I used the Execute SQl task editor with the statement as shown below and assigned the result to the variable NA_ID_DECIMAL which well declared. I encountered error which the error msg shown as below.I had tried the variable with different data type like Double,Int32,Int64,UInt32 and UInt64, but same error encounter.For this situation what data type for the variable that i still able to use? Thanks Note : tbSYS_Param_UnknownCode.NA_ID_DECIMAL data type in the table is decimal(28,2) SELECT tbSYS_Param_UnknownCode.NA_ID_DECIMAL FROM tbSYS_Param_UnknownCode Error: The type of the value being assigned to variable "User::NA_ID_DECIMAL" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
