I am trying to execute the following SQL

But I am getting error "Invalid column name 'O'." What am I doing wrong.

try this and never use double quotes but two single quotes in T-SQL string in string:

SET @SQL='Select * from CUSTEVENT where  CustEvntOpenOrClose=''O''';
PRINT (@SQL);

Use two single-quote marks instead of a double-quote mark
Declare @sql nvarchar(100) 

SET @SQL='Select * from CUSTEVENT where  CustEvntOpenOrClose=''O''' 

SELECT @sql
