Hi All, I have 480 Update SQL statements which I am executing using ADScript
component in Delphi 2010. Update SQL updates data in only one table called
MY_BOOK, but there is a join with MY_BOOK_HEADER table. Below is the Update
SQL, which is taking 81 seconds to execute all 480 Update SQL statements. Any
idea how could I improve the speed of these 480 Update SQL statements ? Update
SQL: Update MY_BOOK MB SET BOOK_NAME = 'Book Name1' , BOOK_DESCRIPTION = 'Book
Desfcription1' Where MB.BOOK_TYPE = 4 And Exists (Select 1 from MY_BOOK_HEADER
MBH Where Upper(Trim(MBH.HEADER_BOOK_CODE)) =
Upper(Trim('127518010109038')) And MBH.FK_BOOK_GROUP =
'{79B79C33-CE56-4084-912B-6DD9F70B3DC4}' And MBH.PK_BOOK_HEADER
= MB.SK_BOOK_HEADER &n bsp; ); Thanks In Advance. With Best Regards.
