Creating a Chart From a Table

,

This procedure creates a visual display of your table data. The result is an html file in

the c: directory. Example picture is below:

weight
height
years
iq

Ann
Joe
Mark
Tom

First put all downloaded files put in C: directory (only htm and jpg). Then you have to create procedure psoHTML.

Data for charts are from table which is created by us, but it must satisfy some rules. First column is primary key - varchar and it represent object. Other columns must be integer and they are properties of objects. The name of column represent column property. For example objects can be persons and properties are weight, height, years,

etc. When data is inserted in the table we call call procedure with parameters (name of table and name of new html file), result is new created file with that name in directory C: (please don't forget to copy files to directory C:). This procedure is limited to 4 object but you can

easily upgrade it to more with basic

knowledge of graphical utilities.

Here is the stored procedure:

Example 1

CREATE TABLE pso1
(
object varchar(15) PRIMARY KEY,
property1 int,
property2 int,
property3 int,
property4 int,
property5 int,
property6 int
)
INSERT INTO pso1 VALUES ('FIRST OBJECT',180,100,27,120,2,1000);
INSERT INTO pso1 VALUES ('SECOND OBJECT',80,500,67,20,32,100);
EXEC psoHTML 'pso1', 'demo1'

There is new file in directory C: with name demo1.htm (C:\demo1.htm)

Example 2

CREATE TABLE pso
(
person varchar(15) PRIMARY KEY,
weight int,
height int,
years int,
iq int
)
INSERT INTO pso VALUES ('Tom','180','100','27','120');
INSERT INTO pso VALUES ('Ann','130','45','15','130');
INSERT INTO pso VALUES ('Joe','60','20','10','80');
INSERT INTO pso VALUES ('Mark','207','150','35','90');
EXEC psoHTML 'pso', 'demo2'

There is new file in directory C: with name demo2.htm (C:\demo2.htm).
