Error filtering multiple data using JDBC and javaFX

I will tell you about my problem. I have a database in mysql and I do the queries from Java using javafx and JDBC. I am trying to do a data filter, since I want to be able to filter data not only by name, but also by other data. As you can see, my code has many SQL statements, I tried to put them together in an array, but only the first statement works, if I do others, exceptions are thrown, it only works if I do only 1 individual query. My problem is that and I would like to find a solution. I have a lot of silenced code, since my idea is to have a statement that encompasses everything.

How can I set the x-axis and y-axis in charts

Mocking private method inside a public method

I've made a test of a getStudies method, that has a private method call inside itself. Now, how to mock that call in a test method (see down below)?
It's on a second line in a method for testing String query = setQueryForChangingState(filterParams);. I'll provide additional code, if necessary.
Method for testing
public Object getStudies(FilterInputModel filterParams) {
String query = setQueryForChangingState(filterParams);
logger.info("Get studies query: " + query);
LinkedMultiValueMap<String, String> queryMap = new LinkedMultiValueMap<>();
queryMap.add("q", query);
return Objects.requireNonNull(webClient.post()
.uri("/query")
.header(HttpHeaders.AUTHORIZATION, getSessionId())
.body(BodyInserters.fromMultipartData(queryMap))
.retrieve()
.bodyToMono(QueryResponse.class)
.block())
.data;
}
Private method
private String setQueryForChangingState(FilterInputModel filterParams) {
String query = "SELECT id, " +
"basf_study_id__cr.name__v, " +
"name__v, " +
"state__v, " +

"AND state__v = 'study_setup_completed_state__c'";
if (!filterParams.getCores().isEmpty()) {
query = query + " AND bas_core__c CONTAINS('" + String.join("','", filterParams.getCores()) + "')";
}
if (!filterParams.getStudyStartDate().isEmpty()) {
if (filterParams.getStudyStartDate().size() == 1) {
query = query + " AND study_start_date__c = '" + filterParams.getStudyStartDate().get(0) + "'";
} else if (filterParams.getStudyStartDate().size() == 2) {

} else {
logger.info("Date range has to many inputs!");
}
}
return query;
}
My test
#Test

String body = Files.read(filePath.toFile(), Charset.defaultCharset());

Object response = vaultServiceTest.getStudies(inputModel);
QueryResponse jsonBody = new ObjectMapper().readValue(body, QueryResponse.class);
assertEquals(response, jsonBody.data);
I guess it could be done, but I'm not sure how.

where rsParameters is class level and is fetched before. After first

with resource block? Please help

Your rsParameters parameter is of Type Resultset.
In first iteration, after try{} block is complete close() method of rsParameters:ResultSet is called.
This internally makes all the properties of resultSet NUll.
That is the reason for getting Null properties during second iteration.

Java strange variable assignment enquiry

I've come across a weird situation. The code is as below:
public static int add(String trcd, String tlcd, String dept, String doDate,
String doTime, String andConfirm, Teller admin) throws
Exception {
try {
String table1 = "table1";
String table2 = "table2";
String trap = null;
String trtype = null;
String sql = "select * from " + table2;
DataSet dataset = DBOper.DBQuery("taUtil", sql);
if (dataset.isEmpty()) {
return -1;
}
else {
HashMap map = dataset.getRow(0);
trap = (String) map.get("aut_ap_code");
trtype = (String) map.get("aut_type_code");
//point 1
sql = "insert into " + table1 + " values("+trtype + "','" + doDate + "','" + doTime + "','N','Y')";
DBOper.DBUpdate("taUtil", sql);
if (andConfirm.equals("Y")) {
//point 2
sql = "select * " + table1 +" where tr_create_date='" + doDate + "' and tr_create_time='" + doTime + "' and tr_stcd='Y'";
//point 3
DataSet dataset2 = DBOper.DBQuery("taUtil", sql);
if (dataset2.isEmpty()) {
return -2;
}
else {
String trNo = null;
HashMap map2 = dataset2.getRow(0);
trNo = (String) map2.get("tr_no");
confirm(admin, trNo, "N");
}
}
return 0;
}
}
catch (Exception e) {
throw e;
}
}
The problem is:
at point 3, it
always prints "insert" ie the previous sql value instead of the latest assignment of "select".
Does anybody knows why is it so ?
Thanks

You have a syntax error in your assignment statement:
sql = "insert into " + table1 + " values(trtype + "','" + doDate + "','" + doTime + "','N','Y')";
Try to replace it with:
sql = "insert into " + table1 + " values(" +trtype + "',' " + doDate + "','" + doTime + "','N','Y')";
I'm not sure how you even managed to compile this...
EDIT: If this syntax error does stop the code from compiling and your IDE (assuming you are using one) executes older version of the class that could not be compiled (has happened to me using Eclipse on occasions), I think it could end up doing something completely unpredictable and possibly explain this odd behavior.
