Splitting the string , mapping and building the sql in java

I have some task to do and can't figure out how to reach the result.
For example i have some STRING like this :
key1=value1&key2=value2|key3=value3
This string like key=value with options AND or OR.
I have also some map that contains following things:
key1=ke1Mapped; key2=key2Mapped; key3=key3Mapped;
I want to build some sql Select * from table1 where
And insert mapped keys and its values, but also to take into account & and | , i.e. AND or OR to use in sql query when it's needed.
Actually, finally sql query should be:
Select * from table where ke1Mapped=value1 AND key2Mapped=value2 OR key3Mapped=value3
I tried to split the main string and convert to MAP and then to loop over the list of mapped values and build dynamically sql. But i don't know what is AND or OR.
Tried to push it in two stacks , also were complicated.
I try now to understand how to build only architecture of this flow. And can't figure out what approach is needed here.
Anyone can suggest something?
Thanks

How to store listed values from a database to variables in Anylogic 8.7.1?

I am creating an agent based model in Anylogic 8.7. There is a point that I want to use query to get a List of values from a database table(rs_table) with a condition, here is the Java code that anylogic writes at the designated place:
(int) selectFrom(rs_table) .where(rs_table.tr.eq(1)) .list(rs_table.impact)
but I do not know how to store those values and how to reach them one by one. I would be grateful if you help me out thanks.

I would use a collection. Add a collection element from the "Agent" Pallet. The collection should have the following properties:
Collection Class: LinkedList
Element Class: Int
Use the following code:
collection.addAll(
selectFrom(rs_table) .where(rs_table.tr.eq(1)) .list(rs_table.impact)
);
Now, you can access the value from the collection as follows:
collection.get(i);

The "Iterate over returned rows and do something" option of the Insert Database Query wizard is precisely designed for this. It produces query code that loops through the returned list and prints each column's value to the console (via a traceln call); you just replace the code within the loop with what you actually want to do for each returned row (where the template code shows you how to get the value of each column in the row).
The wizard (if you use the QueryDSL form) will produce code like below:
List<Tuple> rows = selectFrom(rs_table)
.where(rs_table.tr.eq(1))
.list();
for (Tuple row : rows) {
traceln(
row.get( rs_table.tr ) + "\t" +
row.get( rs_table.impact )
);
}
(with extra row.get lines for any other table columns beyond the tr and impact ones).
(In Java terms, the query's list function returns a List of Tuple objects as the code shows.)

JDBI: How to map query as list of objects

I am using JDBI to iterate through a resultset via streams. Currently mapToMap is causing problems when there is a column with the same name in the result. What I need is just the values without the column names.
Is there a way to map the results to an Object list/array? The docs does not have an example for this. I would like to have something like
query.mapTo(List<Object>.class).useStream(s -> { . . .})

First of all - what kind of use case would allow you not care at all about the column name but only the values? I am genuinely curious
If it does make sense, it is trivial to implement a RowMapper<List<Object>> in your case, which runs through all the columns by index and puts the results of rs.getObject(i) into a list.

Parse Query on Array Values

I'm trying to make a query to get certain objects. The thing is.. I don't know how to make a query to get object that match an array. The User can be a member of multiple Groups, so the names of these groups are stored in User.groups as an array. I am trying to get all the objects of the class 'Group' that the current user is a member of. I came up with this:
ParseQuery query1 = ParseQuery.getQuery("_User"); //selects User Class
query1.whereEqualTo("username", current_user.toString()); //selects current user
query1.include("groups"); //include 'groups' of type array with names of the groups that the user is a member of
ParseQuery query2 = ParseQuery.getQuery("Group"); //select Groups Class
query2.whereContainedIn("group_name", ?); //<-- Get objects where group_name matches a value in the User.groups
The last line of code is obviously not the way to do it. I already looked at the Parse Guide! Help is much appreciated!

After some digging and testing I came up with a solution. It wasn't that difficult actually..
ParseQuery<ParseObject> groupQuery = new ParseQuery<ParseObject> ("Group");
groupQuery.include("array");
groupQuery.whereEqualTo("array", ParseUser.getCurrentUser().getUsername());
This code selects the class 'Group' which has an array with all the usernames in it called 'members' that looks like: ["user1","user2",".."]. This array is included. The last line of code selects all the objects that the user is a member of.

fetching records from database based on variable number of inputs from from

I have a form with 8 fields and based on the values entered in them I have have to fetch the records from the DataBase. Now the problem is out of the 8 fields the user may fill any number of fields and that too in any order for example the user may fill fields 1,4 and 6 or he may fill 1 and 7 or he may fill all of them (of course he has to fill at least one field)... Now how will I write a query which will work for any number and order of input parameters? and also because this query will be used in reporting(iReport) I am not allowed to write any code with it , it has to be a SQL query. Any ideas
Thanks

there are a number of ways to do this. I have a blog post about doing something like this in a Microsoft SQL (T-SQL) stored procedure at http://code.scottshipp.com/2013/03/29/tutorial-stored-procedures-with-truly-optional-parameters/ but it is likely that you will want to do something more complex and/or you are not using MS SQL Server. You may have to write the query fragments yourself. My suggestion is to do something like the following:
Once the form is submitted, loop through the various fields in the form, and check if their values are empty or not.
For those that are not empty, add a string containing an appropriate corresponding query fragment to some collections object, like an ArrayList. Do not include "AND" or "OR" directly in this string. If you need to keep track of whether this query fragment gets "AND"ed or "OR"ed with other query fragments, track that in a separate collections object. The "query fragment" I'm talking about is what would show up in the "where __" portion of your SQL query. For instance, say the search was for someone's last name. The query fragment you add is a string that says "lastName='" + lastNameField.value() + "'".
Once you have iterated through all the various fields in the form and have a final collections object full of query fragments, construct the final SQL statement from it. Iterate through your collections object (ArrayList in this example) and connect each one with the appropriate "AND" or "OR". Say your ArrayList has the three fragments "firstName='Joe'", "middleName='Q.'", "lastName='Public'". Use a StringBuilder to keep adding these fragments together into a final where clause: "firstName='Joe' AND middleName='Q.' AND lastName='Public'"...you may want to change these to a "LIKE" style query with wildcard characters.
You now have everything you need to create the final select statement. Issue it to the database and retrieve your results!
