How To Check If A Table Is &<empty&> Ie Doesnt Contain Any Rows
Aug 18, 2007
Hi, is there a way I can check if a table is empty and contains no
rows?
I have a Table1 which being dynamic can sometimes end up with now
columns what so ever. I'm using Table1 in one of my views along with 2
other tables and I would like put a condition at the...something like
AND Table1 IS NOTEMPTY
When 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.
How do I go about iterating through every table in my database and empty each table so they contain no data? I don't want to drop the tables and re-create them either.
I also have a RESOURCES table of phrases (for translation purposes) similar to this:
res_id res_lang res_phrase AccessDenied en Access Denied
For some rows in the resources table I do not have all language codes present so am missing some translations for a given res_id.My question is what query can I use to determine the RESOURCE.RES_IDs for which I do not have a translation for.
For example I might have a de, en, cz translation for a phrase but not a pl phrase and I need to identofy those rows in order that I can obtain translations for the missing RESOURCE rows.
How can we monitor the all tables in all databases and send notifications to the team.Is there a way to check to find the no of rows and size of a table last month and find out growth % now
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
declare @user varchar(30) = '' if(@user is not null or @user <> '') BEGIN print 'I am not empty' END ELSE BEGIN print 'I am empty' ENd
The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.
What is the T-SQL command to check for NULL or '' in a field in one statement? I would like to change the following code to be more readable (without the OR).
On my office PC I have a strange problem with Data Flow Tasks. When I check-in a package into Source Control (Team Foundation) I usually have some empty Data Flow Tasks in the packages...even if I haven't changed that Flow Task.
This is really frustrating cause when running the package all goes well, but after a whil you notice that some tables are empty.
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"

I am using SSDT to deploy my database project. This project has a post deployment script and i am creating a new user in this post deployment script. I have used sqlcmd variable to capture the username. I am doing a null/empty check for this variable and my code looks like below.
IF (([$(UserName)] IS NOT NULL) OR ([$(UserName)] <> '')) BEGIN CREATE USER [$(UserName)] WITHOUT LOGIN WITH DEFAULT_SCHEMA = dbo; GRANT CONNECT TO [$(UserName)]; END
When i execute this, I am getting below error.
Could not deploy package.
Error SQL72014: .Net SqlClient Data Provider: Msg 207, Level 16, State 1,Line 15 Invalid column name 'User Name'.
Error SQL72045: Script execution error. The executed script:
I want to make a query, stored procedure, or whatever which will only display the primary key where there does no exist a foreign key in linked table.For example. If I had two tables with a one to many relationship.A [Computer] has one or more [Hard Drives]. I want to select only those computers which do not have a Hard Drive(s) associated with them. That is, show all computers where the Computer_ID field in the [Hard Drives] table does not exist. This seems simple but I'm drawing a blank here.
Good day, I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows. I thought the connection is not the problem since I got my columns right. Below is my code snippet. Thanks! const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) " + "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1"; SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection); DataTable dt = new DataTable(sometablename); adapter.Fill(dt);
I did some tsql a year or so ago, it wasnt much but it allows me to do most things i need to do in my job.
I have created a new database for bookings, each booking has all the relevant details and also the date that it will occur. im trying to create a script that will look for the 10 soonest dates that there is no booking for. at first i thought it would be easy, but now once i have got round to creating it i cant seem to think of a way to make it work!
I am using a DTS package where one of the inputs is an Excel Sheet. Actually this sheet is updated manually whenever required i.e once a week or sometimes once a month, but the DTS package runs everyday.
Whenever new rows are added or deleted manually in the excel sheet, empty rows are showed in the sheet after the last row of data. This hinders the DTS package, because the destination table to which the data in the Excel sheet is sent has Primary keys in it.
Can anyone suggest me how to avoid getting the empty spaces in the excel sheet.
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?
I have had at least 2 occurences of a DFT OLEDB source returning the correct number of rows but all rows are empty (they contain zeros or ''). This has happened in two different places in different SSIS packages within an ETL task. In one case the source was on a different server running SQLServer and in the other it was a different database on the same server as the SSIS package. This occured running on different servers, one with SQL 2005 SP2 and the other without. Both are 64 bit AMD systems running 64 bit SQL 2005. As there is a derived column transformation that has performed the derivation on the blank columns I assume the problem is with the OLEDB source but it could be with the data stream from the OLEDB source to to whatever follows. Has anyone else had this problem and does anyone know of a fix?
I have been looking for a solution for this for some time and have came up empty handed.
I have 2 servers development box and a live box. Time has passed and my live box has a lot of new data in the database and now I need to update the dev box so I can properly test with real data. Problem here is I want to keep the records that are in the dev box, update them if they exsist on the live box, because live server may or may not contain that record and isert all records that are not on the dev box database.
I hope I am making some sense here, I think I am just making it more difficult then it has to be.
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."
I know this error normally comes if there are dups in a field that doesnt allow.
I have huge export files in a DB and i need to check if there are any datasets that have the same value in the first column, but a different in another one, via a query of course.
Like this:
ID IS NULL 1 1 2 1 3 0 1 0
The expected ID i get as a result of my query should be 1 in this case.
Hi. As the title, I am try to figure out how to write script to prevent duplicated rows before loading data from couple csv files to the OLE database table. Another quick question, when I use Data Conversion to convert data from string to datetime or decimal type, it always return error like potential data loss.
We run the SSIS through tidal scheduling agent using the dtexec utility. We want to see the number of rows transfered while running or after it has run our package. We require answers for the following:
1) How to see the number of rows transfered while running the package using dtexec utility
2) what parameter should be used in dtexec command line to get the number of rows transfered in the Log file after execution.
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(); } Thank you
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?
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.
