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

thanks,

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

When the value is NULL, the size is also NULL

Note that there is no such datatype as text(max)

How did you insert data?

Can you post the code?

This is great!

But how can I find out the MAXSIZE of the field in question?

We have recently updated our DB to increase the size of certain fields. I need to check if the user updated their DB before performing any work on those fields.

Hey Andazi,
Change the query to

column1+column2+cast(column3/100 as varchar(50))

As the cast is only getting the first 20 characters

You guys explained how to change the data amount being returned directly in SQL server, but what about the amount being returned in an ASP page?

UPDATE tab SET col = RIGHT(‘000000′ + col, 6)

By: Brian Tkatch

@ran

Is this a VARCHAR field?

UPDATE tab SET col = ‘00′ + col WHERE LEN(col) = 4;

@Chaminda,

Open SQL Server Management Studio
Go to Tools – Options (Tools exists at the top left of SSMS)
Expand Query Results
Expand SQL Server
Click on Results to Grid

On right side, Set Value for :
Maximum Characters retrieved : Set a higher value.

Because of this, SQL Server is returning fewer characters. Change this value to a higher value and see the difference

I am having the same issue as Ramani. Any solution for this ?
I have a text field and what ever number of characters that I save on that field, it returns only 1001 characters. But when I checked with DATALENGTH() function it shows that it is having the same number of characters that I entered.
