Question

I have a table containing around 100 columns, is it to possible to do a Select Replace on every column at the same time rather than typing out each column individually, i’m trying to trim the '"' of each field in the table.

SELECT
    REPLACE(*, '"', '')

Answer 1

DECLARE @tablename nvarchar(100)= 'Test'
DECLARE @col nvarchar(max)
SELECT @col = coalesce(@col + ',', 'select ' ) + 
case when data_type in ('varchar', 'char','nvarchar', 'nchar') then 
'replace('+column_name+' , ''"'', '''') '+' as [' + column_name + ']' else '[' + column_name + ']' end 
FROM INFORMATION_SCHEMA.COLUMNS a
WHERE table_name = @tablename
SET @col += ' from ' +  @tablename

EXEC (@col)
