Get all Rows from QUERY() into one cell in a Google Spreadsheet - google-sheets

Question

I have the following formula in a spreadsheet:
=IFERROR( JOIN( CHAR(10), QUERY(Schedule!$A$2:$E, "SELECT C, D, E Where A = '" & B$2 & "' AND B = timeofday '" & text($A4, "HH:MM:SS") & "' AND C = '" & $C$1 & "'", -1)),)
It works great when it returns one row. It does not work if it returns multiple rows. How can I get it to use all rows returned with a CHAR(10) included between rows as well as columns. Basically I want all the returned data separated by line breaks. So when the QUERY returns
Item1 Item2 Item3
Item1A Item2A Item3A
it is changed to
Item1
Item2
Item3
Item1A
Item2A
Item3A
My goal is to put all the returned data in 1 cell with a line break between each item. Any way I can make this happen?
Here is a copy of the file. Cells B3 to F4 are good sample cells where the formula reside.

Answer 1

The solution is imperfect, it adds extra spaces before each line:
Item1 Item2 Item3
Item1A Item2A Item3A
^ spaces
Step1
Get origilal formula + extra column in query:
=QUERY(data, "SELECT C, D, E, '##' Where" & ... & "' label '##' ''", -1)
The result:
Item1 Item2 Item3 ##
Item1A Item2A Item3A ##
Step2
Replace "##" with char(10)
=ARRAYFORMULA(SUBSTITUTE(step1Formula,"##",char(10)))
Item1 Item2 Item3
Item1A Item2A Item3A
^ new lines
Step3
Use concatenate:
=ArrayFormula(" "&TRIM(CONCATENATE(" "&B16:E17)))
Final formula
=ArrayFormula(" "&TRIM(CONCATENATE(" "&SUBSTITUTE(QUERY(Schedule!$A$2:$E, "SELECT C, D, E, '##' Where A = '" & B$2 & "' AND B = timeofday '" & text($A3, "HH:MM:SS") & IF(OR($C$1 = "*",ISBLANK($C$1)), "", "' AND C = '" & $C$1) & IF(OR($F$1 = "*",ISBLANK($F$1)), "", "' AND E = '" & $F$1) & "' label '##' ''", -1),"##",char(10)))))

I know this is not an elegant solution, but it will help you in your case. Enter this formula at B3 and then copy and paste it onto other cells.
=iferror(join(char(10), query(Schedule!$A$2:$E, "select C,D,E where A='"&B$2&"' and B=timeofday '"&text($A3, "hh:mm:ss")&"' limit 1 offset 0")),"")
&iferror(char(10)&char(10) & join(char(10), query(Schedule!$A$2:$E, "select C,D,E where A='"&B$2&"' and B=timeofday '"&text($A3, "hh:mm:ss")&"' limit 1 offset 1")),"")
&iferror(char(10)&char(10) & join(char(10), query(Schedule!$A$2:$E, "select C,D,E where A='"&B$2&"' and B=timeofday '"&text($A3, "hh:mm:ss")&"' limit 1 offset 2")),"")
&iferror(char(10)&char(10) & join(char(10), query(Schedule!$A$2:$E, "select C,D,E where A='"&B$2&"' and B=timeofday '"&text($A3, "hh:mm:ss")&"' limit 1 offset 3")),"")
&iferror(char(10)&char(10) & join(char(10), query(Schedule!$A$2:$E, "select C,D,E where A='"&B$2&"' and B=timeofday '"&text($A3, "hh:mm:ss")&"' limit 1 offset 4")),"")
Basically you cannot concat result strings with google query(), so instead I'd fetch one row at a time using limit 1 offset 0, limit 1 offset 1, limit 1 offset 2, and so on. Maximum is 5 in this case. Sample sheet is here.
