Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    lost in loop

    I have totally lost myself in a loop. Here is what I am trying to do:

    Open table
    set filter/order
    fetch first matching record
    open second table
    set filter/order
    fetch first matching record
    edit record in second table
    edit record in first table

    If I need to enter a new record in the second table, I have no problems. But since I need to find a matching record in the second table so that I can edit it, I am totally brain dead. The filter for the second table should be the matching inv_id fields.

    Here is my code when I want to enter a new record in the second table. Can somebody tell me where I need to make my modifications so that I can change the matching record in the second table?
    Code:
    dim t_source as P
dim t_dest as P
dim global vcgInv_ID as c

t_source = table.open("nceinvn")  'get here if valid serial number, so now we mark the records  
query.filter = "(serial_num = var->vcgSerialNum) .AND. (ship_num= \"\")"
query.options = "" 
qry = t_source.query_create() 
count = qry.records_get()

t_source.fetch_first()    'fetch first in filtered list
while .NOT. t_source.fetch_eof()
    t_dest = table.open("atvendor")    
    t_dest.enter_begin(.t.)
    t_dest.inv_id = t_source.Inv_id
    t_dest.atv_id = REMSPECIAL(API_UUIDCREATE())
    t_dest.vendor = vcgVendor
    t_dest.atv_shipno = vcgAtvShipNum
    t_dest.Rma = vcgRMA    '20060705 CKL added
    t_dest.Ven_out = date()
    t_dest.enter_end(.t.)
    
    xbasic_wait_for_idle()

    'Assign value to vcgInv_ID for use in filter when loading form
    vcgInv_ID = t_source.Inv_id
    
    xbasic_wait_for_idle()

    '20060702 CKL mark atven field to true
    t_source.change_begin(.t.)
    t_source.Atven = .t.
    t_source.change_end(.t.)
    
    xbasic_wait_for_idle()
    
   
    t_source.fetch_next()   'fetch the next record, should be none
end while   


t_source.query_detach_all()
t_source.close()
t_dest.close()

xbasic_wait_for_idle()

'=======================================================================
    The above code works great. Here is the garbage I have come up with to update a record in the second table, which is not even close to working. The filter is working on the first table, but the code never gets past that. I am not properly filtering/fetching the matching record in the second table, nor do I seem to be updating either record in the first or second table :(
    Code:
    dim t_source as P
dim t_dest as P
dim global vcgInv_ID as c

t_source = table.open("nceinvn")  'get here if valid serial number, so now we mark the records  
query.filter = "(serial_num = var->vcgSerialNum) .AND. (ship_num = \"\") .AND. (atven = .t.)"
query.options = "" 
qry = t_source.query_create() 
count = qry.records_get()

t_source.fetch_first()    'fetch first in filtered list
'Assign value to vcgInv_ID for use in filter when loading form
vcgInv_ID = t_source.Inv_id
while .NOT. t_source.fetch_eof()
    t_dest = table.open("atvendor")    
    query.filter = "(inv_id = var->vcgInv_ID)"
    query.options = "" 
    qry2 = t_dest.query_create() 
    count2 = qry2.records_get()
    t_dest.fetch_first()
    while .NOT. t_dest.fetch_eof()
        t_dest.change_begin(.t.)
         t_dest.Ven_in = vdgDateIn
           t_dest.change_end(.t.)
    t_dest.fetch_next()
    end while
    
        xbasic_wait_for_idle()

    'Assign value to vcgInv_ID for use in filter when loading form
    'vcgInv_ID = t_source.Inv_id
    
    'xbasic_wait_for_idle()

        '20060702 CKL mark atven field to false
        t_source.change_begin(.t.)
        t_source.Atven = .f.
        t_source.change_end(.t.)
    
        xbasic_wait_for_idle()
       
        t_source.fetch_next()   'fetch the next record, should be none
end while   

t_source.query_detach_all()
t_source.close()
t_dest.query_detach_all()
t_dest.close()

    Re: lost in loop

    Actually, the second table matching record is getting updated properly. The date in field is populated with the current date as expected, but that is where the script ends and gets lost.

    In actuallity, there is only one record in each table that will match the filters set.

      Re: lost in loop

      Are you sure the filter is working in the first instance? Seems

      Code:
      query.filter = "(serial_num = var->vcgSerialNum) .AND. (ship_num= \"\")"
      should be

      Code:
      query.filter = "(serial_num = "+quote(var->vcgSerialNum)+") .AND. (ship_num= \"\")"
      and

      Code:
      query.filter = "(serial_num = var->vcgSerialNum) .AND. (ship_num = \"\") .AND. (atven = .t.)"
      should be

      Code:
      query.filter = "(serial_num = "+quote(var->vcgSerialNum)+") .AND. (ship_num = \"\") .AND. (atven = .t.)"
      assuming var->vcgSerialNum is character.

      And
      Code:
      query.filter = "(inv_id = var->vcgInv_ID)"
      should be

      Code:
      query.filter = "(inv_id = "+quote(var->vcgInv_ID)+")"
      There can be only one.

        Re: lost in loop

        Yes the filters are working correctly when entering a new record in the second table and updating the existing record in the first table. I did, however, make the changes as you suggested since that is the proper syntax, and one day my filter probably will stop working.

        I don't think I will ever get my expressions right. You and Tom have given me so much help with expressions and I still can't seem to get them :(

        I do ok with my loops but only if they are simple loops. I always get lost when trying to do something different :(

        However, I did get it to work properly with the following:
        Code:
        dim t_source as P
dim t_dest as P
dim global vcgInv_ID as c

t_source = table.open("nceinvn")  'get here if valid serial number, so now we mark the records  
'query.filter = "(serial_num = var->vcgSerialNum) .AND. (ship_num = \"\") .AND. (atven = .t.)"
uery.filter = "(serial_num = "+quote(var->vcgSerialNum)+") .AND. (ship_num = \"\") .AND. (atven = .t.)"
query.options = "" 
qry = t_source.query_create() 
count = qry.records_get()

t_source.fetch_first()    'fetch first in filtered list
'Assign value to vcgInv_ID for use in filter when loading form
vcgInv_ID = t_source.Inv_id
while .NOT. t_source.fetch_eof()
    t_dest = table.open("atvendor")    
    query.filter = "inv_id = " + quote(var->vcgInv_ID)
    query.options = "" 
    qry2 = t_dest.query_create() 
    count2 = qry2.records_get()
    t_dest.fetch_first()
    while .NOT. t_dest.fetch_eof()
        t_dest.change_begin(.t.)
         t_dest.Ven_in = vdgDateIn
           t_dest.change_end(.t.)
    
        xbasic_wait_for_idle()

    'Assign value to vcgInv_ID for use in filter when loading form
    'vcgInv_ID = t_source.Inv_id
    
    'xbasic_wait_for_idle()

        '20060702 CKL mark atven field to false
        t_source.change_begin(.t.)
        t_source.Atven = .f.
        t_source.change_end(.t.)
    
        xbasic_wait_for_idle()
       
        t_source.fetch_next()   'fetch the next record, should be none
    t_dest.fetch_next()
    end while
end while   

t_source.query_detach_all()
t_source.close()
t_dest.query_detach_all()
t_dest.close()
        Edited: Now to go clean up my code tabs and commented out garbage so I can read it and understand it later :)
