xbrowse(autosort) + tdolphin - erro

[MGA]

I have an object 'xbrowse', using tdolphin. The main query has a relationship between tables, which coincidentally has a field in the table with the same name: "key". But this field is not part of the query.

SELECT p.key, p.data, c.name FROM orders AS p LEFT JOIN customers AS c ON(c.code=p.code)

the browse works fine, however when clicking on the header (autosort) of the "key" column, an error is generated.

Note: When clicking on the header of the 'key' column, internally xbrowse does:

SELECT * FROM orders AS p LEFT JOIN customers AS c ON(c.code=p.code) ORDER by key

I believe this is the problem. How can I solve the situation?

example:

estrutura:

table pedidos:
chave
data
codigo

table clientes:
codigo
nome
chave

oQry := oServer:Query('SELECT p.chave, p.data, c.nome FROM pedidos AS p LEFT JOIN clientes AS c ON(c.codigo=p.codigo)'

@ 0,0 XBROWSE oBrowse OF oDialog OBJECT oQry AUTOCOLS AUTOSORT LINES

with object oBrowse:oCol(1)
:cHeader := 'Chave'
:cEditPicture := '@!'
:bEditValue := {|| oQry:chave}
end

with object oBrowse:oCol(2)
:cHeader := 'Data'
:cEditPicture := '@!'
:bEditValue := {|| oQry:data}
end

cmsoft,

Friend, thanks for answering.

The problem happens when there is ORDER BY in the query. I redid it below in your code, and the error occurs. Without ORDER BY, there is no error.


#include "FiveWin.ch"
#include "xBrowse.ch"
#include "tdolphin.ch"
function Main()
LOCAL oForm, oServer, oQry, oBrw
CONNECT oServer HOST 'localhost' ;
USER 'root' ;
PASSWORD 'miclave' ;
PORT 3306 ;
FLAGS 0;
DATABASE 'test'
oQry := oServer:Query('SELECT p.chave as chave, p.data as data, c.nome as nome FROM ped AS p LEFT JOIN cli AS c ON(c.codigo=p.codigo) ORDER BY p.chave')
DEFINE DIALOG oForm TITLE "MGA" FROM 05,10 TO 42,100

@ 00,00 XBROWSE oBrw DATASOURCE oQry;
COLUMNS "chave","data","nome";
HEADERS "Chave","Data","Nome";
SIZES 100,300,100;
OF oForm SIZE 340,215 PIXEL AUTOSORT LINES

oBrw:CreateFromCode()

ACTIVATE DIALOG oForm CENTER
RETURN nil

Here the error occurs, it seems that internally xbrowse does SELECT *... see the error log

Here the error occurs, it seems that internally xbrowse does SELECT *... see the error log

There is NO problem with XBrowse.
XBroswe does not make any SELECT queries.
XBrowse simply calls

Code: Select all  Expand view  RUN

oYourDolpinQry:SetOrder( cFieldName )

Your error is occurring inside Dolphin Qry's SetOrder method.
The problem must be with the names you used to prepare your query.
