\nStored Procedures are pre-compile objects which are compiled for first time and its compiled format is saved which executes (compiled code) whenever it is called. But Function is compiled and executed every time when it is called.<\/span><\/div>\n

\nBasic Difference<\/span><\/h2>\n
    \n
  1. \n
    \nFunction must return a value but in Stored Procedure it is optional( Procedure can return zero or n values).<\/span><\/div>\n<\/li>\n
  2. \n
    \nFunctions can have only input parameters for it whereas Procedures can have input\/output parameters .<\/span><\/div>\n<\/li>\n
  3. \n
    \nFunction takes one input parameter it is mandatory but Stored Procedure may take o to n input parameters..<\/span><\/div>\n<\/li>\n
  4. \n
    \nFunctions can be called from Procedure whereas Procedures cannot be called from Function.<\/span><\/div>\n
    \n<\/div>\n<\/li>\n<\/ol>\n

    \nAdvance Difference<\/span><\/h2>\n
      \n
    1. \n
      \nProcedure allows SELECT as well as DML(INSERT\/UPDATE\/DELETE) statement in it whereas Function allows only SELECT statement in it.<\/span><\/div>\n<\/li>\n
    2. \n
      \nProcedures can not be utilized in a SELECT statement whereas Function can be embedded in a SELECT statement.<\/span><\/div>\n<\/li>\n
    3. \n
      \nStored Procedures cannot be used in the SQL statements anywhere in the WHERE\/HAVING\/SELECT section whereas Function can be.<\/span><\/div>\n
      \n<\/div>\n<\/li>\n
    4. \n
      \nFunctions that return tables can be treated as another rowset. This can be used in JOINs with other tables.<\/span><\/div>\n<\/li>\n
    5. \n
      \nInline Function can be though of as views that take parameters and can be used in JOINs and other Rowset operations.<\/span><\/div>\n<\/li>\n
    6. \n
      \nException can be handled by try-catch block in a Procedure whereas try-catch block cannot be used in a Function.<\/span><\/div>\n<\/li>\n
    7. \n
      \nWe can go for Transaction Management in Procedure whereas we can’t go in Function.<\/span><\/div>\n<\/li>\n<\/ol>\n
