Hi All,
We are creating a function using 'CREATE FUNCTION'. Within the function, we would like to access our previously defined environment variable, which is structured as:
<Environment>
<Field>Data</Field>
<Field>Data</Field>
<Field>Data</Field>
</Environment>.
Is there a way to pass this environment variable to the created function?
The function looks something like:
CREATE FUNCTION CHeckIsNull (FieldName CHAR, TotalCount INT) RETURNS Char
BEGIN
DECLARE NullIndex INT;
DECLARE IsNull CHAR;
SET NullIndex = 1;
SET IsNull = 'N';
WHILE IsNull = 'N' AND NullIndex <= TotalCount DO
IF Environment.Field[NullIndex] = FieldName THEN
SET IsNull = 'Y';
END IF;
SET NullIndex = NullIndex + 1;
END WHILE;
RETURN IsNull;
END;
This code is not deployable, indicating that 'Environment' is not a valid correlation name, but we have not been able to devise a way to pass the global environment variable to the function.
Any help would be greatly appreciated.
Thank you very much.

Use something like
CALL Audit(Environment, 'Audit Msg');
CREATE PROCEDURE Audit (IN Environment REFERENCE, IN remarks CHAR)
BEGIN
DECLARE auditRoot REFERENCE to Environment.Audit;
SET auditRoot.remarks = remarks;
END; |
