Hi,
I don't know if it's the right place to ask, maybe it's for the lazarus
list.
Anyway, I'm trying to make a console-application that writes data to a
Firebird database. With Lazarus I created a console application.
I seem to be able to connect and open the table, but I can't insert data.
Are there examples anywhere ? I know how to do this in a graphical
environment, but I need the console app, it will run on a non-gui server.
Here is my code that goes in the application on-create method :
MyDB:=TIBConnection.Create(nil);
MyDB.Hostname:='server';
MyDB.DatabaseName:='/data/firebird/database.fdb';
MyDB.Transaction:=DupFilesTransaction;
MyDB.UserName:='user';
MyDB.Password:='password';
try
MyDB.Open;
writeln('DB open');
except
on E: Exception do
begin
writeln(E.Message);
end;
end;
myTransaction:=TSQLTransaction.Create(nil);
myTransaction.Database:=MyDB;
try
myTransaction.StartTransaction;
writeln('Transaction open');
except
on E: Exception do
begin
writeln(E.Message);
end;
end;
myTable:=TSQLQuery.Create(nil);
myTable.Database:=MyDB;
myTable.Transaction:=myTransaction;
myTable.SQL.Clear;
myTable.SQL.Add('select * from myTable');
myTable.InsertSQL.Clear;
myTable.InsertSQL.Add('INSERT INTO myTable(');
myTable.InsertSQL.Add( 'Field1,');
myTable.InsertSQL.Add( 'Field2');
myTable.InsertSQL.Add( ')');
myTable.InsertSQL.Add( 'VALUES(');
myTable.InsertSQL.Add( ':Field1,');
myTable.InsertSQL.Add( ':Field2');
myTable.InsertSQL.Add( ')');
try
myTable.Open;
writeln('Table open');
except
on E: Exception do
begin
writeln(E.Message);
end;
end;
When I insert values I do :
myTable.Params.ParamByName('Field1').Value:='Value1';
myTable.Params.ParamByName('Field2').Value:='Value2';
try
myTable.ApplyUpdates;
except
on E: Exception do
writeln(E.Message)
end;
If I try this I get an error stating parameter Field1 does not exist.
Any references ?
Thanks,
Koenraad Lelong.
