Hi,
I am having a tough time understanding why the following query returns 6 rows for the PK_FLD = 230? Here are the two tables:
Table A
PK_FLD ID_NAME
230 ABC
510 ABC
511 ABC
512 ABC
TableB
PK_FLD
230
510
512
511
722
select TABLEA.PK_FLD FROM TABLEA JOIN TABLEB ON TABLEA.PK_FLD = TABLEB.PK_FLD
WHERE TABLEA.ID_NUMBER = "ABC"
I thought that the resulting query should have 4 rows but what is returned is:
230
230
230
230
230
230
510
511
512
Could someone explain why? TIA
