sql - Crystal Reports: Link table from formula field -


i need find out if can link 2 unrelated tables via formula field in crystal reports. can done? if not, need figuring out solution.

details:

table_a contains string "comment" field. comment field contains random words , unique invoice number. have created formula field within crystal split out unique invoice number, data ready linked table_b via unique number, if possible. haven't found way proceed, , don't think it's possible.

in case not possible, suppose need pull necessary data table_a, split out invoice number, , create temporary table prior pulling data , table_b crystal, correct? while have basic sql experience, have no idea how go doing that. appreciated.

i'm on crystal xi , use mas 200 erp 4.4

thanks in advance.

not directly, no.

options:

  • use subreport - 1 table in main report, other in subreport; create formula field convert 1 of field's value match other; link on field
  • create sql view work; use view instead of 2 tables
  • use command link 2 tables
