When you add or average integer data , microsoft sql server 2005 database engine treats the result as an 將整數(shù)數(shù)據(jù)相加或求其平均值時(shí),即使列的數(shù)據(jù)類型為
Precision radix of approximate numeric data , exact numeric data , integer data , or monetary data 近似數(shù)值數(shù)據(jù)、精確數(shù)值數(shù)據(jù)、整數(shù)數(shù)據(jù)或貨幣數(shù)據(jù)的精度基數(shù)。
Which respectively denote string and integer data , are the workhorses for most xml - rpc programs > (分別表示字符串和整數(shù)數(shù)據(jù))在大部分xml - rpc程序中廣為使用。
For example , an index is ideal for columns that have an integer data type and are also unique or nonnull columns 例如,某個(gè)索引對(duì)于含有整數(shù)數(shù)據(jù)類型同時(shí)還是唯一的或非空的列是理想索引。
The two properties must be compatible : for example , the use of a string value together with an integer data type is not valid 這兩種屬性必須兼容:例如,字符串值不能與整數(shù)數(shù)據(jù)類型一起使用。
For example , you might change the data type of a column that contains only integer data to a numeric data type , such as dt i2 例如,可以將只包含整型數(shù)據(jù)的列的數(shù)據(jù)類型更改為數(shù)值數(shù)據(jù)類型,例如dt _ i2 。
Visual basic updates the integer data types for interoperability with other programming languages and with the common language runtime Visual basic更新了整數(shù)數(shù)據(jù)類型,旨在提供與其他編程語言和公共語言運(yùn)行庫的互操作性。
Method will always be an integer , which you can specify by using the java . sql . types . integer data type . in addition , when you pass a value to the 方法中為返回狀態(tài)參數(shù)指定的值將始終為整數(shù),您可通過使用java . sql . types . integer數(shù)據(jù)類型進(jìn)行指定。
Similarly , if a column with the dt cy data type can meet the package data requirements by using an integer data type instead , you can change the data type to dt i4 同樣,如果數(shù)據(jù)類型為dt _ cy的列改用整數(shù)數(shù)據(jù)類型可以滿足包數(shù)據(jù)要求,則可以將數(shù)據(jù)類型更改為dt _ i4 。
When the package first runs the transformation , the transformation copies the reference table , adds a key with an integer data type to the new table , and builds an index on the key column 當(dāng)包首次運(yùn)行轉(zhuǎn)換時(shí),該轉(zhuǎn)換將復(fù)制引用表,然后將具有整數(shù)數(shù)據(jù)類型的鍵添加到新表中,接著生成該鍵列的索引。
