DBD::mysqlPP::st execute_array failed: #23000Column 'c_type' cannot be nul l err was 1048 now 2000000000 executing 200 generated 100 errors at D:\Project\Tools\my_tool.pl line 463, <BATCH> line 1. 

$insert = $dbh->prepare("INSERT INTO $table_name(s_no,c_type,jur,home,
+lni,citation,d_pattern,d_text) VALUES(?,?,?,?,?,?,?,?) ON DUPLICATE K
+EY UPDATE s_no = s_no,c_type = c_type, jur = jur, home = home, lni = 
+lni,citation =citation,d_pattern= d_pattern,d_text= d_text") ;
                                my $input_tuples = $insert->execute_ar
+ray({ ArrayTupleStatus => \my @tuple_status },\@index_array,\@c_array
