How to write custom query which shows last two records added only.

Posted: 01 Apr 2013 06:04 PM PDT

For Insurance where logic is something like after renewing a policy that renewed policy is current policy and previous policy will not be current anymore. Now want to show customer this last two records i.e. renewed policy as well as original policy which was renewed. And while renewing current policy of original policy will become previous policy for renewed policy. query i am using to show current policy only or renewed policy is something like:select * from table_name where is_current='Y'Modified to select * from table_name where person_id=somevalue OR Prev_PolNO=Curr_PolNobut still it doesn't give correct result.So can same be achieved.......

Cannot convert between Unicode & Non Unicode Strings Error

Posted: 01 Apr 2013 03:41 PM PDT

Hi,I have a SSIS package that imports an ADO.Net source file & inserts into an OLEDB Destination.There are about 25 fields but one field errors when tryingto run this task.The field represents an Account number which is a varchar (15) in both the source & destination tables.I tried fixing this by adding a Data Conversion node to change the Account number from DT_WSTR to DT_STR as I found an answer on a forum about this problem but no luck, same error.Can anyone advise how I can fix this & why does it happen?Thanks

Can I move the older ERRORLOG files?

Posted: 01 Apr 2013 01:22 PM PDT

Hi all,Long story short, we had a process that was filling up our log file at an impressive rate (impressive in a bad way). We got everything under control and that particular error log file is no longer the "current" one. However, it's taking up quite a bit of space on one of our drives. So, I'd like to move it to another drive to free up some extra room.I know I can cycle the log files until the log file in question just gets auto-deleted, but I'd like to keep it around a bit longer so we can look through it and troubleshoot.Can I manually move the files (such as ERRORLOG.2, ERRORLOG.3, etc)? Is there a super secret sp for doing this? How does SSMS like having those files manually moved without its consent?Thanks!

Discrepancy between sys.master_files and sys.database_files

Posted: 01 Apr 2013 05:19 AM PDT

Hi all,I have discrepancy beetween sys.master_files and sys.database_files in size column. Couple of days ago I changed the size of a log file for one database, however it's not reflected in sys.master_files. Views sys.database_files and sys.sysfiles are OK, they show right value. Is sys.master_files outdated? Should I run some DBCC to update it ?Thanks

Cardinality Issue

Posted: 01 Apr 2013 02:15 AM PDT

I have a 100,000,000 row table with a GUID primary key. (This is an IBM FileNet/ECM database, and utility query.)The following query:[code="sql"]SELECT TOP 9999 * -- Edited for brevityFROM DocVersion T0WHERE (T0.home_id IS NULL AND ( ( storage_area_id = N'{18CDA09D-00B2-427F-9016-C78844AA92AE}' OR storage_location =N'FNFS:/{18CDA09D-00B2-427F-9016-C78844AA92AE}')) AND (( object_id > N'{42D1BB3B-53F2-462D-A277-1AFF39548364}'))) ORDER BY object_id ASC option (recompile)[/code]is making a cardinality error on object_id. It estimates it will have 10,000 - 20,000 rows on the greater-than comparison, but the actual row count is 46M.Based on this error, it goes for a seek of the primary key, and as such, it takes 4-6 hours to seek 46M times. The scan would be 13 minutes.What I don't understand is 1) Why it is reaching this error, and 2) How to resolve it.The primary key is on the object_id, which is a GUID.This historgram details on the object_id are:[code="plain"]RANGE_HI_KEY RANGE_ROWS EQ_ROWS DISTINCT_RANGE_ROWS AVG_RANGE_ROWS ff4c80d6-98b7-46ef-97f0-[b]0000003c6313[/b] 0 1 0 1 9da7159c-a90e-48e3-84f1-[b]01ef6ded77e4[/b] 319998 1 319998 140b75dcf-55c1-4371-83e5-[b]04b0ea3cea3f[/b] 267887 1 267887 1 e2aed122-0e41-40a2-9296-[b]0ea384fd1a1d[/b] 1608631 1 1608190 1.000275e0fbf953-9a39-4d49-bbc6-[b]132a32003da4[/b] 536035.9 1 536036 1 e9b6e490-233e-40ba-a4e4-[b]19179b42e6c[/b] 5536035.9 1 536036 1 --------------------------------------------------0b8fc800-047f-5eb2-bfb9-[b]1b3e9999571f[/b] 536035.9 1 536036 1 0aa19a05-047f-5eb2-bfb9-[b]1b3e9999571f[/b] 804184.8 1 804094 1.000112(continued...169 steps total)[/code]I believe GUIDs are ordered by the last segment of the guid, and that belief is reflected in this histo. I put a dotted line in the histo: Everything below the line (including the remainding 161 steps) would match the query predicate on object_id.Why in the world does the PK seek think there are only 20k rows? Each step has over 100,000 rows.Thanks for your consideration,@SixStringSQL

Duplicating rows based on another table

Posted: 01 Apr 2013 01:51 AM PDT

Hi,I have some data in table a which has a unique identifier called column nd. I have another table, table b, which has that unique identifier, again called nd and another column called j which is a number between 10-20.How can I return the results on table a, but I want a row for each nd times the result in column j where nd is the same in both tables.For example, if nd is equal to small, and j is equal 10 the results from that query would be 10 rows of the word small.Hope that makes sense.Thanks
