Hi,
Is it possible to change any fieldname of an existing table?I mean to say
by TSQL statement.We know that we can alter the data type and width etc.
But I haven't got any info about filedname change.So if it is possible
Please help...
And Is there any TSQL command to alter multiple columns in a single statement?
I have some huge tables (think 200+GB for a single table) which are excellent candidates for sparse columns. The tables have many columns which are defined with decimal datatypes (13,2) with a large percentage of them (over 50% in most cases- some as much as 99%) being 0.00. Since this is very expensive in terms of storage my idea is to set all the 0.00 values equal to NULL then set them as sparse. Across 100 or so identical databases, I have 5 such tables, with 20-40 columns in each table.
1.) three steps for each column in each table in each db.
Step 1: update table to allow for nulls
Step 2: update tabe set column=null where column =0.00
Step 3 update table set sparse columns
2.)
Step 1: Create entirely new table with sparse column definitions
Step 2: copy entire table, transforming 0.00 to null for affected columns via SSIS
Step 3: drop original table, rename new table to original name
I want to add a computed field to an existing SQL table: where Field1 is >0 and field2 is not null set newfield = 'Y' else set newfield = 'N'
I want to keep this existing table because I'm using it as the basis for an Access Report that is nearly complete.
BTW this table is the result of a DTS package that is comprised of several SQL executables so I need to be able to repeat this as part of a larger process.
Hi, I have the lovely task of overhauling some of our SQL-based systems. I've found many tables that don't have unique identifying numbers that really should have them. I've searched around and people keep mentioning the Identity field as being similar to Autonumber in Access. The only examples I could find involved setting up a new table... but I need to add (and populate) an identity column to an existing database table. Does anyone know the command for this?
Example... my table is called PACountyTown. It currently has 3 columns: County, Town, and Area. I wish to call the identity-ish field RecordID.
Greetings:I have a SQL 2000 database, in which about 1% of the records are inlower case. I need to make them UPPER CASE.Is there a function to determine and change the case of existingrecords, or will I have to re-write the records manually?Thanks,DW
I must increase column (filed) size in existing datebase but without usingEnterprise manager....(Becouse we use MSDE on our clients PCs)The Filed is part of primary and foreign key constraints....And every constraint has diferent index number in each database...for example (PK_something_9e382hjl8), and I don't know how to pick thisvalue before "drop constraint" command.....Thank you very much....
We had existing cubes in our Analysis Server, we were required to move them on another Reporting Server which would be using Data Replicated every night to that server. Problem is now source data is divided into 2 Reporting Database Servers. Table Names/View Names are the same in all the Databases. I just want to change the data source pointing to existing Database to the new Reporting Server. Can you tell me how this can be achieved?
Hi! I want to add a word to a value if the value already exists in that field. How to do this? Please help me. In detail, i have 'id', 'name' and 'info' three columns in one Data Table. When I inserted one value to id field, if the value already exists it should add a word to that value and it should get inserted. Please help me to do this? Thanks in advance!
I'm developing a report in RS 2000 that uses two datasets. The first dataset provides data to a drill-down report on the top part of the screen and the second small dataset provides some data for additional summary information on the bottom of the screen. I'm getting a runtime error "An unexpected error occurred in Report Processing. The expression referenced a non-existing field in the fields collection." Of course, I've edited every expression I can think of: text boxes, data grid, parameters, filters, drill-down lists... I think I've gone through every object on the report but I can't isolate the bad expression. Can anyone suggest a better way to debug this type of error? It compiles fine, but fails in runtime. thanks.
I have a field on my SRS Report called directioncode. This field gives me a value of 1 or 0.
How do I fix this code so if the value of directioncode is 0, the text "Incoming" is displayed if the value of directioncode is 1, the text "Outgoing" is displayed?
Current value in the expression area of my field.... =Fields!directioncode.Value
I have a field where all of the data is 5 characters in length. The last character denotes a status and will always be an F, H, or T. I want to add a new field (which I will do manually) and populate the new field with the last character from the "old" field. Once that is complete, I want to eliminate that 5th character from the old field.
Hi all: I need to change the year to many records that, by mistake, were put with a 2007 date, but they should be still with 2006, can anyone help me ?
I use Sql Server 2000 and the field is of type datetime
This is a followup to my last post. If a field name is changed in the database, what is the easiest way to determine what stored procedures and triggers that reference that field are now broken?
How can I change a field type whilst it is populated?
I have tried :
insert new_table select * from old_table
but I get :
Disallowed implicit conversion from datatype 'text' to datatype 'varchar' Table: 'davy.dbo.new_table', Column: 'de_area' Use the CONVERT function to run this query.
My table formats are as follows :
TABLE dbo.new_table ( de_pk int NOT NULL , de_name char (25) NOT NULL , de_area char(255) NULL )
TABLE dbo.new_table ( de_pk int NOT NULL , de_name char (25) NOT NULL , de_area text(16) NULL )
We have a small table of about 13 million rows that needs altered. A column in the table needs to be changed from a varchar(20) to a varchar(500). When we ran the alter table script, 3 hrs later and it wasn't done running. Any suggestions on what we can do to speed up the process?
Thanks ahead of time DMW
Edit: We are running SQL Server 2000 and the db at the time was running in simple mood
SQL 2000 Enterprise Manager won’t let me drop a unique key index and move it to another field. I get an error regarding ‘drop index not allowed because of unique key constraint enforcement.
Is there anyway to change fields for unique keys in SQL Enterprise Manager?
I import a flat file from a legacy system, and then convert it into a single table. That works simply enough.
Then I have a SP that querys that table using a parameter for an accountID. My business tier calls that SP and returns the results to the calling tier (my web application). Easy enough...
Now for the question. The people who created the flat file (written in COBOL) decided to use "codes" to represent data. So, for instance, if I'm looking for the account plan, I can expect to see characters like ], or [, or +, etc... These characters have a special meaning, like:
] = Plan A [ = Plan B + = Plan C, and so on.
Currently, the web application displays those characters, but I want it to display the actual plan name. Is there a way that when I execute the SP, the SP could pull the necessary records, and whenever it encounters a certain "plan" character, it could convert it into a "readable" name? Say that it sees that the plan_type field has a value of "]" for twenty records, so it converts those twenty records' plan_type value from "]" into "Plan A"? I'm not sure if I can do that, but I want to at least evaluate the option if I can.
I've evaluated other options, like using a CASE statement in my code, but I shot that down quickly...for obvious reasons. I don't wanna be changing my web application or business tier each time these guys update a plan name, or add a new one, delete an existing one, etc...
I've also thought about creating a dictionary table than contains the plan's code and its name, and then just INNER JOIN the first table with the dict table. This would keep my SP very simple (it's very straight-forward right now, and I like that). That way, if a plan name is ever changed, or a new one is added, I simply update the dict table using a simple query. However, if my SP is doing the conversion, I could just as easily update the SP.
Either of these methods would work for me, and I *do* know how to do the latter (dict table). However, there are quite a few other fields that I may have to do this for. I believe when I left for the day on Friday, my last count was 14 fields total that needed translation. That would mean 14 different dict tables! That could certainly affect my SP performance with all those INNER JOINS!
Therefore, I'm certainly interested in figuring out if it's possible to do the former method (SP), and then I shall decide which method is best for my situation.
Feel free to include your thoughts on which process you think is better as well. I'm really riding the fence with this one. However, if I can't find out how to change field values in my SP, then obviously I'll make a decision very quickly...
Why is it that when you change a field name is SQL Server it sometimes completely messes things up. I renamed a field in one of my tables from Emp# to EmpNumber. I had a view based on this table and naturally I knew I would have to change a view I had based on the table. I opened the view and changed the field from Emp# to EmpNumber but when I tried to open the view I got an error “Invalid column Name EMP#”. I have not been able to fix this. I have dropped and recreated the view, refreshed all the objects using enterprise manager, refreshed all the objects using Query Analyzer, shut down and restarted my computer, taken my database offline and put it back on line. The field name EMP# is not in any tables in my database and not referenced any views or procs . I am just starting on this database so I could verify this very easily because I only have a few views and procs.
Has anyone had this problem or more importantly does anyone know why this is happening or how to fix it?
I have two databases that are merged using replication, and I want to change the length of one of the fields. Can anyone think of a way of doing it that doesn't require dropping the whole publication and rebuilding it? Thanks Ed
the basic pattern is... a user has approvers, and those approvers have approvers as well... i have 4 columns of approvers.. and if my first approver is the manager, then my second approver will be the managers approver and my third approver will be the managers approver's approver and so on..
on my actual page, i have select fields for the app, app2, app3, app4 and i need it so that when i change the very first app, it'll automatically update app2, app3, and app4
any ideas how i would do this? im pretty new to sql but im thinking i would use some type of join?
Hi Everyone,I have a question about dynamically changing the length of a varchar(n)field, in case the value I'm trying to insert is too big and will givea "truncated" error, but before the error is given! i.e. Is there somekind of a way to "test" the length of the field while Inserting thevalue into it, and to have it automatically increase its length to thelength of the value being inserted, in case the value is too big?I've been able to do this in a "primitive" way, simply by identifyingthe specific error number in case the value is being truncated, andthen increasing the length of the varchar(n) field by using the ALTERcommand, and then duplicating the insert statement, but is there astandard (shorter) way of doing this?Here is my code (I'm working in an ASP environment):<%var_txt = "abcdefghijklmnopqrstuvwxyz12345678789"sql = "Insert Into Table1 (text) Values ('" & var_txt & "')"On Error Resume Nextconn.Execute sqlIf err = -2147217833 ThenResponse.Write "Error Recognized Successfully!<br /><br />"sql = "ALTER TABLE Table1 ALTER COLUMN text VARCHAR(" &Len(var_txt) &") NOT NULL"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "Error while trying to alter Column:<br/>" & err & "= " & err.description & "<br />"ElseResponse.Write "Column altered successfully to: " &Len(var_txt) &"<br />"sql = "Insert Into Table1 (text) Values ('" & var_txt &"')"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "<br />Error number 2:<br />" &err.description &"<br />"ElseResponse.Write "Now it was added successfully!HaHa!<br />"End IfEnd IfElseResponse.Write "Success."End If%>Thanks in advance!
Hello, I am working on a project that involves one part where a field's value needs to be changed when the user updates the record. Here is the situation in detail: There is an InputData table where the user enters new records or changes existing records. There is a field called "calculated" in this table which has a default value of 'no'. A stored procedure runs math calculations on all the InputData records where the calculated field = 'no'. At the end of this stored procedure, it sets the calculated field = 'yes'. When new records are added by the user their "calculated" field value is 'no' by default so that the next time the stored procedure is executed, it only runs the math calculations on the new records. The problem is, if a user changes an existing record, the "calculated" field needs to be changed from 'yes' to 'no' so that the stored procedure recalculates the math for the modified record. How do I change the value from 'yes' to 'no' on records that the user modifies? Thanks.
Hi guys, I need to get a column with the sum of the field "SUF" from table "JurnalTransMoves_1" when that field ("SUF") is ordered by the field "REFERENCE" from table "Stock", and Show the value only once.
The desired result should by something like:
Stock.REFERENCE JurnalTransMoves.SUF SUM(JurnalTransMoves.SUF) Group By Stock.REFERENCE
5752 10 60
5752 20
5752 30
5753 400 3000
5753 500
5753 600
5753 700
5753 800
5754 7 15
5754 8
Is there any chance to do that? Thanks in advance, Aldo.

If I have a column named "Login" in a SQL Table (I am sharing with another application) that I am using a stored procedure to acquire the information from, how can I trranspose its name to match code already written in a Web App to get the data. There is a web app already created that has the followig code to get the data from the database Dim strSQL ast string = "UsersSelectCommand" intLoginID = objDataReader("LoginID")
My stored procedure is the following: CREATE PROCEDURE UsersSelectCommand/* ( @parameter1 datatype = default value, @parameter2 datatype OUTPUT )*/AS Select Lastname, FirstName, Login from Users Order by LastName GO The stored procedure will return "Login" instead of "LoginID" that I am wanting. How can I modify the Stored Procedure to change the LoginID to Login.
I am loading from SQL Server 2008 to Access 2010 using SSIS. One of the columns in the table I am loading into is a Number datatype and Fieldsize is long integer. The values are being truncated, so I want to change the Fieldsize to DOUBLE. Â However, when I do that I receive the error below. What should I do? I would like not to change my Windows registry.
This error can be caused by one of the following:
The maximum number of columns allowed in a table or the maximum number of locks for a single file is exceeded.
The indexed property of a field is changed from Yes (Duplicates OK) to Yes (No Duplicates) when duplicate data exists in the table.
An expression is not specified in the Expression property of a calculated field.Â
If the maximum number of locks per file was exceeded, you can increase the number by editing a registry entry. However, this is not a recommended option.
If you use Registry Editor incorrectly, you could cause serious problems that require you to reinstall the operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Make a backup of the registry. Find the MaxLocksPerFile registry value by using the Windows Registry Editor, and then increase the value. The MaxLocksPerFile value is saved as part of the following key:
If the Indexed property of a field and duplicate data is located in the table, reset the Indexed property to the previous setting, or remove duplicate records from the table.
While I was loading to the same table a few days ago, I received a warning and the task took approx 9 hours. I am attaching the screen shot.
Has anyone seen this issue before? We are running a SQL CE 3.5 database on a windows desktop. A couple of our tables have ntext fields. When we do an insert the statement updates the value for all rows, not just the one that was added. I can easily repro this with some of the online samples too. Try the following:
SqlCeConnection conn = new SqlCeConnection(_sConn);
After the second execution the blob column in both rows will have the value 'Name2 Memo'.
This is obviously a huge problem for us and would appreciate it if someone can explain what is happening. Seems like a bug but would like to be certain before I go the support route.
