c - MS Access: Search through Table for the same part of the String -



c - MS Access: Search through Table for the same part of the String -

i trying loop through column values within table. have register form, provides user unique id, based uppon information. example: country = austria each user selects country republic of austria sort of unique value match (lets 00).

account id this:

xxxx00uniquecode

each country has it´s own unique value: (at = 00, de = 01, etc)

now, want generate unique code each user, increment (+1) value of previous uc value stored in table, for same country!

in order that, need somehow loop through column, business relationship ids stored , search match. thing is, when user tries generate unique code, not have yet, has only:

xxxx00

now need find xxxx00 strings in accountid column, , store them in array - find max value of , increment it.

but dont know how search part of string within column of table ? xxxx00 part, not entire business relationship id xxxx00uniquecode.

agh, hope can understand me. it´s quite complicated know, i´m stuck here. hopefully, know mean , maybe find smoother solutions this.

thanks in advance!

you're pounding square peg round hole. why not create new column called userid , can do:

select max(userid) mytable mid(accountid, 5, 2) = "00"

and increment 1.

better yet, store countrycode, userid , xxxx part in separate fields, , index them. it'll save time when search or filter, i'm assume you're going doing.
