What's the maximum number of characters that varchar field will take? I read somewhere that it's 8k, but I may have misunderstood.
I have to potentially store 100k+ chars in a field.
What's the best way to do this?
Thanks,

I have an overloaded method in my data access layer that I use to load the parameters into a command object. One of these overloaded methods is as follows:
public void LoadSqlParameter(string name, string value, ParameterDirection direction){ param = new SqlParameter(); param.ParameterName = name; param.Value = value; param.Direction = direction;
param.SqlDbType = SqlDbType.VarChar;
cmd.Parameters.Add(param);}
Will using a SqlDbType of VarChar cause me any problems if the actual parameter in the stored procedure is a Char?
Am I better off leaving out the line that specifies the type?
Thanks
hi all, I'm after a way to produce a single-lined output of a char/varchar string replicated over 8000 times.
basically I've been given a task to create a stored procedure which can accept any integer to replicate a string X times.
From what I've read the replicate() fn will covert to varchar of max 8000 bytes.
I've thought about creating a UDF to accept the varchar and int and run a loop to keep outputting but 'print' will pass an endline to the buffer which is no good for my loop.
Any help would be great on this. Thanks.
I need to strip some puntcuation from any field in a given table.I'd rather like to avoid using the replace () for each field in thetable.Anyone have a nifty way do this?Is there a special name that I can use in the replace that means theentire row?(other than syntax, something like REPLACE(@ROW,CHAR(39),'') )tiaRob

Hi there - I would like to share this strip of code with our SQL 2000DBA community. The code below strips all non-numeric characters from agiven string field and rebuilds the string.

View 1 Replies View RelatedHello,
I have a table in SQL Server 2000 which has few triggers. When I try to update a record in that table, I get following message:
Warning: The table '[TABLE_NAME]' has been created but its maximum row size (17275) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
where the data I am updating is well less than the field limit. The triggers are stored in syscomments table and when I dropped these triggers, the update statements were executed without this message. Is there anyway I can change the data type of field text in syscomments from nvarchar to ntext?
Thanks

Hello,
I need to strip out all alpha chars and spaces in a given field and return only the numbers.
I've tried =CInt(Fields!Info.Value) and get an unexplained error. If the data was formatted consitantly I could simply do a RTrim or Right, but the number strings are not the same, some have spaces as in phone numbers (1 800 555 1212) or don't have a leading 1. Most instances are correct for my purpose (8005551212).
Any help would be appreciated.
UPDATE: Using the Replace function =Replace(Fields!Info.Value, " ","") gets me almost there. Now I should be able to use a Right, 10 function to return my desired value. Is it possible to combine these two funtions together?
Say I have a column called 'NAME' in a table called 'CLIENT' and the values in NAME are Surnames or company names like:
NAME
----------------------
1-FOR-ALL
A.B. SMITH (TOOLS LTD)
BROWN
THOMSON
VW CAR SALES
I want my select to return the first 3 characters, excluding special characters (only characters between 1 and z).
In example, the following would be returned for the data above:
NAME
----------------------
1FO
ABS
BRO
THO
VWC

Hello,
I have a table with a column that is currently a varchar(50), but I want to convert it into an int. When I try to just change the type in design mode I get an error that conversion cannot proceed. When I look at the field it appears some of the entries have special characters appended at the end, I see a box after the value.
How can I remove all speical characters and then convert that field to an int?
Also I tried the following query which did not work as well, same error about conversion.
UPDATE myTable SET field = CAST(field AS int)
Hi,
I am very new to using SSIS.
Trying to import data from MS Access 2000.
I receive the error "
[OLE DB Destination [1907]] Warning: Truncation may occur due to inserting data from data flow column "GENDER" with a length of 255 to database column "GENDER" with a length of 2. " on the source flow.
I have done some googling and came up with this post: http://torontosql.dotnetnuke-portal.com/Default.aspx?tabid=32233 which I thought may help, but it does not.
The query against the access datasource features the column: iif([sex]=1, 'm', 'f'). I tried using left(..., 2) as well, but SSIS is determind to treat the field as 255 characters for some reason.
I don't even particualrly care that the field is 255 chars and the sources is only two, I just want the data in! I have other fields coming up with similar error.
Can someone please advise?
PS, what is th significance of the "External Columns" Vs "Output Columns" on the Input and Output Properties tab in Advanced Editor?
I am really struggling with SSIS, it is not as intuitive as DTS.
Hi guys
I need immediate help with a query that I am trying to write. I want to sum the values in a query but the field has a type of varchar and it has decimal numbers too. So if I do the query something like that, that converts the field to int, I get the error message.
I tried converting it into real or float but I get error message on that too. I need help with adding the calculatedValues and getting there sum. I would appreciate any help with that.
Thanks
-Sarah
Select SUM(Convert(int, calculatedValue))
from monitor.dbo.monHistory
where LocalTimeWithoutDst > '8/26/06' and LocalTimeWithoutDst < '8/28/06'
This is the error message I recieve:
Conversion failed when converting the varchar value '274.2' to data type int.
After reading Dan Guzman's blog entry (http://weblogs.sqlteam.com/dang/archive/2008/02/21/Dont-Bloat-Proc-Cache-with-Parameters.aspx) I started modifying some of my code to try it out and ran into a stumbling block. What size would you specific for a varchar(MAX) field?
Since a varchar max field can hold up to 2 billion chracters I really don't think I need to specify 2 billion as the size. Anyone have any ideas?
I have a varchar column which containd comma delimited values like
Rec# Fruits
1 Apple, Peach, Strawberry
2 Orange, Mango
3 Banana, Grape
...........
Now i have to add search facility so that a user could search for more than 1 fruit at a time. I have a Stored Procedure which returns records from this table. that SP has a Parameter @SearchFruit Varchar(500) and the user could pass in values like 'Apple, Mango' to this parameter.
Now how should i write the SQL so that i get back the records Rec# 1 & 2 since apple is there in 1st record and mango is there in the 2nd ??
I know if a put the comma delimited values as individual records in a temporary table and also do the same for the parameter values then i can get the desired results. But i want to avoid doing that. Any other way ?
Thanks

I'm importing data from a text file into SQL as a varchar, and I'm leaving it a varchar in its final destination table. It is essentially a price, i.e., $25.65. I'm using this price field (varchar) to perform a calculation...
Everything seems to work OK, but I'm not sure about using this varchar field to perform this calculation. Is this doable, or should it absolutely be converted to say, decimal?

I am setting up a database that will receive a lot of data from twoseparate telephone centers, the log table will in a short time haveover 1 million lines, and I was wondering if I should use 1 identifyfield or two:case 1:[Id] [int] IDENTITY (1, 1) NOT NULL[ServerId] [int] NOT NULLcase 2:[Id] [varchar(20)] IDENTITY NOT NULLWhere in case 1 I would just use a combination of Id and ServerId toidentify the line, where in case 2 I would have the Id field a varcharthat would look something like A-000001, A-000002 for server 1 andB-000001, B-000002 for server 2Which solution will be faster when searching for a record when thewill have over 1 million lines?

View 4 Replies View RelatedI am trying to load a field in my DB and it is defined as varchar(11) but when I populate it, it still adds spaces at the end. When I try to use it in an If statement, it doesn't match and executes the else instead. The wierd part is it seems to make it 10 characters long and not 11 or the the actual length. I think I had originally set it up for char(10) then changed it afterward but I even deleted the field and reentered it as varchar(11).Thanks,Eric

Hi,
I have to change a due_date field with a varchar(10) to a datetime. I created a new table with datetime but when I imported data into the table it errored out due to the datatype. A varchar(10) going into a datetime(8).
Is there way to resolve this without losing data?. or how do you result this problem?.
Thanks for your help,

Hiya!
I'm having a problem updating a varchar(4000) column in Enterprise Manager when I open the table and try to update one particular row directly. Most of my rows have approx. 100-500 characters in this column, and I can update all of them them, but one row which has 1976 characters in this varchar column doesn't let me change data by typing directly into this column, although it will let me update other columns in the same row. Altogether, my row size has a max. of approx. 5000, below the 8060 limit, so I doubt that's the problem. What Is?
Thanks,
Sarah

We have a small table of about 13 million rows that needs altered. A column in the table needs to be changed from a varchar(20) to a varchar(500). When we ran the alter table script, 3 hrs later and it wasn't done running. Any suggestions on what we can do to speed up the process?
Thanks ahead of time

We are running SQL Server 2000 and the db at the time was running in simple mood
