Size To Specify For Varchar(Max) Field

Mar 23, 2008

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?

Convert Field From VarChar To Int With Speical Characters In Field

Aug 29, 2007

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)

Help! Limitations On Varchar Size And Not Being Able To Use TEXT In Stored Procedure

Nov 4, 1999

I am stuck! and need help!

I have a problem I can't seem to find the solution with this aweful limitations on VARCHAR fields of 255.

Within a stored procedure called Store_Check, I need to dynamically build a string (@string) using VARCHAR(255) since the text datatype can't be used in a stored procedure.

So,this string is built according to whether the Store ID is NOT NULL. So if the StoreID is not null, I start building this string 'Exec Update_Store_Address @StoreID1, @address2'. There are 20 StoreID's passed into Store_Check. IF all 20 StoreID's are not NULL, the executed String greatly exceeds 255 because the string winds up looking like this

'Exec Update_Store_Address @StoreID1, @address1 Exec Update_Store_Address @StoreID2, @address2 Exec Update_Store_Address @StoreID3, @address3 Exec Update_Store_Address @StoreID4, @address4 Exec Update_Store_Address @StoreID5, @address5 Exec Update_Store_Address @StoreID6, @address6 etc. etc.'

I am not executing this string within the StoredCheck procedure. It needs to be passed as ONE string to a VB program and it gets executed by the VB program. Even if I create 4 local variables and concatenate them, it stops at the 255th character.

Also, a local varialbe of type TEXT cannot be declared within stored procedure.

What can I do? I am stuck!

SQL 2012 :: Varchar - Changing Text Column Size

Aug 7, 2015

Impact on performance of changing Text column size.

However, many of them were regarding older releases of SQL Server.

Does the architecture in 2012, 2014 releases make this less of an issue ?

In other words, why bother going from Varchar(1000) to Varchar(50) ?

I'm just thinking maybe there is column compression automatically now.

Sum Of A Field That Has A Type Varchar

Mar 28, 2007

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.

Searching In A Varchar Field

Jul 12, 2001

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
Sumit.

Calculation On A Varchar Field

Jan 17, 2005

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?

Varchar And Blank Spaces In SQL DB Field

Jun 30, 2005

I 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

Problem Updating Varchar Field

Nov 29, 2001

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

Import Problem With Varchar(max) Field

Oct 30, 2006

I'm trying to import some Assessor data from a text file into a table and the field for Legal Description (column 2 in the source text file) in the table is of data type varchar(max) because some of the data goes over the 8K size. I get an error on the first row of importing that refers to column 2 (see 'Initial errors' below). I read the related post and changed the size of input column 2 to 8000 and got this error. Finally I set the size of the of input column 2 to 4000 and it ran. So I'm thinking there is a limit on the size of varchar data that can be imported. Just want to clarify what that limit is and how I might go about importing this data.

Thanks, John

Comparing VarCHAR FIELD With NULL

Apr 20, 2006

Hi, I have the following query

SELECT *
FROM PABX
INNER JOIN LOGIN ON (PABX.COD_CLIENTE = LOGIN.COD_CLIENTE)
AND LEFT(LOGIN.TELEFONE1,3) = LEFT(PABX.NRTELEFONE,3)
LEFT JOIN AUXILIAR ON (AUXILIAR.ORIGEM=LOGIN.LOCALIDADE)
WHERE
pabx.COD_cliente = 224 and
SUBSTRING(PABX.NRTELEFONE,4,1) NOT IN ('9', '8', '7')
AND LOGIN.UF = RIGHT(PABX.LOCALIDADE,2)
AND LOGIN.LOCALIDADE <> PABX.LOCALIDADE
AND PABX.CLASSIFICA IS NULL
AND PABX.LOCALIDADE <> AUXILIAR.DESTINO
AND (BLOQUEADO = 0 OR BLOQUEADO IS NULL)



But It has a problem because when AUXILIAR.DESTINO returns null (it means there is no registry) the condition AND PABX.LOCALIDADE <> AUXILIAR.DESTINO doesn't work, like 'SAO PAULO' is different from 'NULL' but for my query no it's not even equal, and this condition ommit the results....how can I solve it ?

PS: Both auxiliar.destino and pabx.localidade is varchar(255)

Thanks
