python SQL查詢與變量

Question

testid = 69 
query = """SELECT * FROM basic_info WHERE ownerid=%s""" 
cur.execute(query, testid) 
print cur.fetchone() 

您好，我收到一個整數錯誤，當試圖這樣做。我曾嘗試將testid轉換爲沒有運氣的字符串。

Answer 1

我更喜歡插入參數的這個方法，因爲這是非常清楚的：

query = "SELECT * FROM basic_info WHERE ownerid = %(testid)s" 
cur.execute(query, params = { 'testid': testid }) 

Answer 2

的Cursor.execute第二paraemter應該是一個序列（tuple或list）或映射（dict）：

testid = 69 
query = """SELECT * FROM basic_info WHERE ownerid=%s""" 
cur.execute(query, [testid]) # <-- 
print cur.fetchone()
