The vector data type stores vector data optimized for machine learning applications and similarity search operations.
SQL Server还能自动限制每个数据类型的取值范围,例如定义了一个类型为int的字段,如果插入数据时插入的值的大小在smallint或者tinyint范围之内,Sql Server会自动将类型转换为smallint或者tinyint,这样一来,在存储数据时,占用的存储空间只有int的1/2或则1/4. SQL Server数据库管理系统中的数据类型可以分为两类,分别是...
COLUMN_NAME、DATA_TYPE 和ORDINAL_POSITION 必須傳回有效的非 Null 值。 如果 DATA_TYPE 是DBTYPE_NUMERIC 或DBTYPE_DECIMAL,對應的 NUMERIC_PRECISION 和NUMERIC_SCALE 必須是有效的非 Null 值。 從選擇性 INDEXES 結構描述資料列集,SQL Server 會根據上述規則設定限制,以在指定的遠端資料表上尋找索引。 ...
