问题 I'm having trouble inserting Unicode into a SQL Server database using Delphi ZeosLib and Delphi 7, and then reading the inserted value. I've created a simple test program that first inserts and then queries the inserted value. The test table schema: CREATE TABLE [dbo].[incominglog]( [message] [nvarchar](500) NULL ) ON [PRIMARY] I've upload the simple test program source (ZeosLib source included) - click here to download. I've also included ntwdblib.dll but you can use your own. The test

问题 I recently installed Zeos 6.6 stable on BDS2006 for both the Delphi and C++ personalities. In order to do so, and since Zeos is written in Delphi, I checked the " Generate all C++ Builder files " when building the packages. The problem I found was that, somehow, not all necessary .DCUs were generated during the building of the different packages. I finally worked around it by first building only for Delphi (which worked flawlessly) and then rebuilding for both Delphi and C++. Now, I am not

问题 I have a function in C++ that I am attempting to replicate in delphi: typedef double ANNcoord; // coordinate data type typedef ANNcoord* ANNpoint; // a point typedef ANNpoint* ANNpointArray; // an array of points bool readPt(istream &in, ANNpoint p) // read point (false on EOF) { for (int i = 0; i < dim; i++) { if(!(in >> p[i])) return false; } return true; } In Delphi I believe that I have correctly declared the data types.. (I could be wrong): type IPtr = ^IStream; // pointer to Istream

问题 im trying to make a multiple statement query like this : // without the second insert the query works fine. // i need 2 querys to work because later, i'll do inserts on different kind of tables. // that's why i need 2 querys, not a single query which insert 2 records. with ZQuery1 do begin SQL.Clear; SQL.Add('insert into client (name,age) values ('+QuotedStr('john')+','+QuotedStr('20')+');'); SQL.Add('insert into client (name,age) values ('+QuotedStr('doe')+','+QuotedStr('21')+');'); ExecSQL;

问题 I am using the latest Zeos with SQLite 3. It is generally going well, converting from MySQL, once we made all the persistent integer field TLargeInt . But when we use a column definition unsigned big int (the only unsigned type allowed according to https://www.sqlite.org/datatype3.html), Delphi is calling the resulting field a ftWidestring . 回答1: No, it does not "revert" to string, SQlite just stores the data as it is provided. As the documentation states: SQLite supports the concept of "type
