I'm a beginner with pentaho data integration and I want to split a string with the following form : FIRSTNAME LASTNAME CODE
I want to isolate the firstname and lastname from the code noting that the lastname can contain more than a word.
I thought about spliting all the string based on space separator but the problem is that the name can sometimes be composed of more than two words.
Can you show me please the steps to follow to acheive that?
Split the rows with Step "Split Fields". Then concatenate the fields for lastname1 or lastname2OrCode if person has 2 last names, otherwise set the code field.
And this simple Javascript (Do not forget to click at Get variables)
var lastname;
var code;
if(codeTmp==null){
code = lastname2OrCode;
lastname= lastname1;
}else {
lastname = lastname1+ " "+ lastname2OrCode;
code = codeTmp;
}

I'm new to MS Access.
So, I wrote a SQL query(query name = qryEmployeeInfo) which shows employee information. The query outputs two columns. The employee ID(header name = employee_ID) and the corresponding employee address(header name = employee_address).
My Access form has a text box(text box name = txtEmployeeID) that I want the user to be able to enter the employee_ID into and have it output the corresponding employee_address into another text box (text box name = txtEmployeeAddress). I also want the employee_address to be in the format of a string variable so I can perform other VBA checks on it later(for example - if LIKE "California" THEN...something).
I want to write what (I think) is called an injection SQL query so that I can pull the address data from the query for that specific employee_ID. I believe the format should look like this:
Dim rs As Recordset
Set rs = CurrentDb.OpenRecordset("select employee_address from qryEmployeeInfo where employee_ID = "' & txtEmployeeID & "'", dbOpenDynaset)
Do I have this written correctly?
If so, then how do I get that output into a string variable format(variable name = strEmployeeAddress)?
After I get the employee address into a string variable format I want to simply use txtEmployeeAddress.value = strEmployeeAddress to populate the employee address text box. Again, I also want the employee_address to be in the format of a string variable so I can perform other VBA checks on it later(for example - if LIKE "California" THEN...something).
Any help you could provide would be greatly appreciated.
If employee_ID is a number field, remove apostrophe delimiters.
If employee_ID is a text field, move first apostrophe so it is within quote marks.
"select employee_address from qryEmployeeInfo where employee_ID = '" & txtEmployeeID & "'"
Then txtEmployeeAddress = rs!employee_address
However, instead of opening a recordset object, could just use DLookup.
txtEmployeeAddress = DLookup("employee_address", "qryEmployeeInfo", "employee_ID =" & txtEmployeeID)
Or even better, eliminate the VBA. The DLookup() expression can be in textbox ControlSource property, just precede with = sign.
However, domain aggregate functions can perform slowly. So instead of textbox, use a combobox for selecting employee. Include employee information in combobox RowSource. Expression in textbox references column of combobox: =combobox.Column(1). Issue is combobox has limit on how many characters can be pulled into column so if field is memo (long text) type, this approach is not feasible and should use DLookup.
The address will be available in textbox for use as long as this form is open. If you want the address to be available to other procedures even after form is closed, then need to set a global or public variable. Such variable must be declared in a module header to make it available to multiple procedures. TempVars are another way to hold values for future use. I have never used them.
I have a name textbox and I want to find any names included in the typed text in the database table patient details name column. I know how to use LIKE operator if you know the letters you want the search to start/end with etc. but this time I want textbox. I think my issue is with the quotations; I tried to play around with it but it didn't work!
From x in PatientDetails where ( x.Patient_Name Like '%" Textbox1.Text "%' )
For example: If a Patient name in the database is: John Matt
and a user typed Matt, the above record for John Matt should be returned.
P.S I tried looking it up in Google but it mostly discuss characters not entered text box
Thank you all.
Something like this would do
C#
var query = (from x in PatientDetails
where x.Patient_Name.Contains(Textbox1.Text)
select x).ToList();
VB.NET - Converted using CodeConverter
Dim query = (From x In PatientDetails Where
x.Patient_Name.Contains(Textbox1.Text)x).ToList()
I have two fields in my dataset [FirstName] and [LastName]. I get an System.Data.EnumerableRowCollection Object with the following query:
Dim query = From dt In _dataset.DataTable1
Where TeamName = "The Avangers"
Select dt.FirstName , dt.LastName
I am looking for a way to merge the FirstName and LastName to get a StringArray with the following entries:
Item(0): "Banner, Bruce"
Item(1): "Stark, Tony"
Item(2): "Rogers, Steve"
...
What I did is I performed a separate query for First and LastName so I could use .ToArray on both queries. Afterwards I merged them in a for each loop. Just wanted to ask if there is a faster way to perform that.
Just concatenate your FirstName and LastName in your query and then apply ToArray at the end.
Select dt.LastName + ", " & dt.FirstName
I'm creating an application that allows users to create a form, which can then be loaded and filled out by another user, and that user's submission can then be viewed.
A Form is filled with Fields. When a user fills the form, a Submission database object is created, and this submission has a 1-M relationship with FieldValue objects. A FieldValue object has a FK to a Field, and stores a String of the user's input. Using this design, to view a submission, I read through the FieldValues associated with the Submission, and load the associated Field object, and fill it with the user's input. Everything works well in this sense, but my problem is in searching for these submissions.
I'm working on a search page, where I dynamically creat search fields based on the Fields of the Form that's being searched on. For example firstName and lastName. Let's say that the user searches with firstName = j lastName = smith. Using these search fields, I want to search for all submissions that have a FieldValue where the FK matches to firstName and the text contains "j" AND has A DIFFERENT FieldValue where the FK matches to lastName and the text contains "smith"
I have been trying variations of the following code:
Expression exp = ExpressionFactory.matchExp(Submission.FORM_PROPERTY, _formId);
for (SearchField searchField : searchFields)
{
Expression fieldExp = ExpressionFactory.matchExp(Submission.FIELD_VALUE_PROPERTY +"." + FieldValue.FIELD_PROPERTY, searchField.getFieldId());
fieldExp = fieldExp.andExp(ExpressionFactory.likeIgnoreCaseExp(Submission.FIELD_VALUE_PROPERTY +"." + FieldValue.TEXT_PROPERTY, "%" + searchField.getText() + "%" ));
exp = exp.joinExp(Expression.AND, fieldExp);
}
SelectQuery query = new SelectQuery(Submission.class, exp);
What I'm trying to do is loop through each of the search fields, and add it to the list of FieldValues that must be in the Submission. The problem with this is that it keeps searching for ONE FieldValue that has all of those values, and so, obviously fails. I have never done a search that could be a 1-M within another class, so I assume that I'm missing something here. Any help would be greatly appreciated. I apologize for the small novel in trying to describe what's going on, but it's a bit out of the ordinary for me.
You will need to build an Expression that creates M joins. "Splits" and "aliases" control how joins are generated. Since you have more than one criteria for each join, splits won't work, so using explicit aliases is more appropriate. Just let SelectQuery know what each alias means.
import static org.apache.cayenne.exp.ExpressionFactory;
int len = searchFields.size();
String[] aliases = new String[len];
for (int i = 0; i < len; i++) {
SearchField f = searchFields[i];
aliases[i] = f.getFieldId();
Expression e = matchAllExp(alias +"." + FieldValue.FIELD_PROPERTY, f.getFieldId());
e = e.andExp(likeIgnoreCaseExp(alias +"." + FieldValue.TEXT_PROPERTY, "%" + f.getText() + "%" ));
exp = exp.joinExp(Expression.AND, e);
}
SelectQuery query = new SelectQuery(Submission.class, exp);
query.aliasPathSplits(Submission.FIELD_VALUE_PROPERTY, aliases);
I want to create a report by using BIRT. I have 5 SQL criterias as the parameter for the report. Usually when I have 3 criterias, I am using nested if-else for the WHERE statement with javascript.
Since right now I have more criteria it becomes more difficult to write the code and also check the possibilities, especially for debug purposes.
For example the criteria for table employee, having these 5 criterias : age, city, department, title and education. All criteria will be dynamic, you can leave it blank to show all contents.
Do anyone know the alternative of this method?
There is a magical way to handle this without any script, which makes reports much easier to maintain! We can use this kind of SQL query:
SELECT *
FROM mytable
WHERE (?='' OR city=? )
AND (?=-1 OR age>? )
AND (?='' OR department=? )
AND (?='' OR title=? )
So each criteria has two dataset parameters, with a "OR" clause allowing to ignore a criteria when the parameter gets a specific value, an empty value or a null value as you like. All those "OR" clauses are evaluated with a constant value, therefore performances of queries can't be affected.
In this example we should have 4 report parameters, 8 dataset parameters (each report parameter is bound to 2 dataset parameters) and 0 script. See a live example of a report using this approach here.
If there are many more criteria i would recommend to use a stored procedure, hence we can do the same with just one dataset parameter per criteria.
Integer parameter handling
If we need to handle a "all" value for an integer column such age: we can declare report parameter "age" as a String type and dataset parameters "age" as an integer. Then, in parameters tab of the dataset use a value expression instead of a "linked to report parameters". For example if we like a robust input which handles both "all" "null" and empty values here is the expression to enter:
(params["age"].value=="all" || params["age"].value=="" || params["age"].value==null)?-1:params["age"].value
The sample report can be downloaded here (v 4.3.1)
Depending on the report requirements and audiance you may find this helpful.
Use text box paramaters and make the defualt value % (which is a wild card)
SELECT *
FROM mytable
WHERE city like ?
AND age like ?
AND department like ?
AND title like ?
This also allows your users to search for partial names. if the value in the city text box is %ville% it would return all the cities with "ville" anyplace in the city name.
If report parameters to be included in SQL-WHERE clause would be named according to some naming convention, for instance query_employee_[table column name], you could write Java-Script code in a generic way, so that you will not have to change it when new reporters being added.
for each param in params {
if param.name starts with query_employee_ {
where_clause += " and " + param.name.substring(after query_employee) + " == '" + param.value + "'";
}
}
You will have to check type of a parameter to make a decision whether you have to quote the parameter value.
The event handler could look as follows (implemented in Java, but it should be possible to port it to JavaScript, if you really need it to be in JavaScript):
public class WhereConditionEventHandler extends DataSetEventAdapter {
#Override
public void beforeOpen(IDataSetInstance dataSet,
IReportContext reportContext) throws ScriptException {
super.beforeOpen(dataSet, reportContext);
String whereClause = " where 1 = 1 ";
SlotHandle prms = reportContext.getDesignHandle().getParameters();
for (int i = 0; i < prms.getCount(); i++) {
if (prms.get(i) instanceof ScalarParameterHandle) {
ScalarParameterHandle prm = (ScalarParameterHandle) prms.get(i);
int n = prm.getName().indexOf("sql_customer_");
if (n > -1) {
String prmValue = "" + reportContext.getParameterValue(prm.getName());
if (DesignChoiceConstants.PARAM_TYPE_STRING.equals(prm.getDataType())) {
prmValue = "'" + prmValue + "'";
}
whereClause += " and " + prm.getName().substring("sql_customer_".length()) + " = " + prmValue;
}
}
}
System.out.println("sql: " + whereClause);
dataSet.setQueryText(dataSet.getQueryText() + whereClause);
}
}
By the way, you can pass in parameters that are not registered as report parameters in the BIRT report design. BIRT will nevertheless put them into "params" array.
