Does SET_FIELD function exists in Oracle Form 10g or 12c? I hardly find documentation for this function.
Many Thanks
No it does not. I guess you are asking because it appears in a list of reserved words in the online help? That is because there was once a built-in procedure of that name in an earlier version. Use SET_ITEM_PROPERTY instead.
See http://www.oracle.com/technetwork/developer-tools/forms/264850-130496.pdf
To be precise, Tony's answer is not correct, in fact, in Oracle Forms 12c:
SET_FIELD procedure cannot be found in Oracle Forms help, it's exists only in "PL/SQL and Oracle Forms Reserved Words" list, so SET_FIELD could be tracted as deprecated;
At the same time SET_FIELD procedure still supported and works fine in Oracle Forms 12c (from working code). Oracle also mentioned SET_FIELD in Upgrading Oracle Forms 6i to Oracle Forms
12c:
Replace any references to obsolete logical
and GUI attributes in SET_ITEM_PROPERTY, SET_FIELD, or DISPLAY_ITEM with
an equivalent Visual Attribute.
P.S. Anyway, I personally going to replace all existing occurencies of SET_FIELD with SET_ITEM_PROPERTY :)

Our application successfully communicates with various databases (MSSQL, Oracle, Firebird) via ADO, that's why I'm trying to use ADO to add the PostgreSQL option to our software. I use standard PostgreSQL ODBC provider. All was fine until I faced with the problem with the large TEXT fields. When I use Unicode version of the provider and try to get TEXT field AsString, the application is just crushed with EAccessViolation in method RemoveMediumFreeBlock(). ANSI version works, but it cuts the content of the field (I guess the characters besides default 8190 LongVarChar limit). Small TEXT fields are read OK.
Could you suggest me what to do with this issue?
Is there the better option to work with PostgreSQL via ADO in Delphi?
Any idea how to go about doing that through a tool(preferred). Any alternate ways to do that.
You can check out the migration studio from EnterpriseDB here, although I have no experience with it.
There is no comparison to doing it yourself though - if you're not familiar with Postgres then this will get you familiar, and if you are, then aside from the data entry aspect, this should be old hat.
Use maxdb tools to generate a SQL text export of the database. Then import this file in PostgreSQL, luckily you won't need prior processing of the data dump.
I am new to db2. I have written procedures in oracle.
I need to convert those procedures from oracle to db2.
I want to know how the procedures in db2 will be created and compiled.
Thanks in advance.
A good walkthrough can be found here.
But then you always have the redbooks that IBM puts out such as this or this.
It is worth pointing out this migration tool that you might find useful.
I am trying to create a website using Symfony and PostgreSQL. I cant find any documentation that shows how to do this. All the documentation assumes the backend db is mySQL.
Anyone knows how to do this?
If you are using Doctrine, just use a dsn for pgSQL in your databases.yml, like this :
pgsql:dbname=testdb;host=127.0.0.1
It use the PDO syntax. Check the Doctrine documentation and PDO documentation.
Symfony uses 3rd-parties ORMs for DB communication which provide abstraction layer over RDBMS specific architecture. Basically everything you have to do is to change Doctrine's/Propel's driver name, so in /config/databaes.yml set pgsql instead of mysql and you're done.
The full answer (took me about an hour to figure this out) is:
Modify database.yml as described here (see under Propel or Doctrine)
(assuming you're using the Propel ORM like I am) Modify propel.ini as shown below (undocumented AFAIK)
Look for a section in your propel.ini names ;mysql options
comment the mysql options out - otherwise the generated SQL is a mix of postgresql and mysql - which confuses the hell out of psql.
I am looking for a tool/command which can compare data between two PostgreSQL databases. The reason to do this is to have some external verification that the SQL script responsible for data migration from one PostgreSQL database to the other have been written correctly.
Any pointers would be appreciated

EMS makes a tool which can do this.

The PostgreSQL site has a nice Software catalogue. Peruse the Administration/development tools category.
