- pgExpress Driver Params Demo
- Vita Voom Software
- -----------------------------------------------------------------------
- This is a simple demo that will search using Params to look for
- specific values in the PostgreSQL pg_type table.
-
- Notes:
- 1) For Kylix/Delphi portibility reasons, this demo Uses the CLX, not
- VCL. It might look "flickering" for VCL users. The code is similar,
- however.
- 2) Kylix and Delphi 6 do not have the TSimpleDataset component. Delphi
- 7 has TSQLClientDataset but it's on a Demos dir and not installed
- by default (Borland has discontinuated it's use). The most portable
- way to do this demo is the one presented: using a client dataset, a
- SQL dataset and a DatasetProvider.
- 3) Do not edit the pg_type table presented by default. It is a system
- table and you could be damaging your database system.
- 4) The '~~' operator found in the sdsParams query is a PostgreSQL
- operator similar to the LIKE keyword. The '%' char in the default
- search string is a ""match zero or any number of chars" char (like
- '*' on the files mask i.e. '*.*' or '*.exe''.
