you can use phpmyadmin for creating tables, its easy to use it. in tables always use index, create column with named id and make it auto increment and index. with that every added row will have id, its useful sometimes.

also if you planning to create large tables with uids index uid columns it will boost the performance

about the other question:

PHP Code:

[function database test]
db.query "SELECT * FROM table WHERE uid = '<uid>' ORDER BY id DESC LIMIT 1"

SELECT * FROM: this part means select all columns (column 1, column 2)
if you want to return single column use SELECT COLUMN1 FROM

WHERE uid = '<uid>' get the row which has uid=self in uids row (put uids in seperate row)

ORDER BY id DESC: order the returning queries by id, descending, useful if you are making top15 like systems.

LIMIT 1: limit to the returning rows, always use limits because if sphere return large queries server will freeze so if you want to get the players from database which has most kills use:

[dialog d_top_15_test]
gump codes...
db.query "SELECT * FROM table WHERE columnuid = '<uid>' ORDER BY KILLS DESC LIMIT 15"
local.x=30
local.y=30
for 0 14
    ref1=<db.row.<dlocal._for>.columnuid>
    dtext <local.x> <local.y> 1152 <ref1.name>
    local.y += 20
endfor
