Adding an 'if' statement to an AJAX process in Webmatrix - sql

Below is my code which processes an AJAX request.
Currently, when I select an area on my form page, it will send a "getresort" value to this process page, and everything works fine.
The issue comes when I don't want to search for a specific area, and instead want to display ALL resorts in ALL areas. If I select "all" in the form, it doesn't submit a value, so the WHERE clause fails as it can't get the request from the query string.
I'm assuming I need an 'if' statement in there somewhere, to check if the query string is blank, so that it runs a SQL statement that removes the WHERE AreaName = #0 part.
Where should this 'if' statement live?
#{
var db = Database.Open("StayInFlorida");
var getresortval = Request.QueryString["resval"];
var type = Request.QueryString["type"];
var res = Request.QueryString["res"];
var area = Request.QueryString["area"];
var allresorts = "SELECT ResortID, ResortName FROM ResortInfo WHERE AreaName = #0";
var qallresorts = db.Query(allresorts, getresortval);
if(type == "resortupdate") {
foreach(var row in qallresorts){
<option value='#row.ResortID'>#row.ResortName</option>
}
}

#{
var db = Database.Open("StayInFlorida");
var getresortval = Request.QueryString["resval"];
var type = Request.QueryString["type"];
var res = Request.QueryString["res"];
var area = Request.QueryString["area"];
var allresorts = "SELECT ResortID, ResortName FROM ResortInfo";
if(!getresortval.IsEmpty()){
allresorts += " WHERE AreaName = #0";
}
var qallresorts = db.Query(allresorts, getresortval);
if(type == "resortupdate") {
foreach(var row in qallresorts){
<option value='#row.ResortID'>#row.ResortName</option>
}
}

Automatically update my Gsheet with an SQL data base

I need to update a file automatically that already has data in it.
The document is filled with an SQL data base thanks to the code below
However, I want it to update itself everyday without deleting any data that are already in the document and only adding new ones (don't want any duplicates).
function readData(db, queryString) {
//connect to the database
var server = 'your-servername-OR-serverPublicIpAddress';
var username = 'your-sql-username';
var password = 'your-password';
var dbUrl = 'jdbc:sqlserver://' + server + ':1433;databaseName=' + db;
var conn = Jdbc.getConnection(dbUrl, username, password );
//query the data
var stmt = conn.createStatement();
var exec_query = stmt.executeQuery(queryString);
var metaData = exec_query.getMetaData();
var numCols = metaData.getColumnCount();
//save query data to an array
var result=[]; //initiate a blank array
//save the column header
header = []; //initiate the header row
for (var col = 0; col < numCols; col++) {
header.push(metaData.getColumnName(col + 1)); //add the name of each column to the header row
};
result.push(header);//after the header row is formed, put it to the result array
//save the data of each row
while (exec_query.next()) {
row_data = [];
for (var col = 0; col < numCols; col++) {
row_data.push(exec_query.getString(col + 1));//add data of each column to the row data
//Logger.log(row_data);
};
result.push(row_data); // add row data to result
//Logger.log(result);
};
exec_query.close();
return result
};
function pushDataToGoogleSheet(data, SheetName) {
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var sheet = SpreadsheetApp.setActiveSheet(spreadsheet.getSheetByName(SheetName));
var lastRow = sheet.getLastRow();
sheet.getRange(lastRow+1, 1, data.length, data[0].length).setValues(data);
sheet.getDataRange().removeDuplicates();
};
function main() {
db = 'YOUR_DATABASE_NAME'
SQLquery = 'YOUR_SQL_QUERY'
raw_statistics = readData(db, SQLquery); //get raw statistics
pushDataToGoogleSheet(raw_statistics, 'YOUR_SHEET_NAME'); //push to google sheet
};
function main() {
db = 'YOUR_DATABASE_NAME'
SQLquery = 'YOUR_SQL_QUERY'
raw_statistics = readData(db, SQLquery); //get raw statistics
pushDataToGoogleSheet(raw_statistics, 'YOUR_SHEET_NAME'); //push to google sheet
};
However, in the pushDataToGoogleSheet it says that it can't define the length. So, I don't know if I put the right thing for data or not or if there is an issue in my code...
Do you have an idea ?
Thank you for your help !

Problem with Session Variable value in ASP.NET Core Project. Takes the value on second time the page Loads

I have a project in which I have some Records from database in a table. So it displays 10 out of all in each page.
The User check some rows(with checkBox) and I keep those rows Id's and send them with Ajax in GetCheckedList Method when the user push Next Page Button. This methods makes the values a string and Store them as Session Variable.
The problem is that when Index takes Session Value, after GetCheckedList execution the very first time the value is Null but when User navigates for another time in Next or Previous page the Session Value on index is Correct.
Something I lose here with which method runs first but I cant figure it out and I need some help.
Index
public async Task<IActionResult> Index(...)
{
int pageSize = 10;
var users = from a in _context.Users
select a;
...
//Session variable
var checkedList = HttpContext.Session.GetString("CheckedSession");
if (checkedList != null)
{
ViewBag.checkedListVB = checkedList;
HttpContext.Session.SetString("CheckedSession1", checkedList);
}
return View(await App.PaginatedList<User>.CreateAsync(users.AsNoTracking(), pageNumber ?? 1, pageSize));
}
GetCheckedList
public RedirectResult GetCheckedList(List<string> values, string text)
{
List<string> str = values;
str.RemoveAll(item => item == null);
List<int> intList = str.ConvertAll(int.Parse);
var finalCheckList = string.Join(",", intList);
if (HttpContext.Session.GetString("CheckedSession") != null)
{
var temp = HttpContext.Session.GetString("CheckedSession");
string[] tempStringList = temp.Split(",");
var removeEmptytemp = tempStringList.Where(o => o != "").ToArray();
int[] myIntsTemp = Array.ConvertAll(removeEmptytemp, int.Parse);
List<int> myIntsTempList = myIntsTemp.ToList();
List<int> ulist = myIntsTempList.Union(intList).ToList();
var now = string.Join(",", ulist);
finalCheckList = string.Join(",",now);
}
HttpContext.Session.SetString("CheckedSession", finalCheckList);
return new RedirectResult(url: "/Users/Index", permanent: false,
preserveMethod: true);
}

How to escape _ wildcard within Google app script sql?

The function to run a standard sql query within the app script throws up an error when _is used within the sql. It is used within the condition filter to look for all names with _x_. Backslashes break the app script when used.
Within Google Apps Script: var sql1 = 'sql string';
Within sql: WHERE lower(name) like "%\_x_\%"
Update: I managed to find a workaround using REGEXP_CONTAINS(LOWER(name), r"(_x_)" but am still interested to know if it works with the regular LIKE clause.
I reproduced your case using a modified sample code from the documentation.
I queried against a sample dataset using where like "%_". Then, I write the results in a Google spreadsheet.The table I am querying in BigQuery is:
Row id
1 _id_1212
2 id1212
The code I am using is below:
/**
* Runs a BigQuery query and logs the results in a spreadsheet.
*/
function runQuery() {
// Replace this value with the project ID listed in the Google
// Cloud Platform project.
var projectId = 'project_id';
//modified query
var request = {
query: 'SELECT * from `project_id.dataset.table` where id LIKE "%_id_%";'//it will also work for where like "%\_id\_%",
//configuring the query to use StandardSQL
useLegacySql: false
};
var queryResults = BigQuery.Jobs.query(request, projectId);
var jobId = queryResults.jobReference.jobId;
// Check on status of the Query Job.
var sleepTimeMs = 500;
while (!queryResults.jobComplete) {
Utilities.sleep(sleepTimeMs);
sleepTimeMs *= 2;
queryResults = BigQuery.Jobs.getQueryResults(projectId, jobId);
}
// Get all the rows of results.
var rows = queryResults.rows;
while (queryResults.pageToken) {
queryResults = BigQuery.Jobs.getQueryResults(projectId, jobId, {
pageToken: queryResults.pageToken
});
rows = rows.concat(queryResults.rows);
}
if (rows) {
var spreadsheet = SpreadsheetApp.create('BiqQuery Results');
var sheet = spreadsheet.getActiveSheet();
// Append the headers.
var headers = queryResults.schema.fields.map(function(field) {
return field.name;
});
sheet.appendRow(headers);
// Append the results.
var data = new Array(rows.length);
for (var i = 0; i < rows.length; i++) {
var cols = rows[i].f;
data[i] = new Array(cols.length);
for (var j = 0; j < cols.length; j++) {
data[i][j] = cols[j].v;
}
}
sheet.getRange(2, 1, rows.length, headers.length).setValues(data);
Logger.log('Results spreadsheet created: %s',
spreadsheet.getUrl());
} else {
Logger.log('No rows returned.');
}
}
The output,
id
_id_1212
Both where id LIKE "%_id_%" and where id LIKE "%\_id\_%" work when I set the query to use StandardSQL (useLegacySql: false).
In addition, the error GoogleJsonResponseException: API call to bigquery.jobs.query failed with error: Syntax error: Illegal escape sequence: \_ will be thrown when trying to escape the underscore using a double backslash such as where id LIKE "%\\_id\\_%".

Rally c# task time spent

I have a C# .net application using the rally 3.0.1 API. When I query task in my system I get 0.0 for time spent when I know they have time against them. Anyone know how to get this? Below is my code:
if (uTasks.Count > 0)
{
Request taskRequest = new Request(resultChild["Tasks"]);
QueryResult TaskQueryResult = restApi.Query(taskRequest);
foreach (var items in TaskQueryResult.Results)
//foreach (var items in uTasks)
{
DataRow dtrow2;
dtrow2 = dt.NewRow();
dtrow2["TaskID"]=items["FormattedID"];
dtrow2["Task Name"] = items["Name"];
if (items["Owner"] != null)
{
var owner = items["Owner"];
String ownerref = owner["_ref"];
var ownerFetch = restApi.GetByReference(ownerref, "Name");
string strTemp = ownerFetch["_refObjectName"];
dtrow2["Owner"] = strTemp.Replace(",", " ");
}
\\else { dtrow2["Owner"] = ""; }
dtrow2["Task-Est"] = items["Estimate"];
dtrow2["Task-ToDo"] = items["ToDo"];
dtrow2["Task-Spent"] = items["TimeSpent"];
dtrow2["ObjectType"] = "T";
dt.Rows.Add(dtrow2);
}
}
It seems like that should work. You may want to make sure you're including the TimeSpent field in your fetch before issuing the request.
taskRequest.Fetch = new List<string>() { "TimeSpent" };

Updating the google spreedsheet from MS SQL using Google Scripts

I'm trying to connect the MS SQL to a google spreadsheet using google app scripts. here is my app script code
function SQLdb() {
// Replace the variables in this block with real values.
// Read up to 1000 rows of data from the table and log them.
function readFromTable() {
var user = '{usename}';
var userPwd = '{password}';
var database = '{databasename}'
var connectionString = 'jdbc:sqlserver://server.database.windows.net:1433;databaseName='+database;
var conn = Jdbc.getConnection(connectionString , user, userPwd);
var start = new Date();
var stmt = conn.createStatement();
stmt.setMaxRows(1000);
var results = stmt.executeQuery('SELECT TOP 1000 * FROM dbo.dbo');
var numCols = results.getMetaData().getColumnCount();
while (results.next()) {
var rowString = '';
for (var col = 0; col < numCols; col++) {
rowString += results.getString(col + 1) + '\t';
}
Logger.log(rowString)
}
results.close();
stmt.close();
var end = new Date();
Logger.log('Time elapsed: %sms', end - start);
}
readFromTable();
}
Now when I look the log in Script Editor, I can see that this connection to the SQL database is working and the script is able to read all the table cell. But I couldn't able to get that data into the spreedsheet. I'm new to app scripts. So is there something that I'm missing here ?
Any help would be much appricated!
Here's how I do it. Change all the capitalised bits to the appropriate URL, database name, Google Spreadsheet ID, etc.
To this function pass the SQL query you want to execute on the MSSQL database and the name of the sheet within the Spreadsheet that you want to put the data into. This basically fills that named sheet with the query results including column names.
function getData(query, sheetName) {
//jdbc:sqlserver://localhost;user=MyUserName;password=*****;
var conn = Jdbc.getConnection("jdbc:sqlserver://URL;user=USERNAME;password=PASSWORD;databaseName=DBNAME");
var stmt = conn.createStatement();
stmt.setMaxRows(MAXROWS);
var rs = stmt.executeQuery(query);
Logger.log(rs);
var doc = SpreadsheetApp.openById("SPREADSHEETID");
var sheet = doc.getSheetByName(sheetName);
var results = [];
var cell = doc.getRange('a1');
var row = 0;
cols = rs.getMetaData();
colNames = [];
for (i = 1; i <= cols.getColumnCount(); i++ ) {
Logger.log(cols.getColumnName(i));
colNames.push(cols.getColumnName(i));
}
results.push(colNames);
var rowCount = 1;
while(rs.next()) {
curRow = rs.getMetaData();
rowData = [];
for (i = 1; i <= curRow.getColumnCount(); i++ ) {
rowData.push(rs.getString(i));
}
results.push(rowData);
rowCount++;
}
sheet.getRange(1, 1, MAXROWS, cols.getColumnCount()).clearContent();
sheet.getRange(1, 1, rowCount, cols.getColumnCount()).setValues(results);
Logger.log(results);
rs.close();
stmt.close();
conn.close();
}
Here is how i did it. I also made a JDBC connector tool for Mysql & MSSQL. You can adapt this tool from my GitHub Repo Here: Google Spreadsheet JDBC Connector
function readFromTable(queryType, queryDb, query, tab, startCell) {
// Replace the variables in this block with real values.
var address;
var user;
var userPwd ;
var dbUrl;
switch(queryType) {
case 'sqlserver':
address = '%YOUR SQL HOSTNAME%';
user = '%YOUR USE%';
userPwd = '%YOUR PW%';
dbUrl = 'jdbc:sqlserver://' + address + ':1433;databaseName=' + queryDb;
break;
case 'mysql':
address = '%YOUR MYSQL HOSTNAME%';
user = '%YOUR USER';
userPwd = '%YOUR PW%';
dbUrl = 'jdbc:mysql://'+address + '/' + queryDb;
break;
}
var conn = Jdbc.getConnection(dbUrl, user, userPwd);
var start = new Date();
var stmt = conn.createStatement();
var results = stmt.executeQuery(query);
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var sheetTab = sheet.getSheetByName(tab);
var cell = sheetTab.getRange(startCell);
var numCols = results.getMetaData().getColumnCount();
var numRows = sheetTab.getLastRow();
var headers ;
var row =0;
clearRange(tab,startCell,numRows, numCols);
for(var i = 1; i <= numCols; i++){
headers = results.getMetaData().getColumnName(i);
cell.offset(row, i-1).setValue(headers);
}
while (results.next()) {
var rowString = '';
for (var col = 0; col < numCols; col++) {
rowString += results.getString(col + 1) + '\t';
cell.offset(row +1, col).setValue(results.getString(col +1 ));
}
row++
Logger.log(rowString)
}
results.close();
stmt.close();
var end = new Date();
Logger.log('Time elapsed: %sms', end - start);
}
If you don't want to create your own solution, check out SeekWell. It allows you to connect to databases and write SQL queries directly in Sheets from a sidebar add-on. You can also schedule queries to automatically run daily, hourly or every five minutes.
Disclaimer: I made this.
Ok, I finally managed to make it work.
Some few tips: Script is executed at Google's server, so connection must be done over inetrnet, i.e. connect string should be something like "jdbc:sqlserver://172.217.29.206:7000;databaseName=XXXX" and make sure that ip/port mentioned at connect string, can reach you database from outside world. Open port at firewall, make IP forwarding at router and use dyndns or similar services if you do not have a valid domain etc. Sheet ID is the large id string that appeals at your google document's url.
