Currently I'm working on legacy application, that uses crystal report engine. I have to get value of database fields programmatically. As I've assumed, I need proper event for getting next code to work:
Report.Database.Tables(1).Fields(1).Value
But the value is always empty in DownloadStarted/Finished event handlers. What I'm doing wrong and is it at least possible?
I think that if you want to get value of your table fields in program the best way is that you get the field name from report and then connect to your table directly and use report field names as the table columns name
i do it in c# i hope it can help you in vb6 too:
string name = report2.Database.Tables[1].Fields[1].Name;
string[] names = name.Split('.');
and then add your database to your program and use names like this:
DataTable dt = new DataTable();
string[] value = dt.Columns[names[1]];
if you just need your tables values, you can use my last answer, but if you need value of database fields in crystal report, i mean something like formula field ,this code can help you:
CRAXDRT.FormulaFieldDefinitions definitions = report2.FormulaFields;
string formulaText = "IF " + report2.Database.Tables[1].Fields[3].Name
+ " > 10 THEN" + report2.Database.Tables[1].Fields[2].Name;
definitions.Add("Test", formulaText);
report2.Sections[1].AddFieldObject(definitions[1], 0, 0);

I would like to add a dynamic parameter in addition to parameters from Maximo inside SQL query.
Something like that :
select *
from workorder a
where params["where"] or a.parent = :Param
with params["where"] with wonum='1234' and :Param = '1234'
Is it possible with Birt to get wonum value and put it also to :Param ?
Or maybe another way ?
Thanks
open is like that (query is more complicated so I simplify it):
maximoDataSet = MXReportDataSetProvider.create(this.getDataSource().getName(), this.getName());
maximoDataSet.open();
var sqlText = new String();
sqlText = "select column1, column2 as woParent, etc... from workorder where " + params["where"] + " or woParent=:param";
maximoDataSet.setQuery(sqlText);
beforeopen is like that(just to see the query) :
importPackage( Packages.java.io );
out = new PrintWriter( new FileWriter( "c:/birteaump.log", true ) );
out.println( "\nMy Query: " + this.queryText);
out.close();
I had some code to manipulate :param to replace it with wonum but this.queryText is null.
I'm a newbie to birt report maybe I have to think differently to solve my problem.
Thanks
I used Birt 3.7.1. I saw in a video that we can add a query in a dataset's dialog box. But with my report I only have "scripted data set" when I use the "new data set" button.
Is it possible that my query is null in "beforeopen" is in relation with that ?
If I create another sort of datasource, I will have acces to another sort of dataset ?
thanks
ok I solved my problem.
I created a JDBC data source and I have access to a new sort of data set.
I can put my query in this data set and I have access to "beforeopen" and my query is not null.
Thanks
For table cmdb_rel_ci, I want to retrieve unique parent.sys_class_name with count for "type=In Rack::Rack contains". I am doing practice in out of the box instance.
At table level URL is as below:
URL
I want to retrieve result from above URL with my below script.
var count = new GlideAggregate('cmdb_rel_ci');
count.addQuery('type','e76b8c7b0a0a0aa70082c9f7c2f9dc64');// sys_id of type In Rack::Rack contains e76b8c7b0a0a0aa70082c9f7c2f9dc64
count.addAggregate('COUNT', 'parent.sys_class_name');
count.query();
while(count.next()){
var parentClassName = count.parent.sys_class_name.toString();
var parentClassNameCount = count.getAggregate('COUNT','parent.sys_class_name');
gs.log(parentClassName + " : " + parentClassNameCount );
}
The issue is I am getting parentClassName empty.
Try this instead:
var parentClassName = count.getValue("parent.sys_class_name")
Since it's a GlideAggregate query (instead of GlideRecord), the query being issued isn't returning all of the fields on the target table. With GlideRecord, dot-walking through a reference field (e.g. parent.sys_class_name) automatically resolves that referenced record to provide access to its field values. This is made possible by the fact that the driving/original query brought back the value of the parent field. This is not happening with GlideAggregate. The query in this case basically looks like:
SELECT cmdb1.`sys_class_name` AS `parent_sys_class_name`, count(*)
FROM (cmdb_rel_ci cmdb_rel_ci0 LEFT JOIN cmdb cmdb1 ON cmdb_rel_ci0.`parent` = cmdb1.`sys_id` )
WHERE cmdb_rel_ci0.`type` = 'e76b8c7b0a0a0aa70082c9f7c2f9dc64'
GROUP BY cmdb1.`sys_class_name`
ORDER BY cmdb1.`sys_class_name`
So, you actually have access specifically to that dot-walked sys_class_name that's being grouped, but not through the dot-walk. The call to getValue("parent.sys_class_name") is expectedly resolved to the returned column aliased as parent_sys_class_name.
That being said, what you're doing probably should also work, based on user expectations, so you've not done anything incorrect here.
In my Yii application, I have a model that represents siteconfig table and have four columns:
integer config_id,
string key,
string value,
string update_time.
I created a model using Gii (to ensure that I will not make any mistakes). I don't publish entire code here, cause this is 100% unmodified by me, standard model code generated by Gii. Since my problem is related to search, I only publish important part of generated code (the search() method):
public function search()
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('config_id',$this->config_id);
$criteria->compare('key',$this->key,true);
$criteria->compare('value',$this->value,true);
$criteria->compare('update_time',$this->update_time,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
I'm trying to use generated model in normal Yii ActiveRecord search like that:
$etona = new SiteConfigurationRecord();
$crit = new CDbCriteria();
$crit->select = "value";
$crit->condition = "key=:key";
$crit->params = array(":key"=>"sitename");
$etona = $etona->find($crit);
But, instead of getting expected search results, a strange (for me) error occurs:
CDbCommand failed to execute the SQL statement: SQLSTATE[42000]:
Syntax error or access violation: 1064 You have an error in your SQL
syntax; check the manual that corresponds to your MySQL server version
for the right syntax to use near 'key='sitename' LIMIT 1' at line 1.
The SQL statement executed was: SELECT value FROM siteconfig t
WHERE key=:key LIMIT 1
Where did I go wrong?
You used key for column name, which is a reserved word in MySQL. Yii uses table alias in queries, but does not take any special care in case of reserverd word used as columns names. So, you have to take care of this by yourself.
For example:
$etona = new SiteConfigurationRecord();
$crit = new CDbCriteria();
$crit->select = "value";
$crit->condition = "t.key=:key"; // 't' is default alias
$crit->params = array(":key"=>"sitename");
$etona = $etona->find($crit);
This should solve your problem.
As #Dmitry explained, SQL doesn't allow you to use the column name key. The Yii call in the code in your answer works because Yii performs parameter binding automatically, using names other than reserved words for the parameters. And it also uses fully-qualified column names (prefixes all column name references with <tablename>., regardless of what invalid column name (reserved words) you pass the findByAttributes method.
now it works.. ^^
i just use this code...
$etona = SiteConfigurationRecord::model()->findByAttributes(array('key'=>'sitename'));
maybe i need to study activerecord more somehow...
but still i don't know why the code above doesn't work
I created a strongly-typed dataset in the dataset designer. The DataSet has a Table called FocusOffsetsTable and that table has four colums; SerialNumber, Filter, Wheel and Offset. I use the ReadXml() method of the DataSet class to load the strongly typed data from the xml file into the dataset. That seems to be working just fine.
I am trying to use a LINQ expression to try to get a Single row from this table but I can't seem to get the syntax correct. I want to use the Single() or SingleOrDefault() method to get just one row of data at a time but I am not sure how.
I have tried this FocusOffsets.FocusOffsetsTableRow x = FocusOffsetData.FocusOffsetsTable. but the Single() method is not available here. I also tried this...
FocusOffsets.FocusOffsetsTableRow x = (from offset in FocusOffsetData.FocusOffsetsTable
where offset.SerialNumber == mydevice.SerialNumber
where offset.Wheel == WheelID
where offset.Filter == FilterNum
select offset).Single();
but the Single method is not available here either.
I have done this before with tables in a SQL database before but this is my first time using a dataset from the dataset designer.
Have you added a using statement for System.Linq and included a reference to System.Data.DataSetExtensions. I think (but can't confirm since I'm on my Mac), that you ought to be able to do:
var x = FocusOffsetData.FocusOffsetsTable
.AsEnumerable()
.SingleOrDefault( o => o.SerialNumber == mydevice.SerialNumber
&& o.Wheel = WheelID
&& o.Filter = FilterNum );
ds = (DataSet)Session["Details"];
DataTable dt = ds.Tables[0];
DataTable temp = dt.Clone();
dt.Rows.Add(ds.Tables[0].Select("ID =" + ID));
Error message:Unable to cast object of type 'System.Data.DataRow' to type 'System.IConvertible'.Couldn't store <System.Data.DataRow> in Date Column. Expected type is DateTime.
can anybody help me please.
ImportRow is designed for this kind of scenarios only, so check it out. I have used it manytimes for such requirements.
I think it's a fault in the overloads. If you were working in VB, I would tell you to use the row:=ds.Tables[0].Select("ID =" + ID) notation in the parameters, but I don't think C# has this.
I think the Add function assumes you're feeding it the array of values for the new row, instead of a datarow itself.
