How to create dynamic length Json array in Groovy

I am using Groovy in Soap UI. I have requirement to create dynamic JSON
array. Let's say I am getting an count as 12, then I need to create
a JSON Array as {["ID": 1234,"Desc":"Apple"]} and I have to repeat
ID and Desc with different values to create 12 array object in
single JSON.
def IDValue = ... // One Array where all IDs are stored
def Description = ... // Second Array where all desc are stored
JsonBuilder builder = new JsonBuilder()
for(int i=0; i<Array.length; i++) {
def currIDValue = IDValue[i]
def currDescription =Description[i]
builder{Details([i].collect{[id : currIDValue,"Desc": currDescription]})}
}
Log.info builder.toPrettyString()
While print only last value is coming of both the array in JSON I have
wanted all the values should come in JSON as JSON objects in Detail
array

You can transpose the two arrays and then collect over the resulting
pairs. E.g.
def ids = [1,2,3,]
def descs = ["a", "b", "c",]
[ids, descs].transpose().collect{ id, desc -> [id: id, desc: desc] }
// → [[id:1, desc:a], [id:2, desc:b], [id:3, desc:c]]

​Does this helps you :
import groovy.json.*
def IDValue = [1,2,3,4]
def Description = ["decs1","decs2","decs3","decs4"]
def array=[]
for(int i=0; i<3; i++) {
array+=["Id": IDValue[i], "Desc":Description[i]]
}
JsonBuilder builder = new JsonBuilder(array)
println builder.toPrettyString()​

Android database table data to specific model object

I have sqlite database with table 'data' as
uid type name value
1 abc North 10
1 abc South 0
1 abc East 0
1 abc West 0
1 abc Total 10
1 xyz Total 20
1 xyz Open 10
1 xyz Close 10
Using select query I am able to get this table data, now I need to create response object having following structure
DataModel(String type, Arraylist<Data> data)
Data(String name, String value)
expected output json will be
{"data":[{"type":"abc", "values":[{"name":"North", "value":"10"}, {"name":"South", "value":"0"}...]},
{"type":"xyz", "values":[{"name":"total", "value":"20"}, {"name":"open", "value":"10"}...]}]}
for now I tried this kotlin code in android studio & its working well 'result' Arraylist contains above table data
val dataList: ArrayList<DashboardDataModel> = ArrayList()
val typeAyyList: ArrayList<String> = ArrayList()
for(res in result){
typeAyyList.add(res.type)
}
val distinct = typeAyyList.toSet().toList()
for(type in distinct) {
val values: ArrayList<DashboardData> = ArrayList()
for (res in result) {
if (type == res.type) {
val dash=DashboardData()
dash.name=res.name
dash.value=res.value
values.add(dash)
}
}
val data = DashboardDataModel()
data.type=type
data.values=values
dataList.add(data)
}
Is there any better solution available?
Any help/suggestion please?

How to read from mysql and write column wise in csv file?

I have different tables in a database(say mysql). i need to extract some columns from different table and write it in a csv file. consider table 1
A 1
B 2
C 3
table 2 table 3
X 7 AB A1
Y 8 BC B2
Z 10 CD C3
U 11 DE D4
V 12
W 13
i want to write 1st column from table 1,2nd col from table 2, and 1st col from table 3 in a csv file such that empty rows are made null.
output:
A,7,AB
B,8.BC
C,10,CD
null,11,DE
null,12,null
null,13,null
i can do the basic reading and writing from mysql to csv, need help in the logic or code to get the above output. "Looking for a generic solution for say 'n' number of columns from 'n' number of tables". above is jus a example.

I do not know how you read your database but assume you do it with JDBC:
ResultSet tableAReusltSet= null;
ResultSet tableBReusltSet= null;
ResultSet tableCReusltSet= null;
List<PseudeContainer> container = new ArrayList<>();
while (tableAReusltSet.next()) {
PseudeConteiner ps = new PseudoContainer();
ps.col1 = tableAReusltSet.getString("ColumnName");
container.add(ps);
}
int i = 0;
while (tableBReusltSet.next()) {
if(container.size() <= i){
container.add(new PseudeContainer());
}
container.get(i).col2 = tableBReusltSet.getString("ColumnName");
}
i = 0;
while (tableBReusltSet.next()) {
if(container.size() <= i){
container.add(new PseudeContainer());
}
container.get(i).col2 = tableBReusltSet.getString("ColumnName");
}
//.. now you have a collection to work with which you can write
public PseudeContainer {
String col1 = null;
String col2 = null;
String col3 = null;
}
Above should work.. still pseudo code...

Since you just want the logic here is some pseudo code that may help you in whatever language you are using. Since I don't know how you are exporting to csv I made it pretty generic.
arr1 = select column1 from table1;
arr2 = select column2 from table2;
arr3 = select column1 from table3;
max = isBigger(arr1.length, arr2.length);
max = isBigger(max, arr3.length);
for(i=0; i<max; i++)
{
if(arr1[i]=="") arr1[i]=null;
if(arr2[i]=="") arr2[i]=null;
if(arr3[i]=="") arr3[i]=null;
print arr1[i] + "," + arr2[i] + "," + arr3[i];
}

mysql query in clause at playframework

in below two sql query sql1 not selecting any row, and sql2 selecting only 1 for 111#k2.com
var ids="'111#k2.com','222#k2.com','333#k2.com','444#k2.com','555#k2.com','666#k2.com'"
val sql1 = SQL("SELECT id,point,privacy FROM `pointTable` WHERE state=1 and id in ({users})").on("users" -> ids)
sql1().map { row =>
val point = if (row[Boolean]("privacy")) { row[Double]("point").toString } else { "0" }
println(write(Map("id" -> row[String]("id"), "point" -> point)))
}
val sql2 = SQL("SELECT id,point,privacy FROM `pointTable` WHERE state=1 and id in (" + ids + ")")
sql2().map { row =>
val point = if (row[Boolean]("privacy")) { row[Double]("point").toString } else { "0" }
println(write(Map("id" -> row[String]("id"), "point" -> point)))
}
in phpmyadmin when i run this query manualy it returns 6 rows then why not working perfectly here.
i am using play framework 2.2 with scala 2.1

That's not going to work. Passing users though on is going to escape the entire string, so it's going to appear as one value instead of a list. Anorm in Play 2.3 actually allows you to pass lists as parameters, but here you'll have to work around that.
val ids: List[String] = List("111#k2.com", "222#k2.com", "333#k2.com")
val indexedIds: List[(String, Int)] = ids.zipWithIndex
// Create a bunch of parameter tokens for the IN clause.. {id_0}, {id_1}, ..
val tokens: String = indexedIds.map{ case (id, index) => s"{id_${index}}" }.mkString(", ")
// Create the parameter bindings for the tokens
val parameters = indexedIds.map{ case (id, index) => (s"id_${index}" -> toParameterValue(id)) }
val sql1 = SQL(s"SELECT id,point,privacy FROM `pointTable` WHERE state=1 and id in (${tokens})")
.on(parameters: _ *)

How can I port PHP preg_split to Java for the special case of unserializing a value in ADODB?

I need to port this function for unserializing a value in ADODB to Java.
$variables = array( );
$a = preg_split( "/(\w+)\|/", $serialized_string, -1, PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE );
for( $i = 0; $i < count( $a ); $i = $i+2 ) {
$variables[$a[$i]] = unserialize( $a[$i+1] );
}
I have a library to unserialize the values the php way, but I need help on porting over the preg_split. What would this regex look like in Java?

Equivalent java code :
import java.util.List;
import java.util.ArrayList;
// Test
String serialized_string = "foo|bar|coco123||cool|||";
// Split the test
String[] raw_results=serialized_string.split("\\|");// Trailing empty strings are removed but not internal ones
// Cleansing of the results
List<String> php_like_results = new ArrayList<String>();
for(String tmp : raw_results) {
if (tmp.length()>0) {
php_like_results.add(tmp);
}
}
// Output results
System.out.println(php_like_results);
This will produce :
[foo, bar, coco123, cool]
