GAUSS-01921: "return type of transition function %s is not %s"

SQLSTATE: 42804

Description: The return type generated based on transfn is inconsistent with the specified type.

Solution: Ensure that the return type for the composite type is consistent with the specified type.

GAUSS-01922: "must not omit initial value when transition function is strict and transition type is not compatible with input type"

SQLSTATE: 42P13

Description: When the conversion function is strict and inconsistent with the input type, pay attention to the type of the initial value.

Solution: Ensure that the type of the initial value is consistent with that of the conversion type. Alternatively, it must be at least compatible with binary data.

GAUSS-01923: "return type of collection function %s is not %s"

SQLSTATE: 42804

Description: The return type of the collection function is different from the expected aggTreanType.

Solution: Call the correct collection function.

GAUSS-01924: "cannot determine result data type"

SQLSTATE: 42804

Description: The result data type cannot be determined because no parameter input exists.

Solution: Check and correct the type of the parameter input.

GAUSS-01925: "sort operator can only be specified for single-argument aggregates"

SQLSTATE: 42P13

Description: Sorting operators can be specified only for single-parameter aggregate functions.

Solution: Check the number of parameters of the aggregate function and whether the sorting operator needs to be called.

GAUSS-01926: "function %s returns a set"

SQLSTATE: 42804

Description: The aggregate function can return only single value but not a set.

Solution: Check whether the aggregate function is correct.

GAUSS-01927: "function %s requires run-time type coercion"

SQLSTATE: 42804

Description: The function requires type coercion during execution but the type coercion is not performed in the nodeAgg.c file.

Solution: Ensure that no type conversion exists during the execution.

GAUSS-01928: "cannot drop %s because %s requires it"

SQLSTATE: 2BP01

Description: This object cannot be deleted because other objects depend on it.

Solution: Remove the dependency relationship or delete the dependent object.
