Okay I will simplify my steps:


The TEST ddl is the data that has commands that specify changes to the tables.

My objective is to do those specified commands which can either be insert update or delete.

The TEST ddl has a column named COMMAND which will have insert update or delete.
The TEST ddl has a column named ERRORMESSAGE; this specifies which table to run the commands on.
So, my rules are:

O14* dictates use of FOURTEEN_ALL table
HH* dictates use of HH_ALL table
HL* dictates use of HH_LISTING table
ED* dicatates use of EDUCATION table

All that I am to do is run the commands and display what commands are being executed.


OK now I understand what you are after. Can you post some sample data for test so I have something to work with?

By my count you have 4 possible tables each with a possible 3 commands. That means you would need to have 12 queries similar to my first post.

How many rows are in the test table during a typical run?

OK then this will greatly benefit from a set based approach instead of a cursor. Thanks for the sample data but we still need some rows for the TEST table because that is the driver for this whole process as I understand it?

Yes you are right. I had to generate some sample data. It took longer than I anticipated. But I have just posted it before this post.

This should cover the Updates and Deletes. I don't understand how the insert logic is supposed to work.

declare @SQL varchar(max) = ''

--First is the updates
select @SQL = stuff ((
select
'Update dbo.' +
case ERRORMESSAGE
when 'ED ERROR' then 'Education'
when 'O14 ERROR' then 'FOURTEEN_ALL'
when 'HL ERROR' then 'HH_LISTING'
when 'HL ERROR' then 'HH_ALL'
end
+ ' set ' + Columns_To_Fix + ' = ''' + Corrected_Value
+ ''' where zBarcode = ' + cast(zBarcode as varchar(20))
+ ' and PERSON_NUMBER = ' + cast(Person_No as varchar(20)) + ';' as MyVal
from test
where Command = 'UPDATE'
for XML PATH(''), type
).value('.','varchar(max)'), 1, 0, '')

--Now we append the deletes
select @SQL = @SQL + stuff ((
select
'DELETE dbo.' +
case ERRORMESSAGE
when 'ED ERROR' then 'Education'
when 'O14 ERROR' then 'FOURTEEN_ALL'
when 'HL ERROR' then 'HH_LISTING'
when 'HL ERROR' then 'HH_ALL'
end
+ ' where zBarcode = ' + cast(zBarcode as varchar(20))
+ ' and PERSON_NUMBER = ' + cast(Person_No as varchar(20)) + ';' as MyVal
from test
where Command = 'UPDATE'
for XML PATH(''), type
).value('.','varchar(max)'), 1, 0, '')

select @SQL

--exec sp_execute @SQL

Thanks, I think I could to the inserts.

The same logic applies basically and insert the corresponding data that is necessary.

Thanks for your help

This should cover the Updates and Deletes. I don't understand how the insert logic is supposed to work.

declare @SQL varchar(max) = ''

--First is the updates
select @SQL = stuff ((
select
'Update dbo.' +
case ERRORMESSAGE
when 'ED ERROR' then 'Education'
when 'O14 ERROR' then 'FOURTEEN_ALL'
when 'HL ERROR' then 'HH_LISTING'
when 'HL ERROR' then 'HH_ALL'
end
+ ' set ' + Columns_To_Fix + ' = ''' + Corrected_Value
+ ''' where zBarcode = ' + cast(zBarcode as varchar(20))
+ ' and PERSON_NUMBER = ' + cast(Person_No as varchar(20)) + ';' as MyVal
from test
where Command = 'UPDATE'
for XML PATH(''), type
).value('.','varchar(max)'), 1, 0, '')

--Now we append the deletes
select @SQL = @SQL + stuff ((
select
'DELETE dbo.' +
case ERRORMESSAGE
when 'ED ERROR' then 'Education'
when 'O14 ERROR' then 'FOURTEEN_ALL'
when 'HL ERROR' then 'HH_LISTING'
when 'HL ERROR' then 'HH_ALL'
end
+ ' where zBarcode = ' + cast(zBarcode as varchar(20))
+ ' and PERSON_NUMBER = ' + cast(Person_No as varchar(20)) + ';' as MyVal
from test
where Command = 'UPDATE'
for XML PATH(''), type
).value('.','varchar(max)'), 1, 0, '')

select @SQL

--exec sp_execute @SQL



So the insert logic is to insert a new row with only certain columns that are defined in the test table? So it will only insert a single column plus zBarcode and PERSON_NUMBER? Let me know if you can't figure it out and I can lend a hand.

I know I said it before but you really would gain a lot of benefit from normalization on your tables.
