I have two tables, one a data table, the other a product table. I want to perform a join on the two tables with values distributed into columns based on the value in the month field.
Hi,Would like to know the performance differenece between Multi-columnIndex vs Single Column Indexes. Let's say I have a table with col1,col2, col3 along with a primary key column and non-indexed columns.In queries, I will use col1, col2, and col3 together and some timesjust one or two of these three columns. My questions is, should Icreate one index contains col1, col2, and col3, or create 3 seperatedcolumns. I.e. each column has its own index. Any performancedifference?Thanks a lot.
I have a view that shows the email address and first name of a Membership table. I need to add a column to this view that doesn't have a corresponding column in the original table that has some default value.
I'm trying to script a view that does a simple query to some tables. The catch is 2 of the columns are created on run time. The first column is filled with a calculation with values of other columns. The 2nd column I would like to fill with the ranking of this calculated column
Example: (imagine caculatedcol is Sum(Col1+Col2+Col3)
I am creating a view for the table: bellus=# select * from host_application_definition; id | type_value | connection_value | group_value | application_value | host ----+------------+------------------+-------------+-------------------+----
From the table meta_host_types;
id | value | types | name ----+-------+-----------+-------- 1 | agm | host-type | Rencid
I would like to seperate value into type_value and connection_value, because it holds both values.
Hi,I'm trying to create views on all my existing tables and for that I'dlike to create a script or so.I don't want to specify the '*' for the columns in the create viewstatement. I prefer to specify the column names.I have the column names int sys.columns table but Do not know how tohandle them to have a statement like that:CREATE VIEW myVIEWWITH SCHEMABINDINGASSELECT col1name, col2name, col3name, etc...from sys.columns....?????.....Anyone can help?thx,Chris
I am trying to exclude records from a table where the ID column is the same but the Mail code Column is multi-valued.For Example: (the table looks like....)
Hi, I have got a column which should multi languages data(Chinese,English etc). Source for this data is Excel. I have kept this column DataType as NVARCHAR but Chinese data is shown as 'Boxes'.But when i copy this and paste on Query pane i get proper data.
I'm working on a social network where I store my friend GUIDs in a table with the following structure:user1_guid user2_guidI am trying to write a query to return a single list of all a users' friends in a single column. Depending on who initiates the friendship, a users' guid value can be in either of the two columns. Here is the crazy sql I have come up with to give what I want, but I'm sure there's a better way... Any ideas?SELECT DISTINCT UserIdFROM espace_ProfilePropertyWHERE (UserId IN (SELECT CAST(REPLACE(CAST(user1_guid AS VarChar(36)) + CAST(user2_guid AS VarChar(36)), @userGuid, '') AS uniqueidentifier) AS UserId FROM espace_UserConnection WHERE (user1_guid = @userGuid) OR (user2_guid = @userGuid))) AND (UserId IN (SELECT UserId FROM espace_ProfileProperty))
Hi This is probably a very basic question for most people in this group. How do i split the data in a column in to 2 columns? This can be done in access with an update query but in MS SQL server I am not sure. Here is an example of what i want to acheive
Is there a way of changing the value of a column in a view? For example, I have a table with defect code and a description (other columns as well). In a view, I would like to see only the defect code and the description, but if the code is > 90, I would like to define what the description is.
I 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?
SQL 2005 9.00.3402.00 (x64) As Above really when I select * OR select a single column from the view the wrong column data is returned. in SQL Management Studio when I expand the Columns of the view it reflects the old table structure not the new table structure. I can easily fix by compiling the view again but this would mean I would have to recompile all referencing views when I make a change to table structures. I've tried various DBCC Clean Buffers & drop cache with no effect. Is there a command to recompile all views & poss stored procs in a database. Any help or explanation would be appreciated GW
Hi, I am stumped and was hoping someone could help me out. Any help isappreciated.I have a view that looks sort of like this (but with a lot moreentries of course)UniqueIdentifyierColumn1Column21 9999 1002 9999 2003 9999 300What I want to do is to add a column to the view that will contain alist of the values from column 2 where column 1 is the same.UniqueIdentifyierColumn1Column2Column31 9999100100, 200, 3002 9999200 100, 200, 3003 9999300100, 200, 300
If a Select is done on a column whose data type is nvarchar(16) and contains only numerals (UPC numbers) the select does not return the record.
1. Query with numerals in nvarchar column works as long as multiple records are returned (LIKE '012%') 2. Numeric (INT only one tested) columns works as expected 3. String columns with alpha data works as expected 4. Problem only exist when running in Device Emulator and/or actual device. 5. Same test on desktop app runs as expected. 6. Windows Mobile 6, Vista Ultimate 7. Same results when when connection to device from SSMS 8. SQL Servers comes on
Previous thread discussion of this problem (I thought that Parameters corrected problem, but not in all cases???)
In Report Builder 1.0 you could drag a column to a filter and see the data before select the values for the filter.I can't find a way to do that in report builder 3.0. is it possible to see the data of a column in Report builder or SSRS?
I'm working on a script to merge multiple columns(30) into a single column separated by a semicolons, but I'm getting the following error below. I tried to convert to the correct value. but I'm still getting an error.
Error: "Conversion failed when converting the varchar value ';' to data type tinyint".
I am dealing with what I believe is Oracle that is the source of a SQL View.
I am seeing a data type of Integer in the View, but I am not able to see what makes up that View. When I query the View, I can see that an Integer data type column is storing a blank space. I use ISNUMERIC(ColumnName) = 0 and there are a lot of rows that show as a zero length blank space, or text, or something. I just know that it is not an Integer.
I have attempted to CAST and Convert this value, but it will not. I have changed the data type on the table that is being inserted in too, and it still fails with a Conversion error. I have tried REPLACE(), but still the same conversion error.
The report runs but I get a "#ERROR" when I place the field on the report.
I next tried creating a new column with the SQL statement:
SELECT Project.ProjectCode AS PC, Project.StatusCode AS SC, Time.StandardHours AS Hours, Time.StandardChargeAmt AS StdAmt, Time.TaskUID as UID, Time.StandardChargeRate as Rate, ChargeableFlag, 'Bill' =
Case When TaskRule.ChargeableFlag = 0 Then 'Non-Bill' When TaskRule.ChargeableFlag = 1 Then 'Billable'
[Code] .....
This query, less the case statement for BLAmt creates the dataset for the SSRS. Adding the Case statement for the BLAmt produces the error: "Invalid column name 'Negamt'."
Can anyone assist me with a script that adds a new column to a table then inserts new values into the new column based on the Table below. i have included an explanation of what the script should do.

I have 2 tables in a database. Table 1 is Parts and Table 2 is MiniParts. I need a script that adds a new column in the MiniParts table. and then populate the new column (NewMinipartsCL) based on Values that exist in the PartsNum column in the Parts Table, and MiniPartsCL column in the MiniParts columns.
The new column is NewMiniPartsCL. The table above shows the values that the new column (NewMiniPartsCL) should contain.
For Example Anytime you have "1" in the PartsNum column of the Parts Table and the MiniPartsCL column of the MiniParts Table has a "K" , the NewMiniPartsCL column in the MiniParts Table should be populated with "DK" ( as shown in the table above).
Anytime you have "1" in the PartsNum column of the Parts Table and the MiniPartsCL column of the MiniParts Table has a "K" , the NewMiniPartsCL column in the MiniParts Table should be populated with "K" ( as shown in the table above). etc..
I want to create a table. One of the columns should be in the data type MONEY with two digits on the right side of the decimal point. How is that possible?
I have a table with Million plus records. Due to Running Totals article, I have been able to calculate the Trial_Balance for all months.
Now I am trying to provide a Beginning Balance for all months and the Logic is the Beginning Balance of July would be the Trial_Balance of June. I need to be able to do this for multiple account types. So the two datasets that need to be included in logic is actindx and Calendar_Month.
For actindx of 2 and Calendar_Month of 2014-01-01The Trial_Balance_Debit is 19585.46 This would make the Beginning_Balance of actindx 2 and Calendar_Month of 2014-02-01 19585.46
I am trying to do some type of self join, but not sure how to include each actindx number differently.
Table creation and data insert is below.
SET ANSI_NULLS ON GO
SET QUOTED_IDENTIFIER ON GO
SET ANSI_PADDING ON GO
CREATE TABLE [dbo].[TrialBalance]( [Trial_Balance_ID] [int] IDENTITY(1,1) NOT NULL,
