How to update unicode text to SQL Server from query window - sql

Question

I'm using the following code:
This is Update code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[UpdateDataTable]
(#TABLEID BIGINT,
#QUERY NVARCHAR(MAX),
#DATAOBJECT NVARCHAR(MAX))
AS
BEGIN
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
BEGIN TRANSACTION TX1
-- DECLARATIONS
--DECLARE #DTABLE NVARCHAR(MAX) = 'DYNAMIC_Order_C905AE71028F4B0094B94EDAD0026CE2'
DECLARE #DTABLE NVARCHAR(MAX) = (SELECT DynamicTableId FROM TABLES WHERE Id=#TABLEID)
--DECLARE #QUERY NVARCHAR(MAX)='qty=4356'
--DECLARE #DATAOBJECT NVARCHAR(MAX)='{"product":"iPad 2018 pro", "amount":260000}'
-- BUILDING QUERY
DECLARE #QUERYSQL NVARCHAR(MAX) = 'SELECT Id AS TableId FROM '+#DTABLE+' WHERE '+#QUERY
-- RETRIEVING IDS OF UPDATING ROWS
DECLARE #UPDATING_IDS_TEMP TABLE(TableId BIGINT)
INSERT INTO #UPDATING_IDS_TEMP
EXEC sys.sp_executesql #QUERYSQL
DROP TABLE IF EXISTS #UPDATING_IDS
SELECT ROW_NUMBER() OVER (ORDER BY TableId)-1 AS Id, TableId
INTO #UPDATING_IDS
FROM #UPDATING_IDS_TEMP
-- UPDATING ROWS
DECLARE #INDEX BIGINT = 0
DECLARE #MAX BIGINT = (SELECT COUNT(*) FROM #UPDATING_IDS)
WHILE(#INDEX < #MAX)
BEGIN
--DECLARE #ROWID BIGINT = (SELECT TableId FROM #UPDATING_IDS WHERE Id=#INDEX)
DECLARE #ROWID BIGINT = 'N'''+ (SELECT TableId FROM #UPDATING_IDS WHERE Id=#INDEX) +''','
--SELECT #ROWID
EXEC FN_UpdateFieldByJson #DTABLE, #ROWID, #DATAOBJECT
SET #INDEX = #INDEX + 1
END
SELECT 'Completed'
COMMIT TRANSACTION T1
END
This is Insert Code
/****** Object: StoredProcedure [dbo].[InsertDataToTable] Script Date: 2/7/2020 1:57:07 PM ******/
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

DECLARE #fieldCount BIGINT = (SELECT COUNT(*) FROM #FIELDS)
DECLARE #index BIGINT=0
WHILE ( #index < #fieldCount)
BEGIN
SET #keyList = #keyList+'['+(SELECT [KEY] FROM #FIELDS WHERE Id=#index)+'],'
-- ADDING WITHOUT QUOTES IF IT'S A NUMBER
IF ( (SELECT [TYPE] FROM #FIELDS WHERE Id=#index) = 2 )
BEGIN
SET #valueList = #valueList+''+dbo.ZenEncToChar((SELECT [VALUE] FROM #FIELDS WHERE Id=#index))+','
END
ELSE
BEGIN
SET #valueList = #valueList+'N'''+dbo.ZenEncToChar((SELECT [VALUE] FROM #FIELDS WHERE Id=#index))+''','
END
SET #index = #index+1
END
SET #keyList=SUBSTRING(#keyList,1, LEN(#keyList)-1)
SET #valueList=SUBSTRING(#valueList,1, LEN(#valueList)-1)
SET #insertSql = #insertSql + #keyList+') VALUES('+#valueList+')'
--SELECT #insertSql
EXEC sys.sp_executesql #insertSql
--SELECT ROW_NUMBER() OVER (ORDER BY COLUMN_NAME)-1 AS Id,COLUMN_NAME
--FROM INFORMATION_SCHEMA.COLUMNS
--WHERE TABLE_NAME = #dynamicTableId
END
