问题 Given a number, how do you convert that to letters? 回答1: You can just translate your existing logic into a t-sql scalar function, like so: CREATE FUNCTION dbo.fnColumnNameFromIndex(@i int) RETURNS varchar(3) AS BEGIN DECLARE @dividend int, @letters varchar(3), @modulo int SET @dividend = @i SET @letters = '' WHILE @dividend > 0 BEGIN SET @modulo = (@dividend - 1) % 26 SET @letters = CHAR(65 + @modulo) + @letters SET @dividend = CONVERT(int, (@dividend - @modulo) / 26 ) END RETURN @letters;

ALTER PROCEDURE usp_debug_works] WITH RECOMPILE AS BEGIN /* Usage: EXEC [usp_debug_works] WITH RECOMPILE */ DECLARE @DATA_DT_ID AS int SET @DATA_DT_ID = 20081130 -- Stuff here that depends on DATA_DT_ID END You can see where I

问题 I have a primary key that I don't want to auto increment (for various reasons) and so I'm looking for a way to simply increment that field when I INSERT. By simply, I mean without stored procedures and without triggers, so just a series of SQL commands (preferably one command). Here is what I have tried thus far: BEGIN TRAN INSERT INTO Table1(id, data_field) VALUES ( (SELECT (MAX(id) + 1) FROM Table1), '[blob of data]'); COMMIT TRAN; * Data abstracted to use generic names and identifiers

问题 I have to rotate a given table from an SQL Server but a normal pivot just doesn't work (as far as i tried). So has anybody an idea how to rotate the table into the desired format? Just to make the problem more complicated, the list of given labels can vary and it is possible that a new label name can come into at any given time. Given Data ID | Label | Numerator | Denominator | Ratio ---+-----------------+-------------+---------------+-------- 1 | LabelNameOne | 41 | 10 | 4,1 1 | LabelNameTwo

问题 I need a case statement that allows partial matches. I get a syntax error, but am wondering if anything similar to this is possible. If not, my secondary solution is to re-write as a cursor... Example: SELECT CASE ColumnName WHEN 'value1' THEN 'answer1' WHEN 'value2' THEN 'answer2' WHEN LIKE '%TEST%' THEN 'answer3' END AS Answer FROM TableName 回答1: try this SELECT CASE WHEN ColumnName = 'value1' THEN 'answer1' WHEN ColumnName = 'value2' THEN 'answer2' WHEN ColumnName LIKE '%TEST%' THEN
