SQL INSERT INTO 对我的 Access 数据库不起作用

SQL INSERT INTO does not work my Access database

我使用与 MS Access 交互的有点旧的软件(2000 年代)。我正在使用 Python 编写我需要插入到软件中的 MDB 文件。我需要更新 7 个不同 table 的值以获得预期值。对于所有 7 tables,我使用以下代码:

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 tables 中,此过程有效,但我不断收到 ('42000', '[42000] [Microsoft][ODBC Microsoft Access Driver] INSERT INTO 语句中的语法错误。(-3502) (SQLExecDirectW)') 在最后 table。 table 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放在方括号 [] 中,但它也不起作用。谁能帮我解决这个问题?

编辑: 按照 Gordon 的建议,我更改了代码,但出现了同样的错误:

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()

动作语句是:

"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)"

正如 Gordon 所说,您需要在字符串周围加上引号,并且您不应在逗号之间留空 space。尝试插入 0 或 Null 或更适合该字段的任何内容:

VALUES (0, 0, Null, 0,

VARCHAR 列需要用引号引起来的值。尝试构建您的查询:

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)

为要保留为空的列添加 NULL 或“”(空字符串)。

CURRENCY 是 Access SQL 中的保留字,因此如果您有一个具有该名称的列,则必须将其括在方括号中。也就是说,这将失败 "Syntax error in INSERT INTO statement." ...

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

...但这会起作用:

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