Variables have a Variant data type and the expression evaluator converts the data type of a variable from a Variant subtype to an Integration Services data type before it evaluates the expression. 1,字符数据类型 字符变量和TSQL数据类型的映射关系: String:char,nchar,varchar(n),nvarchar(n) object:...
An implicit conversion of a data type occurs when the expression evaluator automatically converts the data from one data type to another. If the data in a column does not require the full width allocated by the source data type, you might want to change the data type of the column. Making...

隐式转换对用户不可见。 数据类型会自动从一种数据类型转换为另一种数据类型。 例如,当将一个字符串与一个int比较时,在比较进行之前,该字符串会隐式转换为int: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 SELECT*FROMTableWHERE[StringColumn]=[NumericColumn] ...

有时数据流组件还必须先将一种 Integration Services 数据类型转换为另一种数据类型,然后才能将该类型转换为托管类型。ConvertBufferDataTypeToFitManaged方法类将 Integration Services 数据类型映射到其他 Integration Services 数据类型,然后使用BufferTypeToDataRecordType方法将该数据类型映射到托管数据类型。
