i have two table, one for project name and the type of project like this

Project

ID     project_name
         
1      project one
2      project two
3      project three

Type

typeid          ID     type_project   minprice         maxprice
1        1        residential     2,717,000.00      4,197,000.00
2        1      commercial     408,000.00        983,000.00
3        1      industrial       399,600.00       1,000,000.00

5        2      residential     263,000.00        2,267,000.00
6        3      commercial       194,700.00        341,500.00

my query is
Select * from project,type where type.minprice >= 500000 and type.maxprice <= 1000000 and project.ID = type.ID order by project.project_name asc"

it should display these:

2     1      commercial     408,000.00     983,000.00 = because 983,000.00 is less than 1000000

3     1      industrial    399,600.00          1,000,000.00  = because 1,000,000.00 is equal to 1000000

4     2      commercial     691,000.00         2,273,500.00 = because 691,000.00 is less than 1000000

SELECT Type.typeID, Project.ID, Type.type_project, Type.minprice, Type.maxprice

FROM Type INNER JOIN Project ON Type.ID = Project.ID

WHERE (Type.minprice >= 500000 AND Type.maxprice <= 1000000)

ORDER BY Project.project_name;

It is always better for security and performance not to use the "*" wildcard in database select statements. Otherwise, the INNER JOIN is a more graceful way of connecting your two tables- where all records with matching values will be returned.
