string-manipulation

Hello

I have some data in the format of

C222 = 50
C1234P687 = 'some text'
C123YYY = 'text'
C444 = 89
C345 = 3
C122P687 = 'some text'
C122YYY = 'text'
....
....

so basically 3 different forms

"C" number = value, example - C444 = 89
"C" number "P" number = value, example - C123P687 = 'some text'
"C" number "YYY" = value

Only number is of variable length on the left side of (=) sign. Values vary.

I want to store the data in db as

INSERT INTO datatable 
    c_id = "number after C"
    p_id = "number after P" // if it exists for a line of data
    value = 'value'
    yyy = 'value'

Any ideas how to retrieve these numbers?

Thanks
