Wow.  I am impressed it performed that well.

Yes.   Depending on many factors the cell limit for an Array in WinBatch is around 10mil but you have a lot of wide columns so 8 mil is not unexpected.

Glad to hear my Extender wasn't a limiting factor.  I am very pleased.  Performance was pretty reasonable as well I thought, at least up to 250,000.  80 seconds seemed a bit long but probably nothing I can do about that. 

Thanks for the info.

Jim


Jim,

Here are some stats on dbGetRows() on my system, a i7 notebook with 16GB Ram, 1 TB Intel SSD (Split C/D and both partitions are really full, my bad, and the system is anything but dry... many programs and a boat load of background stuff = busy system, but that is how I run so I wanted to test i a realistic mode for me)

The Table I was running again is just over 3.5MM rows, 20 columns, average row width is just shy of 400 characters...  I was using a LIMIT on the SELECT to see what happened.... see code...

ROWS  TIME/SECs
100         0
500         0
1000       0
1500       0
2500       0
5000       0
10000     1
25000     0
50000     2
100000   3
250000   9
500000   ?  the process stopped at 415,832 lines (line incomplete) array.txt file size 59,848,153 bytes
415000   80  process complete initially 415,002 lines (completed) array.txt file size 59,728,611 bytes.

Then I got the following error trying to display the ARRAY
3096 Memory Allocation Failure, Out Of memory for strings.

Using: WinBatch 32 2020A
WIL Version 6.20ata


so I am guessing that is the max my system can chew at a time.

Code: [Select]
i = 500000
SQLText = "SELECT * FROM summ_by_Customer LIMIT %i%;"

ScriptStart = TimeYmdHms()
stmta = dbGetRows(db,SQLText,@TRUE,i + 3)
ScriptEnd = TimeYmdHms()

ArrayFilePutCsv("array.txt", stmta)  ; stmta not an Array?  Out-of-range error
Elapsed = TimeDiffSecs(ScriptEnd,ScriptStart)
Message("dbGetRows()","Processing Complete !!" : @CRLF : "Executed in: %Elapsed% Seconds" )

Jim,

Keep in mind that the file I/O of creating Array.txt is in that time, I do believe and my full filesystem will be impacting that time as well.
I watched  array.txt swell during those 80 seconds.

Jim,

I would guess that v4 may well become a workable piece of software.  I am in the process of automating my project.  It was in a different (DBased RAD Tool and I wanted to migrate it to SQL based tool) and I have all of the support scripts saved as separate .sql files for the entire process.  The goal was to move the project to a SQL based environment and then automate all but two or three steps that could not and make it easier to manage on a monthly basis.  I think dbSQLite is almost ready to take on the challenge and I certainly appreciate your attention to getting this put together as I think it will make my life a bit easier going forward.

Regards,
Keith

Jim;


I modified my original script to create an SQLite db and Table populated from a tab-delimited CSV file. The attached wakecounty.csv is tab=delimited and I included a 1-liner schema.ini (I'm working on a interface to autocreate the .ini) so Ace Provider wouldn't error. The process of inserting rows from the datatable into SQLite is a little slow and clumsy to look at. Since the database/sqlite table are identical in structure maybe there is a way to INSERT INTO....FROM - or some kind of bulk copy.  Anyway, be a nice project to replace the System.Data.SQLite with your extender. There was one bug. The original csv had a column Time Zone - which although could be created in the SQLite table, put out an error during the INSERT command. I changed it to TimeZone figuring there may be a need in SQLite to enclose multi-word columns in brackets

Nice work, as always.   Agreed on the clunky insert (speaking of SQLite insert, not your script).   They don't have a bulk option in SQLite, at least I don't think so, and one needs to use a transaction to make batches of INSERTs faster.   I am sure you and most others know this but for thoroughness...

BEGIN TRANSACTION;
INSERT....;
INSERT....;
COMMIT;

 I could create a batch insert but not sure how long it would take me to sort that one out :)    Will add it to my list.   Had thought about some "file" options, for OUT especially, since I am struggling getting the dbGetString() to allow for larger results.  Guess I could take the easy way out and have the batch be submitted as an Array.  Would avoid me having to parse delimited data.  Let WinBatch handle that load.  One extra step for the user and a whole lot of hours saved by me :)   The Batch Insert option would be fairly easy at that point (famous last words).

The next thing I want to get in place is UNICODE support.   Once that is done and everything is stable I will consider it ready for initial release and then continue adding new stuff.   While limited on some fronts, at that point it will allow one to do most anything they want with the database.    Need to test BLOBs I guess.   Haven't even checked on that yet.  Hopefully they work, as is.

I think I misunderstood what you were saying at first.    If I went with my idea of submitting an array for insert I think that would work well with what you are doing.   Do your query in the one and I think you can easily turn that into an array.  I assume RS.GetRows() works and submit that to my Extender.   Am I getting what you want?

Actually oTable.Select() returns an array. Could have come up with a full schema.ini with column types pre-defined then there would be no need to work with a .NET Datatable for column types. Basically use ACE Provider to query file as Recordset where GetRows() would work. I'm more interested in parsing delimited text on the fly and only stamping a schema.ini with a delimiter. I probably should have posted the script as a separate thread so as not to hi-jack the intent here. I was just pleased to get the syntax of the Create and Insert statements correct with minimal frustration. ;)

No problem.  Glad you got it sorted.   I could use some "minimal frustration" myself.   Plus such things generate ideas for improving what is being done here.

Not sure how much work it would be to parse delimited data in the Extender.   Mainly thinking about embedded quotes and such.  Now, if one had a file and then did dbInsertBatch(db,table,ArrayFileGetCSV(....)), if such a function existed, that would give me a cleanly separated source with which to work or, as noted, one can usually get an array of the results from the various recordset tools.   Really can't think of a situation where it would be a hassle to provide an array.

In any event, good work on what you posted and I am off to get this UNICODE thing sorted.

Here is the latest.   UNICODE is still whipping my butt so didn't want to hold up the dbInsertBatch() option and @dbVersion constant.

See notes in script on new function.  Nothing will run by default.  Also, if your source is UNICODE it will load correctly.   Now if only the output did the same.

Let me know how those 3.55 mil records do...hope they don't catch on fire from the blazing speed  ;)

Jim,

While I have not yet looked at v4 did you add a function that will take a flat file (no delimiters)?

If not, what about a function that will take column settings like 1-10, 11-10, etc however if you can do
that do not assume there isn't white space that is not needed like so many program do.  I would rather
specify every column start position and column length whether fields butt up to each other of not.

If that functionality isn't there my 3.5MM is not of value yet with your SQLite Extender.

Added a Help file to the v4 file just now.   Don't forget you will probably have to "Unblock" it under File Properties.

Also, if you have a suggestion for the SQLTemplate field indicators, let me know.  Don't really like all the braces but was having trouble thinking of something to use.

What about a Control string for SQLite   dbFlatFile (file_to_load_from,tablename,"FieldName!start-length,Field2!Start-length") with any undefined SQLite Fields set to NULL?  So you only specify what you are loading.

Probably good to change the Column Header option to a start row, as you suggest.   Give it a little more flexibiltiy.   Thinking of dbInsertBatch here.

Help me understand how the control string would be better than what I did?  Not disagreeing, just wanting to understand.  The current option allows you to specify which columns to load and there is a solid parser already in place or is this to allow for handling larger files which might not fit in an array?

What is "start-length"?

Jim,

IN  file_to_load  "start" is starting column and for "length" is to grab for the field.
The fieldname in the file_to_load does not need to be named as you are giving physical positions
FieldName regards to field in SQLite table to receive data

Internally you would need to dbSchema the table
Set what FieldName references you are given
Set unamed columns (in SQLIte) to NULL
and process file_to_load based on the above settings

Possible ???

It has been a long day and I will probably get it tomorrow but if you get a chance please mock up a function call for me using the Company table and load ID_NO, NAME and AGE.

Wouldn't you want to let SQLite handle the unaddressed fields with the Default values?   I can't imagine setting all to NULL as a default would be the desired behavior by all.   Will keep that in mind though.

I am off to bed.  Thanks again for all the help here.

Hopefully the attach file, data, example, etc will make things clearer for you.
If not, do not hesitate to ask for more clarification.  If you will add this it will
be a huge benny for me, as I come across this several times a year in the
work I do.

Okay.   Wondered if that was what you meant but was so tired my brain couldn't get any traction to follow through on the thought.

I have a plan.   We'll see where it goes.     Also going to tackle delimited files but only accept "clean" ones.   My brain almost explodes thinking about trying to parse something like:

1,""HELLO WORLD": A Programming Guide for C,C#,C++,etc.","Mr. Programmer,"aka Mr. P" Joseph"

Added dbInsertFlat().  I think you can do the "-" sign and NULL stuff via SQL without any problem.  See the examples in the test script and Help fil.

The configuration might seem a little hokey at first glance but I think it will work well and be easier to maintain.   Let me know if you disagree.

Jim,

Not sure what I am doing wrong here, I dropped the header line since it did not appear that the function would parse it correctly.
I had originally set to start with Line 2, but you were trying to parse line 1 anyway.  Deleting the Header was the simple fix for now.

The file (sample included) has 42 fields per row.  The first many rows have no values in he 1st two fields, but they start later in the file.
It is returning a "Syntax Error" on what I am guessing is the 10th field in the first row BUT since there are multiple values
(in this case a date in yyyymmdd format) I cannot be sure which field it really choked on.... nothing gets written to the SQL3
database.  Maybe you can either spot something I have wrong in the setup or get the Lib to give you a bit more information
about what it does not seem to like.

After a few hours of sleep, I will look at the flat, fixed record file... basically doing almost identical to this example...just different data.

Regards,
Keith

Not sure.  It is returning useful errors for me but not sure what it doesn't like yet.   It is failing on the 10th column no matter which row I start on.  I thought at first it was because you have 43 table columns but only 42 data columns.  Also thought it might be choking on the ID_NO because it is set to unique but most of the first column were the same.  I fixed those issues but get the exact same error.   Have to leave for a family thing so will be late today before I can get it sorted.  Sorry for the delay.

Jim,

Sorry about the 43 vs 42, was almost asleep and meant to chance the ID_NO to: ID_NO          INTEGER   PRIMARY KEY   AUTOINCREMENT
so that would be 43 fields  (ID plus my 42)  forgot to go back up and make that change.

I too have to run some errands today but have some other things to try when I get back.

You are missing a quote on every holder with the number 8 in it.  8, 18, 28, 38.

That was masking the other issues.

Is that what you would have expected for 42 loaded files with an AUTO_ID up front?

Yes.   The other option is to provide the column list before "Values" and leave out that column name.  But I am sure you know that.     Just to be clear there is nothing special I do here with the templates.  It is straight SQL.  You could do things like

       INSERT INTO BFS_Data Values (NULL, '[{0}]', '[{1}]', '[{2}]', Substr('[{3}]',1,6), '[{4}]', 'Peaches', '[{6}]'/'[{7}]', '[{8}]', CASE Substr('[{9}]',length('[{9}]'),1) WHEN '-' THEN '[{9}]'*-1 END;

Also, I have posted a new version which changes the place holders to

       [{n}]

I am going to stick with that unless someone tells me SOON that it isn't a good choice.  Seems a lot easier to read.

Jim

This is still v7 (I downloaded v8 but have not adjusted the {{{n}}} to [{n}] as of yet....
Thought you would like to have some real stats.....

CSV Load File is: 304,696KB containing 1,096,988 lines with the single header line.
the skip (starting line) DID NOT WORK, I ended up with the Header Line in my Database  !!
also  the dbSchema() function choKes on this file, process silently dies on BFS_Data table

Now here is the good news, I am using the following extender:
AddExtender("wilx44i.dll",0,"wilx64i.dll")               ; xGetElapsed

the xGetElapsed() & GetExactTime() timng functions

it loaded all (1,096,988 lns) on my full filesystem yielding a 197,460KB SQL3 DB in
1 min, 10secs & 54 hundereths

NOT BAD !!


this is the WB used for the testing....
Code: [Select]
AddExtender("wbsql44i.dll") ; SQLite3 Functions()
AddExtender("wilx44i.dll",0,"wilx64i.dll") ; xGetElapsed


db  = DirScript():"BFS_CSV_Test.sqlite"      ;INCLUDE FULL PATH FOR DATABASE

Jim,

dbTables() is starting to return garbage which is causing the process to silently die....
See screenshot.... DO NOT KNOW WHAT SUDDENLY CHANGED, been running the process over & over
to see what the variation in the load times I gave you.   Thy are within a second of each other until
this corruption. now the script will not even run thru. start when I tried the dbSchema() but that is
commented out and the database get deleted for each running....any ideas?

Keith

Please download v8 again and give that a try.   I thought I had removed all the HEAP stuff but those two were still using it.   Guessing it is related.   I was deleting it but maybe not correctly.
