You wan to load it from the disk file into memory (string var), and then store it to a BLOB field in SQL. You can optionally base64 encode it beforehand too.

**Scott Slater** · 16 Jul 2009, 08:50 PM

Code:

Open PDF_FILE$ for Binary as 1
Get$ 1, Lof(1), sBuff$
Close 1

SQL INSERT....

to read it back...

SQL SELECT to get raw data back into sBuff$

Open PDF_FILE$ for Binary as 1
Put$ 1, sBuff$
Close 1

ViewPDF PDF_FILE$

Kill PDF_FILE$

That's roughly the steps... give or take.

**BOB MECHLER** · 17 Jul 2009, 12:47 PM

Just needed someone to confirm the steps. Thanks,

Bob Mechler

**Carlo Pagani** · 17 Jul 2009, 02:57 PM

Bob, a BINARY field would be best. How you get it in depends on what you've got. If you have SQL tools I will post a routine for you. Also, for completeness, please state the version of MS SQL you are using.

**BOB MECHLER** · 17 Jul 2009, 03:05 PM

Thanks Carlo,

Using MS SQL 2005 Express for my testing. I have SQL TOOLS pro.
A co-worker suggested the 'image' field type.

Bob Mechler

**Carlo Pagani** · 17 Jul 2009, 03:26 PM

ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Binary is the right one to use. I'll cobble together some code for you in next few minutes....

Code:

'Basic structure to insert your PDF file into a binary field
local SQL, PDF_File as STRING
local lResult as long

SQL = "insert YourTable(SomeIntField, SomeTextField, YourPDFField) "+_
  "values("+Str$(SomeNumericVariable)+",'"+SomeTextVariable+"',?)" 'You will probably have more fields
lResult = SQL_Statement(1, 1, %SQL_STMT_PREPARE,SQL) '

IF lResult = %Success THEN
  'Bind parameters
  lResult = SQL_BindParameter(1, 1, 1, %SQL_PARAM_INPUT, 99, %SQL_VARBINARY, LEN(PDF_File), 0, 1, LEN(PDF_File), %SQL_LONG_DATA)             'lIndicator&

  IF lResult = %Success then
    'Execute the SQL statement
    lResult = SQL_Statement(1, 1, %SQL_STMT_EXECUTE, "")

    if lResult = %Success then
      'Tell the driver that we are about to "fill" a parameter
      lResult = SQL_NextParameter(1, 1)

      IF lResult = %Success then
        lResult = SQL_LongParameter(1, 1, PDF_File, LEN(PDF_File))
      
        if lResult = %Success then
           lResult = SQL_NextParameter(1, 1)
        end if
      end if
    end if
  end if
end if
if lResult <> %Success then
  'Something failed
  'Report error
end if

**BOB MECHLER** · 17 Jul 2009, 04:12 PM

Thanks, I think I can follow this well enough.

Bob Mechler

**BOB MECHLER** · 17 Jul 2009, 04:47 PM

Very helpful.

The following code adapted from your post seemed to insert the row and it reports <binary data> in the parameterized field PDFDOC but I get 2 function sequence errors at

SQL_MsgBox SQL_ErrorQuickOne + " 4", MSGBOX_OK
SQL_MsgBox SQL_ErrorQuickOne + " 5", MSGBOX_OK

I changed the field to varbinary(50) which I assume adjusts to the size needed, cause there was no choice for just Binary or VarBinary in 2005 Express.

Code:

      'Basic structure to insert your PDF file into a binary field
      local SQL AS STRING, PDF_File as STRING
      'local lResult as long

      OPEN "C:\PDFS\CULAND2.PDF" FOR BINARY AS 1
        GET$ 1,LOF(1),PDF_File 
      CLOSE 1
      SQL = "insert STMTPDFS ([ACCOUNT],[DATESTR],[QUALIFIER],[PDFDOC]) VALUES('1101500','2009-07-17','UNAUDITED',?)" 
      lresult& = SQL_Statement(1, 1, %SQL_STMT_PREPARE,SQL) '
      IF SQL_Errorpending THEN
        SQL_MsgBox SQL_ErrorQuickOne + " 1", MSGBOX_OK
      END IF
      
      IF lresult& = %Success THEN
        'Bind parameters
        lresult& = SQL_BindParameter(1, 1, 1, %SQL_PARAM_INPUT, 99, %SQL_VARBINARY, LEN(PDF_File), 0, 1, LEN(PDF_File), %SQL_LONG_DATA)             'lIndicator&
          IF SQL_Errorpending THEN
            SQL_MsgBox SQL_ErrorQuickOne + " 2", MSGBOX_OK
          END IF
      
        IF lresult& = %Success then
          'Execute the SQL statement
          lresult& = SQL_Statement(1, 1, %SQL_STMT_EXECUTE, "")
          IF SQL_Errorpending THEN
            SQL_MsgBox SQL_ErrorQuickOne + " 3", MSGBOX_OK
          END IF
      
          if lresult& = %Success then
            'Tell the driver that we are about to "fill" a parameter
            lresult& = SQL_NextParameter(1, 1)
            IF SQL_Errorpending THEN
              SQL_MsgBox SQL_ErrorQuickOne + " 4", MSGBOX_OK
            END IF
      
            IF lresult& = %Success then
              lresult& = SQL_LongParameter(1, 1, PDF_File, LEN(PDF_File))
              IF SQL_Errorpending THEN
                SQL_MsgBox SQL_ErrorQuickOne + " 5", MSGBOX_OK
              END IF
            
              if lresult& = %Success then
                 lresult& = SQL_NextParameter(1, 1)
                IF SQL_Errorpending THEN
                  SQL_MsgBox SQL_ErrorQuickOne + " 6", MSGBOX_OK
                END IF
              end if
            end if
          end if
        end if
      end if
      if lresult& <> %Success then
        msgbox "Problem somewhere"
      end if

**Michael Mattias** · 17 Jul 2009, 07:23 PM

Interesting... lots of SQL Tools' syntax, but no mention of SQL Tools.

Eric has GOT to be smiling about that.

**BOB MECHLER** · 17 Jul 2009, 10:57 PM

Pardon me, Michael. Review the start of post. Carlo asked if I had SQL Tools and I replied I had SQL Tools Pro.

No slight intended Eric. Fantastic product!

Bob Mechler

**Carlo Pagani** · 18 Jul 2009, 02:48 AM

Bob, BINARY was the wrong suggestion as it is a fixed length data type. I should have recommended VARBINARY(MAX) This will allow you to save anything up to 2GB in size.

From the SQL Book, "Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length"

SQL Tools has certainly made my life working with data a more pleasant experience.

**Michael Mattias** · 18 Jul 2009, 09:32 AM

Whoa, I went right past those references to SQL Tools. Never saw 'em; lucky I wasn't looking out for a bus so I could safely cross the street.

Eric has STILL got to be smiling, albeit for a different reason.

**BOB MECHLER** · 18 Jul 2009, 01:55 PM

The next step

The following code inserts a record and supposedly a PDF into an SQL 2005 table. The proof of course is if I can retrieve the PDF into a variable. Here is where I've gotten to so far but the results show 0 bytes read.

All the other fields are retrieved as you would expect.

Maybe I should put this on the Third party forum.

Code:

      'Basic structure to insert your PDF file into a binary field
      local SQL AS STRING, PDF_File as STRING
      'local lResult as long
      SHELL ENVIRON$("COMSPEC") + " /C C:\PDFS\CULAND2.PDF",0
      OPEN "C:\PDFS\CULAND2.PDF" FOR BINARY AS 1
        GET$ 1,LOF(1),PDF_File 
      CLOSE 1
      SQL = "insert STMTPDFS ([ACCOUNT],[DATESTR],[QUALIFIER],[PDFDOC]) VALUES('1101500','2009-07-17','UNAUDITED',?)" 
      lresult& = SQL_Statement(1, 1, %SQL_STMT_PREPARE,SQL) '
      IF SQL_Errorpending THEN
        SQL_MsgBox SQL_ErrorQuickOne + " 1", MSGBOX_OK
      END IF
      
      IF lresult& = %Success THEN
        'Bind parameters
        lresult& = SQL_BindParameter(1, 1, 1, %SQL_PARAM_INPUT, 99, %SQL_LONGVARBINARY, LEN(PDF_File), 0, 1, LEN(PDF_File), %SQL_LONG_DATA)             'lIndicator&
          IF SQL_Errorpending THEN
            SQL_MsgBox SQL_ErrorQuickOne + " 2", MSGBOX_OK
          END IF
      
        IF lresult& = %Success then
          'Execute the SQL statement
          lresult& = SQL_Statement(1, 1, %SQL_STMT_EXECUTE, "")
          IF SQL_Errorpending THEN
            SQL_MsgBox SQL_ErrorQuickOne + " 3", MSGBOX_OK

          if lresult& = %Success then

**BOB MECHLER** · 18 Jul 2009, 05:31 PM

varbinary(max) produces a message indicating it must be between 1 to 8000. Must be because it's SQL 2005 EXPRESS.

It also may be an old sql 2000 db that I registered on the SQL 2005 EXPRESS management studio. I'll look at that for a while.

Bob Mechler

**Carlo Pagani** · 19 Jul 2009, 03:32 AM

Change the DB compatability to 9. If you are using a SQL 2000 DB then it would be limited to 8000 as SQL 2000 did not support VARCHAR(Max)

**BOB MECHLER** · 21 Jul 2009, 03:50 PM

Ended up using Jose Roca's fine ADO library and have a working program.

Bob Mechler

**Carlo Pagani** · 21 Jul 2009, 04:12 PM

Bob, it's not a SQL Tools issue. I tested with my wrappers and it works. Unfortunately I've written wrappers to suite my SQL tools needs and I use both varbinary and binary fields in SQL 2005 quite happily.... and very fast!

**BOB MECHLER** · 21 Jul 2009, 05:34 PM

I'm sure it's not an SQL Tools issue. It's a me issue. I've asked Eric to look at the code I've posted and see if he can determine what I'm doing wrong or tweak the code where needed.

I just got the ADO libs from Jose to work first, is all.

99% of my SQL work will still be with SQL Tools because for my stuff it's much faster than ADO for transaction processing etc.

Bob Mechler

**Michael Mattias** · 21 Jul 2009, 06:49 PM

99% of my SQL work will still be [Thru ODBC using ] SQL Tools because for my stuff it's much faster than ADO for transaction processing etc.

Just keep telling yourself that. You'll feel much better.

I just keep telling myself using OLE thru ADO is faster and it makes me feel much better.
