更新python中的查询执行

Question

I am executing this query on sql developer and it is working fine

update TABLE_X set COL_SID='19' where ID='1';

But when I am doing this via python code

cur=conn.cursor()
updt_query='update TABLE_X set COL_SID=? where ID=?'
cur.execute(updt_query,('19','1'))
cur.close()

I am getting error

cx_Oracle.DatabaseError: ORA-01036: illegal variable name/number

Please let me know where I am doing the mistake.

Answer 1

可能是ID是数字而不是字符串，所以您应该使用

 cur.execute(updt_query,(19,1))

Answer 2

I got a better way

cur=conn.cursor()
updt_query='update TABLE_X set COL_SID=:cs where ID=:id'
cur.execute(updt_query,{cs:'19',id:'1'})
cur.close()

Its done ! Thanks!
