Deleting records.

Anyone have ideas on how to delete records (see code below). I keep on getting the error message:

"The column prefix 'employee' does not match with a table name or alias name used in the query."

All I want to do is to remove the records in the EMPRATES table where the EMPLOYEEID and RATE are the same in the EMPLOYEE table. What am I missing?

delete emprates
where
emprates.employeeid = employee.employeeid
and emprates.rate=employee.ratedelete emprates from emprates
inner join employee on
emprates.employeeid = employee.employeeid
and emprates.rate=employee.rate|||delete from emprates
where exists
( select 1 from employee
where employeeid = emprates.employeeid
and rate = emprates.rate )|||I tried both syntax and they both perfomed what I needed. The first one had a lower execution cost though.

Thanks again.sql

deleting data using table prefix

I can run a select to retrieve data using a prefix 'a' for the specific table involved. However when I try to run a delete using the same criteria it fails telling me

Msg 102, Level 15, State 1,.......Line 1

Incorrect syntax near 'a'

The Select statement looks like:

select count(*) from schema.table a where a.customer_id=1234

The Delete looks like:

delete from schema.table a where a.customer_id=1234

What am I doing wrong here? and how can I prefix the table, because the command I want to run is much more complicated than the example above and it needs the prefix

According to BOL there is no alias for delete statement

Thanks

You can use the TSQL extension for the DELETE statement like:

delete from schema.table

from schema.table a

where a.customer_id=1234
