how to reduce the rework on Informatica ETLs due to change of table and column names -

-

currently, have lot of etls developed , underlying table , column names going change. example, physical names used abbreviated names rather full names since wanted deploy on oracle, now, decided use sql server, hence there discussion on using full names @ db level. impact etls have developed.

i wondering whether there efficient way remap etl changed column names? can provide file old , new table/column names input.

any on appreciated.

one possible way use sql override value in of source qualifier transformations contains sql query parameter file substitutions. way can change column names , select them in mapping sources without modifying source definitions. of course require up-front refactoring of existing source qualifier transformations.

alternatively, @ database level create views onto existing tables use old abbreviated column names, providing translation between new column name , old one. not require changes existing etl.

however, advise against changing in case, since difference purely cosmetic - produce maintenance , complexity headaches.

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
