Currently, I'm using Conversion Studio to bring in a CSV file and store the contents in an AX table. This part is working. I have a block defined and the fields are correctly mapped.
The CSV file contains several comments columns, such as Comments-1, Comments-2, etc. There are a fixed number of these. The public comments are labeled as Comments-1...5, and the private comments are labeled as Private-Comment-1...5.
The desired result would be to bring the data into the AX table (as is currently working) and either concatenate the comment fields or store them as separate comments into the DocuRef table as internal or external notes.
Would it not require just setting up a new block in the Conversion Studio project that I already have setup? Can you point me to a resource that maybe shows a similar procedure or how to do this?
Thanks in advance!
After chasing the rabbit down the deepest of rabbit holes, I discovered that the easiest way to do this is like so:
Override the onEntityCommit method of your Document Handler (that extends AppDataDocumentHandler), like so:
AppEntityAction onEntityCommit(AppDocumentBlock documentBlock, AppBlock fromBlock, AppEntity toEntity)
{
AppEntityAction ret;
int64 recId; // Should point to the record currently being imported into CMCTRS
;
ret = super(documentBlock, fromBlock, toEntity);
recId = toEntity.getRecord().recId;
// Do whatever you need to do with the recId now
return ret;
}
Here is my method to insert the notes, in case you need that too:
private static boolean insertNote(RefTableId _tableId, int64 _docuRefId, str _note, str _name, boolean _isPublic)
{
DocuRef docuRef;
boolean insertResult = false;
;
if (_docuRefId)
{
try
{
docuRef.clear();
ttsbegin;
docuRef.RefCompanyId = curext();
docuRef.RefTableId = _tableId;
docuRef.RefRecId = _docuRefId;
docuRef.TypeId = 'Note';
docuRef.Name = _name;
docuRef.Notes = _note;
docuRef.Restriction = (_isPublic) ? DocuRestriction::External : DocuRestriction::Internal;
docuRef.insert();
ttscommit;
insertResult = true;
}
catch
{
ttsabort;
error("Could not insert " + ((_isPublic) ? "public" : "private") + " comment:\n\n\t\"" + _note + "\"");
}
}
return insertResult;
}

I have been trying to load an SQL database into a datatable in C++, however; it doesn't seem to want to work. The connection is working though, as DataReader works. Here is my code
void importDatabase() {
SqlConnection con;
SqlDataAdapter^ da;
SqlCommand cmd;
DataTable^ dt;
int count = 1;
try {
con.ConnectionString = "Data Source=MYNAME\\SQLEXPRESS;Initial Catalog=VinylRecords;Integrated Security=True";
cmd.CommandText = "SELECT * FROM Records";
cmd.Connection = %con;
con.Open();
da = gcnew SqlDataAdapter(%cmd);
dt = gcnew DataTable("Records");
Console::Write(da->ToString());
da->Fill(dt);
for (int i = 0; i < dt->Rows->Count - 1; i++) {
String^ value_string;
value_string = dt->Rows[i]->ToString();
Console::WriteLine(dt->Rows[i]->ToString());
count++;
}
cout << "There are " << count << " many records";
}
catch (Exception^ ex) {
Console::WriteLine(ex->ToString());
}
}
Please note, that I slightly altered the source name to post here, but only the first part.
What is wrong with my code?
So, the problem is here:
dt->Rows[i]->ToString()
Rows[i] is a Row object. And the Row class's ToString() method always prints out the fully qualified typename, which is what you are seeing. So this is technically working just fine. What you will need to do to get something useful is: you will need to access a specific column in that row and get it's value, then output that.
Something along the lines of:
foreach (DataRow dr in dt.Rows)
{
Console.Write(dr.Field<int>("ColumnOne"));
Console.Write(" | ");
Console.WriteLine(dr.Field<string>("ColumnTwo"));
}
I am not entirely sure on the syntax for accessing a specific cell inside of a DataTable when using C++\CLI. So I have provided the C# equivalent to explain why it is you were getting output of managed type names (e.g. "System.Data.DataRow") instead of the info inside of the Row's columns.
Also, I noticed you tagged this question with "mysql", but you are using the ADO.NET System.Data.SqlClient namespace. The SqlDataReader and SqlDataAdapter classes only work with TSQL (Microsoft's SQL Server databases) If you are actually connecting to a mysql database you will want to use the System.Data.OdbcDataAdapter class. You can read a little more here: https://msdn.microsoft.com/en-us/library/ms254931.aspx
We have a named query like this:
UPDATE Foo f SET f.x = 0 WHERE f.x = :invoiceId
Foo in this case is an entity with a superclass, using the table-per-class inheritance strategy.
The SQL that EclipseLink generates is:
UPDATE foo_subclass SET x = ?
WHERE EXISTS(SELECT t0.id
FROM foo_superclass t0, foo_subclass t1
WHERE ((t1.x = ?) AND ((t1.id = t0.id) AND (t0.DTYPE = ?)))
(The ? slots are correctly filled in.)
On Informix 11.70, we get an error that the subquery cannot access the table being changed.
Here is the documentation that I was able to find on subquery restrictions on Informix: http://publib.boulder.ibm.com/infocenter/idshelp/v115/index.jsp?topic=%2Fcom.ibm.sqls.doc%2Fids_sqs_2005.htm
Other databases also feature restrictions on subqueries like this, so although this is manifesting as an Informix issue, I'm sure that if we ran this against, say, MySQL, we would get a similar error.
How can I get EclipseLink to honor these restrictions? Is there a better query I should be using?
Instead of:
UPDATE foo_subclass SET x = ?
WHERE EXISTS(SELECT t0.id
FROM foo_superclass t0, foo_subclass t1
WHERE ((t1.x = ?) AND ((t1.id = t0.id) AND (t0.DTYPE = ?)))
do this:
UPDATE
foo_subclass SET x = ?
WHERE
foo_subclass.x = ? AND
EXISTS(SELECT t0.id
FROM foo_superclass t0
WHERE ((foo_subclass.id = t0.id) AND (t0.DTYPE = ?))
Note that on 11.50 you cannot use alias for foo_subclass. It's allowed in 11.70.
I'm assuming "id" are primary keys (or at least unique identifiers).
Found the answer. Looks like EclipseLink had to handle this case for MySQL, which also has similar issues.
The answer is that in your InformixPlatform subclass, you need to override the following methods to solve this problem:
supportsLocalTemporaryTables(): this needs to return true
shouldAlwaysUseTempStorageForModifyAll(): this needs to return true
dontBindUpdateAllQueryUsingTempTables needs to return true
getCreateTempTableSqlPrefix(): this needs to return CREATE TEMP TABLE
getCreateTempTableSqlSuffix(): this needs to return WITH NO LOG
isInformixOuterJoin(): needs to return false
getTempTableForTable(DatabaseTable): this needs to do this:
return new DatabaseTable("TL_" + table.getName(), "" /* no table qualifier */, table.shouldUseDelimiters(), this.getStartDelimiter(), this.getEndDelimiter());
In addition, you need to override the following methods as well for proper InformixPlatform behavior:
appendBoolean(Boolean, Writer): the stock Informix platform does not write out boolean literals properly. Yours needs to do this:
if (Boolean.TRUE.equals(booleanValue)) {
writer.write("'t'");
} else {
writer.write("'f'");
}
You need to override writeUpdateOriginalFromTempTableSql so that it contains the same code as the H2Platform's override does:
#Override
public void writeUpdateOriginalFromTempTableSql(final Writer writer, final DatabaseTable table, final Collection pkFields, final Collection assignedFields) throws IOException {
writer.write("UPDATE ");
final String tableName = table.getQualifiedNameDelimited(this);
writer.write(tableName);
writer.write(" SET ");
final int size = assignedFields.size();
if (size > 1) {
writer.write("(");
}
writeFieldsList(writer, assignedFields, this);
if (size > 1) {
writer.write(")");
}
writer.write(" = (SELECT ");
writeFieldsList(writer, assignedFields, this);
writer.write(" FROM ");
final String tempTableName = this.getTempTableForTable(table).getQualifiedNameDelimited(this);
writer.write(tempTableName);
writeAutoJoinWhereClause(writer, null, tableName, pkFields, this);
writer.write(") WHERE EXISTS(SELECT ");
writer.write(((DatabaseField)pkFields.iterator().next()).getNameDelimited(this));
writer.write(" FROM ");
writer.write(tempTableName);
writeAutoJoinWhereClause(writer, null, tableName, pkFields, this);
writer.write(")");
}
Lastly, your constructor needs to call this.setShouldBindLiterals(false).
With these changes, it seems that Informix is happy.
My question is: How can I order a DBGrid by a calculated field. I am using the C++Builder Starter Editon and do not have a ClientDataSet available in this version to create an Index on the field and order by the index of a column.So this is not an option. (Read this in many threads) I am using an TIBDataSet (ibds below) and I am filtering the data. Works fine....for the DB-columns, not for the calculated ones... Any ideas of how I might get around this problem?
void __fastcall TForm1::DBGrid3TitleClick(TColumn *Column)
{
static cIdx = 0;
static String oby = "ASC";
TBookmark CurrentPosition;
TIBDataSet *ibds = IBDS_accountsDist;
CurrentPosition = ibds->GetBookmark();
if (cIdx != Column->Index) {
oby = "ASC"; // ANOTHER column choosen
} else if (oby == "ASC") {
oby = "DESC";
} else oby = "ASC";
cIdx = Column->Index;
ibds->Filtered = false;
switch (Column->Index){
case 0: ibds->Filter = "ORDER BY SumAj "+oby; break; // SumAj is a calculated field => Does not work
case 1: ibds->Filter = "ORDER BY CSAL_ACCOUNTNAME "+ oby; break; // DB-field WORKS FINE
}
ibds->Filtered = true;
ibds->GotoBookmark(CurrentPosition);
}
You cannot do it. TIBDataSet is a representation of the underlying database. Basically it fetches the records in the order defined in the SQL.
The easiest way is to use TDBClientDataset but it is not included in Starter version of c++ Builder. You can explore other ways, for example pre-loading all records in a std::list and then use the order function to order the records. Finally you can show them using a simple TGrid o TStringGrid.
In any case, I recommend to upgrade C++Builder since TClientDataSet is one of the main pieces in most of data projects, specially when you need to create medium-large projects.
Mixing database specific components like TIBDataSet with the user interface penalizes the scalability and maintenance of the project.
I'm generating a reporting services report from an ASP.NET (MVC) based application but am having problems setting the parameters for the report.
I believe the issue has only occurred since we upgraded SQL Server from 2005 to 2008 R2 (and Reporting Services along with it).
The original error encountered was from calling rsExec.Render:
Procedure or function 'pCommunication_ReturnRegistrationLetterDetails'
expects parameter '#guid', which was not supplied.
Debugging the code I noticed that rsExec.SetExecutionParameters is returning the following response:
Cannot call 'NameOfApp.SQLRSExec.ReportExecutionService.SetExecutionParameters(NameOfApp.SQLRSExec.ParameterValue[],
string)' because it is a web method.
Here is the function in it's entirety:
public static bool ProduceReportToFile(string reportname, string filename, string[,] reportparams,
string fileformat)
{
bool successful = false;
SQLRS.ReportingService2005 rs = new SQLRS.ReportingService2005();
SQLRSExec.ReportExecutionService rsExec = new NameOfApp.SQLRSExec.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
// Prepare Render arguments
string historyID = null;
string deviceInfo = null;
// Prepare format - available options are "PDF","Word","CSV","TIFF","XML","EXCEL"
string format = fileformat;
Byte[] results;
string encoding = String.Empty;
string mimeType = String.Empty;
string extension = String.Empty;
SQLRSExec.Warning[] warnings = null;
string[] streamIDs = null;
// Define variables needed for GetParameters() method
// Get the report name
string _reportName = reportname;
string _historyID = null;
bool _forRendering = false;
SQLRS.ParameterValue[] _values = null;
SQLRS.DataSourceCredentials[] _credentials = null;
SQLRS.ReportParameter[] _parameters = null;
// Get if any parameters needed.
_parameters = rs.GetReportParameters(_reportName, _historyID,
_forRendering, _values, _credentials);
// Load the selected report.
SQLRSExec.ExecutionInfo ei =
rsExec.LoadReport(_reportName, historyID);
// Prepare report parameter.
// Set the parameters for the report needed.
SQLRSExec.ParameterValue[] parameters =
new SQLRSExec.ParameterValue[1];
// Place to include the parameter.
if (_parameters.Length > 0)
{
for (int i = 0; i < _parameters.Length; i++)
{
parameters[i] = new SQLRSExec.ParameterValue();
parameters[i].Label = reportparams[i,0];
parameters[i].Name = reportparams[i, 0];
parameters[i].Value = reportparams[i, 1];
}
}
rsExec.SetExecutionParameters(parameters, "en-us");
results = rsExec.Render(format, deviceInfo,
out extension, out encoding,
out mimeType, out warnings, out streamIDs);
// Create a file stream and write the report to it
using (FileStream stream = System.IO.File.OpenWrite(filename))
{
stream.Write(results, 0, results.Length);
}
successful = true;
return successful;
}
Any ideas why I'm now unable to set parameters? The report generation works without issue if parameters aren't required.
Looks like it may have been an issue with how reporting services passes parameters through to the stored procedure providing the data. A string guid was being passed through to the report and the stored procedure expected a varchar guid. I suspect reporting services may have been noticing the string followed the guid format pattern and so passed it through as a uniqueidentifier to the stored procedure.
I changed the data source for the report from "stored procedure" to "text" and set the SQL as "EXEC pMyStoredOProcName #guid".
Please note the guid being passed in as a string to the stored procedure is probably not best practice... I was simply debugging an issue with another developers code.
Parameter _reportName cannot be null or empty. The [CLASSNAME].[METHODNAME]() reflection API could not create and return the SrsReportNameAttribute object
In this specific case it looks like an earlier full compile did not finish.
If you encounter this problem I would suggest that you first compile the class mentioned in the error message and see if this solves the problem.
go to AOT (get Ctrl+D)
in classes find CLASSNAME
3.compile it (F7)
I need to get the primary key for a row and then insert it into one of the other columns in a string.
So I've tried to do it something like this:
newsObj = new news();
newsObj.name = "test"
newsObj.Save();
newsObj.url = String.Format("blah.aspx?p={0}",newsObj.col_id);
newsObj.Save();
But it doesn't treat it as the same data object so newsObj.col_id always comes back as a zero. Is there another way of doing this? I tried this on another page and to get it to work I had to set newsObj.SetIsLoaded(true);
This is the actual block of code:
page p;
if (pageId > 0)
p = new page(ps => ps.page_id == pageId);
else
p = new page();
if (publish)
p.page_published = 1;
if (User.IsInRole("administrator"))
p.page_approved = 1;
p.page_section = staticParent.page_section;
p.page_name = PageName.Text;
p.page_parent = parentPageId;
p.page_last_modified_date = DateTime.Now;
p.page_last_modified_by = (Guid)Membership.GetUser().ProviderUserKey;
p.Add();
string urlString = String.Empty;
if (parentPageId > 0)
{
urlString = Regex.Replace(staticParent.page_url, "(.aspx).*$", "$1"); // We just want the static page URL (blah.aspx)
p.page_url = String.Format("{0}?p={1}", urlString, p.page_id);
}
p.Save();
If I hover the p.Save(); I can see the correct values in the object but the DB is never updated and there is no exception.
Thanks!
I faced the same problem with that :
po oPo = new po();
oPo.name ="test";
oPo.save(); //till now it works.
oPo.name = "test2";
oPo.save(); //not really working, it's not saving the data since isLoaded is set to false
and the columns are not considered dirty.
it's a bug in the ActiveRecord.tt for version 3.0.0.3.
In the method public void Add(IDataProvider provider)
immediately after SetIsNew(false);
there should be : SetIsLoaded(true);
the reason why the save is not working the second time is because the object can't get dirty if it is not loaded. By adding the SetIsLoaded(true) in the ActiveRecord.tt, when you are going to do run custom tool, it's gonna regenerate the .cs perfectly.
