Text Field Comes Back Blank When Using ADO
Apr 2, 2008
Originally, I hit this problem with PHP. But then I was able to reproduce using VBScript.
I have a table with a couple of text fields, and one Real field in a table. One row of data in the table. Both text fields set, but the real field doesn't even need to have a value set.
Connecting to SQL 2005 using a DSN - ODBC.
I'm using a stored procedure I named ExecIt that runs a SQL statement that is sent in and returns records.
If I use cursor location adUseClient, it returns values for the text fields.
If I use asUseServer, it returns blank values.
If I use a SQL statement directly, it works. Only fails when using SQL statement by way of ExecIt.
In each case, cursor type is adOpenStatic or adOpenDynamic.
Using this combination fo cursor type and cursor location, it mimics what I see in SQL profiler when PHP is using ODBC.
Anyone have a solution?
Table:
CREATE TABLE [dbo].[test3](
[ID] [int] IDENTITY(1,1) NOT NULL,
[text1] [text] COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[text2] [text] COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[real1] [real] NULL,
CONSTRAINT [PK_ReworkLog2] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
Stored Procedure - ExecIt:
create PROCEDURE [dbo].[ExecIt]
-- Add the parameters for the stored procedure here
@Statement nvarchar(max)
AS
BEGIN
exec (@Statement)
END
DSN has been set up through ODBC manager. Can be using 2005 native driver, or older sql server driver.
Code:
dim txtOut
set conn1=CreateObject("ADODB.Connection")
conn1.Open "my-DSN","my-userid","my-password"
sql="exec execit 'select * from test3 where ID=1'"
set rs = CreateObject("ADODB.recordset")
rs.CursorLocation = 2 'adUseServer - 2, adUseClient - 3
rs.CursorType = 3 'adOpenStatic
rs.Open sql,conn1
if not rs.EOF then
txtOut = "Results" & vbcrlf
txtOut = txtOut &"text1:" & rs("text1") & vbcrlf
txtOut = txtOut &"text2:" & rs("text2") & vbcrlf
txtOut = txtOut & vbcrlf
end if
msgbox txtOut
rs.Close
conn1.Close

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:
Code:
IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))
Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table
but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"
thanks

I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("@option", adInteger, adParamInput, 4, update_option)
.Parameters.Append .CreateParameter("@mfg_ord_num", adChar, adParamInput, mfg_ord_num_length, "")
.Parameters.Append .CreateParameter("@mfg_start_date", adChar, adParamInput, 10, "")
Set rs_refresh_shipping_sched = .Execute
End
Please help

I am trying to load a field in my DB and it is defined as varchar(11) but when I populate it, it still adds spaces at the end. When I try to use it in an If statement, it doesn't match and executes the else instead. The wierd part is it seems to make it 10 characters long and not 11 or the the actual length. I think I had originally set it up for char(10) then changed it afterward but I even deleted the field and reentered it as varchar(11).Thanks,Eric

Hi there,
I'm in a bit of a jam here and will appreciate any help.
I need the SQL code to replace a record if the record is empty.
For instance, I have about 7 columns containing over 40K records. In the firstname field, some records are blank. I need to replace all the blank firstname fields with this: 'now invalid' (without the quotes)
What would be the best way to achieve this?
Thanks

I am trying to bcp import a text file into a SQL Server 2000 database.The text file is coming out of a java application where orderinformation is written to the text file. Each record is on it's ownrow, so the last item in each record has a new line character at theend of it to create the next row. This works well in creating the filehowever bcp does not like to import this text file with the extra blankline at the end. If I change the new line character to the beginning ofthe records then there is a blank line at the top of the text file,which bcp also does not like. Does anyone have any suggestions for meto get around this issue?Thanks,

Several textboxes are being on a web form for date entry. and we want to allow the user to leave date fields blank (if particular date is unknown). However, when the field is left blank, the SQL Server 2000 database defaults to 1/1/1900 (datatype = datetime).My question is as follows: How is it possible to leave a date textbox field blank, and either send 00 0 000 or spaces to the SQL Server 2000 database datetime field?Any advice/insight is appreciated!

I'm new to SQL and I'm trying to write a statement to satisfy the following:
If [Field1] contains text from [Field2] then return [Field3] as [Field4].
I had two tables where there were no matching keys. I did a cross apply and am now trying to parse out the description to build the key.

When I open a report definition, go to a dataset and open it, the CommandType ALWAYS goes to "Text". I don't want "Text", I want "Stored Procedure". I NEED "Stored Procedure".
I have also found that the CommandText for a different dataset will change even though I have not opened it.
I guess the only solution I have is to open the RDL files, search for the dataset entries and then fix the XML code. This is a real pain in the buttocks when I am working with 300+ reports.
Is there a fix for this bug? Or are you going to FORCE everyone to use "Text"?
I am trying to finish this project so that we can release it to our customers but now I have to wonder why we decided to go with Reporting Services, especially now that we have to do double edits on each and every report.

Hi,
Im a programmer for an university webportal which uses php and msssql.
When an user creates a new entry and his text is too long the entry is cut short and weird characters appear at the end of the entry.
For example:
http://www.ttz.uni-magdeburg.de/scripts/test-messedb/php/index.php?option=show_presse&funktion=presse_show_mitteilung&id=333
How can I set the text limit to unlimited?
Could it be something else?
Is there a way of splitting an entry to several text fields automatically?
Thanks in advance for any help you can give me,
Chris

In SQL 2005 if i was trying to insert some data with a text qualifier inside a text qualified field, it would work, for example:
"Name","ID ","Location","","Comany",""House Name" Road",
In SQL 2012, this fails with the error message, cannot find the text qualifer for field.
To get around this, we are having to import the data into a Dirty Data column of aTEMP table, ID, Dirty Data, Clean data - perform multiple updates and change the text qualifier and ensure they are only changed in the right places so we can keep the ". In this example, we changed the text qualifier to PIPES.
After these updates, we then export the data from CLEAN data back out to CSV, then reimport it into the origional destination table with a new text qualifer.

Hi,
I'm importing an Access database to SQL Server 2000.
The issue I ran into is pretty frustrating... All Memo fields that get copied over (as Text fields) appear to be fine and visible in SQL Server Enterprise Manager... except when I display them on the web via ASP - everything is blank (no content at all).
I didn't have that problem with Access, so I ruled out the possibility that there's something wrong with the original data.
Is this some sort of an encoding problem that arose during database import?
I would appreciate any pointers.

I am trying to populate a field in a SQL table based on the valuesreturned from using substring on a text field.Example:Field Name = RecNumField Value = 024071023The 7th and 8th character of this number is the year. I am able toget those digits by saying substring(recnum,7,2) and I get '02'. Nowwhat I need to do is determine if this is >= 50 then concatenate a'19' to the front of it or if it is less that '50' concatenate a '20'.This particular example should return '2002'. Then I want to take theresult of this and populate a field called TaxYear.Any help would be greatly apprecaietd.Mark

Hi all,
i've a reasonable amount of experience with MS Access and less
experience with SQL Server. I've just written an .NET application that
uses an SQL Server database. I need to collate lots of data from around
the company in the simplest way, that can then be loaded into the SQL
Server database.
I decided to collect the info in Excel because that's what most people
know best and is the quickest to use. The idea being i could just copy
and paste the records directly into the SQL Server database table (in
the same format) using the SQL Server Management Studio, for
example.
Trouble is, i have a problem with line feed characters. If an Excel
cell contains a chunk of text with line breaks (Chr(10) or Chr(13))
then the copy'n'paste doesn't work - only the text up to the first line
break is pasted into the SQL Server database cell. The rest is not
pasted for some reason.
I've tried with MS Access too, copying and pasting the contents of a
memo field into SQL Server database, but with exactly the same problem.
I've tried with 'text' or 'varchar' SQL Server database field formats.
Since i've no experience of using different types of databases
interacting together, can someone suggest the simplest way of
transferring the data without getting this problem with the line feeds?
I don't want to spend hours writing scripts/programs when it's just
this linefeed problem that is preventing the whole lot just being
cut'n'pasted in 5 seconds!
cheers
Dominic

Hi,I been reading various web pages trying to figure out how I can extract some simple information from the XML below, but at present I cannot understand it.
I have a MS SQL 2005 database with which contains a field of type text (external database so field type cannot be changed to XML)The text field in the database is similar to the one below but I have simplified it by remove many of the unneeded tags in the <before> and <after> blocks. I also reformatted it to show the structure (original had no spaces or returns)
For each text field in the SQL table contain the XML I need to know the OldVal and the NewVal.
<ProductMergeAudit> <before> <table name="table1" description="Test Desc"> <product id="OldVal"> </table> </before> <after> <table name="table1" description="Test Desc"> <product id="NewVal"> </table> </after></ProductMergeAudit>

Hi,
I am very new to using SQL. Our department usually uses Brio to query the various databases under our control. However, I have recently come against a problem that prompted me to create a custom SQL query which works well as far as it goes. My problem is looking for specific conditions in billing information I receive monthly. I would like to compare on of the date fields contained in the database with a field in the form of YYYYMM (200710, for October 2007) I have created a custom column generator that forms a date from the YYYYMM. I would like, however, do the translation on the fly and make the comparison during the query. The problem is that query without the date check returns a mass of data, only about 1 percent of which is what I want.
The beginning of the SQL query looks like this:
FROM From.T_Crs_Tran_Dtl WHERE T_Crs_Tran_Dtl.Crs_Bill_Yr_Mo IN ('200710', '200711', '200712') AND ((T_Crs_Tran_Dtl.Crs_Cde IN ('1G', '1V') AND (T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND (T_Crs_Tran_Dtl.Prev_Stats_Cde IN (' ', 'TK', 'TL') AND T_Crs_Tran_Dtl.Cur_Stats_Cde IN ('TK', 'TL') AND T_Crs_Tran_Dtl.Std_Tran_Typ_Cde='B') OR (T_Crs_Tran_Dtl.Prev_Stats_Cde='UN' AND T_Crs_Tran_Dtl.Cur_Stats_Cde='XX' AND€¦
It is the €ś(T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND€? part of the query that is just plain wrong. The business part of this statement takes the YYYYMM field and turns it into a date which is the last day of YYYYMM.
I hope someone out there can help me with making this comparison.
I appreciate your help.
Bill

Hi everyone,
I'm extremely new to SQL so be nice
I am attempting to write a script to add onto the end of a text field the words " -- Disposed " (About 60 rows worth).
The field is a TEXT field, so unlike a varchar field I can't just use Update as shown below.
Code:
Update AR_Primary_asset
Set AR_Primary_asset.description = AR_Primary_asset.description + ' -- Disposed'
Where AR_Primary_Asset.ASSET_REF in ('1','2','4')
I found on the Mircosoft pages about UPDATETEXT, but this only seem to work to update one row (In the case below Asset_ref = 3, was the only row effected) .
Code:
DECLARE @Dispose binary(16)
SELECT @Dispose = TEXTPTR(DESCRIPTION)
FROM AR_PRIMARY_ASSET
WHERE AR_Primary_Asset.ASSET_REF in ('1','2','3')
UPDATETEXT AR_PRIMARY_ASSET.DESCRIPTION @ptrval null null ' -- Disposed'
So i wrapped it into a cursor, this worked on my test SQL server which runs SQL2005.
Code:
DECLARE @Dispose varbinary(16)
DECLARE cursor1 CURSOR FOR
SELECT TEXTPTR(DESCRIPTION)
FROM AR_Primary_Asset
Where AR_Primary_Asset.ASSET_REF in('1','2','3')
OPEN cursor1
FETCH NEXT FROM cursor1
INTO @Dispose
WHILE @@FETCH_STATUS = 0
BEGIN
UPDATETEXT AR_Primary_Asset.DESCRIPTION @Dispose NULL NULL ' -- Disposed'
FETCH NEXT FROM cursor1
INTO @Dispose
END
CLOSE cursor1
DEALLOCATE cursor1
But when it was run on our SQL2000 server it gave the following error message
Quote: Msg 403, Level 16, State 1, Line 1
Invalid operator for data type. Operator equals add, type equals text.
I've never used vars, cursors, updatetext or even text fields before. So maybe I am going about it totally the wrong way.
Is anyone able to tell me a better way to write this? or how to make it compatible to SQL2000?

Application is ocr'ing tiff image files and then storing the resultant text data in a text field in SQL 2005 database. This field is then used with the full text catalog.
All works fine,
However, am I using the correct field type to store the text files for efficiency and space saving?
If I use a binary field, does this reduce the size of the database by compressing the text data in the binary field? Also, is there a limit as to the size of text file that I could store in a binary field?
It would be good to get feedback on this before I go too far down the wrong road.
So, text field to store the text data or binary field to store the actual text file?

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,
Barkingdog

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,

P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick

New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?
