A value could not assigned or converted to a value in the specified SQL data type because either 1) the data type of the value can not be legally cast to the target data type (for example, data type TIME can not be converted to data type INTEGER); 2) the assignment of the value results in overflow in the target data type (for example, the decimal value 12345678.34 can not be assigned to data type DECIMAL(3,2) because the precision of the target type is exceeded); or 3) the syntax of a character string value is not appropriate for the target data type (for example, the string 'abc' can not be converted to data type DATE).
