Delphi - ZEOS MySQL - access denied -

-

i trying connect mysql database server (version 5.6) on web, delphi 7 application...

with mysql workbench, works ok, can run select queries test user (the same user not working in delphi 7)...

in delphi, using tzeosconn 7.1.4-stable , typed correct hostname db server, correct username , password... (parameter loginprompt = false) when change "connected" true, working ok...

but when trying execute simple query:

zq.sql.text:='select field database.table id='+inttostr(x)+';'; zq.execsql;

where zq tzquery, , x integer,

i got error: **ezsqlexception .. select command denied @my_internet_hostname **

when logged in mysql workbench, see same user wildcard session, mydbuser@% , same select works fine

so think, problem in zeos component, adding automatically internet provider hostname...

on mysql server have wildcard hostnames allowed ( - '%' - hosts can access mysql db )

can suggest me, problem zeos component???

ps: sorry english , formatting

does mysql server internet ?

  • first of : internet provider allows direct access mysql database pipe/socket connexion ? internet provider don't allow because of security matters. (they can open special ip/port if ask them).

  • second : did have grant option ? can cause problem zeos component.

    grant usage on . 'root'@'%'

    grant privileges on mydb.* 'root'@'%' grant option

if remember well, after change privilege works. local network mysql server (with easyphp , wamp tested).

i advise connect dsn string : check below way connect :

http://synopse.info/forum/viewtopic.php?id=1547

var   dsn : string; begin   dsn := 'zdbc:mysql://192.168.2.60:3306/world?username=root;password=dev';

u can use zeosconnexion initialize, , careful charset used : iso-8859-1, iso-8859-15, utf-8, ansi. because delphi 7 using ansi, , internet servers use others utf-8.

anyway see error in code : 

zq.sql.text:='select field database.table id='+inttostr(x)+';'; zq.execsql;

execsql used update, insert, delete commands, select command return records it's more convenient use open command :

zq.close; zq.sql.text:='select field database.table id='+inttostr(x)+';'; zq.open;

i give many path investigate, hope helps.
