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?
Hopefully, someone can help me. I am working with a database that contains multiple fields within the tables that are being used for Clinical notes. The fields are defined as VARCHAR(3500). But when I try to extract data (either through Query Analyzer or Crystal Reports), only the first 256 characters are displayed. I ran a query to give me the length of the maximum entry size which returned 2722 characters, yet only 256 are displayed.
How do I go about extracting ALL of the data from this field? Any help is much appreciated.
I am begginner at best so I hope someone that is better can help.I have a stored procedure that updates a view that I wrote using 2cursors.(Kind of a Inner Loop) I wrote it this way Because I couldn'tdo it using reqular transact SQL.The problem is that this procedure is taking longer and longer to run.Up to 5 hours now! It is anaylizing about 30,000 records. I thinkpartly because we add new records every month.The procedure works like this.The first Cursor stores a unique account and duedate combination fromthe view.It then finds all the accts in the view that have that account duedatecombo and loads them into Cursor 2 this groups them together for datamanipulation. The accounts have to be grouped this way because aaccount can have different due dates and multiple records within eachaccount due date combo and they need to be looked at this way aslittle singular groups.Here is my procedure I hope someone can shead some light on this. Myboss is giving me heck about it. (I think he thinks Girls cant code!)I got this far I hope someone can help me optimize it further.CREATE PROCEDURE dbo.sp_PromiseStatusASBEGINSET NOCOUNT ON/* Global variables */DECLARE @tot_pay

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.
I have a SSIS package, and inside it I do something like below:
1. I have a SQL component, to give back a object to store the records. 2. I have a VB script component, I direct the object I got in 1 step into the script as a dataset.
My problem is: I run the package in the SQL SERVER 2005 Store Procedue like this:
do dtexec.exe package.dtsx loop untill i>t
I control the it runs 30 times. But I found that the speed is slower and slower. the first time, it takes about 600 s, but the last time, it takes the 1800 s.
Why? The package don't drop the object it create during the loop in the Store Procedue ? Thanks!
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
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?
Hi,What is the maximum character a text type column can contain ? Can'tchange the length to upper than 16....What is the bigger ? Varchar(8000) or Text ?Regards
Hi all iam trying to but a varchar variable into a TEXT var but i get this error "The assignment operator operation cannot take a text data type as an argument"
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

I am trying to change a text field into a varchar 8000. I get his error message when trying to convert.
Unable to modify table. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot create a row of size 8317 which is greater than the allowable maximum of 8060. [Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.
Anyone know of a way to either truncate the text field or to select only those that are over the 8000 character mark?
Please, i have a big db with a "VarChar" field (8000 char) and now i need more "space". I can use "Text" but how i can convert all my data? If i try to change from the Enterprise Manager i loose all data!!!!
Hi, all I am seting up a table with email message, I am wondering what is the max length for varchar field. I am so reluctant to use text field, since when I run query for the descriptiona in sql analyzer, text field cannot be fully display in column. Any tricks to share? Thanks Betty
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!
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.
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!!
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
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.
When I change a column from text to varchar using thedesign view of a table within Enterprise Manager thevarchar value (less than 8000 characters) appears in thecolumn but does SQL Server automatically delete the textvalues from their pages?If not are they removed by routine reindex/defrag orshould I create a new table, import from the text asvarchar and drop the old table to make sure the pagesstoring the original text version of the values aredeleted?..
I have the following code tha imports the contents of a text file into a varchar(max) field.
Unfortunately the CR/LF are stripped out when I look at the field.
How can I preserve them?
