Data Warehousing :: Creating A Table With Column Store Index?
Sep 26, 2015I am trying to create a sample table in the Azure SQL Data warehouse but its giving me a syntax error Incorrect syntax near the keyword 'CLUSTERED'.

SQL Tools :: Adding Column To A Table Causes Copying Data Into Temp Table
Sep 23, 2015If on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?
BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,
[Code] ....
The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.

Data Warehousing :: Cannot Insert Value NULL Into Column When Executing Stored Procedure
Sep 22, 2015I received this stored procedure that I modified to run on my system. Specifically, I only changed the database and filter text and left the rest alone. When I execute the stored procedure, I get the error:
Msg 515, Level 16, State 2, Procedure ObjectNotesInsert, Line 18
Cannot insert the value NULL into column 'RefRowPointer', table 'pSCI_App.dbo.ObjectNotes'; column does not allow nulls. INSERT fails. The statement has been terminated.
Here is the actual stored procedure I am running. I should add that I can execute each step and get results and if I hard code the resulting values into the procedure, the execution works.

Transact SQL :: Key And Indexes On Two Column Data Table Or Parsed View (Large String Of Data And Filename)
Oct 4, 2015I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string based
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?

Data Warehousing :: Hiding Text Box Based On Table Property
Oct 16, 2015I am putting together an invoice for my company. I have a text box describing each section of the invoice, followed by a table to list out the charges. I am using multiple tables based on what type of charge the client is receiving.
I would like to hide each section if there are no items purchased of that type. I can do this with the table using the expression "=CountRows() < 1", but I do not know how to refer to that table (call it Tablix1 for the sake of discussion) for the text box.

View 4 Replies View RelatedAdding Column To A Table Before An Existing Column
Mar 30, 2004I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.

Adding Column To Table
Dec 18, 2001I have a table size 2078mb, number of row +530,900. Is it normal for sql to lock users out of the db when I add a column to the end of the table? I'm running SQL 7.0. The table has 4 col regular indexes. No primary keys. It locked the user out for about 10 min. I thought with SQL 7.0 this problem went away?
View 1 Replies View RelatedAdding A Column To A Table
Feb 24, 2003Can I add a column to a database table without dropping and recreating the table?
The problem is that everytime a user creates an action that requires a new table - at the moment I drop the table and recreate the table with the new column.
This requires lots of resources as I have to populate the table again.
Is there a design way I can go around this?
Adding A New Data Column (not Derived) Midway Thru A Data Flow
Jan 5, 2006I need to know what a table's max row Identity is part way thru a data flow. I can't get it at the beginning of the data flow. I need to either (1) add it to the data buffer part way thru or (2) set it into a package variable and then reference the var in a script component.
I've not found a way to add a database column to the data buffer without doing a lookup for each row (too slow and not appropriate here) or some goofy oledb source and then merge join into the data buffer on a contrived join.
I've read questions about referencing package vars in scripts but I can't get that to work. DTS.Variables("varname").Value isn't recognised when I code it up.
Anyone have an idea or solution for either one of these? If you're gonna explain the script code, please include the entire snipet including the INCLUDEs, etc.

Adding And Populating A Column To Existing Table
Dec 5, 2005Sorry I'm pretty new to SQL so I don't know if this is a simple question. I have a table, and I am trying to add a column to the table and populate this column using what would be called an 'IF' function in Excel.
Basically 'column A' has numbers in it. I want SQL to look at 'column A' and if the first 5 digits of the number in 'column A' are 00001, then put 'description A' into new column 'column B'. If the first 5 digits of the number in 'column A' are 00002, then put 'description B' into 'column A' etc.
Any ideas?
Adding Column With Primary Key In Existing Table
Jan 21, 2014I want to add new primary key into existing table which already has a primary key. But,I do not want to remove the old primary key, since there are many records and the old primary key also have relationship with other table
When I am using this query:
alter table hem154
add indexNO uniqueidentifier default newid()
alter table hem154
add CONSTRAINT pk_hem154_indexNo PRIMARY KEY (PK_indexNO)
go
Note:
Hem154 ~ Table name
indexNo ~ Column Name
I get this runtime error:
Msg 1779, Level 16, State 0, Line 1
Table 'hem154' already has a primary key defined on it.
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
Adding A Column To VLDB 200GB Table
May 1, 2007The column I'm adding needs to be part of the clustered PK (it will be the last of three columns) so I need to recreate all the indexes.
My DB is set for FULL recovery mode ALLOW_SNAPSHOT_ISOLATION ON. I've tried two methods so far.
Method 1:
BEGIN TRANSACTION
CREATE TABLE dbo.Tmp_copyoftablewithnewfield
(
) ON PRIMARY
IF EXISTS(SELECT * FROM dbo.originaltable)
EXEC('INSERT INTO dbo.Tmp_copyoftablewithnewfield (<original fields>)
SELECT <original fields> FROM dbo.originaltable WITH (HOLDLOCK TABLOCKX)')
GO
DROP TABLE dbo.originaltable
GO
EXECUTE sp_rename N'dbo.Tmp_copyoftablewithnewfield', N'originaltable',
'OBJECT'
GO
<recreate PK constraint>
<rebuild indexes>
COMMIT
Pro's: Lets me add the new field in the spot I'd like it (not a big deal)
Con's: Tons of wasted space and time. It took about 15 hours.
Method 2:
SET XACT_ABORT ON
GO
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
GO
BEGIN TRANSACTION
<drop PK constraint>
<drop indexes>
ALTER TABLE [dbo].[originaltable] ADD
[newfield] [tinyint] NOT NULL CONSTRAINT [DF_originaltable_newfield] DEFAULT
((1))
<recreate PK constraint>
<rebuild indexes>
COMMIT TRANSACTION
Pro's: No making a copy of the entire table taking up 200GB more space in the db data file
Con's: My tempdb grew to accomodate the row versioning info for every row in the 200GB table. It took over 30 hours.
A lot of time and disk space is wasted with both.
Since the db is going to be unavailable to users I have some flexibility here. I was considering turning ALLOW_SNAPSHOT_ISOLATION OFF and then trying method 2 again which should stop the versioning in tempdb and then turning it back on.
I was also curious if setting the database recovery mode to SIMPLE would cut down on db log usage and then I could set it back to FULL when done.
Do these really need to be in a transaction? If there's some hardware failure or something unexpected I can just restore from backup and do the conversion again. If the presence of the transaction itself is causing more disk usage for logging or any other slowdown, I think I'd rather do without.
Given the amount of time this conversion takes, I wanted to get some
feedback other than "just try it" before doing any new tests.
Thanks.
Adding A Not Null Column To Replicated Table
Apr 23, 2007Hi,
I'm merge replicating a SQL Server 2005 database (publisher) to SQL Compact databases (subscribers) on mobile devices. I understood that I could add a "not null" column to a replicated table on the server as long as I specified a default value, but it seems this is not possible. I ran the following script on the server database:
ALTER TABLE Activity ADD ActivityRequiresProject bit not null default(0)
which executed OK. When I went to synchronize the db on the mobile device I got the following error:
Alter table only allows columns to be added which can contain null values. The column cannot be added to the table because it does not allow null values.
The SQL statement failed to execute. If this occurred while using merge replication, this is an internal error. If this occurred while using RDA, then the SQL statement is invalid either on the PULL statement or on the SubmitSQL statement. [ SQL statement = alter table "Activity" add "ActivityRequiresProject" bit not NULL constraint "DF__Activity__Activi__4A47DDAE" default ( ( 0 ) ) ]
Does anyone know if this is a valid error? Is is possible to add a not null column with default, and if not how do I update the schema on a replicated database?
Regards,
Greg

Adding Dataset Column Values To My Table At The End

I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000.

Problem Adding NOT NULL Column To Replicated Table
Jan 15, 2003I'm new to replication and am trying to determine the best approach to add a column (NOT NULL with no DEFAULT) to a replicated table. The only success I have had is if I do the following:
Delete entire Subscription
Delete entire Publication
Add column to table
Create new Publication
Create new Subscription
Run SnapShot
The problem with this approach is that each step affects the entire database and not just the modified table. I think it is inefficient to redo replication for a simple object change. What am I missing? Is there a way to only replicate the changes made to the one table without having to run a SnapShot for the entire publication?
Keep in mind the column must be defined as NOT NULL and cannot have a Default.
Thanks, Dave
