How To Determine Table And Column Names In A Trigger?
May 5, 2008
Hi all,
I'm new to this whole trigger 'thing', so forgive me if this question has been asked and answered a few times already.
I'm in the process of writing a trigger that will send an e-mail to an application admin when any table within a given database is altered (IE, a column is added or deleted). I can get the e-mail to fire off when that happens without any issue, but I'd like to be able to let the admin know which table was tweaked and what new column was added.
Is this a relatively easy thing to do and I'm just not finding the right built-in variable name, or does something more need to be done?
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.
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
Hi all, By using below query i can get no of tables having the give column name in a particular database, SELECT COUNT(*) AS CounterFROM syscolumnsWHERE (name = 'empno') but i want to know the table names too? any one please suggest me how to find table names too...... In other words i know the particular column name and right now i want to know the table names in which this column name exists.
I was wondering how would I get the column names from a table? Not the results just a listing of column names. What is the command to get this information? I am using MS Access, but I posted here because MS SQL is the closest thing on this forum and the syntax is usually similar.
All, is there a way of getting all table names that contain a columnname?I'm looking at a DB that has 125+ tables and I'm interested in findingall table names that contain the column order_date.How can I do it?TIA,Sashi
I wasn't sure whether or not to post this in the .NET or MsSQL forum, mods please move accordingly.
Say I have two tables: Store, and Area that have the following columns: Area: AreaID, AreaName, Description
Store: StoreID, AreaID, StoreName, Description
When I run the following query : SELECT * FROM Area, Store WHERE Area.AreaID = Store.AreaID, the following columns come back from the .NET SQLDataReader
Even though the Description fields are different there is no differentiation between which one is which (other than an integer index)
Is there a way to form the SQL query so the columns come back Area.AreaID, Area.AreaName, Area.Description etc...
I was hoping to do something like the following Select Area.* as 'Area.'.* ...
but that wasn't liked by the SQL server, any ideas?
Note: The actual tables are more complex than this, and the table names aren't static. Individually aliasing columns won't work, nor will checking the alias.
I would like to list all the column names against each record of the table and and would like to keep track whether the column is empty or nonempty. How can I write SQL query for this?
I am using the following to extract the column names of a table. I would like to do this for the whole database. Currently I am cutting the results into an excel spread. Is there a better way of doing this? Here is the query
SELECT name FROM syscolumns WHERE [id] = OBJECT_ID('tablename')
SELECT TOP 100 text, query_plan, cp.plan_handle, qs.last_execution_time FROM sys.dm_exec_cached_plans cp CROSS APPLY sys.dm_exec_sql_text(cp.plan_handle) CROSS APPLY sys.dm_exec_query_plan(cp.plan_handle) JOIN sys.dm_exec_query_stats qs ON cp.plan_handle = qs.plan_handle WHERE objtype='Adhoc'
I have below output:
Text Query_plan Plan_handle Lst_execution_time Select id,name from person <Showplan... dshkkgdaHqrqe13232423 2015-07-21 10:50:22.713 Update customer set Cid=3 where name='abc' <Showplan... poasfvrqe13232423 2015-07-21 10:16:22.500 delete from orders where ORid=8 <Showplan... 2ase2423 2015-07-21 10:10:22.710 Select 1,2,3,4,5 from num <showplan afqfqfq 2015-07-21 10:10:22.710

I would like to use variables to set the table name and some column names of a SQL Query in a stored procedure (the variable values will come from a webpage)... something like this:ALTER PROCEDURE dbo.usp_SelectWorkHours @DayName varchar,@DayIDName varchar AS BEGINSELECT @DayName.InTime1, @DayName.OutTime1, @DayName.InTime2, @DayName.OutTime2 FROM @DayName INNER JOINWorkHours ON @DayName.@DayIDName = @DayName.@DayIDName INNER JOINEmployees ON WorkHours.WorkHoursID = Employees.WorkHoursID END RETURN ...is this possible?? if so how? Thanks
Hi, I have a SP which returns a select query on a temp table so I get to choose column names when I create the #table.
Can I determine column names myself based on the results of another query (in the SP) before, or (preferably) after I create the #table and populate it.
My query is used to bind to a datagrid so I could use....
dataGrid.Columns[index].HeaderText and set it to a particular output parameter, but I want to keep the code in the SQL.
HiI have been working since 2 days to device a method to export sql tableinto csv format. I have tried using bcp with format option to keep thecolumn names but I'm unable to transfer the file with column names. andalso I'm having problems on columns having decimal data.Can any one suggest me how to automate data transfer(by using SP) andretaining column names.ThanksNoor
Hi all,A (possibly dumb) question, but I've had no luck finding a definitiveanswer to it. Suppose I have two tables, Employees and Employers, whichboth have a column named "Id":Employees-Id-FirstName-LastName-SSNetc.Employers-Id-Name-Addressetc.and now I perform the following join:SELECT Employees.*, Employers.*FROM Employees LEFT JOIN Employers ON (Employees.Id=Employers.Id)The result-set will contain two "Id" columns, so SQL Server willdisambiguate them; one column will still be called "Id", while theother will be called "Id1." My question is, how are you supposed toknow which "Id" column belongs to which table? My intuition tells me,and limited testing seems to indicate, that it depends on the order inwhich the table names show up in the query, so that in the aboveexample, "Id" would refer to Employees.Id, while "Id1" would refer toEmployers.Id. Is this order guaranteed?Also, why does SQL Server use such a IMO brain-damaged technique tohandle column name conflicts? In MS Access, it's much morestraightforward; after executing the above query, you can use"Employees.Id" and "Employers.Id" (and more generally,"TableNameOrTableAlias.ColumnName") to refer to the specific "Id"column you want, instead of "Id" and "Id1" -- the"just-tack-on-a-number" strategy is slightly annoying when dealing withcomplex queries.--Mike S
I tried with the following and result is coming for one month i.e. JUL but not with the second Month i.e Jun
SELECT 'Jul1' AS MON, [BNQ], [FNB], [RS] FROM (SELECT REVENUECODE, SUM(ROUND(((Jul/31)*30),0)) AS JUL FROM RM_USERBUDGETTBL WHERE USERNAME='rahul' AND FY=2015 GROUP BY REVENUECODE, USERNAME ) AS SourceTable PIVOT (SUM(JUL) FOR REVENUECODE IN ([BNQ], [FNB], [RS])) AS PivotTable
I have a SQL text column from SP_who2 in table #SqlStatement:
like 1row shown below :
"update Panel set PanelValue=7286 where PanelFirmwareID=4 and PanelSettingID=9004000"
I want to find what table and column names are in the text ..
I tried like below ..
Select B.Statement from #sp_who2 A LEFT JOIN #SqlStatement B ON A.spid = B.spid where B.Statement IN ( SELECT T.name, C.name FROM sys.tables T JOIN sys.columns C ON T.object_id=C.object_id WHERE T.type='U' )
Something like this : find the column names and tables name
I got a table which gets populated by stor proc where we pivot the Sum(Balance of mortgage) by YYYYMM for the whole duration of the loan term.
I have a requirement to rename the column header where the previous month end balance period be renamed to P0.
if we run the report today, then the balance as at 31/09 should show under column P0 which now shows under 201509 and then P0 keeps shifting with each month run.
I'm trying to write an SSIS package that exports a table that has changing column names to an excel file. The column names change due to the fact that the table is created by a pivot daily. the only thing I'm missing is the ability to dynamically map the tables' columns to the excel destination. Is this possible?
I read in another thread that "It is not possible to create packages or new objects within packages using SSIS." I also read in the books online that "The input and the input columns of the Excel destination have no custom properties." To me this means that I cannot programmatically create or remove columns in the excel destination. Please tell me I'm wrong. So, to summarize my research so far. In writing an SSIS package, I cannot programmatically create a new excel destination object and I can't manipulate an existing one. I hope I'm wrong. Can anyone help me? (and please correct any wrong assumptions I may have stated)
In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable SET [columName] = (SELECT SUM(columName) FROM RegularTable WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?
I want to update Flag column in second table based on the Adder names.
If the Applicatiion has atleast one AIX and Adder name is UDB then the flag would be True. If the Application has more the one AIX and Adder names are diferent then the flag would be null.
APpName OS Adder
App1 ||| Windows|||Null App1 ||| Linux |||UDB App1 ||| AIX |||UDB App1 ||| Linux |||Sql
I thought I saw this done once before. So today I hunted around inBooks OnLine and did a Google search. So far I have found nothingclose. So if you know how to do it, please tell me or if cannot bedone, I'd appreciate know that too.Thanks in advance,IanO

I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:
select [uplift specialty], [member po],[practice unit name], [final nomination status] ,[final uplift status], [final rank], [final uplift percentage] ,practiceID=row_number() over (partition by [practice unit name] order by Metricname) ,metricname,Metricvalue, metricpercentilerank
[code]....
Rheumatology Table:The columns that vary start with "GDR" and [GDR Percentile Rank] so I'm just showing those:
I am trying a create views that would join 2 tables:
Table 1: Has all the columns need by a view ( Name: Product Structure: ID, Attribute 1, Attribute 2, Attribute 3, Attribute 4, Attribute 5 etc Table 2: Is a lookup table that provides the names of columns Name: lookupTable Structure: tableName, ColumnName, columnValue Values: Product, Attribute1, Color Product, Attribute2, Size Product, Attribute3, Flavor Product, Attribute4, Shape
