Use the TRIM SQL function   If you are using SQL Server try     SELECT LTRIM RTRIM YourColumn   FROM YourTable

User · Answer

SQL Server does not support for Trim   function    But you can use LTRIM   to remove leading spaces and RTRIM   to remove trailing spaces   can use it as LTRIM RTRIM ColumnName   to remove both   update tablename set ColumnName  LTRIM RTRIM ColumnName

To just trim trailing spaces you should use  UPDATE     TableName SET     ColumnName   RTRIM ColumnName    However  if you want to trim all leading and trailing spaces then use this  UPDATE     TableName SET     ColumnName   LTRIM RTRIM ColumnName
