I have a task to where I need to move a column from one table to
another. I want to be sure I update any view, stored procedure,
trigger, etc. that references the column. I simply want a query that
will report the related objects and then I will update them manually
but before I go and try and figure out how to do this by querying the
sys tables is there an sp_sproc that will do this?
I'm pretty new with SSIS. I have written some custom component which will read from flat file and write it into database. Between those processes, there are other processes which will analyse and transform the data being transfered. Everytime, I remove a column from upstream component, I have to go through each component to fix up column reference mapping using Invalid Column References Editor. There are lots of clicking involves just to remove a column from upstream component. My package has about 15 components. I am just wondering, is there anyway for us to prevent that editor to pop up, instead fixing invalid column reference programatically in ReInitializeMetadata?
I am in the process of converting Oracle package into SQL Server Stored procedure. I could not find SQL SERVER counter part for the oracle's ratio_to_report function.Using the conventional SQL with Subquery is Adversely affecting the perforamance. can any one help me ?
I'm using SQL 2005 Server Management Studio - I go to the Northwind database - new query window and paste this code, I just found on this forum, to find the Identity column:SELECT C.name AS Colname, UPPER(U.name) AS Coltype, C.status AS Cstatus, C.ColId, C.Id AS Cid, C.length, C.xprec, C.xscale FROM syscolumns C JOIN sys.tables O ON C.id = O.object_id JOIN systypes U ON C.xusertype = U.xusertype WHERE O.name = 'Fred' AND C.status = 128 ORDER BY C.colid SELECT C.name AS Colname, UPPER(U.name) AS Coltype, C.status AS Cstatus, C.ColId, C.Id AS Cid, C.length, C.xprec, C.xscale FROM syscolumns C JOIN sys.tables O ON C.id = O.object_id JOIN systypes U ON C.xusertype = U.xusertype WHERE O.name = 'Products' AND C.status = 128 ORDER BY C.colid However, I get an error message saying:Invalid object name 'sys.tables'. What might I be missing here?
Hi,I'm having trouble running the following query:select * from message where text_body like ' ----------%'ie, five spaces followed by at least ten hyphens. The query doesn'tcomplete, so eventually I cancel it. If I remove the hyphens from thequery ("... like ' %'") then it runs fine (though it doesn't findthe correct data).Am I confusing SQL Server by using a wildcard or regular expression?(I'm using SQL Server 2000 - 8.99.760).Thanks in advance for any helpRichard
Not sure if this can be done, but you are a clever bunch. I am looking for a way (preferably through a stored procedure) to return the original column name for an aliased cloumn. For example, I have a table view like:
"SELECT id, firstname, lastname, qty as Amount FROM tblTeam"
Returned columns are id, firstname, lastname, Amount. I would like to look up the results returned by the view, and get a list of the ORIGINATING columns (eg. id, firstname, lastname, qty) from the returned data. I am using php script to run stored proc. Thanks.
I have a table. In that table I have a list by student number that lists the entry dates into a particular grade. When trying to list only the first time entered, there is no unique way to identify one row from another other than the date. Is there a way to use max or min to only pull one date per student number? I have done a series of case when statements and I am able to get it down to 1 to 2 entries per student number, but I need to get it down to only 1 date per student number.
Thank you for your help
SELECT DISTINCT mx.stu_num,
CASE WHEN er.STU_NUM = ep.STU_NUM
ELSE CASE WHEN ea.STU_NUM = ep.STU_NUM
ELSE CASE WHEN eb.STU_NUM = ep.STU_NUM
END AS entrydate
FROM dbo.mx AS mx LEFT OUTER JOIN
dbo.v_EntryDate9_R AS er ON mx.stu_num = er.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_P AS ep ON mx.stu_num = ep.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_A AS ea ON mx.stu_num = ea.stu_num LEFT OUTER JOIN
dbo.v_EntryDate9_B AS eb ON mx.stu_num = eb.stu_num
I always seem to come back to dataset issues. Nonetheless, here is my problem:
I am retrieving data using a stored procedure that lists the number of bookings per hour and the revenue that generates also per hour. So, you enter a single date in the stored procedure, for example 2001-10-01 and it will bring back 24 rows corresponding to the 24 hours (obviously) and two columns, one displaying the number of bookings and one displaying how much revenue.
Pretty simple so far.
I have a report using SQL Reporting Services that allows users to enter two dates and therefore you get two tables with the relevant dates data. For example, table one has date 1's data and table 2 has as you'd expect date 2's data. Both tables use different datasets.
The reason why I am using different tables and different datasets is that the stored procedure I use only allows the use of one date at a time therefore, I use a second dataset to generate the second date's data.
The problem occurs when I want to calculate a difference between the two date's data, for example have another table that shows the differrence between table one and table two for bookings for each corresponding hour.
Anyone have any ideas as to how I could achieve this?
I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
I have a table that stores part numbers and manufactuers. Somehow this table has become corrupt showing different manufacturers with the same part numbers.
I know this will take a bit of manual digging to fix, but I want to find a way to pull all rows that have the same part number that have different manufacturers, or just pull up any "duplicate" part numbers and I can determine what is right or wrong as far as the manufactuers and make those changes.
I have tried this, but it does not seem to want to work.
Select * from my_table Where partnumber = (select partnumber from my_table) and compName <> (select compName from my_table)
I have tried other variations of the same, but nothing seems to want to show me just the items that have the same part numnbers and different manufacturers. I do not care if there are duplicates of the same part number/manufacturer entries, just if the part number is duplicated where the manufacturers are not the same.
These are the rows I want to edit and group by part number. I have almost a million rows of entries and this is not something I want to go through row by row. :-P
Example data CA1000 CA10001 CA10002 CA10003 CA11597 CA11603 CA1001 CA998 CA999 As you can see, CA11603 is the largest number in this list. When I try the follow sql code, SELECT MAX([MyCode]) FROM [MyTable] WHERE (SUBSTRING([MyCode], 1, 2) = 'CA') The largest number comes back as CA997 When I try MAX([MyCode]) FROM [MyTable] WHERE [MyCode] LIKE 'CA%' The largest number comes back as CA997
SELECT TOP 1 (SchoolMasterCode) FROM SchoolMaster WHERE (SUBSTRING(SchoolMasterCode, 1, 2) = 'CA') ORDER BY Schoolmastercode The largest comes back as CA10001 When I try.... SELECT TOP 1 (SchoolMasterCode) FROM SchoolMaster WHERE (SUBSTRING(SchoolMasterCode, 1, 2) = 'CA') The largest comes back as CA1278 What am I doing wrong?
Does anyone have a TSQL utility (that they can share) that recursively searchs sysobjects for a matching input parameter string(for instance column name) for stored procedure object properties that returns the stored procedure name?
I've got a rowset (intermediate result in a large query) that's equivalent to this table:
create table T (
K bigint, V bigint, W tinyint, primary key(K,W) )
What I want is "for each K, find the V associated with the largest W". Or,
select K,V from T t1 where W = (select max(W) from T t2 where t2.K = t1.K)
What I'd like is a solution that does not involve a self-join on the table (which the sub-query effectively is). The rowset can be sorted by (K asc, W desc), in which case I'm looking for the first (K,V) pair for each unique value of K.
In the larger query, T could have 100's of thousands of rows, and as I mentioned, T is the result of another query on my base tables. I can express T as a CTE easily enough, but the resulting query plan (using the sub-select, as above) ends up performing the query that generated T repeatedly in order to implement the self join.
I can save T into a temp table - in fact, that's what I'm doing now - but I'd rather avoid using a temp table if possible. This query needs to be of the highest possible performance, so if there's a no-temp-table, no-self-join solution, I'm all ears!
I could imagine making a CLR UDF that does the filtering that I want, but I'm not convinced that it'd be a good choice - any insights on whether that's worth trying would be appreciated as well.
Normally, you establish referential integrity so that foreign key in one table points to a primary in another. Here is a composite key:
(A_ref, B_ref) => (A, B)
Consider a situation where A is a primary key in table T1. It is refered by T2, which has A,B as it's prmary key. An example of this situation would be a table of printers and table of batches a printer has printed at specific date. The batches are identified by Printer, Date, BatchNo within the date. Now, we create a temporary table T3, which addresses "today" batches. The "today" reference is taken from a date is taken from some record in the DB and, combined with the Printer ID and BatchNo, must point to a record in T2. Is it possible to specify such a complex relationship to ensure the referential integrity?
The advantages of the integirty are:
-- the referred records are pinned down from removal -- it is not possible to refer unexisting object; thus, the referee is ensured to refer an existing one.
Hi, I'm doing a web application that will get some information from an ERP. At this moment I have 2 databases: 1) The aspnetdb, where I have the tables for Merbership and Role 2) The ERP database I need to put my web application tables on one of these two DB's. This tables will reference the users from the membership and some products from the ERP DB. I will store products requests that will store both UserID (from aspnetdb) and ProductID (from ERP DB). I'm thinking to put these tables on the aspnetdb, so that all web application tables stick together. But, I will loose tha ability to make joins with the ERP database, right? Do you think this will work? Can someone make some comments about this situation, and give me some tips? Thank you!
Hi All - I have come across the need to use a cube in AS 2005 for an application. Unfortunately this will be the first time writting an ASP.Net application which uses one. I was wondering if any of you had any good books or references that I could look at to get an idea of how I should approach this issue. Thanks in advance.
HelloSuppose a database Db1 with tables tl1 and tl2 and a second database db2with tables tl3 et tl4.Is it possible to make a join between tables of the two databases ?As for example, Select * from tl1 INNER JOIN tl3 where tl1.Field1 =tl3.Field3Thank for any helpThierry
I am currently developing a stored procedure that includes a number of computed fields. Is it possible to reference a computed value, (eg. FLdA), or do I need to CREATE a temp file and then reference the FldA and FldB values. I have simplified my code, it is much more extensive in that there are numerous WHEN clauses attached to each FldA and FldB computation.
SELECT FldA = CASE WHEN .... THEN CurQty * 1.5 WHEN .... THEN CurQty * 1.75 ELSE 0 END), FldB = CASE ..... NewValue = CASE WHEN .... THEN FldA * CurValue WHEN .... THEN FldB * CurValue etc.
I have a data list that will grow over time. The values are listed vertically in a column; most recent value at the bottom. I am trying to figure out how to setup a formula to figure out the standard deviation on the most recent 30 values automatically. For instance if the column contains 30 values and I add the 31st value, I'd like to have to have the standard deviation displayed in a cell and automatically shift from calculating on values 1-30 to values 2-31. Is this possible?
I'm trying to create some tables in my database but I'm getting some errors... The one which is causing the most trouble is Msg 1767, Level 16, State 0, Line 38 Foreign key 'ten_fk' references invalid table 'Tenant'. I'm not sure why it's complaining... can anyone help me out here?
