Lookup Table 1:

CREATE TABLE [dbo].[LT1](
[LT1_ID] [varchar](25) NULL,
[Desc] [varchar](25) NULL);

insert into [LT1] ([LT1_ID] ,[Desc]) values ("Cat_Code","Category"),
("Prod_Code", "Product")

Lookup Table 2:

CREATE TABLE [dbo].[LT2](
[LT2_ID] [varchar](25) NULL,
[Val] [varchar](25) NULL);

insert into [LT2] ([LT2_ID] ,[Val]) values ("Drama__Q__M", "Drama"),
("Comedy__Q__M", "Comedy"),
("Blue__Q_Ray", "BlueRay")

I have another table with the below information

CREATE TABLE [dbo].[History](
[Content] [varchar](25) NULL);

insert into [History] ([Content]) values ("Changed Cat_code to Drama__Q__M From Null"),
("Changed Product_code to Blue__Q__Ray From Null"),
("Assigned to AAA"),
("Changed Cat_code to Comedy__Q__M From Drama__Q__M");

I need to get the lookup values from the lookup tables LT1 and LT2 and replace the respective LT1_ID and LT2_ID value with Desc and Val values from look up tables 1 and 2. the output should look like this

Changed Category to Drama From Null
Changed Product to BlueRay From Null
Assigned to AAA
Changed Category to Comedy From Drama

Can any one please help me in resolving this?

Thank you

I have 2 lookup tables. I need to get and replace the values from the lookup tables for the below data.

Lookup Table 1

LT_ID Desc
Cat_Code Category
Prod_Code Product

Lookup Table 2

LT_ID Desc
Drama__Q__M Drama
Comedy__Q__M Comedy
Blue__Q_Ray BlueRay

I have another table with the below information

1 Changed Cat_code to Drama__Q__M From Null
2 Changed Product_code to Blue__Q__Ray From Null
3 Changed Cat_code to Comedy__Q__M From Drama__Q__M

from the above I need an output like below

1 Changed Category to Drama From Null
2 Changed Product to BlueRay From Null
3 Changed Category to Comedy From Drama

Can anyone please provide the solution for this?

Thank you in advance


In order to help we will need a few things:

1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data

Please take a few minutes and read the first article in my signature for best practices when posting questions.
