问题 i'm writing a VBA macro for Excel 2003. I'm importing various data from a sql database to the Excel sheets. I tried two ways to do that: QueryTables.Add(...) with ADO I was in favour of ADO, because it seemed to be the 'better' or 'cleaner" solution. Everything worked well until i tried to get a numeric value with ADO out of the database. Instead of returning the value 1842,47078 it returned 0,01842 . (just to show what i mean) Strange thing is: when i try it with QueryTables.Add(...) i get

问题 I have a Firebird query which I should rewrite into PostgreSQL code. SELECT TRIM(RL.RDB$RELATION_NAME), TRIM(FR.RDB$FIELD_NAME), FS.RDB$FIELD_TYPE FROM RDB$RELATIONS RL LEFT OUTER JOIN RDB$RELATION_FIELDS FR ON FR.RDB$RELATION_NAME = RL.RDB$RELATION_NAME LEFT OUTER JOIN RDB$FIELDS FS ON FS.RDB$FIELD_NAME = FR.RDB$FIELD_SOURCE WHERE (RL.RDB$VIEW_BLR IS NULL) ORDER BY RL.RDB$RELATION_NAME, FR.RDB$FIELD_NAME I understand SQL, but have no idea, how to work with this system tables like RDB

问题 I'm trying to work around the problem with connection string encoding in Firebird .net provider ver >= 5.6.0.0 (current is 5.8.0.0). The full description of the problem (if you are interested in) is here, but I think I could explain it briefly. So let's start!

问题 I have RTF strings stored in a blob field in my database table. Example 1: The following blob RTF string stores plain text - 'Gluten, oeufs, lait, fruits à coque': {\rtf1\ansi\ansicpg1252\deff0{\fonttbl{\f0\fnil\fcharset0 Tahoma;}{\f1\fnil Tahoma;}}{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\lang4108\f0\fs16 Gluten, oeufs, lait, fruits \'e0 coque\f1\par} Example 2: {\rtf1\ansi\ansicpg1252\deff0\deflang4108{\fonttbl{\ \fnil\fcharset0 Tahoma;}{\f1\fnil Tahoma;}}{\*\generator

问题 I want to delete duplicated rows, so I used this select statement to find all duplicated rows. SELECT * FROM MY_CARD T1 INNER JOIN( SELECT IDCARD, YEAR FROM MYCARD GROUP BY IDCARD, YEAR HAVING COUNT(IDCARD) > 1 ) T2 ON T1.IDCARD = T2.IDCARD AND T1.YEAR=T2.YEAR WHERE T1.IDRODZ = 5 AND IDCARD=80; My result looks like that, but this is only short example, there are more duplicated records. ID IDCARD YEAR IDRODZ 1 80 2014 5 2 80 2014 5 3 80 2014 5 4 80 2015 5 5 80 2015 5 6 80 2015 5 I need delete

问题 I've got two computers both running Firebird (let's called them A and B) and two database files (let's call them a.fdb and b.fdb), both copied to both computers. On B I get the message b.fdb is not a valid database The other files work, on A both files work. This would be easy to explain, if B was an older version, but it's a newer one (it was FB 2.1, and because of this problem I installed FB 2.5). The files a.fdb and b.fdb have ODS 11.1 and 10.1, respectively. It looks like new versions of

问题 PostgreSQL has a CLUSTER command that can defrag the data on-demand rather than automatically which kills write speed. Can Firebird CLUSTER on demand? (I can't find it in the docs, and google searches come up well short. Pretty cars tho) 回答1: There is no such command for Firebird (which is also the reason you can't find it). Firebird doesn't have clustered indexes, and doesn't have a way to 'fake' them like PostgreSQL does. 来源： https://stackoverflow.com/questions/19389228/cluster-command-for

问题 Are there any conflicts if both Interbase and Firebird are installed on the same workstation? Does anyone have any tips or best practices for this? 回答1: Interbase uses port 3050 by default. So, you have to choose another number for Firebird server on the same machine. Port number is specified through firebird.conf file. You have to restart Firebird service after changing conf file. Actually I have four different versions of FB running on my development computer. In this case every instance
