Can you tell me if this is possible? (and how to do it!!)
The application is VS2005, with sql database.
I want to check if a specific column exists in a specific table in the database and if not then add it, all via my application.
I'm happy knowing how to connect to the database & pass sql commands (as I'm doing that anyway to set off backups), but not the actual queries I'd need.
I have a pretty standard form that inserts users name, office, and team. It generates a random 10 digit ID for them. How would i got about checking the table to make sure that ID doesn't exist?
Here's my insert code.
string strConnection = ConfigurationManager.ConnectionStrings["TimeAccountingConnectionString"].ConnectionString; SqlConnection myConnection = new SqlConnection(strConnection);
string usercode = GenPassWithCap(9);
String insertCmd = "INSERT into users (ID, firstname, lastname, office, team) values (@id, @firstname, @lastname, @office, @team)"; SqlCommand myCommand = new SqlCommand(insertCmd, myConnection);
myCommand.Parameters.Add(new SqlParameter("@id", SqlDbType.VarChar, 10)); myCommand.Parameters["@id"].Value = usercode;
myCommand.Parameters.Add(new SqlParameter("@firstname", SqlDbType.VarChar, 50)); myCommand.Parameters["@firstname"].Value = txtFirstName.Text;
myCommand.Parameters.Add(new SqlParameter("@lastname", SqlDbType.VarChar, 50)); myCommand.Parameters["@lastname"].Value = txtLastName.Text;
myCommand.Parameters.Add(new SqlParameter("@office", SqlDbType.VarChar, 75)); myCommand.Parameters["@office"].Value = dwnOffice.SelectedValue;
myCommand.Parameters.Add(new SqlParameter("@team", SqlDbType.VarChar, 20)); myCommand.Parameters["@team"].Value = dwnTeam.SelectedValue;
myCommand.Connection.Open();
myCommand.ExecuteNonQuery();
Do I run a completey different select command before hand and try to match that field?
I have two columns.
policyNumber contains a 12-13 varchar string
AllPolicyNumbersIncluded contains one or more 12-13 varchar strings (policy nums) seperated by commas
I want to check if policyNumber is contained in AllPolicyNumbersIncluded?
I have policyNumber LIKE AllPolicyNumbersIncluded which works when only one policy number is in AllPolicyNumbersIncluded and incidently works switched around AllPolicyNumbersIncluded LIKE policyNumber I assume because they are equal.
Can anyone tell me how to check if one column's value is a substring of another - without going through every possible substring of the second
How can I test to see if a column exists before adding a column to a sql mobile table?
thanks,
Luis
I have 3 tables - Data, Facility and FacilityKey
The FacilityKey table will hold the Data ID and Facility ID based on a series of check boxes on a form.
My question is what is the best way to do the insert into the FacilityKey table from the form? If 5 facilities are checked I don't want to do 5 separate calls to the database for inserts, but I'm a bit confused on what the best method would be.
Thank you!
I need help thinking about this problem :-)
I have an SSIS pkg that automatically downloads financial extracts from an ftp site. Once the files are downloaded, I load the extract to a table. The table is first deleted before the insert, so that each time the table has "fresh" data (whatever was in the extract for that day).
Once the extract data is in the table, I load the data into yet another table that combines data from many tables. Simple enough.
Problem is, sometimes when I download the extract, it hasn't been updated yet, so I'm downloading an OLD extract. This old data then gets loaded into the first table. That's ok, because it doesn't really hurt anything. I can always delete the table and reload it if necessary.
The problem occurs when the old data goes from this table into the OTHER table. We don't want old data in this other table!
I need a way to check that I'm not loading the same data 2 days in a row into the OTHER table.
I realize that I might be able to solve this problem without using SSIS, but the solutions I've come up with so far aren't 100% satisfactory. I can use a query to check dates and that sort of thing, but it isn't foolproof, and would create problems if I need to manually force the process though, that is, if I need to override the date logic.
Anyways, I'm wondering if there's an SSIS approach to this problem... I can't rely on timestamps on the data files either. They're not accurate.
This is has been very perplexing to me.
Thanks

I have a table, emailaddresses with an emailaddress field.
before i do an insert from a stored proc, i want to check if the emailaddress is already in the database.
pseudo-code:
if emailaddresssparameter is IN emailaddress then
do not insert
else
insert into table
end
i've got the insert statement and the stored proc, but how do i write the check to see if it's already there? I mean i could do a select * from emailaddress wehre emailaddress=emailaddressparam
but how to i test it? if the count=1 then skip?
here's my proc now:
ALTER PROCEDURE dbo.AddOneEmailAddress
(
@emailAddress varchar(255),
@emailID int=0 OUTPUT
)
AS
/* SET NOCOUNT ON */
insert into EmailAddresses
(email_address)
values
(@emailAddress)
set @emailID=@@identity
RETURN @@identity
I have two tables from two different Databases
DB1.dbo.Table1 and DB2.dbo.Table2
eX:
Table 1
KEY LName FName Updated

1 TIM ABC N
1 PIN ABC N
2 QWE SAD Y
......
....
Table 2
KEY LName FName Updated
1 JIM ABC Y
2 QWE SAM Y
....
....
1) Table 1 and Table 2 are of same structure.
2) In table2, as in above example, few changes have beeen done for KEY1 AND Update =Y, Similarly KEY= 2 AND UPDATED=Y, like for KEY= 1 LName was changed to JIM instead of GYM and for KEY= 2 FName has been changed to SAM instead of SAD.
3) Now I want to do this in SSIS where
a) Its going to process rows of Table2 and check in table1 according to KEY and UPDATE=Y and update the Table1 with Updated = N and Insert that particulra process row of Table2 into Table1
and hence Resultant of Table1 must be like this
Table 1
KEY LName FName Updated
1 GYM ABC N
1 TIM ABC N
1 PIN ABC N
1 JIM ABC Y
2 QWE SAD N
2 QWE SAM Y
......

Can somebody help me how to do this in SSIS. Thnaks a lot in advance

I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country
FROMinserted
OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country
END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------
I use a cursor to handle multiple rows in an update query.

I want to fin out the number of records that are not numeric on my database, how can I fin that using an SQL query?
View 2 Replies View RelatedHello All,
Can someone pls help me with how to check for a numeric value in a varchar column?
For example I have a column called client_id , it has values "AB" , "CD" , "18", "19" . I need to delete those client_id where the values are 18 and 19. How would I do that?
Thanks in advance!!
Can't seem to get my head around this: I'm looking for a way to select only those varchar(10) values that soley consist of numbers. Leading spaces are allowed.
I tried using isnumeric, but it also allows those with periods, comma's etc.
Also tried using like, but the length of the varchar column varies too much to do a like '[0-9][0-9]....'.
As a solution I currently do a combo of isnumeric, not like '%.%', not like '%,%' etc. I need to do a conversion to an int to join another table, but the convert still fails. Not sure where and why.
I'm thinking there should be a better way than create a hughe list of "not like " but it looks like I'm in the woods here...
In a stored procedure I have I have dates in the format YYYYMMDD with symbols representing the first 3 digits
e.g. °30903 =20030903, and I have to convert them to proper dates, and then eliminate all old data, so I replace symbols and then convert to int
SELECT af.AccomType, af.AccomRef, af.AccomName,af.address1, af.address2, bf1.RoomCode,
Convert(Int,Replace(Replace(Replace(Replace(REPLAC E(Replace(MAX(bf1.EndBook),'°','200'),'´','204'),' 99','1999'),'97','1997'),'47',1947),'98','1998')) AS max_date,
...............
WHERE
af.Resort=@strResort
AND
(af.AccomType = 'H' OR af.AccomType = 'O')
AND
max_date>20040721
order by max_date.
Problem is I get an error saying invalid column max_date. It works in the order by clause when I get rid of the
'max_date>20040721 '.
Thanks
I am trying to query multiple columns for a specific value. I have 8 columns (values are either 1 or 0)and I want to query the table to find out which rows contain zero's in ALL of the 8 columns. Whats the best way to do this? I can create a lenghty select statement where column1 =0 and column2 =0 and column3=0 and column4 =0 and column5 =0 .... etc. I was wondering if there was an easier way to do this?
Thanks in Advance

I have 5 to six id columns from my excel input.they can be empty in some cases but of the five columns atleaset one column should have some value....All the five columns should not be empty.
How do i check this scenario...
eg:Input column
ID1 ID2 ID3 ID4 ID5
12 NULL NULL 67 78
I should check to see atleast one column should have some value
How can i achieve this???
Please let me know
Well, actually, as in the title. I have a table. The script should add a column if that column doesn't exist already. I use VB to combine the two queries. So what I want:
Query1: Does the column exists:
if No,
query2: create the column
How can I achieve this?

I receive the following error when creating a CHECK constraint that references another column. According to the good old Wrox SQL Server book, I'm using the correct syntax. Anyone have any ideas???
Thanks in advance!
Server: Msg 8141, Level 16, State 1, Line 1
Column CHECK constraint for column 'end_date' references another column, table 'Session'.

course_key char(18) NOT NULL,
site_key char(18) NOT NULL,
instructor_key char(18) NOT NULL,
start_date smalldatetime NULL,
end_date smalldatetime NULL
CHECK (end_date >= start_date)
)

How do I alter a column check constraint?

CREATE TABLE Mytable(

...without losing any data?

Can anyone please tell me how can i create a uniqueness contraint on part of column and index that part too. i.e.
consider the following table.
table A
Col1
furadfaf
fsradfasd
dddafadsf
hjfhdfjakdj
now i want only left three characters of the Col1 to be unique and indexed.
any idea ??????
say i have a table, and in it are two columns, column1 and column2 and i do the following query:
SELECT column1, column2 FROM table WHERE column2 = '12345'
i want to check if column1 has all the same values, so in the first case, no
column1 column2
------- --------
4 12345
9 12345
5 12345
column1 column2
------- --------
9 12345
9 12345
9 12345
in the 2nd case, column1 contains all the same values, so yes
is there anyway i can check this? i would be doing this in a trigger.. say when a new row is inserted, the value of column1 is inserted, but col 2 is null.. so when they try to fill in the value for col2 of that row, the trigger checks to see if the value they put for col 2 is already in the table.. if it isn't, then everything is ok. but if it is already in teh table, then it checks col1 to see if all the values of col1 are the same
i hope this makes sense
thanks

Hi All,
We have a very convoluted ETL system which is pulling unnecessary data. First thought is to restrict everything so that only the columns/tables that are necessary are brought back. We have a tons of reporting stored procedures that depend on ETL tables, is there anyway we can find out which column/tables these stored procedures are using?
Thanks!
Dear All,
I wanted to know how do I know or check that whether a column exists in a table. What function or method should I use to find out that a column has already exists in a table.
When I run a T-SQL script which i have written does not work. Here is how I have written:
IF Object_ID('ColumnA') IS NOT NULL
ALTER TABLE [dbo].[Table1] DROP COLUMN [ColumnA]
GO
I badly need some help.
How to check to make sure a column does not exist before adding it? Be nice to do this in t-sql code instead of using ado.net. It seems as if the IF NOT EXISTS is not supported in SqlCe 3.1? I am trying to do this but I get the token error:
IF NOT EXISTS (
select *
from Information_SCHEMA.columns
where Table_name='authors' and column_name='NewColumn'
)
select 'no'
Is there a list of all CE supported t-sql commands?
Thanks,
Dan
When generating a check constraint to guarantee that a character column cannot be blank is it best to use comparison operators such as col1 <> '' or to use LEN(col1) > 0? Note that the column in marked as not nullable.
