Sean | DBISAM Latest - D2009
I am pulling the last of my hair out. The query below works so that is not the issue. I am importing a text file to a table. No issue there. I want to have the flexibility for the end user to specify the file name and path. Something to do with quotes, I am missing something. Any help appreciated, cheers, Sean FileNameToUse := datamodule1.tblSetupLocations.FieldByName('MOImportPath').AsString; //Filenametouse := AnsiQuotedStr(FilenametoUse,'"'); // doesn't work //Filenametouse := QuotedStr(FilenametoUse); // doesn't work //Filenametouse :='"C:\AMI\testdata\sdm.sdf"'; //This works Filenametouse :='[C:\AMI\testdata\sdm.sdf]'; //This works qryImport.close; qryImport.SQL.clear; qryImport.SQL.Add('IMPORT TABLE TempWeather from '); qryImport.SQL.Add(FilenametoUse); qryImport.SQL.Add('Columns(Date,MeanWindSpdLS,MaxWindSpdLS,MeanWindDirLS,MeanWindSpdHS,MaxWindSpdHS,MaxWindDirHS,MeanSeaLeve l1,MeanSeaLevel2,MeanSeaLevel3,'); qryImport.SQL.Add('MeanSeaTemp1,MeanSeaTemp2,MeanDewPoint,MeanWindChill,MaxWindChill,MeanWBGT,MaxWBGT,MeanWetBulb,MaxAirTemp ,MeanAirTemp,MinAirTemp,'); qryImport.SQL.Add('MeanRelHum,MeanBarPress,TotalRain,CumFDD,AddFDD,Spare,DirFreq1,DirFreq2,DirFreq3)'); showmessage(qryImport.sql.text); qryImport.ExecSQL; qryImport.Close; |

My initial thought was D2009 = Unicode so you have a problem there. How are you obtaining FilenametoUse, what is it defined as, string or ansistring, in the versions that don't work? What I'd suggest to help find out the problem is to build qryImport.SQL and then qryImport.SQL.SaveToFile(....), examine the text in the file, try running DBSys and see if you can spot the problem there.

This Filenametouse := AnsiQuotedStr(FilenametoUse,'"'); puts double quotes round the filename so I don't think that can be the problem. Roy Lambert [Team Elevate] |

Since I'd never used AnsiQuotedStr I tested it and the output looked fine to me which is why I suggested capturing the built up sql and having a shuftie. Roy Lambert |

Sean | Have tried several other combinations to no avail. Very strange behaviour. I would hate to have to hard wire the file names for these. Any other
ideas please send along.

Sean | This works below... SQL dump to text file...if likes double-quotes as expected - now how do I create just the double-quotes?
IMPORT TABLE TempWeather from "C:\AMI\testdata\sdm.sdf" Columns(Date,MeanWindSpdLS,MaxWindSpdLS,MeanWindDirLS,MeanWindSpdHS,MaxWindSpdHS,MaxWindDirHS,MeanSeaLevel1,MeanSeaLevel2,M eanSeaLevel3, MeanSeaTemp1,MeanSeaTemp2,MeanDewPoint,MeanWindChill,MaxWindChill,MeanWBGT,MaxWBGT,MeanWetBulb,MaxAirTemp,MeanAirTemp,MinAi rTemp, MeanRelHum,MeanBarPress,TotalRain,CumFDD,AddFDD,Spare,DirFreq1,DirFreq2,DirFreq3) Sean wrote: Have tried several other combinations to no avail.

Try cost dq ='"'; qryImport.SQL.Add(dq+FilenametoUse+dq); If that doesn't work then you have some really weird problem. Roy Lambert |

Sean | Bizarre concept to fool a poor system but for some reason your suggestion works. Thanks, I will try and work out why and advise. Maybe just the
allignment of the planets or something similary logical. Thanks for all the great help, as always, Sean Roy Lambert wrote: Sean Try cost dq ='"'; qryImport.SQL.Add(dq+FilenametoUse+dq); If that doesn't work then you have some really weird problem. Roy Lambert |
