Google Sheets Query to combine data from 3 sheets with different criteria - google-sheets

Question

I need to combine 3 sets of data vertically, using a Query. The first 2 data sources ('SOURCE 1'!A:T and EG:EZ) have the same conditions and I was able to combine them with no problem, but the 3rd data source ('SOURCE 3'!A:T) has different conditions and when I add this source I result in an error. The column headers will be identical in the output.
This is the formula containing ONLY the first 2 data sources, that works:
=QUERY({'SOURCE 1'!A:T;EG:EZ},"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'",1)
When adding in the 3rd data source, below are the 3 formulas I've tried, but all result in the error:
In ARRAY_LITERAL, an Array Literal was missing values for one or more rows.
Attempt 1:
={QUERY({'SOURCE 1'!A:T;EG:EZ},"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'",1);
QUERY('SOURCE 3'!A:T,"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col1 is not null")}
Attempt 2:
={QUERY('SOURCE 1'!A:T,"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'",1);
QUERY(EG:EZ,"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'");
QUERY('SOURCE 3'!A:T,"Select Col1,Col2,Col3,Col4,Col5,Col16,' ',Col8,Col9,Col10,Col11,Col12,Col13 where Col1 is not null")}
Attempt 3:
={QUERY('SOURCE 1'!A:T,"Select A,B,C,D,E,F,G,H,I,J,K,L,M where J >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and J <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and T = 'YES' and A starts with 'APP-' order by B,J,A,I label K 'NAME'",1);
QUERY(EG:EZ,"Select A,B,C,D,E,F,G,H,I,J,K,L,M where J >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and J <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and T = 'YES' and A starts with 'APP-' order by B,J,A,I");
QUERY('SOURCE 3'!A:T,"Select A,B,C,D,E,P,' ',H,I,J,K,L,M where A is not null")}
Any advice would be much appreciated. Thank you!

Answer 1

If you write QUERY(EG:EZ,"Select A,B,C,D,E,F,G,H,I,J,K,L,M you can't select A... within EG:EZ!
I suggest to change 'SOURCE 1'!A:T by {'SOURCE 1'!A:T} , idem for EG:EZ and then you will be able to use only Col1, Col2 etc. in your formula.
Try
={QUERY({'SOURCE 1'!A:T},"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'",1);
QUERY({EG:EZ},"Select Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8,Col9,Col10,Col11,Col12,Col13 where Col10 >= date '"&TEXT(B1,"yyyy-mm-dd")&"' and Col10 <= date '"&TEXT(D1,"yyyy-mm-dd")&"' and Col20 = 'YES' and Col1 starts with 'APP-' order by Col2,Col10,Col1,Col9 label Col11 'NAME'");
QUERY({'SOURCE 3'!A:T},"Select Col1,Col2,Col3,Col4,Col5,Col16,' ',Col8,Col9,Col10,Col11,Col12,Col13 where Col1 is not null")}
if there is a lack of data in one of the three queries, you will also get an error, in that case, add iferror(query______,{"","","",...} on each query
