The following table lists the data type for the result of REGR_COUNT(y,x).
Mode | Data Type |
---|---|
ANSI | If MaxDecimal in DBSControl is…
|
Teradata | INTEGER |
The result type of REGR_COUNT is consistent with the result type of COUNT for ANSI transaction mode and Teradata transaction mode.
When in Teradata mode, if the result of REGR_COUNT overflows and reports an error, you can cast the result to another data type, as illustrated by the following example.
SELECT CAST(REGR_COUNT(weight,height) AS BIGINT) FROM regrtbl;
Here are default formats and titles for the result of REGR_COUNT.
- If operand y is numeric or character, the format is:
- For ANSI mode, if MaxDecimal in DBSControl is:
0 or 15, the format is -(15)9
18, the format is -(18)9
38, the format is -(38)9
- For Teradata mode, the format is the default format for INTEGER
- For ANSI mode, if MaxDecimal in DBSControl is:
- If operand y is UDT, the format is the format for the data type to which the UDT is implicitly cast.
