问题 I need to insert a varchar in my table. The type in the table is a datetime so I need to convert it. I didn't think this would be to big of a problem however it keeps inserting 1900-01-01 00:00:00.000 instead of the date I want. When I do a select with my converted date it does show me the correct date. I'll show you the code: INSERT INTO Item (CategoryId, [Date], Content, CreatedOn) SELECT CategoryId, Convert(datetime, '28/11/2012', 103), Content, GetDate() FROM Item i JOIN Category c ON i

问题 I'm working on a C application that interacts with a mssql database running on Windows 2008 R2. I'm able to connect to the database and run specific queries, but when i use SQLBindParameter things fall apart. I found a post on stackoverflow that appears to be the same problem, but the solution doesnt appear to be the same (Problems getting SQLBindParameter to work in C++). According to C Data types SQL_C_CHAR is correct (https://msdn.microsoft.com/en-us/library/windows/desktop/ms714556(v=vs

问题 Hope someone can help - I am a novice SQL hacker (and very bad at it indeed!) I have two tables on SQL Server 2005 TABLE 1 and TABLE2: TABLE1 COL1 COL2 1 10 2 20 3 30 4 10 4 20 5 20 6 30 7 10 7 20 TABLE2 COL1 COL2 10 A 20 B 30 C COL2 in TABLE2 is a character representation of the numerical data in COL2 TABLE1. I hope this is understandable? I have worked out how to select COL1 and COL2 from TABLE1 and concatenate the results to show this: COL1 COL2Concat 1 10 2 20 3 30 4 10, 20 5 20 6 30 7 10
