Data Hashing Issue
We are trying to insert the data from temp table to main table in SQL server. We have encountered the below issue While hashing the data.
Please find the attached query used for insertion and received the below mentioned error message.
INSERT INTO hash2(email) (SELECT CDWH_REP.DBO.UDF_HASHBYTES('SHA256',email) as email from hash1)
USE [CD_REP]
GO
/****** Object: SqlAssembly [hashCLR] Script Date: 6/20/2024 9:12:06 AM ******/
CREATE ASSEMBLY [cryptohashCLR]
from (hashing_value)
WITH PERMISSION_SET = SAFE
GO
USE [CD_REP]
GO
/****** Object: UserDefinedFunction [dbo].[udf_hashBytes] Script Date: 6/20/2024 9:12:45 AM ******/
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
CREATE FUNCTION [dbo].[udf_hash](@hashtype [nvarchar](max), @input [nvarchar](max))
RETURNS [nvarchar](max) WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [cryptohashCLR].[cryptohashCLR.SqlHash].[CLRHash]
GO
Note- We can successfully execute the same query in prod.
Msg 6522, Level 16, State 1, Line 4
