The above solution is working fine for the configuration(cf.txt) and data (df.txt)files where it is validating the datatypes of the data file by referring to configuration file. And my cf.txt was
id,Numeric
name,String
state,String
street_No,Numeric

Suppose if i have a configuration file cf.txt which looks like below:
Code:
id,Numeric(2),NOT NULL
name,String(20)
state,String(10),NOT NULL
street_No,Numeric(4)

Here i wanted to validate datatype, field length and nullable values.

And if my datafile df.txt looks like below :
Code:
abc,john,MI,201
22,Lilly,CA,405
33,Richard,CA,21Q
444,Reet5,NY,258
55,Taylor,GI,3333
66,Merry,,3333
77,,FL,22

My expected result should be in goodrec is
Code:
22,Lilly,CA,405
55,Taylor,GI,3333
77,,FL,22

In badrec i should get
Code:
abc,john,MI,201
33,Richard,CA,21Q
444,Reet5,NY,258
66,Merry,,3333

Here i need to check the datatype, field length and nullable values.How i can modify the below code to achieve it?
Code:
awk -F "," 'NR == FNR {a[NR] = $2; next} {for(i = 1; i <= NF; i++) {if((a[i] == "Numeric" && ($i + 0) == $i) || (a[i] == "String" && $i != "")) {f = 1} else {f = 0};if(f == 0) {print $0 > "badrec"; next}} print $0 > "goodrec"}' cf.txt df.txt
