Have you tried to use /usr/xpg4/bin/awk or gawk ?

A commented and revised version of the script :
Code:
awk '

#
# Input file #2
#

NR==FNR {                               # Select records from input file #1
   tbl[$1]++;                           #   Memorize table in in array tbl
   next;                                #   Proceed next record
}

#
# Input file #2
#

/ALTER TABLE/ {                         # Select ALTER TABLE records
   tbl_name = $3;                       #   Table name
   getcols = (tbl_name in tbl ? 1 : 0); #   Set getcols flag if table
                                        #   + found in array tbl
   next;                                #   Proceed next record
}

! getcols {                             # Select record if getcols flag not
                                        # + set to 1
   next ;                               #   Proceed next record
}

/^ADD/,/;[[:space:]]*$/ {               # Select ADD records (from ADD to
                                        # + record endig with ";"
   f = ($1 ~ /^ADD/ ? 3 : 1);           #   IF ADD record, column name is field 3
                                        #   + otherwise field 1;
                                        #   + column format is field f+1
   sub(/).*/, ")", $(f+1));             #   Remove chars after ) ending column def
   printf "%-12s %-12s %s\n", tbl_name, $f, $(f+1); #  Output table name,
                                                    #  + column name and format
}

' alisha.nam alisha.tmp

"name" file (alisha.nam):
Code:
tbla
tblc

"temp" file (alisha.tmp) :
Code:
ALTER TABLE tbla
ADD  ( cola1  VARCHAR2(11),
       cola2  VARCHAR2(12)  );

ALTER TABLE tblb
ADD  ( colb1  VARCHAR2(21),
       colb2  VARCHAR2(22)  );

ALTER TABLE tblc
ADD  ( colc1  VARCHAR2(31),
       colc2  VARCHAR2(32),
       colc3  VARCHAR2(32)  );

Output:
Code:
tbla         cola1        VARCHAR2(11)
tbla         cola2        VARCHAR2(12)
tblc         colc1        VARCHAR2(31)
tblc         colc2        VARCHAR2(32)
tblc         colc3        VARCHAR2(32)

In the first statement, replace awk with nawk, gawk or /usr/xpg4/bin/awk :
Code:
/usr/xpg4/bin/awk '

#
# Input file #2
#

NR==FNR {                               # Select records from input file #1

hi Aigles,
sorry for troubling you.
but still the code is bailing out near line containing "getcols".
# 13  
Old 07-09-2010
Try to replace
Code:
   getcols = (tbl_name in tbl ? 1 : 0); #   Set getcols flag if table
                                        #   + found in array tbl
   next;                                #   Proceed next record
}

! getcols {                             # Select record if getcols flag not
                                        # + set to 1

with
Code:
   if (tbl_name in tbl)                 #   if table found in array tbl
        getcols = 1                     #        set hetcols flag to 1
   else getcols = 0;                    #   else set getcols flag to 0
   next;                                #   Proceed next record
}

getcols != 1 {                          # Select record if getcols flag not
                                        # + set to 1

hi
i have used /usr/xpg4/bin/awk and nawk
in both cases getting error.

---------- Post updated at 08:00 AM ---------- Previous update was at 07:53 AM ----------

hi i have used your code starting with /usr/xpg4/bin/awk its giving me syntax error near lines.

Code:
/usr/xpg4/bin/awk: file "[command line]": line 16: syntax error  Context is:
>>>
>>>
>>>     next ;
>>>     /^ADD/, <<<
