상기 Libary를 이용하면 Json을 이용한 컨트롤이 Javascript에서 손쉽게 이루어 질 수 있을 것으로 판단한다.

  1. XML 파일 또는 포멧의 자료를 “XML to JSON – a converter”를 이용하여 JSON으로 변경
  2. “Sesseion variables without cookies”를 이용하여 해당 페이지에 저장(새로고침을 하여도 해당 창이 닫히기 전까지는 유지되는 기능 활용)
  3. “JSON Query Engine”을 이용하여 CRUD(Create, Read, Update, Delete) 작업 수행 및 반영

그냥 설명은 무시하고 예제 소스로 그냥 진행합니다.

DataSet이 아닌 일반 DataTable을 이용하는 방법도 동일합니다.

 

DataSet 생성

DataSet ds = new DataSet();
DataRow dr = null;
DataTable dt01 = new DataTable();
dt01.TableName = "Test01";
dt01.Columns.AddRange(new DataColumn[] {
        new DataColumn { ColumnName ="no", Caption = "일련번호", DataType=typeof(int), DefaultValue = 0}
        , new DataColumn { ColumnName ="col", Caption = "컬럼명", DataType=typeof(string), DefaultValue = string.Empty}
        , new DataColumn { ColumnName ="val", Caption = "값", DataType=typeof(string), DefaultValue = string.Empty}
        , new DataColumn { ColumnName ="etc", Caption = "비고", DataType=typeof(string), DefaultValue = string.Empty}
    });
dr = dt01.NewRow();
dr["no"] = 1;
dr["col"] = "COL1";
dr["val"] = "A";
dr["etc"] = "비고1";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 2;
dr["col"] = "COL2";
dr["val"] = "B";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 3;
dr["col"] = "COL3";
dr["val"] = "C";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 4;
dr["col"] = "COL4";
dr["val"] = "D";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 5;
dr["col"] = "COL5";
dr["val"] = "가";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 6;
dr["col"] = "COL6";
dr["val"] = "나※";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 7;
dr["col"] = "COL7";
dr["val"] = "~!@#$%^&*()_+`-={}[]:\";'<>?,./|\\";
dt01.Rows.Add(dr);
dr = dt01.NewRow();
dr["no"] = 8;
dr["col"] = "COL8";

dt01.Rows.Add(dr);
dr = dt01.NewRow();
dt01.Rows.Add(dr);
 
 
DataTable dt02 = new DataTable();
dt02.TableName = "Test02";
dt02.Columns.AddRange(new DataColumn[] {
        new DataColumn { ColumnName ="no", Caption = "일련번호", DataType=typeof(int), AutoIncrement = true}
        , new DataColumn { ColumnName ="etc", Caption = "비고", DataType=typeof(string), DefaultValue = string.Empty}
    });
dr = dt02.NewRow();
dr["etc"] = "비고1";
dt02.Rows.Add(dr);
dr = dt02.NewRow();
dr["etc"] = "비고2";
dt02.Rows.Add(dr);
dr = dt02.NewRow();
dr["etc"] = "비고3";
dt02.Rows.Add(dr);
dr = dt02.NewRow();
dr["etc"] = "비고4";
dt02.Rows.Add(dr);
dr = dt02.NewRow();
dr["etc"] = "비고5";
dt02.Rows.Add(dr);
dr = dt02.NewRow();
dr["etc"] = "비고6";
dt02.Rows.Add(dr);
 
ds.Tables.Add(dt01);
ds.Tables.Add(dt02);

XML 파일로 저장

ds.WriteXmlSchema(@"c:\TestForDS.xsd");
ds.WriteXml(@"c:\TestForDS.xml");

 

XML Stream을 이용하여 String에 담기

System.IO.MemoryStream mStreamXSD = new System.IO.MemoryStream();
System.IO.MemoryStream mStreamXML = new System.IO.MemoryStream();
ds.WriteXmlSchema(mStreamXSD);
mStreamXSD.Seek(0, System.IO.SeekOrigin.Begin);
ds.WriteXml(mStreamXML);
mStreamXML.Seek(0, System.IO.SeekOrigin.Begin);
System.IO.StreamReader srXSD = new System.IO.StreamReader(mStreamXSD);
System.IO.StreamReader srXML = new System.IO.StreamReader(mStreamXML);
string strXSD = srXSD.ReadToEnd();
string strXML = srXML.ReadToEnd();

 

이 방법을 이용하여 Oracle Clob 저장 및 활용
