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!
Is there anyway to check for cross-database dependencies?
For example:
I have a stored proc in the Pubs database that contains a query that references a table in the Northwind database (as well as reference a table in the Pubs database.) I'm having no problems finding the depencency for the Pubs table. I can't seem to find the dependency for the Northwind table.
Any help would be appreciated.
Thanks in advance.

Hi,I have over 200 stored procedures and they have dependencies on each other (not necessarily a cyclic dependency).Is there a way in SQL Server 2005 that I can disable a dependency check while I am executing a script that creates those stored procedures, and then re-enable it after?Thanks.

I have 2 tables, different designs, different number of rows, I simply need to check whether the contents of a column in the first table is in a column in the second table, just simply a table/column to table/column data check for the same data content.
Easy Peasy for you guys, any help would be appreciated.
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.
I have a table column can save english(single byte) or chinese(double byte) char, how to distinguish the records containing chinese(double byte) char thru sql command
thx.
I am trying
IF OBJECT_ID(''tempdb..#tempTable.Column'') IS NOT NULL
But its returning me a null every time. Is there any other way to check if column exists in temporary table.
Hello all,
I am trying to add columns to several tables in a singular database. I want to check to see if the column exists in a given table first before executing the alter table command so that I can skip that command if the column already exists, and avoid aborting my script prematurely. I can't seem to find a way to check for the column's existance. Any suggestions?
Table ATable B
AIDBID
Col 1BCol1
Col 2
Col3
I want to put a check constraint on A.col3 that depends on the values of A.Col1, A.Col2 and B.BCol1
How can I achieve this without using function.
I have been having trouble with enabling table dependencies using the aspnet_regsql utility on the Product table in the AdventureWorks database. It is in the Production in the normal dbo schema. When I run the utility to enable the table dependency for SQL cache notifications it fails because it tries to prefix the reference to the table with dbo.Now I know it just adds a trigger for INSERT, UPDATE and DELETE where it runs a stored procedure to update the main table dependency table, but if I do that manually it requires that the trigger also run in the Production schema. I am not sure if this will still work with SQL query notifications.http://msdn2.microsoft.com/en-us/library/ms124719.aspx Please reply if you can help.

Hi
I am creating a report on a database where some of the table names start
with the @ sign - ie @table1.
Reporting services picks this up as a parameter, instead of a table name in
my query, even though I am encapsulating the table name in square brackets
eg. [@table1]
I have several data sets in the report that i am using to populate valid
parameters. These datasets are all variations of queries from tables that
have @ as the first character.
When i then try to run the report i get an error message as follows:
"The report parameter pool has a default value or a valid value that depends
on the report parameter SD_POOLCONTRACTS. Forward dependencies are not valid"
This is frustrating as SD_POOLCONTRACTS is not a report parameter but one of
the database tables that has @ for it's first character.
here is the query that i use to obtain the valid values for the pool report
parameter that i am trying to set up.
SELECT distinct u_poolcode as Pool
FROM OCRD INNER JOIN
OCRG ON OCRD.GroupCode = OCRG.GroupCode INNER JOIN
CRD1 ON OCRD.CardCode = CRD1.CardCode inner JOIN
[@SD_POOLCONTRACT] INNER JOIN
[@SD_POOLCONTRCT_LINE] ON [@SD_POOLCONTRACT].DocEntry
= [@SD_POOLCONTRCT_LINE].DocEntry INNER JOIN
[@SD_CONTRACTS] ON [@SD_POOLCONTRCT_LINE].U_DocNo =
[@SD_CONTRACTS].DocNum ON
case when len(ocrd.fathercard) = 0 then ocrd.cardcode
else ISNULL(OCRD.FatherCard, OCRD.CardCode) end = [@SD_CONTRACTS].U_CardCode
WHERE (OCRD.CardType = 'c') AND (OCRG.GroupName LIKE N'producer%') AND
(CRD1.AdresType = 'b')
ORDER BY OCRG.GroupName, FatherCard, OCRD.CardCode
Any help would be appreciated.
I'm currently stuck with a table that has 350 mil records. Querying this table is insanely slow so I had a better look at existing yearly partitioning. I already managed to partition on a month level which increased the performance/querrying a lot. I did this on the staging table where I used an alter statement to split the 2015 partition by 12 months.
However, in our project we used Data Vault. This means that we have 4 tables (hub, sathub, link, satlink), all carrying 350 mil records. The problem is that altering the partition function does not work. The server cannot handle this action. What the best way is to do this, without having to drop/reload all tables.
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,

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
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.
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'.
Here's an example of the script that I'm using:
CREATE TABLE Session (
session_key char(18) NOT NULL,
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?
I have the table:
CREATE TABLE Mytable(
mykey integer,
mycol integer
CHECK(mycol BETWEEN 1 AND 2)
PRIMARY KEY(mykey))
How do I change the constraint to
CHECK(mycol BETWEEN 0 AND 2)
...without losing any data?
Thanks!

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

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.
