For poker fans: All possible seven card combinations in a database

I have created a script that puts all possible seven card combinations in Texas Holdem poker into an SQLite database. It could be useful to do some calculations. The database becomes several gigabytes big and very slow on personal computers. But in future with faster PCs this solution could be great. This script needs an SQLite database with 7 columns called tables.db. Please find the Python code below:

import numpy

arrayt=[102,103,104,105,106,107,108,109,110,111,112,113,114,202,203,204,205,206,207,208,209,210,211,212,213,214,302,303,304,305,306,307,308,309,310,311,312,313,314,402,403,404,405,406,407,408,409,410,411,412,413,414]

conn=sqlite3.connect('tables.db')
c=conn.cursor()
pos1=0
pos2=1
pos3=2
pos4=3
pos5=4
pos6=5
pos7=6
i=0
while pos1<=45:
   
    while pos2<=46:
       
        while pos3<=47:  
               
            while pos4<=48:
               
                while pos5<=49:    
                   
                    while pos6<=50:
                       
                        while pos7<=51:
                            c.execute("INSERT INTO TABLE2 VALUES (?, ?, ?, ?, ?, ?, ?)", ((arrayt[pos1]),(arrayt[pos2]),(arrayt[pos3]),(arrayt[pos4]),(arrayt[pos5]),(arrayt[pos6]),(arrayt[pos6])))   
                            pos7+=1
                            i+=1
                        pos6+=1
                        pos7=pos6+1
                    pos5+=1
                    pos6=pos5  
                pos4+=1
                pos5=pos4
            pos3+=1
            pos4=pos3    
        pos2+=1
        pos3=pos2
    pos1+=1
    pos2=pos1
conn.commit()
conn.close()
