If I have a field where 99.9% of the time the answer is going to be "No", would I be better, in terms of disk space, using:
A bit field
OR
A tiny int field, with a NULL for the 99.9% that are "NO", and a 1 for those that are "YES".
I'm using SQL Server 7.0.
My application developer has no preference.
Thanks.

hi all,
i have an autonumber field (primary key) and another integer field as part of a table. What i want to do is when a record is created, the default value of the integer field should be the_autonumber+1000 for eg record with pk 82 will have an integer field that's automatically 1082. Would it be possible to do this ? Thanks in advance.

I have a field ID of type integer, I want to put two numbers in that field: 3 and 7, so what I do is just store the number 37.Now, is there a command in SQL server which checks if the ID field contains a number I look for, say 7.Something like a CONTAINS keyword...If there is, could someone please tell me what it is AND tell me a bit more about it :memory usage, (dis)advantages etc.

Hello,
I am trying to write an SQL command to set the default value of an integer column I have within a table.
ALTER TABLE TableName alter column ColumnName int default 0
Any suggetions?
We have account numbers that are string values, looking like: "01.02.02.00.0040.000.000".
We need to parse individual segments and pull out a range of values treating the segment like an integer. For example we would like all accounts that have the fifth segment ranging in values from .0040. through .0060. inclusive.
We've been trying to do something with the like clause: LIKE '__.__.__.__.[0-0][0-0][4-6][0-0]'.
We want 40 through 60 but we're getting 40, 50, and 60. If we change the last bracket to [0-9] we get 40 through 69.
Does anyone have any suggestions as to either fix our like clause or another approach?
Thanks.

I am facing problem with re numbering of field records in a table.I am having one table with below records.
sid(identity/primarykey) stickyId(Integer) UserId(integer)
102 0 171
103 1 171
104 2 171
105 3 171
here how to renumbering stickyId values when deleted particular stickyId from UI. Here stickyId field is Integer type only. not primarykey/identity field.
I’m looking for feedback on the Best/Right way to Insert nulls into SQL dateTime field in SQL DB from a web UI textbox.
Option 1: Presently implemented:
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", System.Data.SqlTypes.SqlDateTime.Null, dtDateFollowUp.Text)
Although ithis does what is needed it generates the following inner exception
ParamValue {System.Data.SqlTypes.SqlDateTime} Object[System.Data.SqlTypes.SqlDateTime] {System.Data.SqlTypes.SqlDateTime} System.Data.SqlTypes.SqlDateTimeDayTicks
<error: an exception of type: {System.Data.SqlTypes.SqlNullValueException} occurred> Integer IsNull True Boolean
Option 2:
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", System.DBNull.Value, dtDateFollowUp.Text)
No exceptions, no problems that I have seen yet.
Option 3:
Dim dtNull As System.Data.SqlTypes.INullable
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", dtNull, dtDateFollowUp.Text)
No exceptions, no problems that I have seen yet.
Any advice would be greatly appreciated!

I have the folliwing two fields, want tp concatenate:
=Fields!sequenceno.Value & =Fields!LogType.Value
Thank you very much for the information.
Currently I have the following stored procedure which simply adds a new row in my SQL Express 2005. What I want is that -1). before inserting the record find out the new ID (primary key) value. (ID is automatically a sequential integer generated by SQL Server)2). and set COMPANY_ID = (new) ID Any thoughts? Thanks ALTER PROCEDURE usp_tbl_Company_Insert @Company_ID int, @Name varchar(200), AS<FIND THE NEW ID of the new row in the database> @Company_ID = (new ID) INSERT INTO tbl_Company (Company_ID, Name,)VALUES (@Company_ID, @Name)
View 1 Replies View RelatedWorking on a new database where the Date and Time are stored in a Date Time Field.
Then working on an OLDER database file within the same SQL Database contains these 2 items as integers:
transDate = "71615" (July 16, 2015)
transTime = "12345" (01:23:45 AM)
How do we convert both of them into a single SQL DateTime field such as "2015-07-16 01:23:45.000" so that it can be used in a join restricting to a date time in a different SQL File that properly has the DateTime in it?
This works well for converting the transDate Part in the select statement:
dbo.IntegerToDate(at.transDate) as transDate
* That returns: "2015-07-16 00:00:00.000"
* The resulting data must work directly in a Microsoft SQL Server Management Studio Query using either using the "on" statement or part of the "where" clause. In other words, NOT as a stored procedure!
Also must be able to be used as a date difference calculation when comparing the 2 files Within say + or - 5 seconds.
When i do a select on my emplee table for rows with null idCompany i dont get any records
I then try to modify the table to not allow a null idCompany and i get this error message:
'Employee (aMgmt)' table
- Unable to modify table.
Cannot insert the value NULL into column 'idCompany', table 'D2.aMgmt.Tmp_Employee'; column does not allow nulls. INSERT fails.
The statement has been terminated.
This sux
is there an elegant way to use one equals sign in a where clause that returns true when both arguments are null, and returns true when neither is null but both are equal and returns false when only one is null?
View 4 Replies View RelatedI have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.
I'm new to SQL and I'm trying to write a statement to satisfy the following:
If [Field1] contains text from [Field2] then return [Field3] as [Field4].
I had two tables where there were no matching keys. I did a cross apply and am now trying to parse out the description to build the key.
Good morning...
I begin with SQL, I would like to add a field that will be date like 21/01/2000.
Actually i find just "datetime" format but give me the format 21/01/2000 01:01:20.
How to do for having date and time in two different field.
Sorry for my english....

Can someone provide detailed infromation on how to delete NULLS within tables. I'm new o the SQL side so I hope I have explained what it is that I'm looking to do. Our in house programmer said that the NULLS maybe causing a problem with the software communicating with the SQL Server software.

Hi i am new to SQL, and i have a data base thats got NULLS in it
is there a query i can run, which can take the NULL value out ?
anything will be greatly appreciated.
Hi,I don't have any specific details as I do not really understand whythis is happening but we have a customer database that we have beenusing and queries on text fields have begun returning empty stringvalues instead of NULL.So for example:SELECT TAB1.DESCRIPTIONFROM TABLE1 TAB1WHERE TAB1.DESCRIPTION IS NOT NULLORDER BY 1may have returned 50 records in the past (purely an example). It isnow returning an additional record first that appears just to be ''.Now I am not too sure where to begin looking into this. ODBCconnections, collation settings? I just am not sure where to begin.The column will not have had '' inserted into it; therefore it shouldbe NULL.I have posted this mainly so I can see if anybody else has seen thissort of behaviour - I cannot see why this has suddenly happened.The collation setting on our server is different to that of thecustomer DB, but this shouldn't make a difference should it?If anybody has any ideas then I can post some more information.Thanks,Paul

View 6 Replies View RelatedHiI am probably going to regret asking this because I'm sure you are going totell me my design is bad 8-) ah well we all have to learn....anywayI often use Nulls as a marker to see if certain tasks have been completed.A typical example would be a column say invoice_valuewhen new work is entered and a new record is appended, I leave theinvoice_value column as NULL, so if I want a View for uninvoiced work Icheck for the invoice_value being equal to NULL, and alternatively if I wantinvoiced work, I check for not null. I did it this way to save putting inanother column that needed to be set to TRUE or FALSE. (I do similar thingselsewhere aswell)so far everything seems to work OK but reading some old stuff on Google Iget the feeling that NULLS should be left alone, have I done wrong?many thanksAndy
View 3 Replies View RelatedHello all
I have a colunm - Datatype : nvarchar - Contains: Numeric, characters, strings, date and NULLS
I am getting a the value of each row of this colunm in a variable say @var1
Now I am trying to do some functionalities depending on this variable.
The requirement is if this variable is not null I need to do some stuff.
So I write simple query:
IF (@var1 IS NOT NULL)
BEGIN
......
END
when i am doing this I get an Error:
Error converting data type nvarchar to numeric.
realizing this I change the condition to
IF ( LEN (@Var1) > 1)
then
IF (LEN (@Var1) <> 0)
but no use. I get the same error.
I even use cast
I get the error
Conversion failed when converting the nvarchar value 'null' to data type int.
IF(CAST (@OldValue AS INT)IS NOT NULL)
OR
IF(LEN (CAST (@OldValue AS INT)) <> 0)
Can somebody help in guiding the best practice to do this?
Hi All,
If I run "SELECT 610/100", query analyser returns 6! (wrong)
If I run "SELECT 610.0/100", query analyser returns 6.100000! (correct)
I know I can get the correct result by running "SELECT Cast(610.0 as Float)/100", but why doesn't the first example return 6.1?
Is there some setting on my server which says Integer / Integer = Integer ?

Hi,This should be straight forward, but I've searched high and low on the net.I have a FORM which allows me to INSERT data, SQL Server 2005 backend. I populate the all the mandatory fields. But when I click on the Insert button, it won't let me save and says:Column 'PERSONAL_ID' does not allow nullsI'm
using tableadapters, business logic layers etc. and pausing clearly
shows that the values from the form are being passed to the procedure
that I have created "AddNewRecord". And PERSONAL_ID is definitely not
NULL! It fails on Line 971: Me.Rows.Add(row)PERSONAL_ID
is a primary key which I generate. The pause also shows that for
PERSONAL_ID it says " {"Conversion from type 'DBNull' to type 'String'
is not valid."}Function AddNewRecord looks like this:<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _

This produces an ordered list of the parent categories and subcategories from the table as long as there is a subcateogry directly below one of the parent categories.
