I need to covert the following MS SQL query to Oracle.

Question

The query is as follows..
SELECT B.AL_DESCRIPTION,Count(C.TC_STATUS)
FROM ALL_LISTS A, ALL_LISTS B, TESTCYCL C
Where B.AL_FATHER_ID = A.AL_ITEM_ID
And C.TC_STATUS = B.AL_DESCRIPTION
And A.AL_DESCRIPTION = 'Status'
And (C.TC_EXEC_DATE = @ExecutionDate@
Or C.TC_STATUS = 'No Run')
Group By B.AL_DESCRIPTION
Union
SELECT B.AL_DESCRIPTION,0
FROM ALL_LISTS A, ALL_LISTS B
Where B.AL_FATHER_ID = A.AL_ITEM_ID
And A.AL_DESCRIPTION = 'Status'
And Not Exists (Select 1 From TESTCYCL C Where C.TC_STATUS = B.AL_DESCRIPTION)
Order By 1

Answer 1

Is
What does this below mean in MySql
And (C.TC_EXEC_DATE = @ExecutionDate@Is ExecutionDate a variable name?
Then replace it by..
And (C.TC_EXEC_DATE = TO_DATE(ExecutionDate,'DD-MON-YYYY')If ExecutionDate is not a date datatype
I guess you are trying to compare the value of TC_EXEC_DATE with some variable value.
If you are using bind variable then you can substitute as
And (C.TC_EXEC_DATE = TO_DATE(&ExecutionDate,'DD-MON-YYYY')check this,
Here I am taking value at run time.
