问题 Why I get following results from sql-server? SELECT '' + 12 C1, CONVERT(int, '') C2, CASE WHEN '' = ' ' THEN 'equal' ELSE 'not equal' END C3 Sql-Server Fiddle demo --Results | C1 | C2 | C3 | ------------------- | 12 | 0 | equal | EDIT: C3 has been answered. Everyone answered thinking '' + 12 = 12 is string concatenation but it is a mathematical operation. It is not clear why ( NOT how) '' is converting to a 0 in sql-server. 回答1: SQL Server has a strange feature whereby, if two strings are

问题 I have table1 where Temp_ID column is combination of ID column values form table2 and table3 . Example: table1_id:table2_id {values like (1:1,2:2)} What I do in my Java code I need to use Temp_ID and split according to COLON(:), and then we can get table 2 and table 3 data using ID values obtained from split.

问题 SQL is not my strong suit, but I cannot figure out why this isn't working. I simply want to run a different AND statement based on a value. Specifically, I want to change the datePart in the dateDiff function if foo is = 0 SELECT foo, bar, test FROM table WHERE bar = 1, CASE WHEN foo = 0 AND dateDiff(dd, getDate(), 2 ) < test ELSE AND dateDiff(hh, getDate(), 2 ) < test END 回答1: Try this one - SELECT foo, bar, test FROM [table] WHERE bar = 1 AND ( ( foo = 0 AND DATEDIFF(dd, GETDATE(), 2 ) <

问题 I am trying to combine the results of several stored procedures into a single temporary table. The results of the various stored procedures have the same column structure. Essentially, I would like to UNION ALL the results of the various stored procedures. A significant fact: each of the stored procedures creates a temporary table to store its data and the results each returns are based on a select against the temporary table: create proc SP1 as . . <snip> . select * from #tmp -- a temporary

问题 I've created a build definition via visual studio online that builds an SSIS project (dtproj). The build appears to succeed but there is a warning that appears stating "dtproj is not supported by MSBuild and cannot be built". SSDT has been installed on the build server. Does anyone have any ideas why this warning would be showing up? 回答1: MSBuild cannot build the project file format that SSDT uses. It is a pre-msbuild visuals studio format. There's a hacky way to create an msbuild project

问题 In SSMS 2012, is there any way I can bind a keyboard shortcut (e.g. Ctrl - 5 ) so that I can highlight a qualified object name (e.g. master.sys.objects ) and invoke my own procedure using that object name as the argument? I know that this does work if I explicitly add quotes or brackets around the object name prior to using the keyboard shortcut (e.g. highlight the string 'sys.objects' , but this becomes tedious when wanting to use my shortcut easily by directly highlighting tables in

问题 Given SQL Server 2012, how can I insert control characters (the ones coded under ASCII 32, like TAB, CR, LF) in a nvarchar or varchar column from a SQL script? 回答1: Unless I miss something in the question you can do this using TSQL CHAR() function: INSERT INTO MyTable(ColName) VALUES(CHAR(13) + CHAR(10)) Will insert CR/LF. Same for other codes. Edit there is TSQL NCHAR() as well for Unicode characters. 回答2: Please note that the function may vary depending on the type of your column, using the
