[Lazarus] TPQConnection.CreateDB: ENCODING, OWNER, TEMPLATE, LC_CTYPE, TABLESPACE
Hello, I need to create a PostgreSQL database from my application. The TPQConnection.CreateDB works fine, but I need to configure some properties of my database in your creation. In pgAdmin, I execute: CREATE DATABASE myuser WITH ENCODING='UTF8' OWNER=myowner TEMPLATE=template1 LC_CTYPE='Portuguese_Brazil.1252' CONNECTION LIMIT=-1 TABLESPACE=pg_default; But, how to create a database with TPQConnection passing the ENCODING, OWNER, TEMPLATE, LC_CTYPE and TABLESPACE properties? Thank you! ps. I tried ExecuteDirect, but: "CREATE DATABASE cannot be executed inside a transaction block". -- Silvio Clécio My public projects - github.com/silvioprog -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Try setting them as 'Name=Value' pairs in the Params property of the connection component.

Hello buddy, sorry for my long delay. Thanks for the great tip, I tried it too, but unfortunately the postgre rejected that talking something like "unrecognized param for this operation". Today I fixed that using a "mix of codes": creating the database using the original postgre driver for Java, and calling "java -jar create_mydb " via TProcess. Now it worked like a charm!

Please don't raise a bug tracker issue... especially one with a simple sample program and PostgreSQL DDL so the issue is easily reproducible for devs. It's much better to keep using a workaround using another programming language and letting other programmers potentially face the same problem than getting it fixed in a newer version of FPC.

Damn, that looks difficult. You know that the bindings for the postgres driver are available for fpc? What you need is PQexec(Handle, 'create mydb And sqldb is not some magical tool, it's just a wrapper around this driver. You could have looked at TPQConnection.CreateDB and TPQConnection.ExecuteDirectPG. That way you could have added the parameters that you want. (If I look at ExecuteDirectPG, the parameters are only passed when a connection to the DB is made, not when it's created. It's trivial to add, though) Or you can just copy-paste the code and use a modified version of it in your application. Well, calling Java with a TProcess works also obviously...

Oopss... sorry, I'll do that dude. =)

Yes, but I needed to fix the problem urgently, and unfortunatelly with
SQLdb doesn't worked. =( The final (quick workaround) code was:
procedure TCriadorBanco.Criar(const ADatabase, AOwner, AUser, APassword,
ALocale, ATemplate: string);
var
VJavaExe: string;
VProcess: TProcess;
VResult: TStringList;
begin
VJavaExe :=
{$IFDEF MSWINDOWS}
IncludeTrailingPathDelimiter(GetEnvironmentVariable('JAVA_HOME'))
{$ELSE}
'/usr/'
{$ENDIF};
VJavaExe += 'bin' + DirectorySeparator + path.JAVA_EXE;
if not FileExists(VJavaExe) then
raise ECriadorBanco.CreateFmt(
'Executável do Java não encontrado: "%s".', [VJavaExe]);
if not FileExists(path.CREATE_DB_JAR) then
raise ECriadorBanco.CreateFmt(
'Arquivo JAR não encontrado: "%s".', [path.CREATE_DB_JAR]);
VProcess := TProcess.Create(nil);
VResult := TStringList.Create;
try
VProcess.Executable := path.JAVA_EXE;
VProcess.Options := VProcess.Options + [poWaitOnExit, poUsePipes,
poStderrToOutPut];
VProcess.Parameters.Add('-jar');
VProcess.Parameters.Add(path.CREATE_DB_JAR);
VProcess.Parameters.Add('-d=' + ADatabase);
VProcess.Parameters.Add('-o=' + AOwner);
VProcess.Parameters.Add('-u=' + AUser);
VProcess.Parameters.Add('-p=' + APassword);
VProcess.Parameters.Add('-l=' + ALocale);
VProcess.Parameters.Add('-t=' + ATemplate);
VProcess.Execute;
VResult.LoadFromStream(VProcess.Output);
if (VResult.Count = 2) and (VResult[0] = 'Role successfully created')
and
(VResult[1] = 'Database successfully created') then
else
raise ECriadorBanco.Create(Trim(VResult.Text));
finally
VResult.Free;
VProcess.Free;
end;
end;

Yes yes, I use that, and most of the time I send a diff to the bugtracker lol. ps. I'm so very glad for SQLdb allows me to create classes like "TConnection.GetInstance.Insert/Update/Delete" that returns the record ID instead of rowsaffected and a "TConnection.GetInstance.RawQuery/Query" that returns my own TCursor or a TArrayList instead of a tdataset. @.@ > Well, calling Java with a TProcess works also obviously... =) I love sqldb and fcl-*, but the problem needed to be solved urgently, forcing me to a workaround. =D -- Silvio Clécio My public projects - github.com/silvioprog -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
