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('+@.tbl')
-- ORDER BY c.name
open abnormal_cols
fetch next from abnormal_cols
into @.tbuffer,@.cbuffer
while (@.@.fetch_status = 0)
begin
-- EXEC sp_rename '+@.tbuffer+'.['+@.cbuffer+']','+Replace(+@.cbuffer+','%ccc%','')',
'COLUMN';
-- test
print @.tbuffer + ', ' + @.cbuffer;
fetch next from abnormal_cols
into @.tbuffer,@.cbuffer
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%'
