Display all records with leading or trailing spaces

Question

I am looking for a SQL query (Using SQL 2008) to search various fields that I specify (or even all fields in particular tables) for leading or trailing spaces. I would like the output to be two columns with the following data:

ID Number, Data (that has the space), Field Name

Thanks for the help as usual!

Answer 1

You can use DATALENGTH

SELECT ID, Data, FieldName
FROM table
WHERE DATALENGTH(RTRIM(LTRIM(Data))) <> DATALENGTH(Data)

Answer 2

尝试：

select `ID Number`, `Data (that has the space)`, `Field Name` from tbl WHERE data like ' %' or data like '% '

Answer 3

I guess it depends exactly what you mean,by list of fields, the below code will do one at a time. However, if you want to give a list of 20 columns and check each, and output to a single list, that would take some recursion or some copy/paste unions.

select ID, DATA,Field_Name
from table
where DATA like '[ ]%'
        or DATA like '%[ ]'

The below will get you everything you are looking for with the exception of the ID. I wasn't sure if this was the column name or row or an Auto_ID or what. If its different in every table its a little tricky, but if its the same, you should be able to amend the below.

                DEALLOCATE KeyColumns_cursor;   


        FETCH NEXT FROM KeyTables_cursor into @Tables

        END

Answer 4

试试这个..这对我有用..它将找到以特殊字符开头的记录

SELECT * FROM ITEM_MASTER WHERE BARCODE LIKE '[^0-9a-zA-Z ]%'
