View 1 RepliesHi all,
We are trying to migrate a SQL Server 2005 database/schema onto SQL CE. The original SQL Server 2005 schema uses views. And VIEWs are not supported on SQL CE. What can we use as an alternative?
Here are the option I can think of:
Use Tables instead of views : We are currently using this approach. But the disadvantage is that data remains on the DB. We need to clean and reuse the table everytimeCan we use a DataSet or DataTable instead? Any sample code available?
Can we replace them by some in-memory data structure?
Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.

View 1 Replies View RelatedHello.
Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.
Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?
Cheers.
I am incorporating a perl script loading data into my SQL Server. If I receive a message with a single backslash I know to replace it with a double backslash \. But what if it is a " double quote what do I need to do to get it to appear as is?

Hi i have 2 cols
col1 col2
A1 21
A2 22
A3 21
A4 23
I want to create a report such that i should see all values of col1 but in col2 i want to show only value of 21 and the remaining should be zero.
So basically all the other values except 21 should be zero in the report but should not be updated in the database.
So the report should look like
col1 col2
A1 21
A2 0
A3 21
A4 0
can you please tell me how to do that
Thanks

Hi,Is it possible to do from one script? We have a set of user's tables like"tbl%". We can get this list very easy using this script:SELECT name FROM sysobjects WHERE xtype = 'U' AND name LIKE 'tbl%' ORDER BYname;We need to change some column names if these names are in a special listthat we have. What can we do? Use FOR EACH ROW? Or what?So, I need to get a column list for each table and check if every columnname is equal to one of the names from the list and then if YES replace itby something or add some symbol to this name. Terrible or possible?Regards,Dmitri

Hi,
I would like to replace all instances of a code that starts with 'GEM' with the word 'Perfect'', and all instances of the code that starts with 'GOLD' replaced with 'Imperfect'.
For example, if I have a table named STONES, and a field within the table STONES.Code contained codes such as 'GEMPART4000', 'GEMPART5000', 'GOLDSIDE2300' and 'GOLDSIDE3000', I want to return the first two codes as the words 'Perfect' for each and the last two codes with the word 'Imperfect' for each.
Similarly, how would it be written so I could select a middle part of the code to use as the trigger to replace the code with something different, e.g. if I wanted to use the 'PART' from the first two codes?
I have discovered that the REPLACE and CASE functions don't work with % (so I am looking for any code that starts with what I stipulate but can end with anything (or using it on either side of the middle part of the code)).
Any help would really be appreciated please.
Hi Guys,
I am faced with a problem that is giving me headaches. I have t1, t2 and t3. I t1 I have students that have a reference to t2 which are the schools they belong to. The problem arises when I see that there is redundancy in t2. There more records for the same schools. This was posible in giving the same school (postcode and name make it the same school) a different ID. In t3 I removed these redundant schools by using fuzzy grouping.
My problem is I want to ensure that the students are put using the schools from t3 instead of t2. So what I need to do is is to replace the redundant id from t2 with the correct id from t3.
Please help. Thans in advance
I am trying to clean up an ugly query that's based on trying to find items that exist in one table but not the other.
My tables are like this:
ITEMSitemID,itemName,itemDescriptionetc...
ORDERITEMSOrderLineID,OrderID,itemID
ORDERSOrderID,OrderCompleted
Currently my query looks something like this:
Select Items.* from ITEMS where not exists (select 1 from ORDERITEMS inner join ORDERS on ORDERITEMS.OrderID = ORDERS.OrderID where ORDERITEMS.itemID=ITEMS.itemID and (ORDERS.OrderCompleted=1))
So this query is looking for ITEMS what don't have a corresponding entry in the ORDERITEMS table. As I understand it this is pretty inefficient as it is going to be executing the sub query in the Not Exists statement for each entry in the ITEMS table. Is the preferred method to do something along the lines of somehow making the sub query into a derived table and doing a left or right join?

View 1 Replies View RelatedHi, I have the following query.
sql = "select firstname AS Expr1, lastname AS Expr2, status AS Expr3 from person order by lastname"
Status is either 0,1,2 or 3
How can I use the query to create "a temp Alias" for the query, so that there is a "temp Alias" AS Expr4, AS Expr5, AS Expr6 and AS Expr7.
So if status = 0 then Expr4 = "true" else false
So if status = 1 then Expr5 = "true" else false
So if status = 2 then Expr6 = "true" else false
So if status = 3 then Expr7 = "true" else false
So when the reader reads Expr4 its either true or false.
Is this possible i a query?

I have a SQL table with 5000 rows in it. Some of the other SQL columns have different values but if I wanted to swap say 500 of the rows would it be something like
UPDATE Coupins
SET Name='test1,test2,test3'
WHERE Name='test4,test5,test6';
I need basically to swap the Name value of these without affecting any other values.
I've got a sproc that we are migrating from SS2K that uses the reserved keyword 'Pivot'. Best way to replace it. I think it is renameable until the select from TempDB (which is mysterious as I can't see a table in tempDB by that name!!) as below...
CREATE PROCEDURE [dbo].[sp_CreateXtab]
@select varchar(8000),
@sumfunc varchar(100),
@pivot varchar(100),
@table varchar(100),
@SQLOutput varchar(8000) OUTPUT

Hello. We have a list of 1000+ sku numbers. 90% of them start with u. I need to replace the u with T.
Concerns:
It has to only replace the first letter, if there are other "u"s in the sku, they need to remain.
Not all skus start with u, those that don't should remain the same.
I have searched and searched because I'm sure someone has requested the exact same thing but I can't find anything that is identical.
I have this so far but I know its not correct:
set sku = replace(left(sku,1),'u',right(rtrim(sku),1)+
'T')
Can someone help lead me down the right path?
Thanks in advance!!!
I'm the assistant to the assistants assistant and have no SQL base at all but have to change dates in our SQL database. I've got the script for how to do an update/replace for non date fields and have been successful at that. Unfortunately when I try to use the script to change date fields it does not work.

Below is the script that I am using, any help you can give me will help me keep my job (and pay for the beer I'm sure to need after work today) Thanks in advance for your help.
