PGACCESS 0.93 10 December 1998 |
||||
================================ |
||||
I dedicate this program to my little daughters Ana-Maria and Emilia and to my |
||||
wife for their understanding. I hope they will forgive me for spending so many |
||||
time far from them. |
||||
|
||||
|
||||
|
||||
1.Why PgAccess ? |
||||
|
||||
First of all because PostgreSQL lacks a graphical interface where you |
||||
can manage your tables, edit them, define queries, sequences and |
||||
functions. |
||||
|
||||
I use Tcl/Tk because it's a powerful language, and it took me only |
||||
four days of hard work to get it as you see it now. |
||||
|
||||
|
||||
|
||||
2.How to INSTALL ? |
||||
|
||||
You will need Tcl/Tk package, I am using now Tcl 7.6 and Tk 4.2. |
||||
PgAccess is running fine also on Tcl/Tk 8.0 |
||||
|
||||
Also, you will need the PostgreSQL to Tcl interface library, lined as a |
||||
Tcl/Tk 'load'-able module. It is called libpgtcl and the source is |
||||
located in the PostgreSQL directory /src/interfaces/libpgtcl. |
||||
Specifically, you will need a libpgtcl library that is 'load'-able from |
||||
Tcl/Tk. This is technically different from an ordinary PostgreSQL |
||||
loadable object file, because libpgtcl is a collection of object files. |
||||
|
||||
Under Linux, this is called libpgtcl.so. You will find a pre-compiled |
||||
copy of it for Linux i386 systems at : http://www.flex.ro/pgaccess. |
||||
Just copy libpgtcl.so into your system library directory /usr/lib or |
||||
/lib and go for it. |
||||
|
||||
Under Windows, copy libpgtcl.dll and libpq.dll into C:\WINDOWS\SYSTEM directory. |
||||
Make sure you have Tcl/Tk at least version 8.0.0 for Microsoft Windows 95 & NT. |
||||
PgAccess has been checked with Tcl/Tk 8.0.4 version on Windows95 and Windows98 |
||||
platforms. |
||||
|
||||
Tcl/Tk 8.0.4 for Windows95 & NT can be downloaded from |
||||
ftp://ftp.scriptics.com/pub/tcl/tcl8_0/tcl804.exe |
||||
It is 1833712 bytes long. |
||||
|
||||
|
||||
3.How to run it? |
||||
|
||||
You run it with the command: |
||||
|
||||
wish -f pgaccess.tcl [database] |
||||
|
||||
[database] is optional. |
||||
|
||||
Another way of loading the PostgreSQL library is running it with pgwish. |
||||
It's a wish compiled with libpgtcl library so it could understand the |
||||
commands for working with PostgreSQL. For this, remove the line "load |
||||
libpgtcl.so" from the source. If your operating system has a different |
||||
library name or location, change the 'load libpgtcl.so' line in the |
||||
pgaccess.tcl file. |
||||
|
||||
|
||||
4.What does it now ? |
||||
|
||||
- Opens any database on a specified host at the specified port, username and password |
||||
- Perform vacuum command. |
||||
- Saves preferences in ~/.pgaccessrc file |
||||
|
||||
Tables |
||||
- opening multiple tables for viewing, max n records (configurable) |
||||
- column resizing by dragging the vertical grid lines |
||||
- text will wrap in cells now |
||||
- dynamic row height when editing |
||||
- table layout saved for every table |
||||
- import/export to external files (SDF,CSV) |
||||
- filter capabilities ,enter filter like price>3.14 |
||||
- sort order capabilities ,enter manually the sort field(s) |
||||
- editing in place, double click the text you want to change |
||||
- record deleting , point the record, press Del key |
||||
- adding new records ,save new row with right-button-click on table for the moment |
||||
- table generator assistant |
||||
- table renaming and deleting (dropping) |
||||
- table information retrieving : owner, field information, indexes |
||||
|
||||
Queries |
||||
- define, edit and store "user defined queries" |
||||
- save view layout |
||||
- can store queries as views |
||||
- execution of queries with optional user input parameters ( select * from invoices where year=[parameter "Year of selection"] ) |
||||
- viewing of select type queries result |
||||
- running action queries (insert, update, delete) |
||||
- visual query builder with drag & drop support, table aliasing |
||||
|
||||
Sequences |
||||
- define |
||||
- inspect |
||||
- delete |
||||
|
||||
Views |
||||
- defining them saving queries as views |
||||
- view them , with filtering and sorting capabilities |
||||
- delete them |
||||
|
||||
Functions |
||||
- define , inspect , delete |
||||
|
||||
Reports |
||||
- simple reports from a table (beta stage) |
||||
- change font,size and style of fields and labels |
||||
- load and save reports from the database |
||||
- table previews, sample postscript print |
||||
|
||||
Forms |
||||
- open user defined forms |
||||
- form design module available |
||||
- query widget allowing access to a record set |
||||
|
||||
Scripts |
||||
- define, modify and call user defined scripts |
||||
|
||||
5.What it should do in the future ? |
||||
|
||||
- sequence and function renaming |
||||
- more powerful report generator and viewer |
||||
- help on line |
||||
|
||||
|
||||
|
||||
6. How you should report the errors? |
||||
First of all : operating system, PostgreSQL version,Tcl/Tk version. |
||||
A more detailed story of what have you done when error had occurred. |
||||
Tcl/Tk stops usually with a error message and there is a button there |
||||
"Stack Trace" and if you press it, you will see a detailed information |
||||
about the place where it stuck. Please send it to me. |
||||
Some information about table structure, no. of fields, records would |
||||
be also good. |
||||
