Replace paritucular keywords from string exact match
i want to replace some short forms of words with its full form from decription column of one table. These short forms are stored in table .This table have columns like short_form ,long_forme.g 4wd 4 wheel drive
2wd 2 wheel drive
we have description like
1)John Deere 7210 Tractor.<br> $45,000. <br>4WD, <br>6700hrs, <br>quad range.
2)4wd,new 11.2X24 rears 7 X 16 fronts,Frey 4010S loader with quick attach bucket & forks, 3pt hitch,
3)w/9116 16" FH, 1163 6R CH, 4wd, chopper, grey cab model, Mildmay, 800-829-2672
we have to replace 4wd with 4 wheel drive [this should be taken from values stored in table] .We need to replace exact match from description column. e.g 4wd,new 11.2X24 rears 7 X 16 fronts,Frey 4010S loader with quick attach bucket & forks, 3pt hitch, should be 4 wheel drive,new 11.2X24 rears 7 X 16 fronts,Frey 4010S loader with quick attach bucket & forks, 3pt hitch,
, or any other special character should be escaped.
