Question

我使用的是与MS Access交互的较旧的软件（2000年代）。我正在使用Python编写需要插入到软件中的MDB文件。我需要更新7个不同表的值才能获得期望值。对于所有7个表，我都使用以下代码：

def sql_cols(df):
    cols_aux = tuple(df.columns)
    cols_aux = str(cols_aux).replace("'","")
    cols_aux = cols_aux.replace(', DESC', ', [DESC]')
    return cols_aux


for k in range(len(df)):
    vals = tuple(list(df.iloc[k]))
    cols = sql_cols(df)
    action = 'INSERT INTO Strategy {columns} VALUES {values}'.format(columns = cols, values = str(vals).replace("'",''))
    cursor.execute(action)
    conn.commit()

在6个表中，此过程有效，但是我在INSERT INTO语句中不断获取（“ 42000”，“ [42000] [Microsoft] [ODBC Microsoft Access驱动程序]语法错误。（-3502）（SQLExecDirectW）”）最后一张桌子。该表的操作语句类似于：

'INSERT INTO Strategy (STRATGY_ID, NUMBUDGETS, PDISC_RATE, INC_IMPS, OPT_METHOD, OBJ_FUNC, MININCVAL, EFFFZONE, BUDGETPD, REPORTING, NUM_GROUPS, MATRIX_DEF, NAME, [DESC], FLT_CONRTE, WRK_CONRTE, NET_CONRTE, START_YEAR, END_YEAR, CURRENCY, FLEET, NETWORK, NUM_SECSEL, NUM_VEHSEL, ANAL_MODE, NUMPRJOPTS, NUMSECOPTS, INC_NMT, DOECONANAL, DISC_RATE, BASE_OPTN, ACCCOSTS, FATALCOST, INJURYCOST, DAMAGECOST, ALLACCCOST, ENERGY, EMISSIONS, ACCLEFFECT, LOGFILE, INCSENSTVY, NUMSENSCEN, DOASSETVAL, EXCVEHDATA, EXCPERDATA) 
VALUES (0, 0,  , 0, 1, 0, 0, 95, 0, -1, 0, 0, Road_Networks_PA,  , 1, 1, 1, 2019, 2038, Reais, Vehicles 2017, Road_Networks_PA, 157, 12, 0,  , 157, -1, -1, 6.49,  , 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,  , 0, -1, -1)'

我已经尝试将所有列都放在方括号[]中，但是它也没有用。谁能帮我解决这个问题？

编辑：按照戈登的建议，我更改了代码，但出现了相同的错误：

for k in range(len(df)):
    vals = tuple(list(df.iloc[k]))
    cols = sql_cols(df)
    action = 'INSERT INTO Strategy {columns} VALUES {values}'.format(columns = cols, values = str(vals))
    cursor.execute(action)
    conn.commit()

，动作语句为：

"INSERT INTO Strategy (STRATGY_ID, NUMBUDGETS, PDISC_RATE, INC_IMPS, OPT_METHOD, OBJ_FUNC, MININCVAL, EFFFZONE, BUDGETPD, REPORTING, NUM_GROUPS, MATRIX_DEF, NAME, [DESC], FLT_CONRTE, WRK_CONRTE, NET_CONRTE, START_YEAR, END_YEAR, CURRENCY, FLEET, NETWORK, NUM_SECSEL, NUM_VEHSEL, ANAL_MODE, NUMPRJOPTS, NUMSECOPTS, INC_NMT, DOECONANAL, DISC_RATE, BASE_OPTN, ACCCOSTS, FATALCOST, INJURYCOST, DAMAGECOST, ALLACCCOST, ENERGY, EMISSIONS, ACCLEFFECT, LOGFILE, INCSENSTVY, NUMSENSCEN, DOASSETVAL, EXCVEHDATA, EXCPERDATA) 
VALUES (0, 0, ' ', 0, 1, 0, 0, 95, 0, -1, 0, 0, 'Road_Networks_PA', ' ', 1, 1, 1, 2019, 2038, 'Reais', 'Vehicles 2017', 'Road_Networks_PA', 157, 12, 0, ' ', 157, -1, -1, 6.49, ' ', 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ' ', 0, -1, -1)"

Answer 1

CURRENCY是Access SQL中的保留字，因此，如果有一列具有该名称的列，则必须将其括在方括号中。即，这将失败，并显示“ INSERT INTO语句中的语法错误”。 ...

crsr.execute("INSERT INTO Strategy (CURRENCY) VALUES ('USD')")

...但这将起作用：

crsr.execute("INSERT INTO Strategy ([CURRENCY]) VALUES ('USD')")

Answer 2

正如戈登所说，您需要在字符串两边加上引号，而且逗号之间不应留有空格。尝试插入0或Null或更适合该字段的内容：

VALUES (0, 0, Null, 0,

Answer 3

VARCHAR列需要用引号引起来的值。尝试像这样构建查询：

INSERT INTO Strategy (STRATGY_ID, NUMBUDGETS, PDISC_RATE, INC_IMPS, OPT_METHOD, OBJ_FUNC, MININCVAL, EFFFZONE, BUDGETPD, REPORTING, NUM_GROUPS, MATRIX_DEF, NAME, [DESC], FLT_CONRTE, WRK_CONRTE, NET_CONRTE, START_YEAR, END_YEAR, CURRENCY, FLEET, NETWORK, NUM_SECSEL, NUM_VEHSEL, ANAL_MODE, NUMPRJOPTS, NUMSECOPTS, INC_NMT, DOECONANAL, DISC_RATE, BASE_OPTN, ACCCOSTS, FATALCOST, INJURYCOST, DAMAGECOST, ALLACCCOST, ENERGY, EMISSIONS, ACCLEFFECT, LOGFILE, INCSENSTVY, NUMSENSCEN, DOASSETVAL, EXCVEHDATA, EXCPERDATA) 
VALUES (0, 0, NULL , 0, 1, 0, 0, 95, 0, -1, 0, 0, "Road_Networks_PA", NULL , 1, 1, 1, 2019, 2038, "Reais", "Vehicles 2017", "Road_Networks_PA", 157, 12, 0, NULL, 157, -1, -1, 6.49, NULL, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL , 0, -1, -1)

为要保留为null或为空的列添加NULL或“”（空字符串）。
