Hello,
Can someone tell me how to insert text into a table containing a TEXT field?
How to update?
I would like to create a stored procedure that take a text parameter and
inserts it into a new column in my table. Then do the same stored procedure
but this time to update the TEXT field.
HELP!
YamaInsert is simple.
INSERT table_name(int_column, text_column) VALUES(1, ' ... really long text
... ')
Update is a little trickier. In the apps I write, I pull out the whole
value, let the user edit it as a whole, and write the whole value back. As
you might know, you can't append to a TEXT column (so you can't do UPDATE
table_name SET text_column += @.varcharParam), and you can't even manipulate
it locally because you can't have a local variable of type TEXT.
If you are adding things to the end of a text column, you might consider
having a separate related table with comments. That way you can track them
separately, and you don't have to worry about concatenation.
The only time I would ever update is if I have to a batch search and replace
on all rows, e.g. see http://www.aspfaq.com/2445

Are you sure the INSERT will work even with more than 8000 characters?
I thought you had to use the WRITETEXT command?

Yes, though it depends from where it came. Some providers / clients will
truncate because they don't know how to deal with >255 or >8000.

I've never used the WRITETEXT command in production systems. www.aspfaq.com
stores articles in a TEXT column and I have no problems using INSERT /
UPDATE through a web interface. All I can suggest is that you keep your
drivers up to date (e.g. MDAC 2.8) and test your environment before taking
my word for it.

Here is how I settled doing it.
In my ASPX web page I have four fields. A dropdown with a list of all the
letters, a checkbox for activating a letter or setting it to innactive, a
text box for the description of a letter, and another text box for the
letter with multiple line enabled. Hope you like this... :-)
--The table:
CREATE TABLE [dbo].[tblLetter] (
[LetterID] [numeric](9, 0) IDENTITY (1, 1) NOT NULL ,
[Letter] [text] COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Description] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Active] [bit] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
--The stored procedure:
CREATE PROCEDURE SaveLetter
@.Description VARCHAR(100) = '',
@.Active BIT = 1,
@.BlobLetter TEXT = '',
@.blnInsert BIT = 0,
@.LetterNumber INT = NULL,
@.blnDelete BIT = 0
AS
DECLARE @.s BINARY(16)
IF @.blnInsert = 1 AND @.blnDelete = 0
BEGIN
BEGIN TRAN
DECLARE @.ID INT
INSERT INTO tblLetter
(Description, Active, Letter) VALUES (@.Description, @.Active, @.BlobLetter)
SET @.ID = @.@.IDENTITY
SELECT @.s = TEXTPTR( Letter )
FROM tblLetter
WHERE LetterID = @.@.IDENTITY
WRITETEXT tblLetter.Letter @.s @.BlobLetter
COMMIT TRAN
END
IF @.blnInsert = 0 AND @.blnDelete = 0
BEGIN
BEGIN TRAN
UPDATE tblLetter
SET Description = @.Description , Active = @.Active
WHERE LetterID = @.LetterNumber
SELECT @.s = TEXTPTR(Letter)
FROM tblLetter
WHERE LetterID = @.LetterNumber
WRITETEXT tblLetter.Letter @.s @.BlobLetter
COMMIT TRAN
END
IF @.blnDelete = 1
BEGIN
DELETE FROM tblLetter
WHERE LetterID = @.LetterNumber
END
GO
