问题
Am trying to Fetch Only one record from the Sybase Table without using the RowCount Function, even though "WHERE Condition" returns multiple results.
SELECT TOP 1 EMPLOYEE_NAME FROM EMPLOYEES WHERE EMPLOYEEID > 50
Runs Successfully with one Record Only,
However
SELECT TOP 1 EMPLOYEE_NAME FROM EMPLOYEES WHERE EMPLOYEEID > 50
fails, when written inside a Sybase Procedure as a Sub Query
回答1:
Top is supported only in outer query only, here is the link
For ordered data I am using having cause instead Top 1 in Sybase, like:
SELECT EMPLOYEE_NAME FROM EMPLOYEES WHERE EMPLOYEEID > 50 HAVING EMPLOYEEID = MIN(EMPLOYEEID)
I hope it helps a bit. GL!
回答2:
I know it is late but just for others TOP inside a subquery can be used in sybase latest version.
