ERROR 2616 Numeric overflow during computation while doing count(*)

Question

I am trying to do a `select count(*)` from table from a table and I am not able to do it because of this error. I am not aware of the number of rows in the table. I am not doing any other aggregation in my query apart from this. I guess it has something to do with the count value which is too large to be stored in INTEGER. What is the alternative?

Accepted Answer

When your session runs in Teradata mode the result of a COUNT is INTEGER as you already noticed (in ANSI mode it will be a DECIMAL with at least 15 digits).

The workaround is simple, cast it to a bigint:

```
SELECT CAST(COUNT(*) AS BIGINT)...
```
