How to getRowSet using simple form of SQL?

I usually wrote SQL like this:
sSQL = "SELECT " & """ID""" & ", " & """FirstName""" & ", " & """LastName""" & ", " & """DateOfBirth""" & ", " & """Salary""" & " FROM " & """Table1""" & " WHERE " & """ID""" & " = " & "'1'"
But for the very long SQL, it is very difficult to write like that.

Is it possible to write:
"SELECT ID, FirstName, LastName, DateOfBirth, Salary FROM Table1 WHERE ID = 1"
and how to getRowSet in Sub Test2 ?

Sub Test2

	Dim sSQL, dbf 				As String
	Dim db, oStatement 			As Object
	Dim lesQueries, descrQuery 	As Object

	On Local Error GoTo CloseConnection
	dbf			= "file:///home/id00003/Documents/LibreOffice/LibreOfficeAskLibreOffice/0033SimpleFormSQL/0033SimpleFormSQL.odb"
	db 			= ConnectDatabase(dbf)
	oStatement 	= db.CreateStatement
	MsgBox "Connected"	

	lesQueries = db.QueryDefinitions
	descrQuery = lesQueries.createInstance
	descrQuery.Command = "SELECT ID, FirstName, LastName, DateOfBirth, Salary FROM Table1 WHERE ID = 1"
'How to getRowSet in Sub Test2 ?
	MsgBox "Found"

	MsgBox "Disconnected"	
	Exit Sub

	MsgBox "Error " & Err & ": " & Error$ & " (line : " & Erl & ")"

End Sub

Try in direct SQL (Tools → SQL):
SELECT "FirstName" FROM "Table1"
works well, while
SELECT FirstName FROM Table1
won’t work, because it will be interpreted by Firebird with uppercased fieldname and tablename:+
So the field an the table couldn’t be found.

could be written as

sSQL = "SELECT ""ID"", ""FirstName"", ""LastName"", ""DateOfBirth"", ""Salary"" 
FROM ""Table1"" WHERE ""ID"" = 1"

and in your special case, because you are asking for the whole table:

sSQL = "SELECT * FROM ""Table1"" WHERE ""ID"" = 1"

Get a result of a query:

oConnection = oDatasource.ActiveConnection()
oSQL_Command = oConnection.createStatement()
oResult = oSQL_Command.executeQuery(sSQL)
inID = oResult.getInt(1)
stFirstName = oResullt.getString(2)

WHILE - WEND isn’t needed in you special case, because it is only one row. But there will be errors if there isn’t any row.

once again you do not supply vital relevant detail.
I was wondering why the spreadsheet? you don’t mention the custom menu ‘LO Calc BASIC Test’.
RobertG has answered the question ‘How to getRowSet using simple form of SQL?’.
you wish to execute the query:
SELECT ID, "FirstName", "LastName", "DateOfBirth", "Salary" FROM "Table1" WHERE ID = 1
this query returns a single record WHERE ID = 1.
you need to tell how and from where the value of ID is obtained, it will obviously vary and impact the coding if indeed coding is actually required.
it’s unlikely that you will be executing via the spreadsheet unless of course the value of ID is taken from that spreadsheet.
you may use a parameter query(unsuitable for macro), filter table, manually insert into macro via the IDE or several other possible sources.
the source will determine initial coding.
you can paste this code into any module, it should function with the database open or closed.
the database is accessed only to retrieve table data.
it should be executed from the IDE.
destination was not indicated so is via msgbox, the formatting is not great due to proportional font.
hopefully this helps in finding a solution.
