I need to perform the following select:
select c.address from Customer c where lower(trim(c.name)) = :name
But I get the following exception:
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
Any idea how can I combine trim with lower?
I discovered the solution, you must use both in order for the statment to work:
select c.address from Customer c where lower(trim(both from c.name)) = :name

I'm new to writing case statements in NetSuite and would appreciate any input with this. I'm trying to create following statement within item search, but receiving invalid expression error.
CASE WHEN {transaction.status} = "Purchase Order:Pending Receipt" THEN {transaction.expectedreceiptdate} end
CASE WHEN {transaction.status} = 'Pending Receipt' THEN {transaction.expectedreceiptdate} end
Note that you need to use single quotes in SQL statements, and you can't specify the transaction type as part of the status condition. To work araound this, you could include the transaction type in the criteria, or add another condition within the CASE statement:
CASE WHEN {transaction.status} = 'Pending Receipt' AND {transaction.type} = 'Purchase Order' THEN {transaction.expectedreceiptdate} end
I have a field named field, and I would like to see if it is null, but I get an error in the query, my code is this:
let
Condition= Excel.CurrentWorkbook(){[Name="test_table"]}[Content],
field= Condition{0}[fieldColumn],
query1="select * from students",
if field <> null then query1=query1 & " where id = '"& field &"',
exec= Oracle.Database("TESTING",[Query=query1])
in
exec
but I get an error in the condition, do you identify the mistake?
I got Expression.SyntaxError: Token Identifier expected.
You need to assign the if line to a variable. Each M line needs to start with an assignment:
let
Condition= Excel.CurrentWorkbook(){[Name="test_table"]}[Content],
field= Condition{0}[fieldColumn],
query1="select * from students",
query2 = if field <> null then query1 & " some stuff" else " some other stuff",
exec= Oracle.Database("TESTING",[Query=query2])
in
exec
In query2 you can build the select statement. I simplified it, because you also have conflicts with the double quotes.
I think you're looking for:
if Not IsNull(field) then ....
Some data types you may have to check using IsEmpty() or 'field is Not Nothing' too. Depending on the datatype and what you are using.
To troubleshoot, it's best to try to set a breakpoint and locate where the error is happening and watch the variable to prevent against that specific value.
To meet this requirement, I would build a fresh Query using the PQ UI to select the students table/view from Oracle, and then use the UI to Filter the [id] column on any value.
Then in the advanced editor I would edit the generated FilteredRows line using code from your Condition + field steps, e.g.
FilteredRows = Table.SelectRows(TESTING_students, each [id] = Excel.CurrentWorkbook(){[Name="test_table"]}{0}[fieldColumn])
This is a minor change from a generated script, rather than trying to write the whole thing from scratch.
This is my first question on the forum, but reading previous questions has been enormously helpful in the project I'm working on, so already my thanks. I couldn't find an answer to this, but apologies if I overlooked something.
I am writing an excel macro in vba, and am trying to create a select case... statement in which the expression has a variable boolean and numeric component. For example, the macro can pull "> 3" or "< 3" from another worksheet.
My hope had been that I could assign to a string all of these parameters, i.e.:
test1 = "is " & BoolOperator1 & " " & NumericValue1
and then
Select case ValuetoCompare
Case test1
'Do something
Case test2
'...
Is there a way to do this? I suppose the alternative would be to nest the case with the numeric variable inside a select function that determines the operator, but I thought this would be more elegant.
Thanks in advance for your guidance--
Josh
Assuming that you'll get a string BoolOperator1 that is a valid operator, e.g. >=, =, and a numeric value NumericValue1, the easiest way to execute this comparison on another numeric value ValueToCompare is to use the Evaluate function. This will execute a string as VBA and return it's result.
In your case, you could simply use:
If Evaluate(ValueToCompare&BoolOperator1&NumericValue1) Then ...
If you want to use this in a Select Case statement, you'd either need to use a simple If ... ElseIf ... statement - or use this trick:
Select Case True
Case Evaluate(ValueToCompare&BoolOperator1&NumericValue1): ...
Case Evaluate(ValueToCompare&BoolOperator2&NumericValue2): ...
Case Else ...
End Select
In my Lotus Notes script, i do have this piece of logic as shown below. This is basically for two SELECT statements, followed by Fetch for each of the SELECT statement separately and the SELECT is for the same DB2 table with a variation in WHERE clause. The error i'm getting is for the second FETCH. The error i'm getting is ---> Field count mismatch error:
count = 0
If (srccon.Execute(selectstatement, fldLst1) = 0) Then
Goto GetNextDoc
End If
count = srccon.Fetch(fldLst1)
If ( count = 0 ) Then
Goto GetNextDoc
End If
The above cursor select and fetch does not give me any error.
The cursor down which is for the same DB2 table with a slight variation
in WHERE clause is causing the error:
count1 = 0
If (srccon.Execute(selectstatement1, fldLst) = 0) Then
Goto GetNextDoc
End If
count1 = srccon.Fetch(fldLst) ---> The error is pointing to this line
and the error is
I would appreciate any help in this regard. I would also thank the gentleman who
did excellent solution for my previous problem for current date minus 30 days.
With much thanks
I suspect it's because when you call Execute, you're reusing the same LCFieldList object from a previous call. Execute and Select statements append their list of result fields to the object you pass them, so you must pass them an empty fieldlist -- one you just created. Otherwise you get a combined fieldlist of all the fields in the result sets of multiple calls to Select or Execute.

I am having some trouble in converting the following
SELECT * FROM foo f WHERE
(f.name = 'name' AND f.date = '1980/02/2001')
OR
(f.name = 'another name' AND f.date = '1990/02/2001')
to
new Select().From(Foo.Schema.TableName)
.Where(Foo.Columns.Name).IsEqualTo('name')
.And(Foo.Columns.Date).IsEqualTo('1980/02/2001')
.Or(Foo.Columns.Name).IsEqualTo('another name')
.And(Foo.Columns.Date).IsEqualTo('1990/02/2001')
as you can see I am not aware of the method which can isolate two groups of "AND" and put each of them in an "OR" statement.
I would really appreciate your help in this context.
You need to wrap the parts in barckets using the .AndExpression() and .CloseExpression()
