error output to an Access DB - record is too large

DAM
7 - Meteor

Dear Community,

 

The output of an wf goes into an Access DB (I overwrite the table every time). I have tried with both mdb and accdb and I get the following error:

Error: Output Data (51): Error creating table Table1: Microsoft Access Database Engine: Record is too large.\3047 = -67175426CREATE TABLE "Table1" and all the fields are shown.

I have changed the Type and Size of the fields to String (less than 100) and Fixed Decimal, but no luck. What could be the issue?

I want to run the Workflow also on the Alteryx Server.

 

Thank you in advance for your help,

DAM

hi @DAM 

 

Depending on the structure of your data, you may be hitting this limit

 

Number of characters in a record (excluding Long Text and OLE Object fields) when the UnicodeCompression property of the fields is set to Yes

4,000

Hi danilang,

 

It seems that when I refershed the data, the Access DB exceeds 2 GB (although the data that I have it is not so big - aprox 1 mil records). The funny thing is that it worked before.

 

How can I overcome this? Also, I need an output file that works better, and in the same time to feed a pivot in excel.

 

Thanks

hi @DAM 

 

"the Access DB exceeds 2 GB"  Are you sure that you're updating existing records and not just continually inserting new ones?

 

"Also, I need an output file that works better, and in the same time to feed a pivot in excel."  You can send your data to excel as well as Access.  But if your process is writing more than 2 GB of data to Access, it's not going to work in excel either.

Hi Again,

 

In the Output Options I choose "Overwrite Table (Drop)". Excel it's not an option in this case.

If the size is bigger than 2GB don't bother using access, use an excel worksheet with linked table. This way you can keep more records without a problem.

I have tried to use excel but the number of records exceed 1 mil.

You are referring to have multiple worksheets and build a pivot from them based on unique field?

Yes that was my idea, but after it, trying to open the files is gonna put a lot of strain in the program and gonna be difficult to manage it.

 

Another solution would be to drop the table to an sql DB and use access as a front end, would also go faster.

 

There are some versions from the Microsoft sql server which are free (if you dont have one)

Can you please provide more details, how I should do it.

 

I am not sure if I am allowed to install it on my machine.I will give it a try.

Just install the software on your machine. On the output tool select then SQL server and configure the connection. If the connection was a success everything should go smoothly from there on.
