Thread: PostGreSql equivalents to mssql
Hi,
i am a novice at PostGreSQL
but have some idea of MsSqlServer
Migrating to PostGreSql, i need to know how capable pgsql Functions are , Vis a Vis SQLServer.
can pgsql functions replace all functionality provided by Stored Procedures of MSSqlServer
specifically:
1. do pgsql Functions
a.> return datasets
b.> return output parameters
2. does PostGreSQL have an equivalent to Triggers of SQLServer
i'd also appreciate any links to find out about
the possibility of exporting
data
relations
stored procs / functions / Triggers
from PostGreSQL database.
Thanks In Advance
regards

You cannot have [out] parameters in term of MS TSQL word, but your function could return a complex type, that will do a trick. Still you cannot return a recordset and [out] params, but do you need it?

Unfortunately I cannot tell you much about Postgres on Unix and client
on Windows, but all my test apps written on VB and PG running on Linux,
so this combination works and I think should not be much pain for you as
well.
Would be interesting to here real success story of happy marriage of
postgres and ADO.

thanks for the caution Maksim ,
but i do need to have my database on PostGreSql running on a
unix/linux
box.
and i just need to have the application on Windows + .Net
i can use odbc.net or inherit the adapter
do you still see any possibility of serious issues !?
please do let me know if i am headed in the wrong direction
regards

So I would tell you, before doing something ask yourself what is you
goal,
if you shop primary OS is MS Windows and client is
VB or .Net or more generally ADO 2.7.x you'll probably looking into
wrong direction,
because nothing works better with ADO then MS SQL Server.
I am not telling you that postgres will not suite you, that will if you
are
following certain pattern.
What is you goal?

thanks for the reply:
but Functions can do return Cursor !
can i parse them from a .Net application ?
also i've found that PostGreSql 7.3 + can return recordset
http://techdocs.postgresql.org/guides/SetReturningFunctions
please reply if i can parse , using a .Net application or any such fromt
end
application,
a.> cursors returned by a PostGreSql function
b.> recordset ( multiple rows and columns ) returned by a PostGreSql
function

You cannot have [out] parameters in term of MS TSQL word,

Daily snapshots can be downloaded from: http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/snapshots.html Also, if I read your email correctly, are you from India? We already have 21 languages in preparation. India, with 1,6 billion inhabitants by 2040, is one of our main targets. If you would like to translate pgAdmin3 into Indi, please refer to this documentation: http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_steps.html http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_guidelines.html http://cvs.pgadmin.org/cgi-bin/viewcvs.cgi/*checkout*/pgadmin3/docs/en_US/translation_team.html Best regards, Jean-Michel
