SQL For Field Names From A Table
Oct 6, 2005
Hi,
We have a database with some tables with (what I would
denote as) 'referred field names'.
Like this:
DataTable1 with fields F1, F2, F3
DataTable2 with fields F3, F4, F5
DataTable3 with fields F1, F5, F2
We also have a table with field names
FieldNameTable with fields FIELD, NAME
containing data like:
FIELD NAME
----------------
F1 FieldName1
F2 FieldName2
F3 FieldName3
F4 FieldName4
F5 FieldName5
Now, we need a way to query the data of these tables, but
the result of the query should show the 'referred field names'
from the FieldNameTable.
For example, querying DataTable3 should produce the output
FieldName1 FieldName5 FieldName2
------------------------------------------
... ... ...
... ... ...
Any idea how (and whether) this can be done with an SQL query?
Thanks in advance for tips & tricks.

I'm trying to do an update query that looks like this:
UPDATE
PAEMPLOYEE
SET PAEMPLOYEE.LOCAT_CODE = EMPLOYEE.PROCESS_LEVEL
FROM
PAEMPLOYEE A
JOIN EMPLOYEE B ON A.EMPLOYEE = B.EMPLOYEE
It's erroring out on the Employee prefix B.EMPLOYEE saying:
..."does not match with a table name or alias name used in the query"
Is it wrong or will it cause problems to have a field name the same as the table name?

Hi,
How canI get all field names in a table using sql query? Now I am not interested in the data in this table, what I am interested in is just the schema, i.e. all field names. Thanks.

Hello All.
You may find below script stupid to you. I am trying to create a table with week number that is not fixed, i.e. March 2006 may have 4 weeks and April 5 weeks based on our company calendar.
And Field Names could be Grp, SubGrp, Week_10, Week_11, Week_12, Week_13 depending on the week being stored in TempWeekFile. We could start the month having only Week 10 and following week with Week 11 added into TempWeekFile.
My below script shows error. I have following records in my TempWeekFile
Week_No WeekCnt
10 1
11 2
12 3
13 4
How to write a script that do the above? Has anyone done this using a better method? Please advise. Thank you.
---------------------------------------------------------
if exists (select * from information_schema.tables where table_name='WeeklySalesToThird_Month')
drop table WeeklySalesToThird_Month
Declare @WeekCount int
Declare @Cnt int
Declare @WeekNo varchar(2)
Select @WeekCount = count(*) from TempWeekFile
Select @WeekCount
Select @Cnt=1
CREATE TABLE [dbo].[WeeklySalesToThird_Work_Month] (
[Grp] [varchar] (30) NULL ,
[SubGrp] [varchar] (30) NULL ,
while @Cnt<=@WeekCount
Begin
select @WeekNo = Week_No from TempWeekFile
where WeekCnt=@Cnt
[Week_@WeekNo] [Money] NULL
@Cnt=@Cnt+1
End
) ON [PRIMARY]
GO

I am designing a package to export staging tables into a flat file.The names of the tables will be: TableAStaging_YYYYMM and TableBStaging_YYYYMM. As you can see the names of the tables will be changing each month.
The flat files will have similar naming: C:MyPathFlatFileTableAStaging__YYYYMM and C:MyPathFlatFileTableAStaging__YYYYMM.I want to run the package as an sql job in two steps, one for each table.I need to dynamically pass the table names and file names (together with the path) to the IS package.

Hi
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
Thanks.

Is there anyway to determine what the resulting Field Names are going to be from a SQL Statement?
For example:
SELECT TABLE1.FIELD1, TABLE1.FIELD2, TABLE1.FIELD3, TABLE2.FIELD1 AS ANOTHERNAME
FROM TABLE1 INNER JOIN TABLE2 ON TABLE1.PK = TABLE2.FK
resulting field names:
FIELD1
FIELD2
FIELD3
ANOTHERNAME
Seems easy enough splitting all values before "FROM" by comma and doing some manipulation to remove table names and anything before the word "AS". However, it gets more difficult when you have complex CASE statements embedded in you query that may also contain commas.
Just a shot in the dark because I don't know if anyone has already done something like this before.
Thank you in advance,
Jeff

Howdy all,I'm wishing to write a stored proc to return only the field names from a table. What I've tried gets the field names but also returns all of the data in each row. I only want the field names. Is this possible?Thanks!JP

I can't seem to find a sample code, either here or on the net - - so I'll go ahead and ask...
What I'm looking for is a sample of how to query a database, so that I can populate a listbox with the table names from a database - - and then, populate another listobx with the field names from the database, in order to build a user-driven sql statement builder....
either of the above (at least the field name part) - either a code sample, or a link, will be greatly appreciated) - -
Thanks

Hi,
is there any "robust" way to find out the name of a field in the pipeline by it's Lineage ID programatically? There is a sample code out there (on one of the blogs) but it seams not to be reliable...
The usecase is easy... What is the field name in an error output of that column that causes the error? We don't want to have hardcoded LineageIDs in the error handling so I think it's the best idea to go with field names... However we only get that LineageID...
Thanks,

While creating a view in SQl Server 2005 Management Studio Or Interation Services on a SQL Server 2000 database using "*" something very strange happens. Has anyone every seen this happen before?
The new view is created something like the following:
CREATE VIEW [dbo].[new_view]
AS
SELECT *
FROM Table1
GO
However, when right-clicking on the new view, and choosing "Design", the SELECT scrambles the field names with aliases of the other field names. When the view is run, the result set is incorrect. It may look something like the following:
SELECT
Field1,
Field2 AS Field3,
Field3 AS Field4,
Field4 AS Field5,
.
.
.
From Table1
GO

Hello All,
I have been trying to get this code work, but I could not. Every thing seems going well. However, The result of running the sql query is strange. It shows the field names twice.
Eg:) if you have a table called "newtable" that has two fields[Custnumber, Custname], you will get somthing like this [Custnumber, Custname Custnumber, Custname]. I have tried many times, but I couldn't fix it.
Sub Page_Load(sender As Object, e As EventArgs) handles Mybase.Load
if not page.Ispostback then
try
Sqlconnection = New Sqlconnection (connectionString)
querystring = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNs
WHERE TABLE_NAME = 'Newtable'"
SqlCommand = New SqlCommand(queryString, Sqlconnection)
SqlConnection.Open
dataReader = SqlCommand.ExecuteReader(CommandBehavior.CloseConnection)
while dataReader.Read()
Tablefields_txt.text += dataReader.Getstring(0) & ", "
End while
catch ex as Exception
msgbox("An error has occured: " + ex.Message,0, "Error Message")
finally
SqlConnection.Close()
End try
End if
Any help , please

I am in a situation where I need to find out unique field names with different values in a table having 200+ columns.
Let's say I have two rows with 200+ columns ( I exported these rows from Lotus Notes to SQL Server) I am not sure what columns makes unique of these rows. It's going to be tedious by checking each column values.
Is there anyway I can write a squl query on these two rows which outputs column names which are having unique values.
I would appreciate If anybody gives me hint about achieving desired result

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?

Hi,I have a C# web app that searches my database table using thefollowing search parametersSearch string, criteria (< =) and the field you want to perform yoursearch on. My understanding is that stored procedure is the way to go.What's the best way of doing this using stored procedures. Can Idefine a placeholder for the field name?Ex.SELECT field1, field2... FROM Table WHERE field1='value1' where field1and value1 are both sent from code.If it's not possible then what is the best way to approach thisproblem? I see so many searches like that on the internet. I can onlydo them with inline SQL and not stored procedure.Thank youMaz.

I have a .NET program that can connect to either an Access 97 database or anSQL Server 7 database. In the database I have two tables which have a fieldcalled ID. When I run a query like "SELECT A.*, B.* FROM A, B", the queryreturns those fields as "A.ID" and "B.ID" when connected to Access 97, butas "ID" and "ID" in SQL Server 7. Is there anyway to get SQL Server toprepend the table name to the field name in a case like this and not returnduplicate field names like that without having to specify aliases for thefields?- Don

I am importing a file creating by an application which exports the file into .dbf format. Very unfortunately, this .dbf file can have fields with IDENTICAL column_names. Utilizing ActiveX, I create an ado connection to the .dbf file using a visual foxpro drver. However, and not unexpectantly, I can not do the 'select *' from the file if there are duplicate names.
Can anyone make recommendations here that might help?
Oh, this is SQL200 in case that impacts what you might advise!!!!

have a field in a table that has combined lastname,firstname and middle name like
combs,albert mike
woods-athere,jane alice
The last and first name are separated by a comma, and the middle name by a space
I need in tsql to split them to last name,first name and middle name
I used below
select substring (longname, 1, patindex( '%,%' , longname) -1 ) 'firstname',
substring (longname, patindex( '%,%', longname) + 1, len(longname)) 'lastname',
substring (longname, patindex( '% %', longname) + 1, len(longname)) 'middlename'
FROM Demographic_staging
I get the names all split, but I get the middle name with the first name. How can I limit the first name to recoginze the comma, but stop at the space

I need to migrate data from one sql database to another. The second DBis a newer version of the "old" database with mostly the same tablesand fieldnames. In order support some reporting queries in the "new"version I needed to change the datatype of a few fields from varchar toint(the data stored was integers already as they were lookup tables).DTS works great except in the cases of about 10 fields which I changedthe datatypes on from varchar to int.DTS seems to drop the data if the fieldname and datatype are not anexact match. Is there any way to use DTS and have it copy data from afield call subsid type varchar to a field call subsid type int?

So I have an MDX query in an SSRS data set. Here is my MDX query:
Code SnippetSELECT { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, { ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
This query returns 4 fields. Media Property, Promo Code Description, Gross Sales, and Net Sales. For the given query the measures are empty or null. I do not want any data to show up when the measures are null so I put in NON EMPTY clauses before the COLUMNS and before the ROWS. So now my query looks like this: (I only added the NON EMPTY clauses)
Code Snippet
SELECT NON EMPTY { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, NON EMPTY{ ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
Adding the NON EMPTY returns nothing... not even field names. This is a problem because, I have a table in the report that looks at this data set and when there are no fields, the report can't run.
How can I still have NON EMPTY functionality and still show the fields? Is this a problem in SSRS?

Any help here would be greatly appreciated...
Unfortunately, data wasn't filtered prior to getting inserted into this table. Now I am stuck with cleaning it up. I have thought about writing a query to update all the values, but there are just too many variations, including spelling mistakes, so I've ruled that out as a possible solution.
I have a table which has a Country field but the values per record vary. For example US, U.S., USA, United States, UK, United Kingdom, Canada, Can, etc. I'm trying to find the percent of records per country.
Sample table data: mytable
Id Name Country
1 John US
2 James UK
3 Jane United States
4 Mary Canada
5 Jack U.S.
6 Tony United Kingdom
7 Jeff US
8 Tom Canada
9 Beth UK
10 Mark USA
I would like to show
US: 50% --> (includes any variation of US ncluding US, U.S., USA, United States)
UK: 30%
CAN: 20%
I've made several attempts myself with no luck. Thanks in advance.

ALTER FUNCTION [dbo].[ReplaceTags](@XML VARCHAR(MAX))
RETURNS VARCHAR(MAX)

BEGIN

for example, if the XML input data is the following: It consists of: BANKP, BCJA, BCJAM, BFTH, BFTH, and EMPOP.But the updated function is only recognizing two of names BFTH, BFTH, as hyperlinks, from the database_tags table.Is there a way to get the function to recognize more than one names as hyperlinks.
