问题 I have a Firebird database (v. 2.5), I'm not allowed to create procedures, views or tables into the database, because of losing support. My view is too long: Too many Contexts of Relation/Procedure/Views. Maximum allowed is 255 I think I can solve this Problem by creating GTT, right? My question is, this GTT will be stored in the Database? When is the GTT deleted? I tried in a copy of my database and created a GTT, after that I closed my connection and reconnected and the GTT was there

问题 I have three tables: Table1 as master, Table2 as detail for table1 and Table3 as detail for Table2. TABLE1 PK1 INTEGER, FD1 VARCHAR(100) TABLE2 PK2 INTEGER, FK1 INTEGER, FD2 VARCHAR(100) TABLE3 PK3 INTEGER, FK2 INTEGER, FD3 VARCHAR(100) PK1, PK2, PK3 is auto incremented primary keys for table1, table2 and table3 respectively, while FK1 is a foreign key to PK1 and FK2 is a foreign key to PK2. I need to copy one record from Table1 to the same table with all its detail records from Table2 and

问题 I recently changed from AnyDac to FireDac (8.0.5.3365). We're running Delphi 2006. When I was using the AnyDac version of this component I could create a new database by doing the following.. Setup my connection fConnection.LoginPrompt := false; fConnection.ResourceOptions.SilentMode := true; fConnection.Params.Clear; fConnection.Params.Add(Format('DriverID=%s', ['IB'])); fConnection.Params.Add(Format('Database=%s', [fConnectionInfo.xDatabase])); fConnection.Params.Add(Format('CharacterSet=%s

问题 I have a production database, using Firebird 2.1, where I need to find out how much space is used by each table, including the blobs. The blob-part is the tricky one, because it is not covered using the standard statistical report. I do not have easy access to the server's desktop, so installing UDFs etc. is not a good solution. How can I do this easily? 回答1: You can count total size of all BLOB fields in a database with following statement: EXECUTE BLOCK RETURNS (BLOB_SIZE BIGINT) AS DECLARE

问题 We're using NHibernate to great success with a Firebird backend. My question relates to the features available in NHibernate being supported by Firebird. If you have any expertise with Firebird and NHibernate your comments are welcome. Does Firebird support "Future" queries? From my reading it would appear that Firebird is one of a few databases that doesn't support this feature. Does anyone have a workaround as "Future" would be a good feature to utilise. Does Firebird support the NHibernate

问题 RedGate makes a tool for Microsoft SQL Server that allows you to snapshot the difference between two databases. It generates the scripts needed to update the database schema while preserving the data. I need to find a tool like this for the Firebird database. We use Firebird in an embedded fashion, and would like to push out schema updates to remote machines with as little hassle as possible. 回答1: I don't know of a tool for Firebird that does exactly the same. However, FlameRobin allows you
