Also can you explain this part:
d[NR] = a[1]; l[NR] = a[2]; n[NR] = ($3 == "NOT NULL")
if(((d[i] == "Numeric" && (($i + 0) == $i || $i == "")) || d[i] == "String") && (length($i) <= l[i]) && (length($i) >= n[i]))

These 2 lines are the login part...
1st line is assignment part for schema file
2nd line is the validation part from schema

Hi,
One more thing. If i want to have the column header in the goodrec file by referring to the cf.txt file, how can i do it.

Expected result:
Quote:
id,name,state,street_No
22,Lilly,CA,405
55,Taylor,GI,3333
77,,FL,22
Where my cf.txt file is
Quote:
id,Numeric(2),NOT NULL
name,String(20)
state,String(10),NOT NULL
street_No,Numeric(4)
Thanks,
Shree

Code:
awk -F "," 'NR == FNR {h = (h == "") ? $1 : (h FS $1); gsub("[)(]", "-", $2); split($2, a, "-"); d[NR] = a[1]; l[NR] = a[2]; n[NR] = ($3 == "NOT NULL") ? 1 : 0; next}
  FNR == 1 {print h > "goodrec"}
 {for(i = 1; i <= NF; i++)
  {if(((d[i] == "Numeric" && (($i + 0) == $i || $i == "")) || d[i] == "String") && (length($i) <= l[i]) && (length($i) >= n[i]))
      {f = 1} else {f = 0};
    if(f == 0) {print $0 > "badrec"; next}} print $0 > "goodrec"}' cf.txt df.txt

Hi, If i execute the below code i'm getting all the records in bad file(including good and bad records) and getting only the headers in good file. I'm not getting validated good records along with the headers in good file.
Code:
awk -F "," 'NR == FNR {h = (h == "") ? $1 : (h OFS $1); gsub("[)(]", "-", $2); split($2, a, "-"); d[NR] = a[1]; l[NR] = a[2]; n[NR] = ($3 == "NOT NULL") ? 1 : 0; next}
  FNR == 1 {print h > "goodrec"}
 {for(i = 1; i <= NF; i++)
  {if(((d[i] == "Numeric" && (($i + 0) == $i || $i == "")) || d[i] == "String") && (length($i) <= l[i]) && (length($i) >= n[i]))
      {f = 1} else {f = 0};
    if(f == 0) {print $0 > "badrec"; next}} print $0 > "goodrec"}' cf.txt df.txt

Output getting in the goodrec is :
Quote:
id,name,state,street_No
But the expected output in the goodrec is
Quote:
id,name,state,street_No
22,Lilly,CA,405
55,Taylor,GI,3333
77,,FL,22
Thanks,
Shree

I would suggest you check the input files correctly and retry
