pking,

Thanks for the reply, i have found the solution for the issue.it simple we need to use the below command from sqlcmd to fetch a row having column with more than 10000 characters.

sqlcmd -S 10.11.111.121 -U sa -P abc@123 -d DBNAMe -i ./conf/SQL.Archive_query.conf.sql -o ./tmp/sqlserver/SDS_Archive_Update.ddl -y 0

-y 0 –> Using this option will increase the length of a row

Are you use access database?
if yes then take data type memo.
if you use sqlserver 2005/08 there are no text data type
there you can use nvarchar(max)

ANOTHER USE OF LEN() AND DATALENGTH() ARE :-

SELECT LEN(‘SRI ‘) – 3
SELECT DATALENGTH(‘SRI ‘) – 9

LEN() IGNORES THE SPACES BUT NOT DATALENGTH()

jaheer,
Not sure this helps but in SQL Server 2008 the maximum number of bytes per row is 8,060. This restriction is relaxed for tables with varchar, nvarchar, varbinary, or sql_variant columns that cause the total defined table width to exceed 8,060 bytes. The lengths of each one of these columns must still fall within the limit of 8,000 bytes, but their combined widths may exceed the 8,060 byte limit in a table. For more information, see Row-Overflow Data Exceeding 8 KB in BOL

I am sending the output of a query to a file and unfortunately every row is containing only a certain number of characters. My query has rows having length more than 10000 characters for each row. When I get the query and send it to a file I am seeing only the first 250 characters for each row instead of 10000 characters.

I will be grateful if anyone can help me suggesting a solution for this problem.

I appreciate your help in advance.

i tried this option which is not helping in my case as the max it support is 8192
Go to Tools –> Options –> Results tab. Change the “Maximum characters per column” The default is 256

The problem is not to VIEW the content BUT to insert the whole text. the text is not inserted completely and is truncated…

By: madhivanan

madhivanan — Thu, 28 Oct 2010 08:06:39 +0000

Why do you need this? If you want to view full content, export to text file and view from there

Thanks a lot!

I want to increase the text size in one specific DB. I see that the maximum text field size I already have is around 32,000 characters but text with 40,000 characters was truncated.

How can i increase text size in specific DB or table?

The msdn website shows that len and datalength functions are different.

LEN- Returns the number of characters of the specified string expression, excluding trailing blanks.

DATALENGTH – Returns the number of bytes used to represent any expression.

I have a tabe in oracle which has a varchar field with length of 48. I need to select records that are not in the length of either 8, 15 & 16 size.
The second criteria is to identify records which are not numeric i.e. any character value should be displayed.

Hello,

I have a table which has field1, field2 and field3 columns of type int, the combination of those columns represent 10 digit phone number. I know field3 always have 4 digits, but MS SQL trims the right most 0s. all i am tring to acheive is to provide the user with one field 10 digit number.

here is my query:

INSERT INTO [Info Direct Res new]
SELECT ‘Info Direct’, /* Datbase Name */
DECLARE @MAX_FIELD_LEN int;
DECLARE @fieldLength int;
SET @MAX_FIELD_LEN=4;
SET @fieldLength = len(Cast(field3 as varchar));
cast(field1 as varchar)+cast(field2 as varchar)+RIGHT(’0′,@MAX_FIELD_LEN-@fieldLength)+Cast(field3 as varchar), /* Phone Number */
field5, /*First name*/
field6, /*Last Name*/
ISNULL(field8,”) + ‘ ‘ + ISNULL(field9,”)+ ‘ ‘ + ISNULL(field10,”)+ ‘ ‘ + ISNULL(field11,”)+ ‘ ‘ + ISNULL(field12,”), /* Full Address */
field13, /* city */
field14, /* province */
field15, /* postal code */
‘ ‘
from stcir1001

I get syntax error where i say declare

It is formation issue. If you use front end application do the formation there
