For example, my script for each database has to check if a certain table exist and if the length of a column in this table is less than certain number, increase it. And I can't see how to create such script without using apostrophes. How would you get around this ?


Assuminb that the column you want to check is some kind of CHARs:

execute sp_MsForEachDb 'IF NOT EXISTS(SELECT * 
                                         FROM ?.INFORMATION_SCHEMA.Columns 
                                      WHERE Table_Name = ''YourTableName''   AND
                                            COLUMN_NAME = ''YourColumnName'' AND
                                            CHARACTER_MAXIMUM_LENGTH = YourDesiredLength )
                          BEGIN
                               ALTER TABLE ?.dbo.YourTableName ALTER COLUMN YourColumnName varchar(YourDesiredLength)
                         END'
