I need to combine two tables with 1 to many relationship using union but to no success. I've been trying to use this code select a.equipmentid, a.codename, a.name, a.labelid, a.ACQUISITIONDATE, a.description from TBL_EQUIPMENTMST a where a.partofid = '57' union all select first 1 b.warrantyid, b.startdate, b.enddate from tbl_equipwarranty b inner join TBL_EQUIPMENTMST c on b.equipmentid=c.equipmentid where c.partofid = '57' and b.servicetype='service' order by b.warrantyid desc union all select first 1 d.warrantyid, d.startdate, d.enddate from tbl_equipwarranty d inner join TBL_EQUIPMENTMST e

I'm using Firebird 2.1. There is a table name Folders , with the fields: FolderID ParentFolderID FolderName ParentFolderID is -1 if it's the root folder -- otherwise it contains the parent folder's ID. How can I find all parents (up to the root folder) of a low level node? Do I need a recursive query? ( Firebird supports them ) Something like this: WITH RECURSIVE hierarchy (folderid, ParentFolderId, FolderName) as ( SELECT folderid, ParentFolderId, FolderName FROM folders WHERE ParentFolderID = -1 UNION ALL SELECT folderid, ParentFolderId, FolderName FROM folders f JOIN hierarchy p ON p

I would like to union some data, but a simple select example not working. Selecting existing tables work fine... SELECT 1 as foo Message: can't format message 13:896 -- message file C:\xxxx\firebird.msg not found. Dynamic SQL Error. SQL error code = -104. corrupt pool. In MySQL and Postgres is no problem with these simple select.. Thanks for help! Firebird (like many other DBMS) requires a FROM clause. In Oracle you'd use the DUAL table, in Firebird you can use RDB$DATABASE SELECT 1 as foo FROM RDB$DATABASE; As RDB$DATABASE always contains exactly one row, this works the same way as Oracle's

I want to return the error message from a procedure when an exception happens. In SQL Server you would select the Error_Number() and Error_Message(). How would I do it in FirebirdSql SET TERM ^ ; CREATE PROCEDURE sprocname ( id int ) RETURNS ( gcode int, errmsg varchar(250) ) AS BEGIN gcode = 0; errmsg = ''; -- do procedure code here WHEN ANY DO BEGIN gcode = gdscode; -- ?? errmsg = ??; END SUSPEND; END^ SET TERM ; ^ Unfortunately you will need to do that at the client side, as it is currently not possible to obtain this in PSQL. There is a feature request in the Firebird tracker, which has

Say I have a table with the following data: Now I want to filter by the primary keys department and number. I have a list of department and number combinations that have to be filtered in code. In my mind, I would create a join that results in the following: select * from employee e inner join dynamicTable dyn on e.Department = dyn.Department and e.Number = dyn.Number; dynamicTable is my List in C# code that has the primary keys to filter, but I don't know how to pass this list to the database level. I dont't want to load everything from my employees table and that filter in code by linq or
