Hi I have a table, which contains Char and NChar NOT NULL columns
Now I need to change it to NULL, when I use the following command, it fails for the following error,
The command I used,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> CHAR NULL
ALTER TABLE <TableName>
ALTER COLUMN <ColName> NCHAR NULL
Msg 8152, Level 16, State 13, Line 1
String or binary data would be truncated.
The statement has been terminated.
But for the same table, the below command executes fine,
ALTER TABLE <TableName>
ALTER COLUMN <ColName> SMALLINT NULL
Also I can change the NULLABILITY from NOTNULL to NULL using Enterprise Manger, editing the table using Table Design and selecting Allow Nulls option.
I am trying to convert a single code page MS Server database into a unicode database, using the unicode data types,NCHAR, NVARCHAR, NTEXT. The problem is that in the original database, indexes and constraints have been defined on the tables whose configurations need to be changed. As a result, the ALTER TABLE command fails. Are there any other alternative solutions? Also, data from the old database needs to be preserved. The objective is to create a unicode database which keeps the old data intact as well as accepts the new data in unicode. It would be great if you could help! Thanks, Sheetal.
can anybody please explain me why microsoft using nvarchar/nchar instead of varchar/char in northwind database and pubs database. I know if a column holds unicode data you should use nvarchar or nchar but for me all those tables in northwind/pubs are not holding unicode data. but still why microsoft settled for nchar/nvarchar.
Could someone please help me by explaining which one is best to use and when? For example, storing the word "Corona Del Mar" - which Data Type would be suggested? Thanks.
Hi, We are in process of converting all of the data type of the fields from CHAR/VARCHAR/TEXT into NCHAR/NVARCHAR/NTEXT (DBCS). Having more than 900 store procedure its look like real pain to make modification in all of the SPs.
After failed to find any help from GOOGLE, I am posting this request. I am basically looking for any automated tool which are convert data type in SP based on the field of the table used in the SP. Or at least which can provide me some sort of list which can helpful for doing manual reactoring.

#1 This stored procedure can be used to search and replace substring in the char, nchar, varchar and nvarchar columns in all tables in the current database. You should pass the text value to search and the text value to replace. So, to replace all char, nchar, varchar and nvarchar columns which contain the substring 'John' with the substring 'Bill', you can use the following (in comparison with the SetTbColValues stored procedure, this stored procedure replace only substring, not the entire column's value):
I am having difficulty constructing a where clause. I have 4 columns in a table. Col1 is never NULL. Col2,3,4 may or may not contain NULL values. Here is the situation.
1. Col2,3,4 are NULL WHERE Col1 = condition
2. Col2 is NULL, 3 may or may not be NULL. When Col3 is NOT NULL, Col4 may or may not be NULL
where col1 and (col3(Not Null values) OR Col4(Not Null values)) = condition.
I accidently put char instead of datetime in the Sql Server DateCreated dataType. Is there any way that now I can change. I guess even if I change I cannot get the time and date in a format that I want since they are in Char datatype.

Hello all, I'm using SQL Server 2000 and have about 250 stored procedures that use an EMPLID parameter or variable of type varchar with a length of 4. I need to change the length to 10 instead and would like to do so without having to open every sp for editing. Is there a way to do this through SQL Server 2000? Does anyone have a script to do this? Any help would be appreciated.
A SQL table has a field named "pay-day" with Char(8) data type.
I tried to change its data type to datetime but only with an error message like this. I did right-click the table and tried to modify a data type.
- Unable to modify table. The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value. The statement has been terminated.
Hi everyone!I am working with Delphi v7 and MS SQLServer.I am trying to insert data in a table with a SQL sentence. Some of thefields of my table are type char or varchar, and they can have nullvalues.żWhat do i have to write in the SQL sentence to insert a null value inthose fields?I tried with '', an empty String, but it doesnt work, the tablesstores an empty String (logical :-)).In the SQLServer GUI you have to press CTRL + 0 to insert a NULLvalue, but how can i tell this to the SQLServer through a SQLSentence?Well, thank you very much.
Hi, What is the difference updating a null value to char/varchar type column
versus empty string to char/varchar type column?Which is the best to do and why? Could anyone explain about this?

I put a blank or ‘0’ in one of column of a text file and then I used BCP to load this file to a table of SQL server 6.5. The field in SQL server table is char type with size 1. After I run this process, all rows with this column received ‘0’ and no blank or null at a black value place. Could you please help me to fix this problem and make some of rows in the column get a blank or null value.
i'm going nuts with this, i suppose i will crack it eventually, but i thought i'd ask around here, seems like all the smart SQL Server guys hang out here
(i'm an SQL guy, not an SQL Server guy)
how does one place 5 spaces into a CHAR(5) column? create table testzeros ( id smallint not null primary key identity , myfield char(5) ) insert into testzeros (myfield) values (' 1') insert into testzeros (myfield) values (' 11') insert into testzeros (myfield) values (' 111') insert into testzeros (myfield) values (' 1111') insert into testzeros (myfield) values ('11111') insert into testzeros (myfield) values (' ')
select id , myfield , len(myfield) as L from testzerosno matter what i do, id=6 shows up with L=0, just like an empty string
i've even tried inserting 4 spaces and a non-blank character, which enters just fine, just as you would expect, but when i update the value and replace the non-blank character with a blank, all 5 spaces collapse back to an empty string
is there some kind of server setting like SET ALL_SPACE_EQUALS_EMPTY_YOU_IDIOT to OFF or something?
I have a column in my db which is char(40). There are entries in this with the same text, but some come up with a length of 24 and some 25. This sugggests to me that there is a blank trailing space. Am I right?
However, if I update it to iteslf using a Rtrim, nothing changes.
Is is something to do with ANSI padding?
How can I get these entries to be identical, please?
I have a char(11) for SSN, and I would like to default it to123-45-6789 so I can avoid having nulls in this column, and so I caneasily find the rows in which I need to have a 'correct' SSNentered/updated.I tried using just 123-45-6789, and SQL2005 doesn't seem to bedefaulting to this value, it seems to be keeping it as(((123)-(45))-(6789), and not placing it into this column when a newrow is created....Is there some special way I must specify defaults for a char(11) field(Yes, I will include the dashes).Thank you,Tom
Hello everyone, I have searched and seached for an answer to something that I know has to be simple but have been unsuccessful. I appreciate any help...

I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

I have an Excel spreadsheet (Excel 2003 format) with a column of values. The column is formated to General (although I've tried it formated to text). The values are alphanumeric. However, there are a few values that are completely numeric.
Example:
_ITEMNUMBER_
1-528
K214-5
184PR
45678
As can be seen, the last value is completely numeric. I am importing into a table with one column that is formated as nvarchar(50).
I use dtswizard.exe and do a simple import into the table and the alphanumeric values import just fine but anytime a value is completely numeric it has a NULL value in the table instead of the value that should be there.
I've tried changing the format of the column to nchar, char, etc, etc. Always comes in NULL.

I am working with Excel, then within Excel I am using MS Query to query a database. I am trying to use the CAST function on a field with numbers (1,2 or 3 digits) so I can convert it to a text value with three digits, i.e. 1 would read 001, 12 would read 012, etc.
I am not using CAST in the design grid. Is this even possible?
I am modifying the underlying SQL code. Here is the line that is giving me trouble:
CAST(GL02GLF.GLF_SEQ_NUM as CHAR(3)) as “Sequence”
