Question

我正在尝试在Oracle中创建一个表我正在使用以下SQL：

CREATE TABLE SALES_TARGET(
SLS_REP_SK                 NUMBER(38, 0)    NOT NULL,
MARKET_PRODUCT_HRCHY_SK    NUMBER(38, 0)    NOT NULL,
FISCAL_PERIOD              VARCHAR2(6)      NOT NULL
                           CONSTRAINT VALID_FISCAL_PERIOD CHECK (LENGTH(FISCAL_PERIOD) = 6 AND REGEXP_LIKE(FISCAL_PERIOD, '^\d*$') AND (SUBSTR(FISCAL_PERIOD, 1, 4) BETWEEN '2010' AND '2050') AND (TO_NUMBER(SUBSTR(FISCAL_PERIOD, 5, 2)) BETWEEN 1 and 12)),
CURR_SK                    NUMBER(38, 0)    NOT NULL,
SALES_TARGET_AMT           NUMBER(18, 5)    NOT NULL
                           CONSTRAINT POSITIVE_SALES_TARGET CHECK (SALES_TARGET_AMT >= 0),
ETL_BATCH_ID               NUMBER(38, 0)    NOT NULL,
ETL_CREATED_LOAD_DT        DATE             NOT NULL,
ETL_MODIFIED_LOAD_DT       DATE             NOT NULL,
CONSTRAINT PK_SALES_TARGET PRIMARY KEY (SLS_REP_SK, MARKET_PRODUCT_HRCHY_SK, FISCAL_PERIOD)
USING INDEX
TABLESPACE DWH_NRM_INDEX
)
TABLESPACE DWH_NRM_DATA
;

由于约束名称冲突而返回以下错误

Error report -
SQL Error: ORA-02264: name already used by an existing constraint
02264. 00000 -  "name already used by an existing constraint"
*Cause:    The specified constraint name has to be unique.
*Action:   Specify a unique constraint name for the constraint.

正如其他问题建议使用查询，例如：

select * from ALL_constraints where constraint_name = 'PK_SALES_TARGET';

这没有返回任何结果（我已经尝试了上面的其他约束名称并且它们返回没问题）。

任何人都可以帮我找到我缺少的约束吗？

你认识3个约束

CONSTRAINT VALID_FISCAL_PERIOD 
CONSTRAINT POSITIVE_SALES_TARGET 
CONSTRAINT PK_SALES_TARGET

请检查它们是否已存在？

在oracle中创建一个返回约束名称冲突的表
