIcdControl (List <mdc_icd10> mdc_icd10List) 6 {7 int I = 0; 8 foreach (var mdc_icd10 in mdc_icd10List) 9 {10 string sqlStr = string. format (@ "Delete from mdc_icd10 where id = {0}", mdc_icd10.Id); 11 I + = pgSqlService. executeSql (sqlStr); 12} 13 return I = mdc_icd10List.Count? 1: 0; 14}Pgsql Code
