创建序列后,您可以在 SQL 语句中使用CURRVAL伪列返回序列当前值或使用NEXTVAL伪列返回递增的新值。详细信息,请参见序列伪列。 语法 CREATESEQUENCE[schema.]sequence_name {STARTWITHint_value|[INCREMENTBYint_value]|[MINVALUE int_value|NOMINVALUE]|[MAXVALUE in
向当前数据库里增加一个新的序列。序列的Owner为创建此序列的用户。SEQUENCE是一个存放等差数列的特殊表,该表受DBMS控制。这个表没有实际意义,通常用于为行或者表生成唯一的标识符。如果给出一个模式名,则该序列就在给定的模式中创建,否则会在当前模式中创建。序列名必
在Oracle中,用以下SQL命令创建了一个序列:CREATE SEQUENCE my_seqSTART WITH 394INCREMENT BY 12NOMINVALU

In SQL Server, the sequence is a schema-bound object that generates a sequence of numbers either in ascending or descending order in a defined interval. It can be configured to restart when the numbers get exhausted. A Sequence is not associated with any table. You can refer a sequence to...

Gaps can still occur if numbers are requested using the NEXT VALUE FOR or sp_sequence_get_range functions, but then the numbers are either not used or are used in uncommitted transactions.When a sequence object uses the CACHE option, if you restart the sequence object, or alter the ...
The Create Sequence Tool allows users to visually create sequences. Note: RazorSQL does not provide the Create Sequence tool for all databases. The Create Sequence Tool allows users to create sequences and specify such information as the name of the sequence, the number to start with, the ...
