Visual Basic 2005 Professional Edition:
I have an SQL database table that includes a BirthDate field. I would like to have this field as optional when adding a record, but, SQL insists on throwing an exception if the field is null.
I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("@option", adInteger, adParamInput, 4, update_option)
.Parameters.Append .CreateParameter("@mfg_ord_num", adChar, adParamInput, mfg_ord_num_length, "")
.Parameters.Append .CreateParameter("@mfg_start_date", adChar, adParamInput, 10, "")
Set rs_refresh_shipping_sched = .Execute
End
Please help
My tests have shown that if you use BCP to import records with a
date field as " ", it won't work.
Is there a way to get BCP to accept empty date fields?
Hi everyone,
I have two tables - caseinfo and steps.
Caseinfo shows when a particular case entered and exited a particular project. If the project hasn't ended yet, then the end date is NULL.
Steps shows the steps the case has gone through and the dates of those particular steps.
I need to join the tables to show the steps the case went through during a particular project, but I'm having trouble with the NULL values in the end dates.
If I join the tables so that the step date is between the start and end dates of the project, then I get no step information for the cases where the end date is NULL (that is, where the project hasn't ended yet).
Does anybody have any ideas?
Here are my tables, the query that shows the main idea (with the wrong result), and my expected results.
Thank you for reading.

I am using a Ms-Access DS which is accessed by a website's server-side scripts.
What I would like to do is set an existing record's date/time field to null. I have tried to simply alter its value by not including any data within the sharps (##), however that did not work.
How can I accomplish this?

I have a column say 'ActivationDate' which is a (database timestamp [DT_DBTIMESTAMP]) which I want to replace with an expression in derived columns
The condition is if 'ActivationDate' field is null or '' then 'Null' else 'ActivationDate'
I am struggling to write this condition. Without condition i.e. at present it saves the value in this database '1753-01-01 00:00:00.000'.
In the preview the 'ActivationDate'field does not show any thing so I recon it is either null or ''

A newbie
I embedded a SQL query in excel that gets some datetime fields like "TASK_FINISH_DATE"Â .
How can I convert a datetime field to a date field in SQL in a way that excel will recognize it as a date type and not a text type?
I tried:
CONVERT(varchar(8),TASK_FINISH_DATE ,3)
CONVERT(Date,TASK_FINISH_DATE ,3)
CAST(TASK_FINISH_DATE as date)
**all of the above returned text objectes in excel and not date objects.
I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.
What options do I have that will work?
I am trying to populate a field in a SQL table based on the valuesreturned from using substring on a text field.Example:Field Name = RecNumField Value = 024071023The 7th and 8th character of this number is the year. I am able toget those digits by saying substring(recnum,7,2) and I get '02'. Nowwhat I need to do is determine if this is >= 50 then concatenate a'19' to the front of it or if it is less that '50' concatenate a '20'.This particular example should return '2002'. Then I want to take theresult of this and populate a field called TaxYear.Any help would be greatly apprecaietd.Mark

I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE')
Can anyone out there help?
Please advise. Thanks.
Best.

A date field in a report returns the date value as:
2015-07-01 13:30:27.000
Is there any way I can script this to appear as:
01 July 2015 (or 01-07-2015 or 01/07/2015)Â - basically to cut out the hours, minutes and seconds?
The best I have managed is: CONVERT (varchar(17),DATE,113) AS Date1 but this still leaves me with:
01 July 2015 13:30
Brand new to this, so please bear with me.I'm using the following code fragment to update a datetime field on a SQL Server 2005 database table:cmd.CommandText = "Update Projects Set EntryDate = " & Convert.ToDateTime(txtEntryDate.Text)cmd.ExecuteNonQuery()The result of the update operation is the the database field contains the value "1900-01-01 00:00:00:000". This probably means that I passed nulls to SQL; however, I see a valid date in the txtEntryDate field on my web form (i.e., "06/18/2007"). I also did a "Response.write" to display the txtEntryDate and it looks Okay.Can someone tell me what I'm doing wrong?Thanks!Using Visual Web Developer 2005 Express.
View 1 Replies View RelatedI'm writing a view to check record counts in a table that has numerous datasets and therefore various "Activity Dates". Is it possible as part of the SQL statement to have a CASE statement for example so that it can identify the field to use as the activity date?
The field to use is being identified using a seperate table so at the moment I have CASE WHEN FieldToUse = '2' THEN MapCol ELSE '[Activity_Date]' END, where FieldToUse = '2' identifies the date field to use and the MapCol data is the field name to be used as the activity date.
Is this even possible?

Hi,
I am very new to using SQL. Our department usually uses Brio to query the various databases under our control. However, I have recently come against a problem that prompted me to create a custom SQL query which works well as far as it goes. My problem is looking for specific conditions in billing information I receive monthly. I would like to compare on of the date fields contained in the database with a field in the form of YYYYMM (200710, for October 2007) I have created a custom column generator that forms a date from the YYYYMM. I would like, however, do the translation on the fly and make the comparison during the query. The problem is that query without the date check returns a mass of data, only about 1 percent of which is what I want.
The beginning of the SQL query looks like this:
FROM From.T_Crs_Tran_Dtl WHERE T_Crs_Tran_Dtl.Crs_Bill_Yr_Mo IN ('200710', '200711', '200712') AND ((T_Crs_Tran_Dtl.Crs_Cde IN ('1G', '1V') AND (T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND (T_Crs_Tran_Dtl.Prev_Stats_Cde IN (' ', 'TK', 'TL') AND T_Crs_Tran_Dtl.Cur_Stats_Cde IN ('TK', 'TL') AND T_Crs_Tran_Dtl.Std_Tran_Typ_Cde='B') OR (T_Crs_Tran_Dtl.Prev_Stats_Cde='UN' AND T_Crs_Tran_Dtl.Cur_Stats_Cde='XX' AND€¦
It is the €œ(T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND€? part of the query that is just plain wrong. The business part of this statement takes the YYYYMM field and turns it into a date which is the last day of YYYYMM.
I hope someone out there can help me with making this comparison.
I appreciate your help.

I want to display only the date part of a date field which contains both date & time information.
For example I have the value '2013-11-14 00:00:00.000' in my result set, and ideally I would like to show only '2013-11-14'.
I have looked up the datepart() command, however I can't work out how to return all parts of the date, rather than just the year, month, or day.
I have a date held in a varchar field in a temporary sql table and I want to convert it into a sql date and it doesn't work. I can replicate this as below -
So I run
select
cast ('14/02/2014' as date)
and I get a conversion failed error.
I have passed createdDate from UI to Stored procedure.createdDate field declared with DateTime.it is having value 2014-07-01.I need to fetch records from the database based upon the created field.but Create_TM in database having value Date with timestamp.so how would i change the createdfield in stored procedure.

I have a table named "shift" and I need to setup my query to return only data where the field "startime" = today. The problem I am running into is the starttime field it laid out like "2005-12-29 14:00:00" with different time values. I need to ruturn everything that has todays date regardless of the time value. I tried using GetDate() but that is returning data for other days as well or just data before or after the current time. Does anyone have any suggestions? This is driving me crazy! Thanks, Garrett

Hi all,
I have a table, named systems, with fields as follows.
field datatype
___________________
system varchar(50)
modelID int
.... ....
... .... etc...
The modelID field is related to the Models table. Therefore, the value it expects is a number that already exists in a Models.modelID field.
In the systems table, I allow nulls for the model ID field. If I edit the table directly through SQL front end it allows me to enter a system name for example and leave modelID value as NULL.
My problem occurs when I try inserting into the table from ASP. Whether I leave the value I'm passing to the stored procedure for insert blank or NULL it gives me problems.
Is this a typical issue that can be resolved with a simple property change?
Please help me resolve this, I need to have the ability to leave certain fields empty even though they are related to other tables. Is that possible?
Thank you for any help in advance.

I am trying to convert a decimal date value to a date value that I can use in formulas but am having a lot of trouble.My date value currently shows in decimal format YYYYMMDD. I want to convert this to a date so I can then find the number of days between two dates.I have tried convert (datetime, convert(varchar(8),left(qhstdt,8))) with qhstdt as my decimal date field but I receive the error message below:
Error: SQL0204 - CONVERT in *LIBL type *N not found.
I have also tried converting it using (year(QHSTDT)*10000+100*month(QHSTDT)+ day(QHSTDT))) but when I convert the dates using this formula, I can get an incorrect number of days when I try to subtract one from the other.What formula can I use to convert my YYYYMMDD field to a format that will allow me to compare number of days between two dates?
Hello all,
Can some one help me with this issue. It seems to be a common question and I have tried a lot of options but nothing seems to work for me.
I have a text box and this is linked to ajax calendar extender. They get a date and I am inserting/updating the date in a sql 2000 database using a stored procdure.
This is the code I use to grab the data from my web form
If txtTrimsEntryDate.Text = String.Empty Then
_oTrim.TrimsEntryDate = System.Data.SqlTypes.SqlDateTime.Null
Else_oTrim.TrimsEntryDate = CDate(txtTrimsEntryDate.Text)
End If
If txtEstCompletion.Text = String.Empty Then
_oTrim.EstCompletionDate = System.Data.SqlTypes.SqlDateTime.Null
Else_oTrim.EstCompletionDate = CDate(txtEstCompletion.Text)
End If
If txtProjectClosedDate.Text = String.Empty Then
_oTrim.CloseDate = System.Data.SqlTypes.SqlDateTime.Null
Else_oTrim.CloseDate = CDate(txtProjectClosedDate.Text)
End If
_oTrim.InsertOrUpdateAProject()
This is the code for the stored Procedure
Dim oSql As clsSqlServer = Nothing
oSql = New clsSqlServer(AppSettings(_dbName))oSql.AddParameter("@projTrimsEntryDate ", _trimsEntryDate, SQLDataType.SQLDateTime, ParameterDirection.Input)
oSql.AddParameter("@projStartDate", _startDate, SQLDataType.SQLDateTime, ParameterDirection.Input)oSql.AddParameter("@estCompletionDate", _estCompletionDate, SQLDataType.SQLDateTime, ParameterDirection.Input)
oSql.AddParameter("@closeDate", _closeDate, SQLDataType.SQLDateTime, ParameterDirection.Input)
Now when it inserts or updates if the value is null then it inserts "01/01/1900" in the database. I want the value to be Null in database.
Is there a way to do this.
