[GENERAL] Moving from SQL Anywhere to PostGres - First Time
Hello, We have 700 user install base using Sybase SQL Anywhere 9.02 We are looking at migrating these installations over to PostGres 1. Very Very Short Answer Please - why should we? 2. Does anyone have a utility or migration application to read SQL Anywhere to go to PostGres 3. Does PostGres handle column descriptions (ie: you can give each column a 50 character description) and then access it via SQL Result Set (like I can do in Sybase) 4. Is there any Date/TimeStamp issues and conversions I need to know about. I use simply a DATE field and a TIME field - but do not use DATE/TIME stamp fields together. 5. What UI/Developer tools (GUI) are available to manage the database as well as add/change columns rather than doing it via SQL commands. Thank you. -Robert -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
Re: [GENERAL] Moving from SQL Anywhere to PostGres - First Time
Hi, Price and features. There are some changes in V12 which is causing us to do some steps with our support and resellers. We've always wanted to move away from Sybase so we can make more of a profit off our software and lower costs for us and our clients. Sybase is a wonderful product, and when things stay the same - we stay the same. But, since V12 is requiring us to make internal changes, step changes, documentation changes, training changes ... then it's a good time for us to stop and look at alternatives if we were going to look at them anyway. If we can save $100K a year moving to PostGres and give our customers better pricing, then it only makes sense to move - if PostGres does the same thing that Sybase does. They are a premium software vendor and have a premium product, but charge a premium price for it. They've made huge changes that affect us, and won't make any exceptions or changes for us, so now is the time to start looking at our options. -Robert "Michael Gould" wrote in message news:393bf55cebd45c71fec623552acbd...@intermodalsoftwaresolutions.net... Robert, We used Data Manager from JP to do this. Worked well. He recently added the ability to read OEM versions of ASA. How's come your moving away from SQL Anywhere?

[GENERAL] Need help accessing TABLES, COLUMNS, DESCRIPTIONS
Hello, I can't figure this out, and need help. I need access (VIA SQL Statements) to retreive a list of all PUBLIC tables, columns and their descriptions. I found: tables columns pg_description 1. There is no link between the description (object ID and the tables/columns) 2. pg_descriptions seems to be in another place than tables/columns, why? (inaccessible) 3. I also need access to the user (table of users) and which tables they have access to. Meaning, an sql statement that says: Give me all the tables, columns and descriptions of all the PUBLIC tables a particular user has access to: For example: select table,table_object_id, column, column_object_Id, isColumnPrimaryKey,Column_Description from tables,columns,pg_descriptions join (tell me) where they are 'public' tables and are accessible by user 'ReportUser' I can do this in Sybase SQL Anywhere very easily. I need to do it in PostGreSQL 9 Thank you. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I hear there are several, But I can't understand why someone would want to perform non-graphical tasks using a GUI. Because it is easier. I've managed to do everything I need - as well as write a full query editor/report writer for PostGreSQL. It is being beta tested now, and I plan on releasing it within the next 2 or 3 weeks. It adds about 8 extensions to the PostGreSQL language - and does many things. You'll see why it is nice to use a nice/pleasant GUI interface. ie: /* Check to make sure all email addresses have valid domain names */ select lastname,firstname,email from profiles domain check on email OR /* return a list, subtotalling adults and child by state */ select state,lastname,firstname,email,adults,child from profile order by state subtotal adults,child on state OR /* highlight all credits in red */ select company,balance from accounts highlight balance where balance < 0 bgcolor=COLOR:RED -Robert "Jasen Betts" wrote in message news:ihmf86$98d$1...@reversiblemaps.ath.cx...

Very Very Short Answer Please - why should we? postgres is the best database in the universe. :) 2. Does anyone have a utility or migration application to read SQL Anywhere to go to PostGres sed ? Any stock utility is likely to make choices that are sub optimal for your needs. with 700 changeovers pending I would want complete control over how each column is handled. 3. Does PostGres handle column descriptions (ie: you can give each column a 50 character description) and then access it via SQL Result Set (like I can do in Sybase) you can put descriptions on columns, I have not hit a length limit. (probably several megabytes like other text fields). Getting descriptions in the same same result set as column data is probably impractical (see length limit for a possible reason why this has not been implemented). fetching them separately en-masse and caching them or fetching or individually afterwards should not be greatly difficult, resultsets are returned with the column and table indicated. 4. Is there any Date/TimeStamp issues and conversions I need to know about. I use simply a DATE field and a TIME field - but do not use DATE/TIME stamp fields together. time goes upto 24:00:00.99 just incase you come across a day that long. so unless that's going to cause problems there should be no issues. the range supported by date is starts in pre-history and continues for a few million years into the future. 5.
