Try this new version:
Code:
file=$1
table=$2
awk -F'|' '

BEGIN {
   colDefaultLength = 1;

   dat1Re = "[0-9]+\/[0-9]+\/[0-9]+";
   dat2Re = "[12][0-9][0-9][0-9][01][0-9][0-3][0-9]";

   datRe  = "^\(" dat1Re "|" dat2Re "\)$";
   nulRe  = "^[[:space:]]*$";
   numRe  = "^[0-9]+$"; 
   decRe  = "^\([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+\)$";

}

{ sub(/\r$/, "") }

NR==1 {
   for ( c=1; c<=NF; c++ ) {
      colName[c] = $c;
   }
   colCount = NF;
   if (!colName[colCount]) colCount--;
   next;
}

{
   for ( c=1; c<=NF; c++ ) {
      if (length($c) > colLength[c]) colLength[c] = length($c);
           if ( $c ~ nulRe    )   continue;
           if ( $c ~ datRe    )   colIsDat[c]++ 
      else if ( $c ~ numRe    )   colIsNum[c]++
      else if ( $c ~ decRe    )   colIsDec[c]++
      else                        colIsTxt[c]++;
   }
}

END {
   print "create table " TableName "("
   for ( c=1; c<=colCount; c++ ) {

      if ( colName[c] == "" ) {
         if (colLength[c]+0 == 0) {
            continue;
         } else {
            colName[c] = "Column" c;
         }
      }


      if ( colLength[c]+0 == 0 ) colLength[c] = colDefaultLength;
      var2Len = colLength[c];
           if (var2Len <   50) var2Len = 50
      else if (var2Len <  100) var2Len = 100
      else if (var2Len <  500) var2Len = 500
      else if (var2Len < 1000) var2Len = 1000;

      out = "  " colName[c];
           if ( colIsTxt[c] ) out = out " varchar2(" var2Len ")"
      else if ( colIsDec[c] ) out = out " number(38,4)"
      else if ( colIsNum[c] ) out = out " number(" colLength[c] ")"
      else if ( colIsDat[c] ) out = out " date"
      else                    out = out " varchar2(" var2Len ")";
      if ( c != colCount ) out = out ",";

      print out

   }
   print ");";
}

' TableName=$table $file

Input file:
Code:
COL1_NUM|COL2_NUM|COL3_TXT|COL4_TXT|COL5_TXT|COL6_DAT|COL7_DEC|
20100708|766|XXX|XXXX-YYYY/Z||10/05/2010|.4
12345|1234|123|01/01/2001||20050607|12.8

Output:
Code:
create table (
  COL1_NUM number(8),
  COL2_NUM number(4),
  COL3_TXT varchar2(50),
  COL4_TXT varchar2(50),
  COL5_TXT varchar2(50),
  COL6_DAT date,
  COL7_DEC number(38,4)
);

The AIX awk doesn't product any message.
These messages are specific tho gawk (GNU awk) :

Modify the script :
Code:
   dat1Re = "[0-9]+/[0-9]+/[0-9]+";
   dat2Re = "[12][0-9][0-9][0-9][01][0-9][0-3][0-9]";

   datRe  = "^(" dat1Re "|" dat2Re ")$";
   nulRe  = "^[[:space:]]*$";
   numRe  = "^[0-9]+$"; 
   decRe  = "^\([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+\)$";
