I have two tables tbl1 and tbl2 in which data is shown below, I want to fetch the data by combining two tables.
tbl1 data:
SLNO CALENDAR_RNO PLNDHRS STATUS_FLAG
30 64 0.78 0
30 54 0.78 1
30 55 0.78 2
30 70 0.29 0
tbl2 data:
SLNO CALENDAR_RNO PLNDHRS
30 53 0.20
30 54 0.10
30 55 0.70
30 56 0.30
30 58 0.18
30 60 0.70
30 62 0.50
30 66 0.70
30 68 0.90
I want to get all the records from tbl2 and get the records from tbl1 which are STATUS_FLAG = 0
.
I tried this query but I am not getting exact
SELECT SLNO,CALENDAR_RNO,PLNDHRS
FROM tbl1 INNER JOIN tbl2 ON tbl1.SLNO = tbl2.SLNO
WHERE tbl2.STATUS_FLAG = 0;`
But i need the table as given below:
SLNO CALENDAR_RNO PLNDHRS
30 53 0.20
30 54 0.10
30 55 0.70
30 56 0.30
30 58 0.18
30 60 0.70
30 62 0.50
30 64 0.78
30 66 0.70
30 68 0.90
30 70 0.29
Help me out from this problem. I am beginner to MySQL Language.
It seems you just want to union the two tables:
SELECT SLNO, CALENDAR_RNO, PLNDHRS
FROM tbl1
WHERE STATUS_FLAG = 0
UNION
SELECT SLNO, CALENDAR_RNO, PLNDHRS
FROM tbl2
The query selects all records of tbl2
and unions them will records of tbl1
having STATUS_FLAG = 0
. Duplicates are left out.
