SQL INSERT INTO does not work my Access database


I work with a somewhat old software (2000's) that interfaces with MS Access. I am using Python to write the MDB files that I need to insert into the software. I need to update the values of 7 different tables in order to get the expected value. For all the 7 tables I am using the following code:

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()

In 6 tables this procedure works, however i keep getting ('42000', '[42000] [Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement. (-3502) (SQLExecDirectW)') in the last table. the action statement for that table is something like:

'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)'

I've already tried to ut all columns in square brackets, [], but it didn't work also. Can anyone help-me with this problem?

Edit: Following Gordon's advice, I altered the code, but the same error appears:

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()

and the action statement is:

"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)

Solution

  • CURRENCY is a reserved word in Access SQL, so if you have a column with that name you must enclose it in square brackets. That is, this will fail with "Syntax error in INSERT INTO statement." ...

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

    ... but this will work:

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