Hi Aigles,

Thanks for your help ,script is working fine.I need some additional modifcation on the script

If string data lenghth below 50 ,set string default length to 50 ,if between 50 to lessthan 100,set default data length to 100
If between 100 to less than 200 ,set default length to 500

If between 500 to less than 1000,set default length 1000.

Numbers data length ,no issue ,set to 38 whatvery length comes

If there is spaces or no value at the last column ,script to remove those values .
Code:
ex:
col1|col2|col3|col4|
xx|xx1|5566|8999|

Thanks in advance
MR

Try and adapt this new version (not tested)
Code:
awk -F'|' '
BEGIN {
   colDefaultLength = 1;
}
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 ( $c ~ /^ *$/ )                     continue;
           if ( $c ~ /^[0-9]+$/        )          colIsNum[c]++
      else if ( $c ~ /^[0-9]*\.[0-9]*$/ )         colIsDec[c]++
      else if ( $c ~ /^[0-9]+\/[0-9]+\/[0-9]+$/ ) colIsDat[c]++
      else                                        colIsTxt[c]++;
   }
}
END {
   print "create table tablename("
   for ( c=1; c<=colCount; 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 ( colIsDat[c] ) out = out " date"
      else if ( colIsDec[c] ) out = out " number(38,4)"
      else if ( colIsNum[c] ) out = out " number(" colLength[c] ")"
      else                    out = out " varchar2(" var2Len ")";
      if ( c != colCount ) out = out ",";

      print out

Hi Aigles,

The script workinf fine if last filed is null and data also null(After col4) ,if any column data also null,its giving Error data type .For Instance for 2 column having null values ,when executing the script its giving Error data type.Is there any way to check only last field column name ,if column name exist and then no data set string 5o or if no column name and no data,consider upto col4.Your help is greatly appreciated.

Code:
col1|col2|col3|col4|
xxx| |10/08/2003|234506|
yyy| |12/03/2003|345678|

output
Code:
 
create table (col1 varchar2(50),
                  col2 Error!,
                  col3 date,
                  col4 number)

Are you sure of your script ?
The string 'Error!' doesn't exist in the script.
When I execute the script of my last post with your last sample datas, the result is :
Code:
create table tablename(
  col1 varchar2(50),
  col2 varchar2(50),
  col3 date,
  col4 number(6)
);

A new version !
- Column name and no data -> Varchar2(50)
- No column name and datas -> column name set by the scriipt = Column<#column>
- No column name and no data -> column ignored
Code:
awk -F'|' '
BEGIN {
   colDefaultLength = 1;
}
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 ( $c ~ /^ *$/ )                     continue;
           if ( $c ~ /^[0-9]+$/        )          colIsNum[c]++
      else if ( $c ~ /^[0-9]*\.[0-9]*$/ )         colIsDec[c]++
      else if ( $c ~ /^[0-9]+\/[0-9]+\/[0-9]+$/ ) colIsDat[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 ( colIsDat[c] ) out = out " date"
      else if ( colIsDec[c] ) out = out " number(38,4)"
      else if ( colIsNum[c] ) out = out " number(" colLength[c] ")"
      else                    out = out " varchar2(" var2Len ")";
      if ( c != colCount ) out = out ",";

      print out

   }
   print ");";
}
' inputfile

Inputfile
Code:
MyCol1|MyCol2|||MyCol5|MyCol6|
xxx| |111||10/08/2003|234506|
yyy| |222||12/03/2003|345678|

Result:
Code:
create table tablename(
  MyCol1 varchar2(50),
  MyCol2 varchar2(50),
  Column3 number(3),
  MyCol5 date,
  MyCol6 number(6)
