F# OleDb INSERT INTO 语句从访问中提取数据到链接 SQL Server 时出现语法错误

Question

我正在运行 F# 应用程序以将数据从 Access 表提取到链接的 SQL Server 表。这是查询结果:

INSERT INTO dbo_TempTerm (UnitID, PolicyTermYear, InsuredName, PolicyNumber, RenewalDate, CovATotal, CovBTotal, CovLTotal, DwellExtn, AllOtherPerilDeductible, MedPay, TotalPremium, HurricaneDeductible, Zone, Subzone, PercentCRC, PercentCRD, YearBuilt, RenYrs, PercentCFD, PercentHA, PercentMLD, GRP1, PercentNH, QCLM, RateV, CRI, AgentCode, AgentName, AFOCode, PolicyType, PolicyForm, OC, DateCreated)
SELECT [UNIT ID], [POLICY TERM YEAR], [INSURED NAME], [POLICY #], [RENEWAL DT], [COV A TOTAL], [COV B TOTAL], [COV L TOTAL], [DWELL EXTN], [ALL/OTHER PERIL DEDUCTIBLE], [MED PAY], [TOT PREMIUM], [HURR DED], ZONE, SUBZONE, [%CRC], [%CRD], [YR BLT], RENYRS, [%CFD], [%HA], [%MLD], GRP1, [%NH], QCLM, [RATE V], CRI, [AGENT CODE], [AGENT NAME], [AFO CODE], [POLICY TYPE], [POLICY FORM], OC, DateCreated
FROM tblPrior

查询在 Access 中解析并运行良好。但在我的应用程序中，它引发了一个错误:INSERT INTO 语句中的语法错误。

这是我的 F#，尽管我认为它不相关。

module Data

open System.Data
open System.Data.OleDb

type Period = Prior | Current

let Upload (p:Period) db =
    use conn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + db + ";Persist Security Info=False;")

    let execNonQuery s =
        let comm = new OleDbCommand(s, conn) in
        comm.ExecuteNonQuery() |> ignore

    let (table,proc) = match p with
                       | Prior   -> ("tblPrior"  ,"InitPriorTable")
                       | Current -> ("tblCurrent","InitCurrentTable")

    do conn.Open()

    let u = sprintf "INSERT INTO dbo_TempTerm (UnitID, PolicyTermYear, InsuredName, PolicyNumber, RenewalDate, CovATotal, CovBTotal, CovLTotal, DwellExtn, AllOtherPerilDeductible, MedPay, TotalPremium, HurricaneDeductible, Zone, Subzone, PercentCRC, PercentCRD, YearBuilt, RenYrs, PercentCFD, PercentHA, PercentMLD, GRP1, PercentNH, QCLM, RateV, CRI, AgentCode, AgentName, AFOCode, PolicyType, PolicyForm, OC, DateCreated) SELECT [UNIT ID], [POLICY TERM YEAR], [INSURED NAME], [POLICY #], [RENEWAL DT], [COV A TOTAL], [COV B TOTAL], [COV L TOTAL], [DWELL EXTN], [ALL/OTHER PERIL DEDUCTIBLE], [MED PAY], [TOT PREMIUM], [HURR DED], ZONE, SUBZONE, [%%CRC], [%%CRD], [YR BLT], RENYRS, [%%CFD], [%%HA], [%%MLD], GRP1, [%%NH], QCLM, [RATE V], CRI, [AGENT CODE], [AGENT NAME], [AFO CODE], [POLICY TYPE], [POLICY FORM], OC, DateCreated FROM %s" table
    // DEBUG.
    printfn "%s" u
    // DEBUG.
    execNonQuery u
    execNonQuery proc

Zone 和 DateCreated 均为 reserved words 。很难预测保留字何时会给 SQL 语句带来麻烦，但在我看来，OleDb 可能不太宽容，即更有可能因保留字而失败。查看将所有出现的这些名称括起来是否能让 INSERT 成功。

let u = sprintf "INSERT INTO dbo_TempTerm (UnitID, PolicyTermYear, InsuredName, PolicyNumber, RenewalDate, CovATotal, CovBTotal, CovLTotal, DwellExtn, AllOtherPerilDeductible, MedPay, TotalPremium, HurricaneDeductible, [Zone], Subzone, PercentCRC, PercentCRD, YearBuilt, RenYrs, PercentCFD, PercentHA, PercentMLD, GRP1, PercentNH, QCLM, RateV, CRI, AgentCode, AgentName, AFOCode, PolicyType, PolicyForm, OC, [DateCreated]) SELECT [UNIT ID], [POLICY TERM YEAR], [INSURED NAME], [POLICY #], [RENEWAL DT], [COV A TOTAL], [COV B TOTAL], [COV L TOTAL], [DWELL EXTN], [ALL/OTHER PERIL DEDUCTIBLE], [MED PAY], [TOT PREMIUM], [HURR DED], [ZONE], SUBZONE, [%%CRC], [%%CRD], [YR BLT], RENYRS, [%%CFD], [%%HA], [%%MLD], GRP1, [%%NH], QCLM, [RATE V], CRI, [AGENT CODE], [AGENT NAME], [AFO CODE], [POLICY TYPE], [POLICY FORM], OC, [DateCreated] FROM %s" table
