Dynamic Update/insert statement

Posted on 2006-11-02

Last Modified: 2011-10-03
I am attempting to create an update/insert statement dynamically based on information that exists in another table (it lists the column names in another table to be updated). The columns in that table are added to the array ColumnsInAccess and we are attempting to devise the statements. I keep getting the error "one or more values do not have required parameters." Please any help would be awesome. First listed is a debug.Writeline of the statements generated then the code in which it is being created.

Thanks





UPDATE NETWORKDATA SET 'CustomerName' = @CustomerName, SET 'DateEntry' = @DateEntry, SET 'HourNo' = @HourNo, SET 'NetBIOSSMBTx' = @NetBIOSSMBTx, SET 'NetBIOSSMBRx' = @NetBIOSSMBRx, SET 'LotusNotesTx' = @LotusNotesTx, SET 'LotusNotesRx' = @LotusNotesRx, SET 'WebTx' = @WebTx, SET 'WebRx' = @WebRx, SET 'CitrixTx' = @CitrixTx, SET 'CitrixRx' = @CitrixRx, SET 'ServiceTx' = @ServiceTx, SET 'ServiceRx' = @ServiceRx, SET 'VoiceVideoTx' = @VoiceVideoTx, SET 'VoiceVideoRx' = @VoiceVideoRx, SET 'GopherTx' = @GopherTx, SET 'GopherRx' = @GopherRx, SET 'RoutingTx' = @RoutingTx, SET 'RoutingRx' = @RoutingRx, SET 'TelnetTx' = @TelnetTx, SET 'TelnetRx' = @TelnetRx, SET 'SNMPTx' = @SNMPTx, SET 'SNMPRx' = @SNMPRx, SET 'OtherTx' = @OtherTx, SET 'OtherRx' = @OtherRx, SET 'PrintingTx' = @PrintingTx, SET 'PrintingRx' = @PrintingRx, SET 'SAPTx' = @SAPTx, SET 'SAPRx' = @SAPRx, SET 'NWIPTx' = @NWIPTx, SET 'NWIPRx' = @NWIPRx, SET 'DatabaseTx' = @DatabaseTx, SET 'DatabaseRx' = @DatabaseRx, SET 'FTPTx' = @FTPTx, SET 'FTPRx' = @FTPRx, SET 'TFTPTx' = @TFTPTx, SET 'TFTPRx' = @TFTPRx, SET 'BOOTPTx' = @BOOTPTx, SET 'BOOTPRx' = @BOOTPRx, SET 'TunnelTx' = @TunnelTx, SET 'TunnelRx' = @TunnelRx, SET 'MailTx' = @MailTx, SET 'MailRx' = @MailRx, SET 'FileShareTx' = @FileShareTx, SET 'FileShareRx' = @FileShareRx, SET 'MessageTx' = @MessageTx, SET 'MessageRx' = @MessageRx, SET 'StreamingTx' = @StreamingTx, SET 'StreamingRx' = @StreamingRx, SET 'T120Tx' = @T120Tx, SET 'T120Rx' = @T120Rx, SET 'SSHTx' = @SSHTx, SET 'SSHRx' = @SSHRx, SET 'PeopleSoftTx' = @PeopleSoftTx, SET 'PeopleSoftRx' = @PeopleSoftRx, SET 'NNTPTx' = @NNTPTx, SET 'NNTPRx' = @NNTPRx, SET 'FIXTx' = @FIXTx, SET 'FIXRx' = @FIXRx, SET 'DLSWTx' = @DLSWTx, SET 'DLSWRx' = @DLSWRx, SET 'DCERPCTx' = @DCERPCTx, SET 'DCERPCRx' = @DCERPCRx, SET 'CustomAppsTx' = @CustomAppsTx, SET 'CustomAppsRx' = @CustomAppsRx, SET 'VinesTx' = @VinesTx, SET 'VinesRx' = @VinesRx, SET 'SNATx' = @SNATx, SET 'SNARx' = @SNARx, SET 'IPXTx' = @IPXTx, SET 'IPXRx' = @IPXRx, SET 'DecNetTx' = @DecNetTx, SET 'DecNetRx' = @DecNetRx, SET 'AppleTx' = @AppleTx, SET 'AppleRx' = @AppleRx, SET 'TotalTx' = @TotalTx, SET 'TotalRx' = @TotalRx WHERE @CustomerName, @DateEntry, @HourNo, @NetBIOSSMBTx, @NetBIOSSMBRx, @LotusNotesTx, @LotusNotesRx, @WebTx, @WebRx, @CitrixTx, @CitrixRx, @ServiceTx, @ServiceRx, @VoiceVideoTx, @VoiceVideoRx, @GopherTx, @GopherRx, @RoutingTx, @RoutingRx, @TelnetTx, @TelnetRx, @SNMPTx, @SNMPRx, @OtherTx, @OtherRx, @PrintingTx, @PrintingRx, @SAPTx, @SAPRx, @NWIPTx, @NWIPRx, @DatabaseTx, @DatabaseRx, @FTPTx, @FTPRx, @TFTPTx, @TFTPRx, @BOOTPTx, @BOOTPRx, @TunnelTx, @TunnelRx, @MailTx, @MailRx, @FileShareTx, @FileShareRx, @MessageTx, @MessageRx, @StreamingTx, @StreamingRx, @T120Tx, @T120Rx, @SSHTx, @SSHRx, @PeopleSoftTx, @PeopleSoftRx, @NNTPTx, @NNTPRx, @FIXTx, @FIXRx, @DLSWTx, @DLSWRx, @DCERPCTx, @DCERPCRx, @CustomAppsTx, @CustomAppsRx, @VinesTx, @VinesRx, @SNATx, @SNARx, @IPXTx, @IPXRx, @DecNetTx, @DecNetRx, @AppleTx, @AppleRx, @TotalTx, @TotalRx)

UPDATE:

Error has now changed to "Parameter @HourNo has no default value." which is the first column listed in the array "ColumnsInAccess"

All those words that start with "@" are sql server variables and they need to be set to a value.  The update statement you built would work well inside a stored procedure (which could take all the @variables as parameters).

in both the update and insert or just update? Would you mean I would loop through the dataset and put the value of the row at @?

I figured it out. I add each row indivudually and create the insert statement with those values to insert.
