Table Names And Field Names

Jan 21, 2004

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?

SQL For Field Names From A Table

Oct 6, 2005

A Strange Problem With SQL Query Fro Getting Field Names

Aug 9, 2004

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

Query Returning Duplicate Field Names

Jul 20, 2005

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.

How To Write A Script To Create A Table (With Unfixed Field Names)?

Mar 28, 2006

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

Transact SQL :: Use Dynamic Table Names And Get Return Value From The Query

Sep 16, 2015

I don't know why this is so difficult. What I want to do is take a table name as a parameter to build a query and get an integer value from the result of the query. But from all of the research I have been doing, Dynamic SQL is bad in SQL server because of SQL Injections. But my users are not going to be supplying the table names.

Things I have learned:

 - SQL Functions cannot use Exec to execute query strings.
 - SQL Functions can return a concatenated string that could be used by a stored procedure to Exec the query string.

So how can I write a stored procedure that will
 
1. take a parameter
2. Pass the parameter to a function that will return a string
3. Execute that string as SQL
4. Get a return value from that SQL statement
5. Then finally, from a View, how can I pass a parameter to the stored procedure and get the returned value from the stored procedure to be used as a field in the View?

Numbers 3, 4, and 5 are where I am really stuck. I guess I don't know the proper syntax and limitations of SQL Server.

Regarding The Query To Save The Ids Of The Edited Names From Different Tables Into A Single Table.

Mar 8, 2008

Here with the below query iam binding my gridview with industry name,company name,Plant Name,Group Name related to the IDs in Audit table.Select Aud.Ad_ID_PK,Aud.Audit_Name,Ind.Industry_Name,Cmp.Company_Name,Pla.Plant_Name,Gr.Groups_Name,Aud.Audit_Started_On,Aud.Audit_Scheduledto,Aud.Audit_Created_On from
Industry Ind,
Company Cmp,
Plant Pla,
Groups Gr,
Audits Audwhere Ind.Ind_Id_PK =Aud.Audit_Industry and
Cmp.Cmp_ID_PK =Aud.Audit_Company and
Pla.Pl_ID_PK =Aud.Audit_Plant and
Gr.G_ID_PK =Aud.Audit_Group and
Ad_ID_PK in (select Ad_ID_PK from Audits)
Now i want to edit these names.
when i click on edit in gridview these names will be filled into textboxes and when i change the names it should compare the name with particular tables and should get the Id of that and store in Audits table.
For example:
i have this data in my audits table:




Commercial83312

2
2
2
1
Here Commercial83312 is ID of that Audit and 2,2,2,1 are the Industry,Company,Plant and group Ids for that particular audit.In the front end i can see the names of this particular IDs.
when i edit the industry name in the UI it must check the name with industry table and get the ID of the changed name and store it in audit table.
so the data may be changed in audits table as :



Commercial83312

4
2
2
1

 




so here the industry ID is changed
I need the stored procedure for this.
please help me,its very urgent...

Using An Exec Query To Insert Pdf, .doc File Into Table From A Dir Path Which Is A Field In Another Table

Aug 5, 2007

I have the following query in sql 2005:


PROCEDURE [dbo].[uspInsert_Blob] (

@fName varchar(60),

@fType char(5),

@fID numeric(18, 0),

@bID char(3),

@fPath nvarchar(60)

)



as

DECLARE @QUERY VARCHAR(2000)

SET @QUERY = "INSERT INTO tblDocTable(FileName, FileType, ImportExportID, BuildingID, Document)

SELECT '"+@fName+"' AS FileName, '"+@fType+"' AS FileType, " + cast(@fID as nvarchar(18)) + " as ImportExportID, '"+@bID+"' AS BuildingID, * FROM OPENROWSET( BULK '" +@fPath+"' ,SINGLE_BLOB)

AS Document"

EXEC (@QUERY)

This puts some values including a pdf or .doc file into a table, tblDocTable.

Is it possible to change this so that I can get the values from a table rather than as parameters. The Query would be in the form of: insert into tblDocTable (a, b, c, d) select a,b,c,d from tblimportExport.

tblImportExport has the path for the document (DocPath) so I would subsitute that field, ie. DocPath, for the @fPath variable.

Otherwise I can see only doing a Fetch next from tblIportExport where I would put every field into a variable and then run this exec query on these. Thus looping thru every row in tblImportExport.

Any ideas how to do this?

Field Names From SQL Statement

Mar 9, 2004

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

Finding Out Field Names By Lineage ID

Apr 26, 2006

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,

Scrambled Field Names In Views

Dec 19, 2007

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
