The Delphi compiler throws a warning that the result of PingServer could be undefined. I modified the procedure to

The Delphi compiler throws a compiler hint for FillTableRefs beause CurrentType is never used in one case. So I modified the procedure to remove this hint procedure TZGenericStatementAnalyser.FillTableRefs( SelectSchema: IZSelectSchema; FromTokens: TStrings); var TokenIndex: Integer; Catalog: string...

The function GetBestRowIdentifier has to variables (IndexName and ColumnNames) which are declared but never used. So I commented them out to stop bloating the compiler log function TZAbstractDatabaseMetadata.GetBestRowIdentifier(const Catalog: string; const Schema: string; const Table: string; Scope...

Thanks

Currently the Delphi compiler throws a hint that the assigned return value for ExecuteDirect is never used. By modifying function TZConnection.ExecuteDirect(SQL:string; var RowsAffected:integer):boolean; var stmt : IZStatement; begin result := False; CheckConnected; stmt := DbcConnection.CreateState...

mdaems: Just take a look at my modified unit.

Okay, I've reworked my patch in that way that I've additionaly removed the protected FUser and FPassword variables. The User and Password properties are now setting and getting the coresponding connection properties. After login dialog is closed the private procedure which set the username and passw...

From my point of view I expect that the properties user and password allways contain the current values which are either set by the program or modified by the login prompt. Otherwise they are useless because it's impossible to determine which username is currently used.

Currently the username and password properties are not updated if they were changed in the login dialog. So I've modified procedure TZConnection.Connect; var //Local variables declared in order to preserve the original property value //and to avoid the storage of password Username, Password: string;...
