How To Alter Column Length Of The Master Table Along With The Slave Table?
Aug 13, 2006In SQL Server 2005,here are two tables, created by the following SQL Statements:
CREATE TABLE student(
ID CHAR(6) PRIMARY KEY,
NAME VARCHAR(10),
AGE INT
);
CREATE TABLE score(
ID CHAR(6) PRIMARY KEY,
SCORE INT,
FOREIGN KEY(ID) REFERENCES student(ID)
);
For the length of Column ID is not enough, So I want to alter its length.The alter statement is:
ALTER TABLE student ALTER COLUMN ID CHAR(20)
For the table student is referenced by table score, the alter statement can not alter the column of the table student, and the SQL Server DBMS give the errors.
But, I can manually alter the length of the column ID in SQL SERVER Management Studio. How to alter column length of the master table(student) along with the slave table(score)?
Thanks!
T-SQL (SS2K8) :: Procedure Parameter Length Declaration Less Than Column Length?
Jun 30, 2014is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
BlobColumn.GetBlobData() With Data Length &&> Integer Length (32767)
Mar 27, 2008For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,

Determine Last Access Of A Database Or Table
Dec 18, 2007Does anybody know of a way to determine the last date/time a table has been accessed (query/update)? I've done enough research to know that this isn't easy. However, perhaps somebody has figured out a way through some of the stats that SQL Server keeps to determine the last access of a table. I have recently been put on a team that had no DBA and has a number of databases out there. They would like to determine which databases are inactive and get rid of them. I am a developer and haven't had much SQL Server Administration experience. Any info will help greatly! Thanks!

Determine Row Of Data In A Table Through SSIS
Jun 13, 2013I have a requirement based on 2 parts to determine a row of data in a table through SSIS :
a. Work out the LEG_SEQ_NBR of the VESSEL, VOYAGE and LEG already stored in table1.
To do this join table1 and join table2 through BL_ID column.
b. Work out the 2ndVESSEL, 2ndVOYAGE and 2ndLEG.
Once we have identified the LEG_SEQ_NBR of the VESSEL,VOYAGE, LEG already stored in table1 we need to add '1' to this value and then find that LEQ_SEQ_NBR in table2.
The DDL of table1 and table2 along with the test data are as below:
CREATE TABLE [dbo].[table1](
[BL_ID] [decimal](10, 0) NOT NULL,
[VESSEL] [nvarchar](10) NULL,
[VOYAGE] [nvarchar](12) NULL,
[LEG] [nchar](3) NULL,
[Code] ....
For Example:
BLNO = 21 and BL_ID = 1
Current Vessel/Voyage/Leg in table1 = CEUR 032E E
LEG_SEQ_NBR of this Vessel/Voyage/Leg in table1 = '1'
Therefore if we add '1' to this value we'd be looking for LEG_SEQ_NBR '2' as the 2ndVESSEL,2ndVOYAGE,2ndLEG.
In this case that would = MARB 794S S
How this can be worked out through an SSIS job ?

Determine Current Table Of Trigger
May 6, 2008Good Morning
Is There anyway to determine the table you are referencing in a trigger's inserted / deleted tables?
i.e would this be possible
print @Table_Name + " was Updated"
Where @Table_Name is the table on which the trigger is created
(bad example I know but you get the idea)
Any input will be appreciated.

May 5, 2008Hi 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?
Thanks,

SQLserver 2005 -data Length 'max'
Jan 11, 2007Hi all,
I ve few queries regarding SQLServer 2005, kindly help me to understand the things,
1. Datatypes like nvarchar, varchar, varbinary use 'max' to define their datalength,
a. is this 'max' always has the value of 2^31-1 ?
b. what other data types in sqlserver 2005 can use 'max' to define their datalength?
2. I defined a table (say 't') with a column 'name' of datatype nvarchar(max), now tried to execute the below query in the SQLServer client,
select column_name, data_type, character_maximum_length from information_schema.columns where table_name='t'
the result is,
+--------------+------------+--------------------------+
| column_name | data_type | character_maximum_length |
+--------------+------------+--------------------------+
| name | nvarchar | -1 |
+--------------+------------+--------------------------+
The question is why the datatype length is returned as -1, what happened to 'max'?
is there any other way to retrieve the actual data length (ie., 'max') from the table definition?

SP To Determine Layout, Population And Sample Data In Table(s)
Nov 1, 2007Hi! I am new to SQL Server... looking for some veteran assistance.
"Data Integrity Report"
I need a Stored Procedure that takes a table name as a parameter and returns a cursor suitable as a data source for a pre-built Report Services report (I guess Report Services would call the SP?).
The cursor/report needs to have the following columns:
Ordinal_Position (I.E. Column number)
Column_Name
Number Of Blank Rows (how many missing values for this column in this table)
Difference (Between total rowcount and population of this column)
Data_Type
Column_Length (either Character_Maximum_Length or the numeric widths rolled up with COALESCE?)
Sample Data (The contents of the "first" row in the table, based on a TOP(1) and ORDER BY xxx)
The report should look like this (for a table with 100 rows):
Col Num Col Name # Blanks Difference Data Type Col Length Sample Data
1 Name 12 88 varchar 30 Sally Smith
2 Address 34 66 varchar 45 123 Main St Apt 45
3 Acct_ID 0 100 varchar 4 AB12345
Using the "Information_Schema.Columns" I can get everything I need except for #3 (blanks count) and #7 (Sample data).
Is it possible to do this as 1 query, with a CTE or APPLY or something, or do I need to do a table variable based on the Information_Schema and then use dynamic SQL and row-by-row COUNT(*) for each column? And the same for the Sample Data.
Sorry for the long post, and thanks in advance!

CommandParameters.length Don't Match Parametervalues.length
Feb 24, 2008I am trying to narrow down this problem. Basically, I added 3 columns to my article table. It holds the article id, article text, author and so on. I tested my program before adding the additional field to the program. The program works fine and I can add an article, and edit the same article even though it skips over the 3 new fields in the database. It just puts nulls into those columns.So, now I have added one of the column names I added in the database to the code. I changed my businesslogic article.vb code and the addarticle.aspx, as well as the New article area in the addartivle.aspx.vb page. The form now has an additional textbox field for the ShortDesc which is a short description of the article. This is the problem now: The command parameters.length is 9 and there are 10 parameter values. Right in the middle of the 10 values is the #4 value which I inserted into the code. It says Nothing when I hover my mouse over the code after my program throws the exception in 17 below. Why is command parameters.length set to 9 instead of 10? Why isn't it reading the information for value 4 like all the other values and placing it's value there and calculating 10 instead of 9? Where are these set in the program? Sounds to me like they are hard coded in someplace and I need to change them to match everything else. 1 ' This method assigns an array of values to an array of SqlParameters.2 ' Parameters:3 ' -commandParameters - array of SqlParameters to be assigned values4 ' -array of objects holding the values to be assigned5 Private Overloads Shared Sub AssignParameterValues(ByVal commandParameters() As SqlParameter, ByVal parameterValues() As Object)6 7 Dim i As Integer8 Dim j As Integer9 10 If (commandParameters Is Nothing) AndAlso (parameterValues Is Nothing) Then11 ' Do nothing if we get no data12 Return13 End If14 15 ' We must have the same number of values as we pave parameters to put them in16 If commandParameters.Length <> parameterValues.Length Then17 Throw New ArgumentException("Parameter count does not match Parameter Value count.") 18 End If19 20 ' Value array21 j = commandParameters.Length - 122 For i = 0 To j23 ' If the current array value derives from IDbDataParameter, then assign its Value property24 If TypeOf parameterValues(i) Is IDbDataParameter Then25 Dim paramInstance As IDbDataParameter = CType(parameterValues(i), IDbDataParameter)26 If (paramInstance.Value Is Nothing) Then27 commandParameters(i).Value = DBNull.Value28 Else29 commandParameters(i).Value = paramInstance.Value30 End If31 ElseIf (parameterValues(i) Is Nothing) Then32 commandParameters(i).Value = DBNull.Value33 Else34 commandParameters(i).Value = parameterValues(i)35 End If36 Next37 End Sub ' AssignParameterValues38 39 40 41

View 1 Replies View RelatedHow To Determine Cause Of Timeout?
Aug 3, 1999Good day,
We have a web application (ASP) running on SQL Server 7.0.
Recently, the users are getting quite a lot of timeouts on
the database:
Microsoft OLE DB Provider for ODBC Drivers error '80040e31'
[Microsoft][ODBC SQL Server Driver]Timeout expired
The database is not supposed to be doing too much work, so I can't
understand why these timeouts are occuring. How can I determine
the cause of the timeouts?
The cause could probably anything from a trigger that's taking
too long, a query that's taking too long, or simply bad database design.
I've looked at SQL Server's Profiler, but could not yet use it
successfully to give me any hints of what could cause the timeouts.
Any ideas of how I can use Profiler, Performance Monitor, or any other
tool(s) to see what is happening in the background in the database,
i.e. how much processing a trigger is using, etc.
Thanks very much!
