255 Character Strings?

Posted on 2002-07-23
Last Modified: 2013-12-03

I'm told PHP has no problems with long strings, however, if I attempt to retrieve a 2000 character long string from an MS-SQL database, I'm only shown the first 255 characters of it.

Is there any reason to this at all?  How do I over come this problem?

Thanks for any help you can give,

Can you confirm that more than 255 characters are stored in the database field? What field type is being used.

There is a function you can get the type with ...

string mssql_field_type ( int result [, int offset])


echo mssql_field_type($results,0);

would show the type of the first column in the result set.

You may find that the field is set to be a small text field of some type, so only 255 characters are being stored.

Try using another client to get the data out, maybe something like MSQuery or even Excel/Word via ODBC, or something, so you can see the data.

Hi Richard,

If I do this:


I get Char 255 - which it's not.  It's a char(2000).

If this is the case, should I change data types on MS-SQL?  If so, what should I be using?

Thanks for the info,

Just to confirm, can you try the that test on a result where you know the data is LESS than 255, just to make sure that the test is NOT giving you the length of the data and the length of the field.

I am not up on the text types of MSSQL, but try varchar(2000) or text(2000).

Hi Robert,

I changed the data type to text and it worked perfectly!  Thank's very much for that!
