Hi,
When I try to insert a new record into a table that has a datetime field that allows nulls, a default 01/01/1900 date is inserted instead of null. I recreated the table and set the datatype to smalldatetime and I still get the error. What have I missed?
I'm importing data form an Excel file to a Sql Server Database. Some of the data imported represents time as a double type so i convert the times into DateTime to be inserted into the database. The time values that aren't available in the Excel file are 0.. so what i want to do is insert null into the database for all the values that are 0 in the excel file... How do i do that based on this code i have so far:protected void ButtonImport_Click(object sender, EventArgs e){PanelUpload.Visible = false;PanelView.Visible = false;PanelImport.Visible = true;LabelImport.Text = "";OleDbCommand objCommand = new OleDbCommand();objCommand = ExcelConnection(); OleDbDataReader reader;reader = objCommand.ExecuteReader(); while (reader.Read()){DateTime? in_1 = null;DateTime? out_1 = null;DateTime? in_2 = null;DateTime? out_2 = null; int emp_id = Convert.ToInt32(reader["emp_id"]);DateTime date_entry = Convert.ToDateTime(reader["date_entry"]);if (Convert.ToDouble(reader["in_1"]) != 0)in_1 = ConvertDoubleToDateTime((double)reader["in_1"]);if (Convert.ToDouble(reader["out_1"]) != 0)out_1 = ConvertDoubleToDateTime((double)reader["out_1"]);if (Convert.ToDouble(reader["in_2"]) != 0)in_2 = ConvertDoubleToDateTime((double)reader["in_2"]);if (Convert.ToDouble(reader["out_2"]) != 0)out_2 = ConvertDoubleToDateTime((double)reader["out_2"]); ImportIntoAttendance(emp_id, date_entry, in_1, out_1, in_2, out_2);} reader.Close();}protected void ImportIntoAttendance(int emp_id, DateTime date_entry, DateTime? in_1, DateTime? out_1, DateTime? in_2, DateTime? out_2){ SqlDataSource AttendanceDataSource = new SqlDataSource();AttendanceDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["SalariesConnectionString1"].ToString();AttendanceDataSource.InsertCommandType = SqlDataSourceCommandType.Text;AttendanceDataSource.InsertCommand = "INSERT INTO Attendance (emp_id, date_entry, in_1, out_1, in_2, out_2) " +"VALUES ('" + emp_id + "', '" + date_entry + "', '" + in_1 + "', '" + out_1 + "', " +"'" + in_2 + "', '" + out_2 + "')"; int rowsAffected = 0;try{rowsAffected = AttendanceDataSource.Insert();}catch(Exception ex){LabelImport.Text += "<font color=red>" + ex + "</font><br />";} }private DateTime ConvertDoubleToDateTime(double dbTime){string[] SplitTime = dbTime.ToString().Split('.');string hours = SplitTime[0];string minutes = String.Empty;string time = String.Empty; if (dbTime.ToString().IndexOf('.') != -1){if (SplitTime[1].Length >= 1){if (SplitTime[1].Length == 1)minutes = Convert.ToString(Convert.ToDouble(SplitTime[1]) * 10);else if (SplitTime[1].Length > 1)minutes = SplitTime[1];}}elseminutes = "00";time = hours + ":" + minutes;return Convert.ToDateTime(time);}

can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task.
In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful.
Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
If Not Row.Datum1_IsNull Then
Row.OutputDatum1 = Row.Datum1
Else
Row.OutputDatum1 = CDate(System.Convert.DBNull)
End If
Any help welcome.
Hi all
I have a calculated fields in report designer such as a + b + c + d. In sql server if I run this query
select a + b + c + d from table1
and any of a,b,c or d is null, the result is null.
whereas in calculated fields, it does not return null but infact ignores the null value and treats it as zero.
I want my calculated field to be null if any of the values are null.
Is it possible? I cannot use the isNothing function because I have too many fields and it will be quite cumbersome.
Thanks
Hey everyone,
This is probably a very simple question, but I am just stumped. I am storing different name parts in different fields, but I need to create a view that will pull all of those fields together for reports, dropdowns, etc.
Here is my current SELECT statement:
SELECT m.FName + SPACE(1) + m.MName + SPACE(1) + m.LName + ', ' + m.Credentials AS Name,
m.JobTitle,
m.Company,
m.Department,
m.Address,
m.City + ', ' + m.State + ' ' + m.Zipcode AS CSZ,
m.WorkPhone,
m.FAX,
m.Email,
c.Chapter,
m.Active,
s.Sector,
i.Industry
FROM tblMembers m
LEFT OUTER JOIN tblChapters c
ON m.ChapterID = c.ChapterID
LEFT OUTER JOIN tblSectors s
ON m.SectorID = s.SectorID
LEFT OUTER JOIN tblIndustries i
ON m.IndustryID = i.IndustryID
WHERE m.DRGInclude = 1
My problem is that I don't know how to test for NULL values in a field. When you concatenate fields that contain NULL values, the entire contactenated field returns NULL. I am not aware of an IF statement that is available within the SELECT statement.
The first thing I would like to accomplish is to test to see if MName contains NULL. If it does I do not want to include + SPACE(1) + m.MName in the clause. Then, if Credentials contains NULL I do not want to include + ', ' + m.Credentials in the clause.
Can someone tell me what I am missing? Is there a function that I can use for this?
Thanks,
Hi all,
I have a projects table with 2 foreign key fields that both link to the same employees table because a project has a Package Engineer (PkgEngineerID) and a Contract Administrator (PkgContrAdmin). When I try to insert a record with null values for either or both of these foreign keys I get an error:
The data in row xxx was not commited. The record can't be added or changed. Referential integrity rules require a related record in table 'tblEmployees'. The transaction ended in the trigger. The batch has been aborted.
An insert statement for the above would look something like the following:
INSERT INTO tblPackages (PkgNo, PkgName, PkgEngineerID, PkgContrAdmin, PkgRemark)VALUES (1234, 'My Package', NULL, NULL, 'My Package remark')
And the create table statements are:
USE [PASSQL]GO/****** Object: Table [dbo].[tblPackages] Script Date: 01/15/2008 23:25:26 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE TABLE [dbo].[tblPackages]( [ID] [int] IDENTITY(1,1) NOT NULL, [PkgNo] [nvarchar](20) NULL, [PkgName] [nvarchar](255) NULL, [PkgEngineerID] [int] NULL, [PkgContrAdmin] [int] NULL, [PkgRemark] [nvarchar](255) NULL, [upsize_ts] [timestamp] NULL, CONSTRAINT [aaaaatblPackages_PK] PRIMARY KEY NONCLUSTERED ( [ID] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOALTER TABLE [dbo].[tblPackages] WITH NOCHECK ADD CONSTRAINT [FK_tblPackages_tblEmployees] FOREIGN KEY([PkgEngineerID])REFERENCES [dbo].[tblEmployees] ([ID])GOALTER TABLE [dbo].[tblPackages] CHECK CONSTRAINT [FK_tblPackages_tblEmployees]GOALTER TABLE [dbo].[tblPackages] WITH NOCHECK ADD CONSTRAINT [FK_tblPackages_tblEmployees1] FOREIGN KEY([PkgContrAdmin])REFERENCES [dbo].[tblEmployees] ([ID])GOALTER TABLE [dbo].[tblPackages] CHECK CONSTRAINT [FK_tblPackages_tblEmployees1]
And:
USE [PASSQL]GO/****** Object: Table [dbo].[tblEmployees] Script Date: 01/15/2008 23:28:01 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE TABLE [dbo].[tblEmployees]( [ID] [int] IDENTITY(1,1) NOT NULL, [EmpName] [nvarchar](255) NULL, [EmpShort] [nvarchar](255) NULL, [upsize_ts] [timestamp] NULL, CONSTRAINT [aaaaatblEmployees_PK] PRIMARY KEY NONCLUSTERED ( [ID] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]
Any ideas on how to accomplish this would be great!
Thanks in advance!
I am using a DAL and i want to insert a new row where one of the columns is DATE and it can be 'NULL'.
I am assigning SqlTypes.SqlDateTime.Null.
But when the date is saved in the database, i get the minvalue (1/01/1900) . Is there a way to put the NULL value in the database using DAL????how can i put an empty date in the database?

Hi,
I have fields in my table which allow nulls. Is it efficient to not insert anything (the field automatically shows up as null in this case) and leave or store some value into it. The field is a smallint field?

If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types.
I am curious as to what others are doing to handle this?
Hi, i'm new to SSIS and trying to import some csv files (comma delimited) into SQL Server. A NULL value for a CHAR column is correctly regonized as NULl in SQL Server, but a NULL value for of a mapping to a VARCHAR column in SQL Server is not recognized correctly and i get the value "'NULL'" in SQL Server (including the single comma.
Sample:
CSV file contains columns A and B. A and B contains the Text NULL.
Column A is mapped to a CHAR field, and column B is mapped to a VARCHAR field in SQL Server.
After the import, SQL has the following value: A = NULL as NULL, B 'NULL' as text.
did anyone else had this problem?
thanks so much for any help.
Hi
I have a really simple query which i can't figure out why its not working. I have a table called 'ADMIN' which has a datetime field called 'date_edited'. Because the majority of records have never been edited, i have allowed null values and they are filled with 'NULL' in each record. How ever, when i try:
SELECT * FROM ADMIN WHERE date_edited = NULL
I get no records, but i can see and know i have hundreds! I know i'm doing somthing really stupid, but for life of me can't figure it out! :eek:
thanks
Hello all,
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
"SELECT DISTINCT fire_id, police_ID, fire_opt_in_out, police_opt_in_out FROM ipt_tbl " & _
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
Any suggestions?
thanks for your time...
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

Hi,
I'm inserting a datetime values into sql server 2000 from c#
SQL server table details
Table nameate_test
columnname datatype
No int
date_t DateTime
C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");
connectionToDatabase.Open();
DataTable dt1 = new DataTable();
dt1.Columns.Add("no",typeof(System.Int16));
dt1.Columns.Add("date_t", typeof(System.DateTime));
DataRow dr = dt1.NewRow();
dr["no"] = 1;
dr["date_t"] = DateTime.Now;
dt1.Rows.Add(dr);
for(int i=0;i<dt1.Rows.Count;i++)
{
string str=dt1.Rows["no"].ToString();
DateTime dt=(DateTime)dt1.Rows["date_t"];
string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')";
SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase);
cmd.ExecuteNonQuery();
MessageBox.Show("saved");
}
When I run the above code, data is inserted into the table
The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?
thanks,

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

Hi,
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
e.g.
Rank Blah Blah
1 - -
2 - -
3 - -
NULL - -
NULL - -
At present the NULLs are at the top of the list, but I do not want my ranking in descending order. Any suggestions?
Thanks

I would like to compare 2 fields.. One of which is generated by the application upon insert. The other which is today's date.
In other words I want all records with today's date.
Problem is I get no results because I'm also apparently comparing the time.
Do I use a CONVERT function on my select & GETDATE outputs?
Thanks,

I have a table with a DateTime field that has Dates in the format of mm/dd/yyyy I want to do a simple count on the table for the previous day but keep getting 0 for the results. Here is the script I've been trying.
SELECT COUNT(*)
FROM mytbl
WHERE Collected_Date = DateAdd (dd, -1, GetDate())
It appears to me that the time portion of the DateAdd function keeps the matches that I am looking for from happening. What am I missing or am I going about this all wrong?
Thanks for any help
I am trying to join two tables and the datetime fields need to be part of the join. They contain times in the fields too. I just need them to join on the date part though. Is there maybe a way to just return the mm/dd/yyyy format and join on that? Any and all help is appreciated.
Thanks,

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.
Thanks
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))

View 5 Replies View RelatedHi 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??
I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.
I want to do something like this- make the fields in red NULL while leaving out the ones in green.
{ Col.Group I } { Col. Group II }
Col1 Col2 Col3 Col4 Col5
------- ------- ------- ------- -------
ValA ValA2 ValA3 ValA40 ValA50 {
ValA ValA2 ValA3 ValA40 ValA50 Row. Group A
ValA ValA2 ValA3 ValA41 ValA51 }
ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B
ValB ValB2 ValB3 ValB41 ValA51 }
I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.
Any idea how I might be able to do this in my stored proc. efficiently?
Thanks,

I'm using SQL Server Express and am trying to import a CVS file. The CVS file contains a string field (named DAS) that represents a Date. This field can be null.
I've tried using the DTS Wizard to import this CVS file and convert the DAS field to a Date, which works great until it hits a record with a NULL DAS field. It then throws a convertion error.
Still using the DTS Wizard, I've changed the DataType of the DAS field in the Source file to [DT_DATE], it works fine but all the null dates are converted to 12/30/1899.
Is there a way (DTS Wizard or something else) that will allow me to import these CVS files with null Date fields and keep them as null in SQL Server table.
Thanks for any help,
Jon
