我正在运行以下查询.但得到ORA-12899.尝试插入的字符串的长度是30.

INSERT INTO TABLE1 SELECT * FROM temp_Table1 where LENGTH(column1)=30;

SQL Error: ORA-12899:value too large for column "TABLE1"."column1" (actual: 31, maximum: 30)


select column1 from temp_Table1 where LENGTH(column1)=30;

Desc temp_Table1

column1 VARCHAR2(30)

Desc Table1

column1 VARCHAR2(30)
