Re: Query with accents

Thanks for helping.

Windows is a mess, cp450 on terminal, win1252(ansi) on UI and need to be careful with editors, Delphi save our code (and strings) as Ansi, Lazarus save as unicode, so... Windows is not for amateurs.

Re: [zeos8] Wrong statement does noy triiger an exception when prepare, Why?

firedac can use both parameters and macros, they are very similar. But, macros can be used anywhere, including replacing verbs and keywords. It would be a great idea to have something similar on Zeos. Parameters on the other hand can only be used in values. FirebirdSQL will compile and cache them fo...

Re: [zeos8] Wrong statement does noy triiger an exception when prepare, Why?

Prepare queries need to submit sql code to a server previously and returning true of false from server to proceed. Some times, we do manually: if not query1.prepared then query1.prepare; Because another instante in same workstation or different point of network already prepared. Since BDE, IBX, IBO,...

Re: MSSQL 6.5(too old) is it possible to connect?

Yes, all of them refuse to connect using Win10, maybe is different using old windows versions. Just BDE may something different using Win10, because connect without any error.

Re: MSSQL 6.5(too old) is it possible to connect?

This version MSSQL Enterprise Manager does not generate SQL Script for data, only meta. But there is a transfer data utility to another MSSQL. I will try if MSSQL 2019 can import it from this transfer or from backup/restore.
