问题 I'm running Win7 64-bit and Firebird 2.5.2. Is it possible to access a 32-bit Firebird database via ODBC from a 64-bit C++ application? My initial thought was that I could just install the 64-bit Firebird ODBC driver and it would work. Sure enough, after installing it the 64-bit ODBC control panel app shows the Firebird driver, but the connection fails when trying to point it to an .fdb file created with 32-bit Firebird. I'm picking the client library from the 64-bit firebird install as well

问题 I'm running a software called Fishbowl inventory and it is running on a firebird database (Windows server 2003) at this time the fishbowl software is running extremely slow when more then one user accesses the software. I'm thinking I maybe able to speed up the application by forcing the database to run "In Memory". However I can not find documentation on how to do this. Any help would be greatly appreciated. Thank you in advance. Robert 回答1: Firebird does not have memory tables - they may or

问题 I have a table in Firebird with a PK column CREATE TABLE TEST ( ID CHAR(16) CHARACTER SET OCTETS NOT NULL, CONSTRAINT PK_TEST PRIMARY KEY (ID) ); OCTETS encoding are treated as bytes. I create a converter public class UUIDConverter implements Converter<byte[], UUID>{ @Override public Class<byte[]> fromType() { return byte[].class; } @Override public Class<UUID> toType() { return UUID.class; } @Override public UUID from(byte[] bytes) { if (bytes == null) return null; ByteBuffer bb = ByteBuffer

问题 I encountered a similar problem as dicussed in here: Firebird embedded installation issue: library could not be determined I'm running a python(3.5.2) script via ubuntu (16.04.4 LTS) which is connected to a firebird database.

问题 I'm strugling with error message "Incorrect values within SQLDA structure" when I'm trying to update blob field within Firebird 2.1 database from Delphi 2009 DBX application.

问题 I have a query that worked in our Firebird SQL data module. We migrated to MySQL and all my queries work no problem except for this one. Please help me fix this. I get an error: Failed to Execute. Unknown column 'part.id' in 'on clause' My Firebird query: SELECT vendor.name AS "Vendor Name", Cast(Cast(vendorparts.lastdate AS date) AS CHAR(10)) AS "Last Date", CASE product.price WHEN '0' THEN 'CONFIRM' WHEN NULL THEN 'CONFIRM' ELSE Round(product.price, 2) end AS "D-Price", Cast(vendorparts

问题 I got myself into a place where I need to port some functionality from a legacy Firebird database into MSSQL. The table schema and data was ok, all was enumerable and selectable for sysdba, however, the application layer is proving to be a pain. The database has some 1000+ procedures and I would like to to move them over with some review rather than rebuilding the whole DAL. The problem is (you guessed) that they all appear to be encrypted somehow. When I ask to alter it to generate a script

问题 I'm using a Firebird database and am trying the following sql but each time it returns 0, instead of 0.61538 (etc). SELECT (COUNT(myfield)/26) totalcount FROM mytable Now when I remove the /26, the totalcount returns 16 as it should. But when I add the divided by 26 back in, the result shows as 0, but it should show as the full decimal value of 0.615384... Does anyone know why it's not returning the full value? I've even tried wrapping it in a CAST((count(myfield)/26) as double) totalcount
