Check If SqlDataSource Is Empty In CodeBehind
Feb 10, 2006This 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, 2004i 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

Append Query To Insert 80000 From One Table To Empty Table
Jul 22, 2012All, 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."

Empty Table Problem
May 16, 2007I 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(); }
Thank you
Table Empty Of Content
Sep 10, 2001I 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?
View 2 Replies View RelatedDesign Table Is Empty.
Mar 1, 2000I 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, 2004I'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?

Empty A Table Before Using DTS To Append Records?
Jul 20, 2005In Access I have a macro that, each night, takes a table with aprimary key defined in it, and deletes all the rows. Then itimports/appends records from a fixed width text file. In this way,since the table is not deleted and recreated, the primary key is keptintact.What would be the equivalent SQL method for doing this in an automatedway? I've tried letting DTS import the table from Access, but theprimary key is lost. Is there some way to "empty" a table instead ofdropping it, and then append new records so that the table will end uphaving the primary key I want it to have?Thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake.

View 4 Replies View RelatedCannot Insert Rows Into Empty Table
Mar 3, 2008When i try to insert new rows using SSIS into an emty table in my database, SSIS freezes. The same happens when i use a lookup on an empty table.
The only solution i have found is to manualy insert a row and remove it afterwards. When i have done this SSIS works without a glitch.
I start off by taking a script of a existing database and applying this script on a new database. So that i create an empty duplicate of my current database.
Any ideas why SSIS freezes? Do i have to initialize something first in my database? It is really annoying that i have to insert a row and delete a row into every table i want to use.
RsInternalError While Rendering An Empty Table
Jan 28, 2008Hi,
I'm using the Business Intelligence Studio for designing reports in VS2005 with SQL-Server 2005 Standard used on a TFS server.
On my report I have several tables each related to a previously defined dataset. Now, if a dataset returns no data, I would expect, that the table shows the header but no rows. This is true, if the table is located on the first page of the report and used directly in the preview tab of a report project. If such a table is located on following pages, I get an rsInternalError when switching to the second page. Trying to export the report, e.g. pdf, directly results in this error. When trying to view the report on the report server, the error appears also at once.
If, in Visual Studio, clicking on the button "page layout" everything is fine: empty tables are shown correctly.
How can I avoid this error in my reports? I would like to publish my report (no fancy stuff, just simple text data), possibly containing empty tables, on the server that all team members can view it - without the error...
Thanks in advance,
Erik Steiner
Transact SQL :: Monitor When A Table Becomes Empty
May 12, 2015I am trying to work with a developer test a code change in their application. The db basically has a workload table and as it finishes processing each row in the table, it gets deleted from the table. I want to monitor when the db becomes empty/no rows in it to test how much the code changes have worked, how long does it take to process all rows in the table. Any quick way to do it at the db level instead of having to put something in the code just for this testing.
View 4 Replies View RelatedBroken Subscriptions Due To Empty Table
Jul 31, 2007Hi,
I was wondering what the best way was to deal with subscriptions breaking due to an empty table. I have subscriptions that people have scheduled to go out daily, but on certain days the table may be empty, in this case the subscription doesn't read the parameters for the report and then the subscription breaks.
My original solution involved creating a #temp table with the same columns as the original table and inserting one row into it which I'd union with the original table, this row in the temp table had all its values set to 0. The solution worked when I ran it in SQL Server Management Studio but it seems SRS doesn't like the INSERT INTO statement, which is the error I get, but I've read on these forums that it doesn't like #temp tables either. I proceeded to use a stored procedure with all the code in it, but I might have trouble filtering on multi value parameters, because at times these parameter lists get real big, plus I have to do this for multiple reports and don't want to get into creating stored procedures for each report.
Following is what the code I used look something like that executes and does the job in Management Studio but not SRS. I'm mainly just looking for the easiest and cleanest way to do this, since it'll have to be done across multiple reports, so disregard the code if there's an easier way to do it. Thanks in advance.

View 8 Replies View RelatedPopulating Empty Table With Sequential Numbers?
Jan 15, 2015I have a column within a table which is already truncated/deleted all records within (Microsoft SQL 2008). I have to now populate the column with sequential numbers up to 50,000 records arbitrary numbers (doesn't mater) up to 7 characters.
what SQL statement I need to write that will automatically polulate the newly empty table with A000001,A0000002,A0000003, or any form for that matter etc so that I can sort number the records within the table.

Stored Procedure Returning An Empty Data Table
Nov 20, 2007I've built a simple VS2005 ASP.Net web app that uses Crystal Reports for generating assorted reports. More specifically, when a report is called it executes the correct SQL Server Stored Procedure and returns a Data Table populated with with appropriate data. In my testing, everything seemed to be working fine.But I just did a test where I pressed the "Submit" button on two different client browsers at almost the same time. Without fail, one browser returns the report as it should but the other one returns an empty report; all of the Crystal Reports template info is there but the report is just empty of data. Considering that each browser is running in its own session, I'm confused about why this is happening.One thing: I did login as the same user in both cases. Might this be causing the problem?Robert W.Vancouver, BC

Lookup Finds Match On Empty Reference Table
Jul 6, 2006Hi all,
In BOL it says: "The Lookup transformation performs an equi-join between values in the transformation input and values in the reference dataset. Using an equi-join means that each row in the transformation input must match at least one row from the reference dataset. If there is no matching entry in the reference dataset, no join occurs and no values are returned from the reference dataset. This is an error, and the transformation fails, unless it is configured to ignore errors or redirect error rows to the error output. "
I have a lookup transformation which is supposed to find a match on two fields in the reference dataset (a table in my case) but strangely, when I execute my package and the reference table is empty the lookup still finds match for each row of my input dataset.
Does anyone have an idea why? I could'nt find anything about that in BOL.
Sébastien.
