问题 I'm working on a poor, but ok for us , full-text search using only PSQL in Firebird. I'll try to simplify as much as possible by focusing on my problem: Summing up, this a dictionary table: SELECT * FROM FTS_KEYWORDS ID | KEYWORD ----+----------- 1 | 'FORD' 1 | 'MUSTANG' 1 | '2010' 2 | 'FORD' 2 | 'FUSION' 2 | 'TURBO' 2 | '2010' 3 | 'FORD' 3 | 'RANGER' 3 | 'TURBO' 3 | '2010' 3 | 'BLACK' There is too a FTS_TOKENIZE() procedure to get the words from the whole strings Case 1: User search with 1

Thanks in advance db.query('SELECT FIRST 10 * FROM client', function(err, result) { // IMPORTANT: close the connection console.log(result[0].name) db.detach(); }); 回答1: It is a Buffer object (NodeJS docu), which is the usual return value for data, whose type is not predetermined.

问题 My application has a design time TFDConnection and TFDPhysFBDriverLink as source connection. This may or may not be opened in Firebird embedded mode (if so, FDPhysFBDriverLink.VendorLib := 'fbembed.dll' is set (32 bits)). I create a run-time target TFDConnection which must use embedded Firebird because we do not know if Firebird is installed on the PC (our setup supplies fbembed.dll ). How do I set this up? At runtime I can create another TFDPhysFBDriverLink and set its VendorLib, but how

问题 I'm trying to enable migrations on a Firebird 2.5 database. I'm using VS2015 and the ADO Driver and Entity Provider are installed and working correctly.

问题 Having own generator in Firebird DB called GEN_PATIENT_ID I would like to leave the generation of ID on the DB side instead of NHibernate and FluentNHibernate. Following this link I am overriding the default Fluent behavior like this: public class PatientOverride : IAutoMappingOverride<Patient> { public void Override(AutoMapping<Patient> mapping) { mapping.Cache.ReadOnly().Region("LongTermReadWrite"); mapping.Id(x => x.Id).GeneratedBy.Sequence("GEN_PATIENT_ID"); mapping.HasOne(patient =>

问题 Following on from my question here How to REVOKE ROLE GRANTED BY another user on Firebird 2.5.8? and @Arioch's helpful suggestion to query what ROLE is actually connected prior to the command. SELECT CURRENT_ROLE FROM RDB$DATABASE Now despite my connection string explicitly using "ROLE=RDB$ADMIN", checking in gsec that the given user has admin option, when I run the command the result is NONE. This was using the Firebird ADO.NET FirebirdSql.Data.FirebirdClient interface v6.6. So I performed a

问题 Inserting null into not null column with default is giving me a validation error instead of taking the default value. I don't want to make on before triggers to all of the tables. Is there any other way to do this? Firebird 2.1.3 回答1: The default value is used when you omit a field in the insert, not when you include the field with a null value.
