Text And Varchar (max)

Dec 10, 2006

Hello, I have read that microsoft is getting rid of the text datatype and replacing it with varchar. The maximum that varchar can hold is 8000 bytes. Is there a way to get above 8000 bytes without using text?

Replace Text In Text, Char && Varchar Fields All At Once?

Jan 22, 2008

I have followed many tutorials on selecting and replacing text in text fields, varchar fields and char fields, but I have yet to find a single script that will to all 3 based on field type. Let's assume for a moment that I don't know where all in my database a certain value that I need changed resides ... i.e., the data's tablename and fieldname. How would I go about doing the following ... or more importantly, is this even possible in a SQL only procedure?1) Loop over entire database and get all user tables2) Loop over all user tables and get all fields3) Loop over all fields and determine the field type4) switch between field types and change a string of text from 'a' to 'b'Please be gentle, I'm a procedure newb.

Text Vs. Varchar

Aug 14, 2007

I have a table with a column of varchar(4000) and another table with 2 columns that are varchar(2000)
 Is it better to make these columns text columns? 
 The 2 varchar(2000) columns do not need to be searched, but many of the other columns in that table do need to be searched.
The varchar(4000) column has a full text index on it.
 Any help would be appreciated
Thank you

Blob Text Or Varchar?

Jan 10, 2002

hi everyone a question for all you wise men out there! ;-)

i run a db with thousands of reviews, interviews, article and so on. What's better: 1) leaving all the articles on .txt files and then using the file system object to show them in the page; 2) insert the articles in the db splitting them in several varchar fields 3) insert the articles in the db using the text/blob fields

thanx, it's a very hard question for me!

VARCHAR(3500) Slower Than TEXT?

May 9, 2005

I have a table in which 2 of the fields are defined as TEXT. It was determined that neither of these fields would have to hold more than 3500 characters, so I changed both fields to VARCHAR (3500). The problem is that any query against this table takes 20 seconds to run. When the fields were defined as data type TEXT, queries ran lick-itty-split!? I would have expected just the opposite. Can someone explain this behavior?

Cannot Export Large Varchar To Text File

Jun 15, 2001

When using DTS (in SQL 7) to export via OLE DB a large varchar to a text file, it clips it at 255 chars.
No other data access drivers seem to work, either. This is lame! I cannot use bcp as a work
around, because i want to use quoted comma-delimited, which it doesn't support, and I
am using query-based export, where the query calls a stored proc, which bcp also doesn't
support.

Are there any new versions of MDAC that fix this? Anyone know a workaround? My current hack fix
is to split my field into 2, but this is a grubby fix that hassles my reciptients.

This is a pretty fundamental limitation to a major product!

VARCHAR And TEXT Field Errors - Limit 255 In 7.0?

Mar 27, 2000

We're connecting to SQL Server 7.0 (sp2) via ODBC for our ASP application, and are having trouble saving information collected in a <textarea> tag on an HTML form. I assume the <textarea> tag contains data of type TEXT. i thought there would be no problem in converting it into a string and saving it in a VARCHAR field in the database. this works fine as long as the string is 255 characters or less. anything over that give me an "Errors Occurred" SQL Server error. the field that i'm saving this into is a VARCHAR length 8000. i thought SQL 7.0 had gotten rid of the 255 limit on varchar - could this be an ODBC driver problem (on my web server i currently have 3.50.0305) and/or should i install service pack 2 on my SQL Server? anyone advice would be much appreciated.

thanks,
matt

Optimization Gurus: Help With Varchar Vs. Text Fields Decision

Dec 16, 2007

Hi, I'm trying to improve performance for a db that stores messages.  The message is currently stored in an ntext field, but when I look at all the records from the past 3 months, I found that 88% are less than 1000 characters, and 97% are less than 3000 characters.  I don't want to actually limit the message size, but it seems like I might get much better performance using a varchar(3000) field to hold most of the messages, and a separate text field just used for those 3% that really are long. Is this a good idea?  If so, is it better to put the Message and LongMessage fields in the same table; or, have a separate table to hold the long messages?  If it is in a separate table, it would need to be left joined with the message table each time messages are retrieved.Also -- I am getting about 700 new messages daily, and right now have over 150,000 messages stored.  The vast majority of activity involves new messages.  Is this a good situation to look at using horizontal partitioning?Thanks for any help, I don't really have anyone to discuss this with and it is really helpful to get some other views!!

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.

T-SQL (SS2K8) :: Extract Quoted Text Elements From Varchar Column

Nov 18, 2014

I need to extract specific text elements from a varchar column. There are three keywords in any given string: "wfTask," "wfStatus" and "displayReportFromWorkflow." "wfTask" and "wfStatus" can appear multiple times, but always as a pair and will each be followed by by "==" (with or without surrounding spaces). "displayReportFromWorkflow" is always followed by "(" and there can be spaces on either side. The text elements will be between a pair of double quotes, and following one of keywords. For each row, I need to return the task, status and report name.

declare @t table (rowID int, textValue varchar(1024))
insert @t
(rowID, textValue)
values

[Code] ....

Output:
rowID, Task, Status, ReportName
----- --------- ------- ------------------------
1, Issuance, Issued, General Permit
2, Issuance, Issued, Capacity Letter Type III
2, Review, Denied, Capacity Letter Type III

I started with a string splitter using the double quote character, referencing elements "i" and "i+1" where the text like '%wfTask%' or '%wfStatus%' or '%displayReportFromWorkflow%', but the case of multiple task/status in a row has confounded me so far.

Unfortunately, CLR is not an option.

Trying To CONCAT A TEXT Field With 2 VARCHAR Fields - Brick Wall.

Dec 7, 2006

Hi all. I have been going round and round for the past 2 days on this and would appreciate any help. In a view select statement, I need to concat 2 varchar fields with a text field. If I CONVERT the TEXT field to VARCHAR, only the first 30 characters of the field appear in the result set. If I convert the VARCHAR fields to TEXT, I get an error that I cannot CONCAT TEXT fields. I'm not sure what to do. Can someone please offer some assistance? Thanks in advance! Steve
