This is for newbies who struggle to understand how single quotes work in SQL Server I have seen newbies worrying why the following doesnt work

 
SELECT columns from mytable where col ='Lifco's'

When you specify a value which has single quote, you need to double it

 
SELECT columns from mytable where col ='Lifco''s'

The following may be helpful (Run and see the result)

 
SELECT '','''','''''','''''''',''''''''''

When you use a static sql and express a value in a single quote then first and last sigle quotes specify that the value is a string. Then within those single quotes every double single quotes represent a single single quote When you use a Dynamic sql then first and last sigle quotes specify that it is a dynamic sql. Then within those single quotes every double single quotes specify that it is a string.Then within those single quotes every four single quotes represent a single single quote Run and see the result

 
EXEC('SELECT '''','''''''','''''''''''','''''''''''''''',''''''''''''''''''''')
