Read Data attributes or Custom Attributes in SQL server from string - sql

Question

I want in SQL prepared dynamic query based on the shortcode.
For Eg.
DECLARE #ShortCode VARCHAR(MAX)
SET #ShortCode = '[User data="Name" data="MobileNumber"]';
User = table name
Name = User table field
MobileNumber = User table field
Query output be like
SELECT [Name],[MobileNumber] FROM [dbo].[User]
SET #ShortCode = '[Country data="Name" ID="1"]';
Country = table name
Name = Country table field
ID = User table field
Query output be like
SELECT [Name] FROM [dbo].[Country] WHERE [ID] = 1
How to extract all data attributes values and how to get User in the []
This functionality is done in C#
Here My c# code
// Model class
public class ShortCodeResult
{
public Guid? ID { get; set; }
public string TableName { get; set; }
public bool IsValidShortCode { get; set; }
public string Message { get; set; }
public Dictionary<string,object> KeyValue { get; set; }
public ShortCodeResult() {
KeyValue = new Dictionary<string, object>();
ID = Guid.NewGuid();
}
}
//Regex Filter
public class RegexFilter
{
private string oPattern = #"(\w+)=[\""]([a-zA-Z0-9_.:\""]+)";
public ShortCodeResult GetShortCodeValues(string Code)
{
var oShortCodeModel = new ShortCodeResult();
var oRegex = new Regex(oPattern, RegexOptions.IgnoreCase);
var oTableNameRegex = Regex.Match(Code, #"\b[A-Za-z]+\b", RegexOptions.Singleline).Value;
var lstMatchCollection = oRegex.Matches(Code).Cast<Match>().Where(x=>x.Value.StartsWith("data")).ToList();
if (lstMatchCollection != null && lstMatchCollection.Count > 0)
{
for (int i = 0; i < lstMatchCollection.Count; i++)
{
var oSelected = new Regex("[^=]+$").Match(Convert.ToString(lstMatchCollection[i]));
if (oSelected != null)
{
oShortCodeModel.KeyValue.Add(i.ToString(), oSelected.Value.Trim('"'));
}
}
}
oShortCodeModel.TableName = oTableNameRegex;
return oShortCodeModel;
}
}
//HtmlHelper Extension
public static MvcHtmlString RenderShortCode(this HtmlHelper htmlHelper, string IdOrExprssion)
{
#region Get short code data
var oShortCode = ShortCodeHelper.GetShortCode(IdOrExprssion);
#endregion
var oMvcHtmlString = new MvcHtmlString(IdOrExprssion);
var oRegexFilter = new RegexFilter();
var shortCodeModel = oRegexFilter.GetShortCodeValues(oShortCode.Expression);
var ostringBuilder = new StringBuilder();
if (!string.IsNullOrEmpty(shortCodeModel.TableName))
{
ostringBuilder.AppendLine("SELECT ");
ostringBuilder.AppendLine((shortCodeModel.KeyValue.Count > 0 ? string.Join(",", shortCodeModel.KeyValue.Select(x => x.Value)) : "*"));
ostringBuilder.AppendLine(" FROM ");
ostringBuilder.AppendLine(oShortCode.TableName);
ostringBuilder.AppendLine(" WITH(NOLOCK) ");
if (oShortCode.FilterCode.Count() > 0)
{
ostringBuilder.AppendLine("WHERE ");
foreach (var filterCode in oShortCode.FilterCode)
{
ostringBuilder.AppendLine(filterCode.FilterColumnName);
ostringBuilder.AppendLine(filterCode.Operator);
ostringBuilder.AppendLine(filterCode.FilterColumnValue);
}
}
}
var oDyanamicData = DBHelper.GetDataTable(ostringBuilder.ToString(), System.Data.CommandType.Text, new List<SqlParameter>());
if (oDyanamicData != null)
{
if (oShortCode.IsHtmlRender)
{
for (int i = 0; i < oDyanamicData.Rows.Count; i++)
{
for (int j = 0; j < oDyanamicData.Columns.Count; j++)
{
string key = Convert.ToString(oDyanamicData.Columns[j]);
string value = Convert.ToString(oDyanamicData.Rows[i].ItemArray[j]);
if (oShortCode.DisplayCode.Count > 0)
{
var displayCode = oShortCode.DisplayCode.FirstOrDefault(x => x.DisplayColumnName == key);
if (displayCode != null && !string.IsNullOrEmpty(displayCode?.ReplaceKey))
{
oShortCode.DefinedHtml = oShortCode.DefinedHtml.Replace(displayCode.ReplaceKey, value);
}
}
}
}
return new MvcHtmlString(oShortCode.DefinedHtml);
}
else
{
string key = string.Empty, value = string.Empty;
#region For Json
List<JObject> dataList = new List<JObject>();
for (int i = 0; i < oDyanamicData.Rows.Count; i++)
{
JObject eachRowObj = new JObject();
for (int j = 0; j < oDyanamicData.Columns.Count; j++)
{
key = Convert.ToString(oDyanamicData.Columns[j]);
value = Convert.ToString(oDyanamicData.Rows[i].ItemArray[j]);
eachRowObj.Add(key, value);
}
dataList.Add(eachRowObj);
}
return new MvcHtmlString(Newtonsoft.Json.JsonConvert.SerializeObject(dataList));
#endregion
}
}
return oMvcHtmlString;
}
Can anyone help me solved above in SQL server or prepared query in store procedure
