View 3 RepliesHow can I enter NULL manually in one of the rows in Sql Server database. Those rows does not contain any data.
View 3 RepliesI'm hoping that someone can help. This is my first time posting and fortunately I can normally find what I need but this time I am stumped.
I have a query that produces a date range. The problem is I want to insert or at lease display the dates between even if they don't show up in table. Here's the problem.
My intial query is
select date_of_call
from call_data
where date_of_call >= '2001-09-01' and date_of_call <= '2001-09-15'
order by date_of_call
Results:
2001-09-03 00:00:00.000
2001-09-07 00:00:00.000
2001-09-10 00:00:00.000
2001-09-13 00:00:00.000

2001-09-13 00:00:00.000
2001-09-14 00:00:00.000
When I do a group by and count it looks like this:
select date_of_call, count(date_of_call) as Count_Date_of_Call
from call_data
where date_of_call >= '2001-09-01' and date_of_call <= '2001-09-15'
group by date_of_call
order by date_of_call
Date_Of_Call, Count_Date_of_Call
2001-09-03 00:00:00.0001
2001-09-07 00:00:00.0001

2001-09-13 00:00:00.0005
2001-09-14 00:00:00.0001
If you notice out of 15 days it only shows 5 days. I am wondering how I can insert the days missing and insert either null or 0 values in the count column so it would look something like this:
Date_Of_Call, Count_Date_of_Call
2001-09-01 00:00:00.0000

Hi there,
I have a fairly generic question regarding database design.
I am working on my first database using SQL Express.
I am testing the database by inserting records into the pre defined tables.
Sometimes I forget to input text into a non null field. When
this happens it displays an error and then skips a few rows
which makes my row numbering messy. For example say I have
Row 1, Row 2 Row 3 all nicely formatted but on Row 4 I make a mistake
this row then disapears and their is gap between 3 and 5 where 4 was.
Although I am just testing, I was wondering what happens in a real
scenario if an inexperienced data input person makes a few mistakes it
makes the database numbering systems look bad. In this case
is it common to make most fields NULL to allow for admin errors??
Hi, how do i do a select statement with asp.net to return a record if a field is null. I have the following code:
SqlCommand cmd = new SqlCommand("SELECT * FROM Categories WHERE ParentId = @ParentId", cn);.Parameters.Add("@ParentId", SqlDbType.Int).Value = parentId != null ? (object) parentId : DBNull.Value;cn.Open();
The variable parentId is a nullable int. However when i pass in a null value it doesn't return anything even though there are records in the database that have a null value for the ParentId field.
Appreciate if someone could tell me what i am doing wrong. Thanks

when inserting or updating fields in sql server and the field is blank sql still adds several spaces into the field. Then if I try to check whether a field is empty or not for display I get incorrect results because fields that should be empty have 2 or 3 spaces in them instead and therefor aren't selected as being empty. Is there any way around this? to force the fields to be saved as blanks or null?

I thought this was working, but apparently it was not. I was wondering how I would create a SELECT Statement for values that are blank (Equal to ""). I really could have swore that this was working, but I guess it wasn't.
Here is my code:

try

string conString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Environment.CurrentDirectory + @"MyDB.accdb;Jet OLEDB:Database Password=MyPassword;";
// create an open the connection
OleDbConnection conn = new OleDbConnection(conString);
OleDbCommand command = new OleDbCommand();
command = conn.CreateCommand();
// create the DataSet
DataSet ds = new DataSet();
// run the query
command.CommandText = "SELECT ID AS [#], Company AS [Company], FName AS [First Name], LName AS [Last Name], Type AS [Type] FROM Table1 WHERE Tags = @P0;";
OleDbDataAdapter adapter = new OleDbDataAdapter();
adapter = new OleDbDataAdapter(command);
command.Parameters.Add("@P0", OleDbType.VarChar).Value = "";
adapter.Fill(ds);
// close the connection
conn.Close();
bindingSource1.DataSource = ds.Tables[0];
DataGridView.DataSource = bindingSource1;
// set the size of the dataGridView Columns
this.DataGridView.Columns[0].Visible = false;
this.DataGridView.Columns[1].Width = 234;
this.DataGridView.Columns[2].Width = 50;
this.DataGridView.Columns[3].Width = 50;
this.DataGridView.Columns[4].Width = 75;
//Sort on the Title Column
DataGridViewColumn sortColumn = DataGridView.Columns[1];
ListSortDirection direction;
direction = ListSortDirection.Ascending;
DataGridView.Sort(sortColumn, direction);
//Set the Selected Property of the First Row to False
DataGridView.Rows[0].Selected = false;
}
catch
{
}

I am trying to validate and import a Excel file into the database table using script component. The file contains some blank columns in the sheet.

I was thinking aMicrosoft Access database but its not ideal because not everyone herehas Access?Can you do it with Excel?

View 2 Replies View RelatedIf a database's collation is blank under enterprise manager and NULL with SELECT DATABASEPROPERTYEX('<Database_Name>', 'Collation') does this mean it has the same collation as the server?
The reason I ask is that I restored a database with a different collation to my server and so I expected the different collation name to show up.
Its showing as blank though...
I thought databases kept their original collation even if restored to another server.
(The database was restored as a new database).
I am passing few parameters to the sql function to do some calculations. If the input parameter is null or blank, then I want to set the input parameter to the value zero

I have created a report with a stored proc which takes a parameter whose default value is null. Now when I run my stored proc in Enterprise Manager without any params I get 4 rows otherwise with proper parameter I get 2 rows.
Now I set the params value to allow for Null and blank values. When I run the report if I provide parameter value it works fine but if i try to run it without any param it shows an empty report while the stored proc running without params shows 4 rows.
I have earlier sucessfully created reports where stored procs had 4 params out of which 3 where defaulted to null. And so I set the allow nulls, Allow Blanks values to be true for those params in Rep services. So when I selected value for 1st param and ran the report I got the desired report. But this time I have only one param which can be null. But its not working.
Thanks in advance.

I have built a SSIS package that bascially updates two columns in table A...the update statement reads;
update Table A
set Colum 1 = ?,('?' is a variable)
Column 2 = ?
In my SSIS package, I would like to be notified/capture, if one or both variables are null....How do I do that ?..error log ?
The package runs fine both ways (if variables are null or not)

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 attempting to update a sql db using the update and parameter code in VB.net 2003 through MSDE for a web application. It updates changed data OK, but if the textbox value is deleted, the code does not update the sql db. I am new to this, and I'm sure it is something simple. Here is some sample code.
SqlConnection1.Open()
strSQLu = "UPDATE table1 " _
& "SET Field1Tag = @Field1Tag, Field2Tag = @Field2Tag " _
& "WHERE (Field1Tag = @Field1Tag) "
cmdCategoriesUpdate.CommandText = strSQLu
With cmdCategoriesUpdate
.Parameters("@Field1Tag").Value = txtFld1.Text
.Parameters("@Field2Tag").Value = txtFld2.Text
End With
cmdCategoriesUpdate.ExecuteNonQuery()
SqlConnection1.Close()
Hi,
In SSIS flat file import using fastload, I'm trying to import data into SQL 2005 previously created tables.
The table may contain column that are NULLable BUT there is NO DEFAULT for them.
If the incoming data from flat files contains nothing either between the delimeters, how can I have a NULL value inserted in the column instead of blank/empty string?
I didn't find an easy flag unless I'm doing something wrong. I know of at least two ways to do it the hard way:
1- set the DEFAULT(NULL) for EVERY column that needs this behaviour
2-set up some Derived Column option in the package to return NULL if the value is missing.
Both of the above are time consuming since I'm dealing with many tables. Is there a quick option to default the value to NULL WHEN there is NO data ELSE insert the data itself? So the same behavior that I have right now except that I want NULL in place of empty string/blank in the varchar(x) columns.
Thanks

I need to convert a a string column to integer. Before converting, I need to check if it has blank values then convert it to NULL. Someone told me that its easier to convert it to NULL before converting to integer.

Hi,
I have a query like this one
SELECT expense_id, CAST(expense_id AS char(10)) + ' - ' + CAST(trip_km AS char(5))+ ' - ' + CAST(expense_amount AS char(5)) + ' - ' + charge_centre AS ExpenseDesc
If charge center is null, I need to ignore this field. How can I achieve this? The reason is that if any of the field is null, it will return ExpenseDesc as null.

Here is the problem that I am struggling with. The structure is:
States: StateID, StateName
Counties: CountyID, CountyName
Cities: CityID, CityName
Zips: Zip, StateID, CountyID, CityID
Regions: RegionID, RegionName
Region_Data: RegionID, StateID, CountyID, CityID
The thing about the region is that it can be defined by states only, in which case CountyID and CityId are NULL, can be defined by Counties too, in which case only CityID is NULL or it can be defined up to City level, in which case all 3 are set to something. Example, Northeast would be all cities from northeast, but Pocono would be just some counties in PA, and so on...
The issue is now selecting all cities that belong into a region... Normally I would join the Zips table with the Region_Data table and retrieve all CityIDs... The issue is that, as I said, the CountyID and CityID might be null for some records, so I am not sure how to retrieve them?
I came up with one idea in which I create 3 temporary tables and I select in them all the records that have 1) only state, 2) only state and county, 3) all 3, then I join each and I union the results...
But I am wondering if there is a way to do the select in one shot?
Any idea? I appreciate your help,
Thank you,

Requirements:
1) Cannot have results in which both m.homephone & d.homephone are both null, or both m.workphone & d.workphone are both null in the result set
2) We also do not want to see any combos where one homephone is null and the other has only the char 0....same for workphone...no null & 0 combinations.
e.g.
m.homephone d.homephone
null 0
0 null
The phone fields are varchar
I know this is hidiously wrong but is my first sloppy attempt at best:
select m.number, m.homephone as master_homephone, d.homephone as debtor_homephone, m.workphone as master_workphone, d.workphone as debtor_workphone
FROM master m
INNER JOIN debtors d ON d.Number = m.number
where (d.homephone <> m.homephone OR d.workphone <> m.workphone)
AND (d.homephone IS NOT NULL AND m.homephone IS NOT NULL)
AND (d.workphone IS NOT NULL AND m.workphone IS NOT NULL)
AND NOT ((d.homephone IS NULL AND m.homephone = '0') OR (d.homephone = '0' AND m.homephone IS NULL))
AND NOT ((d.workphone IS NULL AND m.workphone = '0') OR (d.workphone = '0' AND m.workphone IS NULL))
