到現在為止,一個抽象數據類型,一些可能的值及其的一些操作,例如一個的數據類型已經更加相似於一個類了。The data type of the shift amount operand must be
表示移位位數的操作數數據類型必須為An expression can use arguments and operands that have incompatible data types, and in that case the expression evaluator cannot perform implicit data conversion
表達式可使用數據類型不兼容的參數和操作數,在這種情況下,表達式計算器無法執行隱式數據轉換。However, if the column is a character data type and contains only numeric characters, you can indicate this by setting the numeric string option to y. this setting gives the federated compiler the option of allowing the data source to perform operations that are affected by different collating sequences - because numbers are always sorted the same
然而,如果列是字元數據類型,並且只包含數字字元,那麼可以通過將numeric _ string選項設置為「 y 」來表明這一點。這種設置使聯邦編譯器可以選擇允許數據源執行可能受不同排序序列影響的操作因為數字總是按相同順序排序。For more information about the coercion, conversion, and manipulation of the variant data type, see " variant and variantarg " in the platform sdk documentation
