-390 THE FUNCTION function-name, SPECIFIC NAME specific-name, IS NOT VALID IN THE CONTEXT WHERE IT IS USED
Explanation
A function resolved to a specific function that is not valid in the context where it is used.
- function-name
- The name of the function.
- specific-name
- The specific name. If specific-name is an empty string, then the function resolved to the built-in function identified by function-name.
Possible causes for this error include:
- A scalar or aggregate function is referenced where only a table function is allowed (such as in the FROM clause of a query).
- A
table function is referenced where only a scalar or aggregate function is allowed (such as in an
expression).
- A
function is referenced in a SOURCE clause of a CREATE FUNCTION statement, but a source function
cannot be defined on that function (or on that specific function signature).
- Function XMLMODIFY is referenced where it is not the topmost expression on the right side of the SET assignment clause in an update.
System action
The statement cannot be processed.
Programmer response
Ensure that the correct function name and arguments are specified and that the SQL path includes the schema where the correct function is defined. You might need to change the function name, arguments, or SQL path (using SET CURRENT PATH or the PATH bind option), or change the context in which the function is used.
