Try like this
var data = (from objData in receiptData
select new
{
ITEM_NAME=objData.ITEM_NAME,
UNIT_NAME=objData.UNIT_NAME,
PACK = objData.PACK,
RECIEVED_QTY =objData.RECIEVED_QTY.Value.ToString("0.00", System.Globalization.CultureInfo.InvariantCulture),
LPRATE = objData.LPRATE,
AMT = objData.LPRATE.Value * objData.RECIEVED_QTY.Value,
ESL = objData.ESL,
REMARKS = objData.REMARKS,
CHALLAN_NO=objData.CHALLAN_NO,
VEH_NO=objData.VEH_NO
});
You should refer Decimal.ToString Method for formatting decimals.
Math.Round(objData.RECIEVED_QTY.Value,2)

I have a BIRT report, which simply selects all the columns of a table. Every time a new column is added to the table I have to modify the report to visualize the new column. Is it possible somehow to show the result of a "select * from table" query in the report, so I shouldn't modify the report template anymore? The order of columns is not important.
Thank You.
This is not directly possible.
However, using the DE API, you can create and save a new rptdesign file based on the query, then in a second step execute that report.
The example at https://www.eclipse.org/birt/documentation/integrating/deapi.php only shows how to create layout items, but you can as well create Data Sources and Data Sets.
This is a bit tricky however, so unless you need this quite often, it is not worth the effort.
Here is an excerpt from a script I am using in a file sql2rptdesign.rptdesign to create a new report design. This should give you an idea:
importPackage(Packages.org.eclipse.birt.data.engine.api);
importPackage(Packages.org.eclipse.birt.data.engine.core);
importPackage(Packages.org.eclipse.birt.report.model.api);
importPackage(Packages.org.eclipse.birt.report.model.api.elements.structures);
importPackage(Packages.org.eclipse.birt.report.model.api.util);
importPackage(Packages.org.eclipse.birt.data.engine.api.querydefn);
var engine = reportContext.getReportRunnable().getReportEngine();
var myconfig = reportContext.getReportRunnable().getReportEngine().getConfig();
var designFactory = designHandle.getElementFactory();
// Ein neues DataSet anlegen
var de = DataEngine.newDataEngine( myconfig, null );
var dsrc = reportContext.getDesignHandle().findDataSource("lisa");
var dsHandle = designFactory.newOdaDataSet("Main", "org.eclipse.birt.report.data.oda.jdbc.JdbcSelectDataSet" );
dsHandle.setDataSource(dsrc.getName());
dsHandle.setQueryText(sql);
designHandle.getDataSets( ).add( dsHandle );
Then I add the output columns (I parsed the SQL statement beforehand to get the necessary information). I don't know if this is strictly needed.
var numColumns = 0;
for (var position=0; position<rows.length; position++) {
var row = rows[position];
var colName = row[0];
if (colName == "__Template") {
continue;
}
var colTyp = row[1];
var colWidth = row[2];
var resultCol = new OdaResultSetColumn();
resultCol.setColumnName(colName);
resultCol.setNativeName(colName);
resultCol.setDataType(colTyp);
resultCol.setPosition(position+1);
numColumns = position + 1;
dsHandle.getPropertyHandle(DataSetHandle.RESULT_SET_PROP).addItem(resultCol);
var resultHint = new ColumnHint();
resultHint.setProperty(ColumnHint.COLUMN_NAME_MEMBER, colName);
dsHandle.getPropertyHandle(DataSetHandle.COLUMN_HINTS_PROP).addItem(resultHint);
}
And then add a table, its column bindings, columns, detail rows and cell contents to the layout. This is a bit lenghty.
// Tabellarisches Layout
var elementFactory = designHandle.getElementFactory();
var body = designHandle.getBody();
var tab = elementFactory.newTableItem("Main", numColumns);
tab.setDataSet(dsHandle);
tab.pageBreakInterval = 9999;
for (var colNum=0; colNum<numColumns; colNum++) {
var r = rows[colNum];
var colName = r[0];
var colNameSlashes = addSlashes(colName);
var colType = r[1];
var width = r[2];
var pattern = r[3];
var align = r[4];
// Binding
var colBinding = StructureFactory.createComputedColumn( );
colBinding.setName(colName);
colBinding.setExpression( 'dataSetRow[' + colNameSlashes + ']');
colBinding.setDataType(colType);
tab.addColumnBinding(colBinding, true);
// Überschrift
var textdata = elementFactory.newTextData(null);
textdata.setContentType("plain");
textdata.setValueExpr(colNameSlashes);
textdata.setStringProperty("whiteSpace", "normal");
tab.getLayoutModel().getCell(1,colNum+1).getContent().add(textdata);
// Wert
var textdata = elementFactory.newTextData(null);
textdata.setContentType("plain");
textdata.setHasExpression(true);
textdata.setStringProperty("whiteSpace", "normal");
var expr = 'row[' + colNameSlashes + ']';
textdata.setValueExpr(expr);
tab.getLayoutModel().getCell(2,colNum+1).getContent().add(textdata);
// Spaltenbreite und Ausrichtung
var columnHandle = tab.getColumns().get(colNum); // 0-basiert?
if (width) {
columnHandle.setProperty("width", StringUtil.parse(width));
}
}
body.add(tab, 0);
And finally save the new file:
designHandle.saveAs(designFilename);
However, this doesn't use a template as you would like to do.
I have a problem with charsets.
I parsed a csv file in google-app-engine and I'm posting to an uiapp table.
But I checked special characters like áéíóú and those are not well displayed (?square symbol).
When I was setting up my code I played writing the string imported to a google docs document and it worked the same.
some advice please?
I search for:
a global charset definition to the code. or
string var transformation that makes the chars appear like I want to. (avoiding html &number definitions.
Is this related to the blob object?
The thing is important i come from spain and we need such characters.
app that get's a csv ';' delimited file and shows it's content
I post all my code, it's barely as the tutorial that is given.
function arreglaUrl(cadena){
var texto = cadena[cadena.length - 2]
if (texto == ''){
cadena[cadena.length - 2] = 'Sin enlace';
}
else{
cadena[cadena.length - 2] = '<center>Link.</center>' ;
};
}
function parsedCSV(){
var listaArchivos = DocsList.getFolderById('XXXXX').getFiles()
for (var i = 0; i < listaArchivos.length; i++) {
if (listaArchivos[i].getName() == 'baul.csv'){
var origen = listaArchivos[i];
};
}
var texto = origen.getContentAsString();
var arra = Utilities.parseCsv(texto,";");
return(arra);
}
function doGet() {
var datos = parsedCSV()
var baul = Charts.newDataTable()
for (i = 0; i < datos[0].length; i++){
baul.addColumn(Charts.ColumnType.STRING, datos[0][i])
}
for (i = 1; i < datos.length; i++){
arreglaUrl(datos[i]) // this only makes some html i need to post some links
baul.addRow(datos[i])
}
baul.build();
var sectorFilter = Charts.newCategoryFilter()
.setFilterColumnLabel("sector")
.build();
var tipoFilter = Charts.newCategoryFilter()
.setFilterColumnLabel("tipo")
.build();
var searchFilter = Charts.newStringFilter()
.setFilterColumnLabel("Titulo")
.build();
var searchDesc = Charts.newStringFilter()
.setFilterColumnLabel("descripcion")
.build();
var tableChart = Charts.newTableChart().setOption('allowHtml', true).setDimensions(0,0)
.build();
var dashboard = Charts.newDashboardPanel()
.setDataTable(baul)
.bind([sectorFilter, tipoFilter, searchFilter, searchDesc], [tableChart])
.build();
var uiApp = UiApp.createApplication().setTitle('Baul de Recursos');
var anchoTotal = '100%';
dashboard.add(uiApp.createVerticalPanel()
.add(uiApp.createHorizontalPanel()
.add(sectorFilter)
.add(tipoFilter)
.setSpacing(15)
)
.add(uiApp.createHorizontalPanel()
.add(searchFilter)
.add(searchDesc)
.setSpacing(15)
)
.add(uiApp.createHorizontalPanel()
.add(tableChart).setBorderWidth(1).setHorizontalAlignment(UiApp.HorizontalAlignment.CENTER).setWidth(anchoTotal)
)
);
uiApp.add(dashboard);
return uiApp;
}
I found it, we need to get the content of the file first with a Blob object.
This function is the one I use to parse some csv info into an array:
function parsedCSV(){
//searching the file. This gets only one file in var origen
var listaArchivos = DocsList.getFolderById('XXXXXXX').getFiles()
for (var i = 0; i < listaArchivos.length; i++) {
if (listaArchivos[i].getName() == 'baul.csv'){
var origen = listaArchivos[i];
};
}
// HERE IS THE GOOD DEFINITION OF CHAR:
var texto2= origen.getBlob().getDataAsString('ISO-8859-1');
// I put all the corrected text in an array
var arra = Utilities.parseCsv(texto2,";");
return(arra);
}
This is the solved thing: https://script.google.com/macros/s/AKfycbyHa-bLWBHBr3qifbvzxecqGgGUYX8mhyo-TKoyfGvy/exec
The trick:
var textVariableName = fileObjectVariableName.getBlob().getDataAsString('ISO-8859-1');
i'm very new to LINQ? please help me
How would you translate the following generic Lambda function into a lambda expression :
objects.Where(objects=>values.Contains(objects.DistrictId) );
I'm trying to create a full lambda expression without any or direct call. Something like :
var innerItem = Expression.Parameter(typeof(Objects), "objects");
var innerProperty = Expression.Property(innerItem, "ID");
var innerMethodExpression = Expression.Call(innerProperty,null);
var innerLambda = Expression.Lambda<Func<Objects, bool>>(innerMethodExpression, innerItem);
var outerItem = Expression.Parameter(typeof(int[]), "item");
var containsMethod = typeof(string).GetMethod("Contains", new[] { typeof(int) });
var containsMethodExpression = Expression.Call(innerMethodExpression, containsMethod, innerLambda);
var outerLambda = Expression.Lambda<Func<Objects, bool>>(containsMethodExpression, outerItem);
collection = collection.AsQueryable<Objects>().Where(outerLambda);
But i can't understand what is wrong
In your example,
The Lambda function is
objects.Where(objects=>values.Contains(objects.DistrictId) );
so your lambda expression should be
Expression<Func<Objects, int>> ObjectsExp = objects=>values.Contains(objects.DistrictId);
Assume DistrictId is integer type for your out Result.
I have a stored procedure as
pr___GetArchiveData
Select * from TABLE1
SELECT * FROM TABLE2
SELECT * FROM TABLE 3
I want to get this result set into a dataset. Or access the values of three select queries!!
I have a DBML file in which when i drag and drop the stored procedure generates a code as follows:-
global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.pr___GetArchiveData")]
public ISingleResult<pr___GetArchiveDataResult> pr___GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(DbType="UniqueIdentifier")] System.Nullable<System.Guid> projectID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), projectID);
return ((ISingleResult<pr__Project_pr___GetArchiveData>)(result.ReturnValue));
}
In the code MVC3 Architecture + LINQ i have written a code to get the result set as follows :-
using (HBDataContext hb = new HBDataContext())
{
System.Data.DataSet ds = new System.Data.DataSet();
String connString = connString;
var conn = new System.Data.SqlClient.SqlConnection(connString);
var cmd = conn.CreateCommand();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "pr__GetArchiveData";
cmd.Connection.Open();
var mReader = cmd.ExecuteReader(System.Data.CommandBehavior.SequentialAccess);
//var reader = cmd.ExecuteReader();
//using (System.Data.SqlClient.SqlDataReader mReader = cmd.ExecuteReader())
//{
// while (mReader.Read())
//{
// mReader.Read();
var tbl1 = hb.Translate<tbl1 >(mReader).ToList();
// mReader = cmd.ExecuteReader();
mReader.NextResult();
var tbl2 = hb.Translate<tbl2 >(mReader).ToList();
mReader.NextResult();
var tbl3 = hb.Translate<tbl3>(mReader).ToList();
// }
// }
}
But while running it throws error as -
"Invalid attempt to call NextResult when reader is closed."
I am not sure where i am wrong!!
I have tried using it as while
(mReader.Read())
Kindly suggest!!!!
The code gen for ISingleResult won't provide multiple result sets
Try adding your own IMultipleResults wrapper - see the tutorial in http://blogs.msdn.com/b/dditweb/archive/2008/05/06/linq-to-sql-and-multiple-result-sets-in-stored-procedures.aspx
In .dbml file for the stored procedure the code will be like
[global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.pr__Home_GetArchiveData")]
public ISingleResult<pr__Home_GetArchiveData> pr__Home_GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(Name="AlbumID", DbType="UniqueIdentifier")] System.Nullable<System.Guid> albumID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), albumID);
return ((ISingleResult<pr__Album_GetAlbumsFilesResult>)(result.ReturnValue));
}
Replace it with IMultipleResult as below `
[global::System.Data.Linq.Mapping.FunctionAttribute(Name = "dbo.pr__Home_GetArchiveData")]
[ResultType(typeof(tbl1))]
[ResultType(typeof(tbl2))]
[ResultType(typeof(tbl3))]
[ResultType(typeof(tbl4))]
public IMultipleResults pr__Home_GetArchiveData([global::System.Data.Linq.Mapping.ParameterAttribute(Name = "HOMEID", DbType = "UniqueIdentifier")] System.Nullable hOMEID)
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), hOMEID);
return ((IMultipleResults)result.ReturnValue);
}
in the code .
using (HBDataContext hb = new HBDataContext())
{
using (System.Data.Linq.IMultipleResults _results = hb.pr__Home_GetArchiveData(model.HomeID))
{
List<tbl1> _tbl1= _results.GetResult<tbl1>().ToList();
List<tbl2> _tbl2= _results.GetResult<tbl2>().ToList();
List<tbl3> _tbl3= _results.GetResult<tbl3>().ToList();
List<tbl4> _tbl4= _results.GetResult<tbl4>().ToList();}}
You will get the values of the Select queries from theStoredProcedure ...
How can I update a record against specific id in LINQ to SQL?
LINQ is a query tool (Q = Query) - so there is no magic LINQ way to update just the single row, except through the (object-oriented) data-context (in the case of LINQ-to-SQL). To update data, you need to fetch it out, update the record, and submit the changes:
using(var ctx = new FooContext()) {
var obj = ctx.Bars.Single(x=>x.Id == id);
obj.SomeProp = 123;
ctx.SubmitChanges();
}
Or write an SP that does the same in TSQL, and expose the SP through the data-context:
using(var ctx = new FooContext()) {
ctx.UpdateBar(id, 123);
}
In the absence of more detailed info:
using(var dbContext = new dbDataContext())
{
var data = dbContext.SomeTable.SingleOrDefault(row => row.id == requiredId);
if(data != null)
{
data.SomeField = newValue;
}
dbContext.SubmitChanges();
}
AdventureWorksDataContext db = new AdventureWorksDataContext();
db.Log = Console.Out;
// Get hte first customer record
Customer c = from cust in db.Customers select cust where id = 5;
Console.WriteLine(c.CustomerType);
c.CustomerType = 'I';
db.SubmitChanges(); // Save the changes away
DataClassesDataContext dc = new DataClassesDataContext();
FamilyDetail fd = dc.FamilyDetails.Single(p => p.UserId == 1);
fd.FatherName=txtFatherName.Text;
fd.FatherMobile=txtMobile.Text;
fd.FatherOccupation=txtFatherOccu.Text;
fd.MotherName=txtMotherName.Text;
fd.MotherOccupation=txtMotherOccu.Text;
fd.Phone=txtPhoneNo.Text;
fd.Address=txtAddress.Text;
fd.GuardianName=txtGardianName.Text;
dc.SubmitChanges();
I found a workaround a week ago. You can use direct commands with "ExecuteCommand":
MDataContext dc = new MDataContext();
var flag = (from f in dc.Flags
where f.Code == Code
select f).First();
_refresh = Convert.ToBoolean(flagRefresh.Value);
if (_refresh)
{
dc.ExecuteCommand("update Flags set value = 0 where code = {0}", Code);
}
In the ExecuteCommand statement, you can send the query directly, with the value for the specific record you want to update.
value = 0 --> 0 is the new value for the record;
code = {0} --> is the field where you will send the filter value;
Code --> is the new value for the field;
I hope this reference helps.
