I need to run queries over few txt tables. As I need to run queries in threads, I decided to change the sources with critical section. I know it can slow down things but at least it will work. I don't want xQuery to behave like Aloha protocol.<br /><br />odisejAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-38385155.post-74274094419014674242010-11-22T15:14:44.780+08:002010-11-22T15:14:44.780+08:00I understand TxQuery has stop it's development...I understand TxQuery has stop it's development, I was only hoping that someone who uses it would comment on issues I explained.Unknownhttps://www.blogger.com/profile/13812106071712395289noreply@blogger.comtag:blogger.com,1999:blog-38385155.post-73462826586857147422010-10-05T09:22:17.851+08:002010-10-05T09:22:17.851+08:00odisej, TxQuery has stop it's development.

Here are two major if anybody can comment.<br /><br />- We think xQuery is using some global variables so it's impossible to use it in threads.<br /><br />- xQuery knows UNIONs although we think you can't use sort on the whole UNION.Unknownhttps://www.blogger.com/profile/13812106071712395289noreply@blogger.comtag:blogger.com,1999:blog-38385155.post-29545567444150568592010-09-25T09:29:23.591+08:002010-09-25T09:29:23.591+08:00What issues you encounter when you trying to join ...What issues you encounter when you trying to join TDBF table?Chau Chee Yanghttps://www.blogger.com/profile/11816699461509455308noreply@blogger.comtag:blogger.com,1999:blog-38385155.post-68524393491231335862010-09-25T05:03:58.447+08:002010-09-25T05:03:58.447+08:00Hi, im using the TXQuery with TDBF in delphi 2010 ...Hi, im using the TXQuery with TDBF in delphi 2010 component but i have some issues with querys, trying join tables with 500 or more record, do you have any idea what can i do to fix this, and thanks for share this component..Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38385155.post-40467145895189233402010-09-23T08:46:14.654+08:002010-09-23T08:46:14.654+08:00I am not familiar with Halcyon database.

I also use the Halcyon database component to directly connect with dbase files rather than use the BDE. Versions of Halcyon of 6.94 or earlier work fine, but versions after 6.94 generate errors which appear to be a data conversion incompatibility with TxQuery. I don't know what changes were made to Halcyon to do this and am asking the Halcyon author what changes were made that might cause this incompatibility with TxQuery. If I knew, I would attempt to patch TxQuery myself but haven't got much time to investigate.<br /> <br />I don't believe this is a Unicode problem as it occurs with D5 and D7 which are not unicode enabled.<br />Do you know if anybody has run into the same problem?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38385155.post-88593320249834717192010-01-26T11:58:30.045+08:002010-01-26T11:58:30.045+08:00Thanks for sharing :-)Thanks for sharing :-)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-38385155.post-24258208493481998402009-12-10T10:18:37.119+08:002009-12-10T10:18:37.119+08:00Nice that the code was given to the community, and...Nice that the code was given to the community, and good to know that somebody takes care of it.Anonymousnoreply@blogger.com
