Copying Text Field

I am refreshing records on a target table from a similar source table (two
databases, same server) and having problems with the Text fields. I am usin
g
INSERTas follows:
delete from Trackpad4..Archived
set identity_insert Trackpad4..Archived on
insert into Trackpad4..Archived
(... DEL_RECIP_NAME, DEL_RECIP_LEN, DEL_RECIP_SIG, ...)
select ... DEL_RECIP_NAME, DEL_RECIP_LEN, null, ...
from Trackpad..Archived
set identity_insert Trackpad4..Archived off
The problem we noticed (and why I've got null populating in DEL_RECIP_SIG)
is that a simple SELECT would return three rows but a rowcount of four. A
modification of the query picked up all the rows, but the DEL_RECIP_SIG fiel
d
was blank and none of the following fields displayed. Using null at least
allows the SELECTs to perform as expected and the later columns to be handle
d
properly.
My thought was to use a UPDATETEXT wrapped in a cursor to finish the job.
But the test displayed below, while it did populate the target text field,
again rendered the later columns apparently non-existent. Also, the
gobbledygook (some sort of encoded representation of a person's signature) i
n
the source and target DEL_RECIP_SIG fields don't match.
DECLARE @.ptrval_source varbinary(16)
, @.ptrval_target varbinary(16)
, @.Length_Source int
, @.Length_Target int
SELECT @.ptrval_source = TEXTPTR(DEL_RECIP_SIG)
, @.Length_Source = DEL_RECIP_LEN
FROM trackpad..old_data
where PKG_NUM = 'W44287093174'
print 'Source'
print @.ptrval_source
print @.Length_Source
/*
update Trackpad4..Old_Data
set DEL_RECIP_SIG = 'placeholder'
where PKG_NUM = 'W44287093174'
*/
select @.ptrval_target = TEXTPTR(DEL_RECIP_SIG)
, @.Length_Target = len(cast(DEL_RECIP_SIG as varchar(8000)))
FROM trackpad4..old_data
where PKG_NUM = 'W44287093174'
print 'Target'
print @.ptrval_target
print @.Length_Target
print 'source'
readtext trackpad..old_data.DEL_RECIP_SIG @.ptrval_source 0 @.Length_Source
print 'target'
readtext trackpad4..old_data.DEL_RECIP_SIG @.ptrval_target 0 @.Length_Target
print 'update'
UPDATETEXT trackpad4..old_data.DEL_RECIP_SIG @.ptrval_target 0
@.Length_Target trackpad..old_data.DEL_RECIP_SIG @.ptrval_source
print 'target'
readtext trackpad4..old_data.DEL_RECIP_SIG @.ptrval_target 0 @.Length_Target
I tried copying the source table over through DTS, but target text fields
were empty. I was able to restore from a backup. All I can think is that
I'm not properly delineating the field going into the target record and its
violating SQL's internal rules for terminating fields and records.
Thanks for any insight,
KevinHi Kevin
You don't say what SQL Server versions you are using?
This was a problem with DTS!

If you set the value for specific DEL_RECIP_SIG to NULL you will find out
the one that is causing this issue.

Thanks for the reply. I'm using SQL 2000, SP3. I've tried this operation
in TSQL and DTS - same results. The UpdateText operation also didn't work -
seemingly the stored text data wasn't terminated properly, and following
fields in the record were not rendered at all. In any event, the target tex
t
did not resemble the source text.
If you can think of anything else, thanks in advance.

copying table from one database to another

I would like to copy a table from one database to another. These two
databases reside in two different servers/instances? Is this possible? If so,
how can I code it in m C++ application? Thanks!
You have 2 choices, Database solution or client based solution.
Database: Have your DBA create a linked server connection to server2 on
server1. Now you can execute this statement from server1
INSERT MyDest (column_list) SELECT column_list from
server2.mydb.dbo.MySource where ...
Client based solution:
Setup ADO connection to both servers. Populate a recordset from the source db
Iterate through this recordset and insert records in destination using a
procedure that has your insert logic.
