Append Query To Insert 80000 From One Table To Empty Table

Jul 22, 2012

All, Using access 2003 frontend and sql server 2008 backend. I have an append query to insert 80000 from one table to an empty table. I get an error:

"Microsoft Office Access set 0 field(s) to Null due to a type conversion failure, and didn't add 36000 record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations."

Check If SqlDataSource Is Empty In CodeBehind

Feb 10, 2006

This is probably an easy one.
What is best way to determine if a SqlDataSource is empty (i.e. the query produced no results) in the CodeBehind?
I'm using this:
if (SqlDataSource1.SelectCommand.Contains(String.Empty))
{
      //Add code for scenario here.
}
It seems to work, but something just doesn't feel right about it for some reason.
Thanks

Anyway To Check If A Text Field Is Blank (not Null But Just A Empty String '') ?

Oct 27, 2004

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:


Code:


IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))



Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table

but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"

thanks

Query Or Script To Check Link Table

Mar 23, 2008

i'm pretty familiar w/ mysql, but relatively new to ms sql. Since i can do a lot more w/ ms sql, I have been trying to do all tasks in sql queries or scripts, but i'm stumped on this one. I have a table that links two things together. t1 has rows id1 and id2. When a row has these two id's, there is a "link" between them. I'm trying to make a command or script that will see if there is only 2 links for any given id.

for example, it would loop through each row, and run this command:

SELECT COUNT(*) AS Expr1
FROM links
WHERE (Id1 = this_rows_id1) OR (Id2 = this_rows_id1)

and again w/ id2

and then i would be interested in any row that only had a count of 2. is this possible?

Transact SQL :: Query To Check Properties On A Table When Creating Database?

May 20, 2015

I'm wondering if there is some sql I can run to check properties on a table. This would be used to verify things like data types, allow nulls and default values have been set to avoid mistakes. This could be done manually one table and one column at a time, but it would be a lot easier to look at it in the results window.

Query A Table For A Value In The Code File.

Feb 7, 2008

Ok, so im pretty much finished writing my forum web page.  However to display things like how many replies each thread has and who replied last, i need to perform a query in the code file.  Im guessing its simple enough but i cant get the syntax for actually performing any query.  I already know the sql syntax like select * from all that stuff but how do i get do something like:
Dim x as integer = sqlQuery("Select count(*) FROM ...")
 Currently i have it all working by creating a table and making it invisible and just pulling data from the table but thats sloppy and pretty ineffecient if i databind a table for every single topic name.

Code To Check If DB Is Online

Apr 4, 2008

I want to check whether or not a DB is online when a report is run. If it is offline I would like to display a friendly message.

Currently my users get error messages when they run a report against a database that is offline. They get incomplete reports if they run a report while the database is being restored.

How can I detect the state of the database and display the appropriate friendly message? Is there a property to check or an event where I should write some code?

I look forward to your response.

How To Show Description In Report Instead Of Code (Desc For Code Is In Master Table)

Mar 28, 2007

Dear Friends,



I am having 2 Tables.

Table 1: AddressBook
Fields --> User Name, Address, CountryCode



Table 2: Country
Fields --> Country Code, Country Name


Step 1 : I have created a Cube with these two tables using SSAS.



Step 2 : I have created a report in SSRS showing Address list.

The Column in the report are User Name, Address, Country Name



But I have no idea, how to convert this Country Code to Country name.

I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]



Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.




Thanks in advance.

Query Help, What Columns For All Records Are Empty

Aug 30, 2004

I am wanting to make a query to find out if there are any columns in a table that are null for all records.

So far I am using a cursor that holds all the column names of that table and then a stored procedure that would use a loop to cycle through all the column names in a query to essentially count the number of nulls for each column and then an If statement to check to see if the #of nulls = to the number of records.

What isn't working is my query to count the number of nulls...Here is my query

select count(*)
from XYZ
where @cName is null

Ive tried declaring cName as a sysname, and varchar, neither work.

Also, I've tried using COL_NAME(OBJECT_ID('XYZ'), someColumnIndx)...I think this would be the better choice just because I wouldn't need to use a cursor, but both aren't working.
I am a bit new to MSSQL and don't know my way around the system tables. Is there a sys table that would give me this info so I wouldn't need to perform a query?

Any info would be great.

Empty Table Problem

May 16, 2007

I am creating three tables in a DataSet using three stored procedures and I need a way to know that either the tables have at least one row or preferably which if any has no rows.  How can I do that?
using three SP's, one for each table:SqlCommand cmd = new SqlCommand("CompanyCheck", con);SqlCommand cmd2 = new SqlCommand("ContractorVerify", con);SqlCommand cmd3 = new SqlCommand("StoreLocation", con);
  cmd.CommandType = CommandType.StoredProcedure;  cmd2.CommandType = CommandType.StoredProcedure;  cmd3.CommandType = CommandType.StoredProcedure;  cmd.Parameters.AddWithValue("@CompanyID", CompanyID);  cmd2.Parameters.AddWithValue("@CompanyID", CompanyID);  cmd3.Parameters.AddWithValue("@CompanyID", CompanyID);  SqlDataAdapter da = new SqlDataAdapter(); 
da.SelectCommand = cmd; DataSet ds = new DataSet();        try        {            da.Fill(ds, "CompanyInfo");            da.SelectCommand = cmd2;            da.Fill(ds, "ContractorInfo");            da.SelectCommand = cmd3;            da.Fill(ds, "StoreInfo");                   }        catch        { throw new ApplicationException("Data error"); }        finally        {            con.Close();        }

Table Empty Of Content

Sep 10, 2001

I have a particular production database that on a few recent occasions has suddenly had one of it's tables empty of content. Now there are no jobs or triggers in place neither is any stored procedures that could perform a delete or alter table operation in place. The permissions have been set not to allow this either. The datatype is text only. What is intriguing is the QA server has an exact mirror and this dosen't happen. Has anyone come across this sort of phenomenon?

Design Table Is Empty.

Mar 1, 2000

I can use the Design Table option in every database and any user table on my server except for two databases which were transfered from a SQL 6.0 server.

I can't even use Design Table to create a new table in these databases. I get the Design form up and it allows me to add columns, but when I try to save the changes I get the following error message:

ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'full'.

One thing I have noticed is under Users for the database, all my users come up as 'via group membership' for the Database Access column for the database I am having problems with. All other databases the users come up as 'Permit' for the Database Access column. I assume this has to do with security. But I have tried everything to change this. I can not get a user to come up as 'Permit' under these two converted databases.

Does anyone have any ideas?

Sysperfinfo Table Empty

Jul 15, 2004

I'm running SQL 2000 (SP3) on top of Windows NT 4.0 (SP6).

I have a couple of processes that look at the sysperfinfo table every day to collect some performance/metric type information. It works for all my other servers (mostly SQL 2K/Win2K) except for this one.

Why is the table on this one server empty?

I do have one other SQL 2K/Win NT server. The sysperfinfo table on that one is fine.

the only other clue/difference is that the server which has the empty table is a named instance install of SQL 2K.

Any hints?

Regards,

MDX Query To Display No Records For Empty Rows

Jan 9, 2007

Hi,

I am facing with the following problem.

I am using bar chart to display my report.

My MDX query is as follows:

SELECT
NON EMPTY { [Measures].[SUM_COUNT] } ON COLUMNS,
TopCount ( Filter ( {[DIM].[NAME].[NAME]}, [Measures].[SUM_COUNT] <> 0 ) , 10, [Measures].[SUM_COUNT] ) ON ROWS
FROM
[USAGE]

where <criteria>

I want to show the topmost 10 records. For some criteria I get the results in the chart.

But for some criteria or say for wrong criteria, there are no records. In such a case the X-axis contains all values for {[DIM].[NAME].[NAME] and value for the Y-axis is all 0. Its kind of blank report it will restrict to 10 records.

In such a scenario I want to show a message to the user saying "No records found", which I have set in the No Rows property of the chart.

If I remove the TopCount clause then I get the above message, which is obvious.

So how do I acheive the same message but at the same time limiting the records to 10?

How can I acheive this in my scenario? Can something be done at the query end?

any help is appreciated.

Thanks in advance!

Aggregate Task When Query Returns Empty.

Jan 13, 2008



To create a strike file for a text file output, I piped the output of a query throught a mulitcast. One output is the actual flat file, the other output is the strike file. The next task for the strike output is an aggregate count and sum functions. If the original query returns no records, the count shows zero, but the sum shows NULL. Further down the process I have to pad out the values with zero's, but that NULL is causing problems. How do I convert the Null to either an empty string, or a value of zero?
Thanks
