A tidy and efficient way of excluding rows with the same column value or equal to null

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :Sql Server
 

Good morning

I frequently use the pivot statement to generate columns I wish to compare, often looking for differences between the values in the columns. Quite often the pivot returns some null values which I am having some difficulty in comparing.

How to get column value difference of rows in same table

  
Dear all, I need a TSQL statement to find the difference of values of two rows in the same table, by taking into consideration some conditions. I have the following rowss in a table named table1 dbname  sqlinst     size1   ddate sqldb1    inst1        200    1/1/2009 sqldb1    inst1        250    1/1/2010 sqldb1    inst1        170    1/1/2008 sqldb2    inst2        300    1/1/2009 sqldb2    inst2        340    1/1/2010 I need to find the difference between size1 values, for columns where their dbname and sqlinst are the same. I also need to define in TSQL that the ddate of row from where I subtract (size1) from is 1/1/2010 and that the ddate of the row I subtract (size1) is 1/1/2009 (e.g. in the above example: for sqldb1 inst1, I need to perform 250-200 and ignore 170, and for sqldb2 inst2  340-300). Please let me know if you have a solution for this. A million thanks!

Searching a NVarChar Column with multiple wildcards returns all rows

  
I'm building a stored procedure to return a set of records, yes nothing big. The column is an NVarchar column and I'm using a select statement of Select * from Table1 where Column1 Like @Column1 Table is currently one record containing the words:  ***Some Test Word***  Is my test word I've set the value of @Column1 to: Some - no records returned Some% - no records returned %Some% - 1 record returned  % - 1 record returned *% - no records returned %*% - 1 record returned %Not Here% - 1 record returned   Can someone tell me why if I have a leading and trailing wildcard I will get all records returned?  Does it have something to do with the '*' characters in the field because some of my users are using these characters. I've also tried changing the select to: where RTRIM(Column1) Like @Column1 with the same result and where RTRIM(Column1) Like N'%' + @Column1 with the same result   What way should I give a user the way to search for a substring inside of an NVarchar field? Oh, I tried using the Substring function and got the same result. Thanks Mike

Update nullable column in db to null?

  
Can anyone reliably get the EDS to save a nullable column to the databse as a "null" when bound to any of the controls such as "FormView"? I have tried using several different UpdateParameters (Session, ControlParamater, Parameter,  etc). I have tried setting "ConvertEmptyStringToNull" to true and leaving the property off entirely. Nothing works. On my "Inserts" it works fine. (I have made sure the column is set to nullable = true in the Entity Designer.....)
