【问题描述】:
我正在尝试从 Automator 创建一个“.app”来运行一个简单的 python 脚本。当我在 Automator 中执行脚本时,会出现或多或少“检查您的操作属性并再次执行”的错误。
在历史记录中,它说“回溯(最近一次通话:)”。关键是这个脚本在终端会话中运行良好。
我的循环“While”似乎至少是一个错误,用于重命名数据库(见下文),因为我可以执行脚本到这个阶段。
管理 sqlite 数据库有问题吗?但我无法理解,因为终端没有问题。有什么遗漏吗?
我的python脚本:
#!/usr/bin/python
import sqlite3
import os.path
file_name = "newDB.data"
choice = ""
if os.path.isfile(file_name):
choice = raw_input("Erase DB? press [y] or [n]:\n")
if choice == "y":
print "erase"
while True:
try:
os.remove(file_name)
break
except OSError as e: # name the Exception `e`
print "Failed with:", e.strerror # look what it says
print "Error code:", e.code
if choice == "n":
print "Bye!"
exit()
# start sqlite connection
conn = sqlite3.connect("newDB.data")
c = conn.cursor()
# attach
c.execute("ATTACH database 'store1.data' AS db1")
c.execute("ATTACH database 'store2.data' AS db2")
# rename tables
while True:
try:
c.execute("ALTER TABLE db1.ZPATIENT RENAME TO table1")
print "table 1 renamed"
break
except:
c.execute("ALTER TABLE db1.table1 RENAME TO ZPATIENT")
print "except 1"
while True:
try:
c.execute("ALTER TABLE db2.ZPATIENT RENAME TO table2")
print "table 2 renamed"
break
except:
c.execute("ALTER TABLE db2.table2 RENAME TO ZPATIENT")
print "except 2"
# some information commands (START):
c.execute("SELECT * from table1")
print(c.fetchall())
c.execute("SELECT * from table2")
print(c.fetchall())
# some information commands (END)
#c.execute("create table ZPATIENT as select * from table1 union select * from table2") ---> first union action but some entries duplicated (one column changed?)
# remove some duplicated entries...
c.execute("create table ZPATIENT as select * from (select * from table1 union select * from table2) final group by ZDATECREATED")
c.execute("CREATE TABLE Z_PRIMARYKEY (Z_ENT int, Z_NAME text, Z_SUPER int, Z_MAX int)")
c.execute("CREATE TABLE Z_METADATA (Z_VERSION int, Z_UUID text, Z_PLIST BLOB)")
c.execute("SELECT count(*) FROM ZPATIENT")
result=c.fetchone()
number_of_rows=result[0]
print number_of_rows
start = 0
end = number_of_rows + 1
c.execute('SELECT * FROM ZPATIENT')
newresult=c.fetchall()
for row in newresult:
start += 1
end -= 1
print start
print end
# some information commands (START):
list_of_tuple = list(row)
list_of_tuple[0] = start
list_of_tuple[2] = end
row = tuple(list_of_tuple)
print row
# some information commands (END)
c.execute("UPDATE ZPATIENT SET Z_PK = ? WHERE rowid = ?", (start, start))
c.execute("UPDATE ZPATIENT SET Z_OPT = ? WHERE rowid = ?", (end, start))
c.execute("INSERT INTO Z_PRIMARYKEY (Z_ENT, Z_NAME, Z_SUPER, Z_MAX) VALUES (0, 'Patient', 0, ?)", (start,))
# close
conn.commit()
conn.close()
为了工作,我在同一个文件夹中有两个名为 store1.data 和 store2.data 的 sqlite 数据库...
如果有人有解决方案...我不知道是否有更简单的方法可以一键执行?
