I need to convert a table from PostgreSQL to MySQL. The size of the table is 5.2GB. I am doing it on workbench, but after some 3minutes I am getting errors like below.

\n\n

HY001:14:Out of memory in allocating item buffer.

\n\n

I have tried changing innodb_log_file_size, innodb_log_buffer_size, query_cache_size, key_buffer_size and some other variables, but no go.

\n\n

Can someone help me in doing this. Is there is any other conversion tools to do this. It will be great if I solve the above error too.

I am trying to add a validation to prevent the user from entering a url that does not include the word 'mywebsite' in it.

\n\n
validates :url, inclusion: { in: %w(mywebsite), message: \"Must be a mywebsite.com subdomain\" }\n
\n\n

The problem with the above code is that it will only accept 'mywebsite' as a valid argument, while I'd like it to accept any argument which includes the word mywebsite in it. Example: mywebsite.com/something

\n\n

How should I approach this?

I've made a WebView where it checks internet connection and if there is none it will display an error-page.

\n\n

It worked just fine until it recently when it would just display the error-page even though me having cellular data on, this persists even on WiFi's.

Is it possible to transpose data for a select column in Crystal? Here is my issue... I am using ttx file to get data fields for the Crystal Report...

\n\n

I want only the tax_type and the tax_rate and tax amount to show up in the same row as the product sold. The tax_rate is stored in a separate table that needs to be pulled in as a column as well. I need to group and sum on product, buy, sell, tax_type, and then net the whole amount to come up with net total which I kinda know how... but I am stuck at transposing a row. Basically I only want to show row as column where tax type, amount, and rate matches transaction number and YN_tax == 1. The tax rate is stored in a totally separate table... Mind you that tax will not be applicable to each transaction... Here are the table Details

I have been testing my code for the past few hours and I am stumped. This program takes a text file of names, turns the names into a list, prints the names, sorts the names, prints the sorted names, then allows you to search through the list. Everything seems to be working fine, but the one issue I have is exiting the while loop. If y or Y is selected you can search again, but that also happens if anything else is selected. I added a print statement outside the loop so if anything other than y is selected then the program should end with that last printed string, but it doesn't seem to be working. Does anyone have any ideas about why it isn't working and what I could change to get it to work?

\n\n

Thank you for your time.
