To create a sequence inyour own schema, you must have theCREATESEQUENCEsystem privilege. 在自己模式下创建序列需要create sequence权限 To create a sequence inanother user’s schema, you must have theCREATEANYSEQUENCEsystem privilege. 在其他用户模式下创建序列需要create any sequence权限。 语法:Syntax 如...
To create a sequence in another user's schema, you must have theCREATEANYSEQUENCEsystem privilege. create_sequence::= Semantics schema Specify the schema to contain the sequence. If you omitschema, then Oracle Database creates the sequence in your own schema. sequence Specify the name of the s...
ORACLE sequence创建示例: create sequence bys.test_seq increment by 3 start with 5 maxvalue 18 minvalue 4 cycle cache 4; 在bys用户下创建名为test_seq的sequence 从5开始,每次增加3,最大值是18,最小值是4 允许重用,cache 4 表示会缓存四个序列号,比如5 8 11 14 ...
To create a sequence inanother user's schema, you must have theCREATEANYSEQUENCEsystem privilege.在其它用户模式下创建序列须要create any sequence权限。 语法:Syntax 假设不加条件语句,默认创建的序列格式例如以下: -- Create sequence createsequenceSEQ_T ...
In this tutorial, you will learn how to use the Oracle CREATE SEQUENCE statement to create a new sequence in Oracle.
创建：create sequence seq_test minvalue 1 maxvalue 21 start with 1 increment by 1 cache 20 cycle order;minvalue 1 / nominvalue：最小值为1 maxvalue 21 / nomaxvalue：最大值为21 start with 1：从1开始计数 increment by 1：每次增加1 cache 20 / nocache：缓存20个sequence值 / ...
Oracle SEQUENCE 特性 START WITH 边界 默认情况下是认为MINVALUE>=START WITH>=MAXVALUE,超出区间就不能创建SEQUENCE START WITH比MINVALUE小创建失败: oracle> create SEQUENCE MY_FIRST_SEQUENCE start with -2 increment by -1 minvalue 1 maxvalue 100 ...
