Replacing columnn name programmaticall y

Hi,

The following script does not return any resultset against a test db
while I know for a fact tables with letter "aaa" has columns that
contains "ccc".
What's wrong? the the inner cursor?

Thanks.
-- get all tbls with letter aaa
declare @tbl varchar(8000)
declare tblCursor cursor for
SELECT name
FROM sysobjects
WHERE xtype = 'U'
AND name LIKE '%aaa%'

open tblCursor
fetch next from tblCursor
into @tbl

while (@@fetch_status = 0)
begin

-- get all columns with letter ccc and replace it with nothing /
remove it
declare @tbuffer varchar(4000)
declare @cbuffer varchar(8000)

declare abnormal_cols cursor for
SELECT o.name, c.name
FROM sysobjects o
JOIN syscolumns c ON o.id = c.id
WHERE o.xtype = 'U'
AND c.name LIKE '%ccc%'
and o.id = object_id('+@tb l')
-- ORDER BY c.name

open abnormal_cols
fetch next from abnormal_cols
into @tbuffer,@cbuff er

while (@@fetch_status = 0)
begin
-- EXEC sp_rename '+@tbuffer+'.['+@cbuffer+']','+Replace(+@c buffer+','%ccc% ','')',
'COLUMN';
-- test
print @tbuffer + ', ' + @cbuffer;
fetch next from abnormal_cols
into @tbuffer,@cbuff er
end

close abnormal_cols
deallocate abnormal_cols;

fetch next from tblCursor
into @tbl

end
close tblCursor
deallocate tblCursor;

Hi

I can't see why there are two cursors here, try:

SELECT o.name, Replace(c.name, 'ccc','') as NewName, c.name as OldName
FROM sysobjects o JOIN syscolumns c ON o.id = c.id
JOIN syscolumns a ON o.id = a.id
WHERE o.xtype = 'U'
AND c.name LIKE '%ccc%'
AND a.name LIKE '%aaa%'

I've got a bunch of code that runs under a bunch of unit tests. It'd be really handy if when testing I could supply replacement functionality to verify that the right things get called without those things actually getting called, since frequently those calls take a long time to execute and do things that, well, I don't really want to do. E.g. imagine you've got a routine which takes a filespec, generates a list of files, and copies...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
