How To Identify The Base Table For A PageID ?

Jul 19, 2007

Hi,

Have a LOB error which provides the corrupt PageID and this recommends a DBCC CHECKDB. However I'm unable to identify what the base table for the PageID. DBCC PAGE does not provide base table info (I think), DBCC PGLINKAGE has been retired in SS2005 and DBCC READPAGE doesn't work either.

Does any know of a valid SS2005 command or technique which will allow my to identify the base table for a PageID???

Get A Max Value From One Table Base On Date From Another.

Jul 20, 2006

I have a problem where I need to join multiple tables. Part of the query needs me to make the following relationship in a join.

Say I have a table with items, prices, and dates.

PriceTable

ITEM PRICE DATE

A 1.00 5/5/2000

B 3.00 1/1/2000

A 2.50 6/5/2004

....

This table represents an items price from the date on. So Item 'A' costed 1.00 from 5/5/2000 through 6/5/2004, then it costed 2.50 from that day on.

Now say I have a table of transactions with items, amount bought, and dates.

TransactionTable

ITEM AMOUNT DATE

A 5 6/6/2003

A 1 8/5/2003

A 2 8/5/2004

The total for A should come out to be 11.00. There are multiple Items and multiple price changes.

If someone could point out how a inner join of this nature would work it will help me in my query. I guess the reason i say inner join is because I am joining multiple other tables to do my query.



My current Price Table has a start date and an end date and my query looks something like this. "Select SUM(PriceTable.Price * TransactionTable.Amount) From PriceTable Inner Join TransactionTable ON TransactionTable.Date Between PriceTable.StartDate and PriceTable.EndDate AND PriceTable.Item = TransactionTable.Item".



I want something like this because the tables need to be in the format above "Select SUM(PriceTable.Price * TransactionTable.Amount) From PriceTable INNER JOIN TransactionTable ON Max(PriceTable.Date) WHERE PriceTable.Date <= TransactionTable.Date AND PriceTable.Item = TransactionTable.Item".

Hope that made sense, thanks.

How Can I Search A Schema To Identify Table

Feb 12, 2007

I am trying to find a needle in a haystack.

One of the tables in this database has a column named column_xyz.

There are over 800 tables, each with numerous columns. If I know that the column I am looking for is "column_xyz" is there an easy query I can do to identify all tables that contain that column?

I hope.

Thanks

Truth Table Generator For Any Base!

Jul 25, 2007

This little handy algorithm provides a truth table for any range of numbers between 0 and 65535 of any base between 2 and 36!
As a twist, you can either return the digits concatenated or as separate columns.CREATE PROCEDURE dbo.uspTruthTable
(
@FromNumber SMALLINT = 0,

@Step INT = 1,
@Base TINYINT = 2,
@Concat BIT = 0
)
AS

SET NOCOUNT ON

DECLARE @Temp INT,
@SQL VARCHAR(8000),
@b VARCHAR(12),
@d VARCHAR(2),
@Diff INT,
@Digits CHAR(36)

IF @FromNumber > @ToNumber
SELECT@Temp = @FromNumber,
@FromNumber = @ToNumber,
@ToNumber = @Temp

IF @FromNumber < 0
BEGIN
RAISERROR('The parameter FromNumber %d is less than 0 (base 10).', 16, 1, @FromNumber)
RETURN
END

IF @ToNumber > 65535
BEGIN
RAISERROR('The parameter ToNumber %d is greater than 65535 (base 10).', 16, 1, @ToNumber)
RETURN
END

IF @Base < 2

END

SELECT@SQL = '',
@Temp = FLOOR(LOG(@ToNumber) / LOG(@Base)),
@Diff = @ToNumber - @FromNumber + 1,
@Digits = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'

WHILE @Temp >=0

Identify Range And Related Data From Look Up Table

Dec 27, 2007

I have a query/report that I need to create that needs to look at the size of a company and based on that size apply different rules. I am sure that this is not the only query/report I'll need to do using this and I'm also not so sure that the size ranges won't be changed in the future. Given this, I'd like to store the size ranges in a lookup(global) table. That way, if the ranges ever change I can just alter them in that table and not in all of the queries/reports that use them. What I need to figure out is how to join the live table with the look up table.

Specifically, here is what I have. The look up table would be:




Code Block
CREATE TABLE #gl_sizerange (
glsid int IDENTITY(1,1) NOT NULL,
lowsize int,
highsize int,
sizecat varchar(10),
milestone varchar(25),
days int
) ON [PRIMARY]
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Approach', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Interview', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(1, 24, 'Small', 'Close', 7)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Approach', 14)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Interview', 21)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(25, 99, 'Medium', 'Close', 7)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Approach', 14)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Interview', 21)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Demonstrate', 21)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Negotiate', 14)
INSERT into #gl_sizerange VALUES(100, 499, 'Large', 'Close', 7)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Approach', 28)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Interview', 35)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Demonstrate', 28)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Negotiate', 35)
INSERT into #gl_sizerange VALUES(500, 300000000, 'Super', 'Close', 35)




Then what I have is two more tables, one that indicates the size of the company and another that has the milestone contained within it and I will also calculate how long that milestone has been open and if it is longer than what is in the lookup table for that milestone and size range I need it returned in the report. Here are some quick sample table to represent that data (I've condensed the size and number of tables for the example):




Code Block
CREATE TABLE #en_entity (
enid int NOT NULL,
orgsize int,
) ON [PRIMARY]

INSERT into #en_entity VALUES(1, 5)
INSERT into #en_entity VALUES(2, 18)
INSERT into #en_entity VALUES(3, 24)
INSERT into #en_entity VALUES(4, 25)
INSERT into #en_entity VALUES(5, 47)
INSERT into #en_entity VALUES(6, 101)
INSERT into #en_entity VALUES(7, 499)
INSERT into #en_entity VALUES(8, 500)
INSERT into #en_entity VALUES(9, 10000)
INSERT into #en_entity VALUES(10, 567890)
CREATE TABLE #op_opportunity (
opid int NOT NULL,
enid int NOT NULL,
milestone varchar(25),
daysopen int
) ON [PRIMARY]
INSERT into #op_opportunity VALUES(1, 1, 'Approach', 5)
INSERT into #op_opportunity VALUES(2, 2, 'Interview', 18)
INSERT into #op_opportunity VALUES(3, 4, 'Negotiate', 24)
INSERT into #op_opportunity VALUES(4, 7, 'Demonstrate', 25)
INSERT into #op_opportunity VALUES(5, 7, 'Approach', 7)
INSERT into #op_opportunity VALUES(6, 9, 'Close', 35)
INSERT into #op_opportunity VALUES(7, 8, 'Close', 36)






So, given the sample data, I would expect the results to return me the following opids from the #op_opportunity table because they don't comply with what is in the look up table based on milestone, size and days open: 2,3,4,7

Insufficient Base Table Information For Updating Or Refreshing

Nov 16, 2006

I am using MADC 2.8 to connect to Sql Sever 2000.

The Connection string uses a File DSN.

I get few records into a Record set using Select Command. Then I update one Col in the Recordset and Updates the database table. I open the recordset in

I am getting "Insufficient base table information for updating or refreshing" Error some times. This Code executes in a Multi user Environment.

I tried to recreate this error condition on my local system by Deleteing/Updating the Reocrds from the table and even locking the table.

I get this error "Row cannot be located for updating. Some values may have been changed since it was last read."

Are both of these errors connected? or is there any way i can get rid of this error



The Code is somethng like this

Set objRs = New ADODB.Recordset
objRs.CursorLocation = adUseClient
objRs.Open strSql, SQLCON, adOpenDynamic, adLockOptimistic
If (Not objRs.BOF) And (Not objRs.EOF) Then
objRs.Fields("FLAG") = 1
objRs.Update
VAR1 = objRs.Fields("0")
Else
MsgBox ("No Reocrds exist")
End If


Thanks in Advance for any help

Row-level Security: Permissions Required On Base Table?

Jun 2, 2007

I'm implementing row-level security in a SQL Server database that uses Microsoft Access for the front end. I'm using a UDF (a view behaves the same way) to restrict access to specific rows of a base table based on membership in a role. According to the reading I've done, if the base table has DENY ALL permissions for the role, and the UDF has GRANT ALL, members of the role should be able to update records in the base table via the UDF, without having direct access to the base table. However, I find that unless I grant appropriate permissions on the base table, the user is unable to update the table via the UDF.



Is this expected behavior? Nothing I've read suggests I should have to grant permissions on the columns of the base table.

SQL Server 2014 :: Trigger On A View If Any Insert / Update Occurs On Base Table Level

Apr 21, 2015

I have a situation where I have Table A, Table B.

View C is created by joining table A and table B.

I have written a instead of trigger D on view C.

I do not insert/update/delete on the view directly.

For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.

And I am unable to see this trigger work on the view if any insert/update occurs on base table level.

Trigger is working only if any operation is done directly on the view.

SQL Server 2012 :: Identify Sets That Have Same Items (where Set ID And Items In Same Table)

SHOWCONTIG - Need A Bit Of Help To Identify If

Greetings.

I'm currently on a company with an ms sql server 2000. I'm looking into the indexes and tables to see if there are some bottlenecks there but the LogicalFramentation is very low in the index I have searched.

However, this table has a logicalFragmentation of 99,9215698242188 which I get when I do DBCC SHOWCONTIG ([TInsurance]) WITH TABLERESULTS. Is that a value to be trusted or not to be trusted since this does not check an index? If it is, how do I defrag a table? I know only how to defrag an index. (example: DBCC INDEXDEFRAG (MFSSEK,[TInsurance], PK_InsuranceID) )

How To Identify An Array

Nov 20, 2006

I have seen several examples explaining the fact that a tablecontaining a field for each day of the week is for the most part anarray. An specific example is where data representing worked hours isstored in a table.CREATE TABLE [hoursWorked] ([id] [int] NOT NULL ,[location_id] [tinyint] NOT NULL,[sunday] [int] NULL ,[monday] [int] NULL ,[tuesday] [int] NULL ,[wednesday] [int] NULL ,[thursday] [int] NULL ,[friday] [int] NULL ,[saturday] [int] NULL)I had to work with a table with a similar structure about 7 years agoand I remember that writing code against the table was pretty close toHell on earth.I am now looking at a table that is similar in nature - but different.CREATE TABLE [blah] ([concat_1_id] [int] NOT NULL ,[concat_2_id] [int] NOT NULL ,[code_1] [varchar] (30) NOT NULL ,[code_2] [varchar] (20) NULL ,[code_3] [varchar] (20) NULL ,[some_flg] [char] (1) NOT NULL) ON [PRIMARY]The value for code_2 and code_3 will be dependently null and they willrepresent similar data in both records (i.e. the value "abc" can existin both fields) . For example if code_2 contains data then code_3 willprobably not contain data.I do not think that this is an array. But with so many rows wherecode_2 and code_3 will be NULL something just does not feel right.I will appreciate your input.
